It focuses its API on common use-cases to provide a smooth developer experience whilst allowing third parties to extend its features via plugins.\n\nPlease note that this SDK has been re-implemented from scratch and is still in active development. This means **some of the core API and interfaces might change from one version to another**. However, feel free to use it and provide some early feedback if you wish to contribute to the direction of this project.\n\n## Installation\n```sh\nnpm install @metaplex-foundation/js @solana/web3.js\n```\n\n🔥 **Pro Tip**: Check out our examples and starter kits on the [\"JS Examples\" repository](https://github.com/metaplex-foundation/js-examples).\n\n## Setup\nThe entry point to the JavaScript SDK is a `Metaplex` instance that will give you access to its API.\n\nIt accepts a `Connection` instance from `@solana/web3.js` that will be used to communicate with the cluster.\n\n```ts\nimport { Metaplex } from \"@metaplex-foundation/js\";\nimport { Connection, clusterApiUrl } from \"@solana/web3.js\";\n\nconst connection = new Connection(clusterApiUrl(\"mainnet-beta\"));\nconst metaplex = new Metaplex(connection);\n```\n\nOn top of that, you can customise who the SDK should interact on behalf of and which storage provider to use when uploading assets. We refer to these as \"Identity Drivers\" and \"Storage Drivers\" respectively. You may change these drivers by calling the `use` method on the Metaplex instance like so. We'll see all available drivers in more detail below.\n\n```ts\nimport { Metaplex, keypairIdentity, bundlrStorage } from \"@metaplex-foundation/js\";\nimport { Connection, clusterApiUrl, Keypair } from \"@solana/web3.js\";\n\nconst connection = new Connection(clusterApiUrl(\"mainnet-beta\"));\nconst wallet = Keypair.generate();\n\nconst metaplex = Metaplex.make(connection)\n    .use(keypairIdentity(wallet))\n    .use(bundlrStorage());\n```\n\nNotice how you can create a `Metaplex` instance using `Metaplex.make(...)` instead of `new Metaplex(...)` in order to make the fluent API more readable.\n\n## Usage\nOnce properly configured, that `Metaplex` instance can be used to access modules providing different sets of features. Currently, there is only one documented NFT module that can be accessed via the `nfts()` method. From that module, you will be able to find, create and update NFTs with more features to come.\n\nFor instance, here is how you can fetch an NFT by its mint address.\n\n```ts\nconst nft = await metaplex.nfts().findByMint({ mintAddress });\n```\n\nWe call `findByMint` an **Operation** on the NFT Module. Each operation accepts an input object as its first argument that is defined by the operation itself. Additionally, each operation accepts a second optional argument that is shared by all operations and used for more generic options. For instance, you may pass an `AbortSignal` to this second argument to cancel the operation before it finishes — similarly to how you would cancel an HTTP request.\n\n```ts\n// Create an AbortController that aborts in 100ms.\nconst abortController = new AbortController();\nsetTimeout(() =\u003e abortController.abort(), 100);\n\n// Pass the AbortController's signal to the operation.\nconst nft = await metaplex.nfts().findByMint({ mintAddress }, {\n    signal: abortController.signal\n});\n```\n\nNow, let’s look into the NFT module in a bit more detail before moving on to the identity and storage drivers.\n\n## NFTs\nThe NFT module can be accessed via `metaplex.nfts()` and provides the following methods.\n\n- [`findByMint`](#findByMint)\n- [`findAllByMintList`](#findAllByMintList)\n- [`load`](#load)\n- [`findAllByOwner`](#findAllByOwner)\n- [`findAllByCreator`](#findAllByCreator)\n- [`uploadMetadata`](#uploadMetadata)\n- [`create`](#create)\n- [`update`](#update)\n- [`printNewEdition`](#printNewEdition)\n- [`use`](#useNft)\n\nAnd the following model, either returned or used by the above methods.\n\n- [The `Nft` model](#the-nft-model)\n\nYou may also be interested in browsing [the API References of that module](https://metaplex-foundation.github.io/js/classes/js.NftClient.html).\n\n### findByMint\n\nThe `findByMint` method accepts a `mintAddress` public key and returns [an `Nft` object](#the-nft-model).\n\n```ts\nconst mintAddress = new PublicKey(\"ATe3DymKZadrUoqAMn7HSpraxE4gB88uo1L9zLGmzJeL\");\n\nconst nft = await metaplex.nfts().findByMint({ mintAddress });\n```\n\nThe returned `Nft` object will have its JSON metadata already loaded so you can, for instance, access its image URL like so (provided it is present in the downloaded metadata).\n\n```ts\nconst imageUrl = nft.json.image;\n```\n\nSimilarly, the `Edition` information of the NFT — original or printed — is also available on the object via the `edition` property. Its type depends on whether the NFT is the original or a printed edition.\n\n```ts\nconst editionAddress = nft.edition.address;\n\nif (nft.edition.isOriginal) {\n    const totalPrintedNfts = nft.edition.supply;\n    const maxNftsThatCanBePrinted = nft.edition.maxSupply;\n} else {\n    const mintAddressOfOriginalNft = nft.edition.parent;\n    const editionNumber = nft.edition.number;\n}\n```\n\nYou can [read more about the `NFT` model below](#the-nft-model).\n\n### findAllByMintList\n\nThe `findAllByMintList` operation accepts an array of mint addresses and returns an array of NFTs. However, `null` values will be returned for each provided mint address that is not associated with an NFT.\n\nNote that this is much more efficient than calling `findByMint` for each mint in the list as the SDK can optimise the query and fetch multiple NFTs in much fewer requests.\n\n```ts\nconst [nftA, nftB] = await metaplex.nfts().findAllByMintList({\n    mints: [mintA, mintB]\n});\n```\n\nNFTs retrieved via `findAllByMintList` may be of type `Metadata` rather than `Nft`.\n\nWhat this means is they won't have their JSON metadata loaded because this would require one request per NFT and could be inefficient if you provide a long list of mint addresses. Additionally, you might want to fetch these on-demand, as the NFTs are being displayed on your web app for instance. The same goes for the `edition` property which requires an extra account to fetch and might be irrelevant until the user clicks on the NFT.\n\nNote that, since plugins can swap operation handlers with their own implementations, it is possible that a plugin relying on indexers return an array of `Nft`s directly instead of `Metadata`s. The default implementation though, will return `Metadata`s.\n\nThus, if you want to load the `json` and/or `edition` properties of an NFT, you need to load that `Metadata` into an `Nft`. Which you can do with the next operation.\n\n### load\n\nFor performance reasons, when fetching NFTs in bulk, you may receive `Metadata`s which exclude the JSON Metadata and the Edition information of the NFT. In order to transform a `Metadata` into an `Nft`, you may use the `load` operation like so.\n\n```ts\nconst nft = await metaplex.nfts().load({ metadata });\n```\n\nThis will give you access to the `json` and `edition` properties of the NFT as explained in [the NFT model documentation](#the-nft-model).\n\n### findAllByOwner\n\nThe `findAllByOwner` method accepts a public key and returns all NFTs owned by that public key.\n\n```ts\nconst myNfts = await metaplex.nfts().findAllByOwner({\n    owner: metaplex.identity().publicKey\n});\n```\n\nSimilarly to `findAllByMintList`, the returned NFTs may be `Metadata`s.\n\n### findAllByCreator\n\nThe `findAllByCreator` method accepts a public key and returns all NFTs that have that public key registered as their first creator. Additionally, you may provide an optional position parameter to match the public key at a specific position in the creator list.\n\n```ts\nconst nfts = await metaplex.nfts().findAllByCreator({ creator });\nconst nfts = await metaplex.nfts().findAllByCreator({ creator, position: 1 }); // Equivalent to the previous line.\nconst nfts = await metaplex.nfts().findAllByCreator({ creator, position: 2 }); // Now matching the second creator field.\n```\n\nSimilarly to `findAllByMintList`, the returned NFTs may be `Metadata`s.\n\n### uploadMetadata\n\nWhen creating or updating an NFT, you will need a URI pointing to some JSON Metadata describing the NFT. Depending on your requirement, you may do this on-chain or off-chain.\n\nIf your JSON metadata is not already uploaded, you may do this using the SDK via the `uploadMetadata` method. It accepts a metadata object and returns the URI of the uploaded metadata. Where exactly the metadata will be uploaded depends on the selected `StorageDriver`.\n\n```ts\nconst { uri } = await metaplex.nfts().uploadMetadata({\n    name: \"My NFT\",\n    description: \"My description\",\n    image: \"https://arweave.net/123\",\n});\n\nconsole.log(uri) // https://arweave.net/789\n```\n\nSome properties inside that metadata object will also require you to upload some assets to provide their URI — such as the `image` property on the example above.\n\nTo make this process easier, the `uploadMetadata` method will recognise any instances of `MetaplexFile` within the provided object and upload them in bulk to the current storage driver. It will then create a new version of the provided metadata where all instances of `MetaplexFile` are replaced with their URI. Finally, it will upload that replaced metadata to the storage driver and return it.\n\n```ts\n// Assuming the user uploaded two assets via an input field of type \"file\".\nconst browserFiles = event.target.files;\n\nconst { uri, metadata } = await metaplex.nfts().uploadMetadata({\n    name: \"My NFT\",\n    image: await toMetaplexFileFromBrowser(browserFiles[0]),\n    properties: {\n        files: [\n            {\n                type: \"video/mp4\",\n                uri: await toMetaplexFileFromBrowser(browserFiles[1]),\n            },\n        ]\n    }\n});\n\nconsole.log(metadata.image) // https://arweave.net/123\nconsole.log(metadata.properties.files[0].uri) // https://arweave.net/456\nconsole.log(uri) // https://arweave.net/789\n```\n\nNote that `MetaplexFile`s can be created in various different ways based on where the file is coming from. You can [read more about `MetaplexFile` objects and how to use them here](#MetaplexFile).\n\n### create\n\nThe `create` method accepts [a variety of parameters](https://metaplex-foundation.github.io/js/types/js.CreateNftInput.html) that define the on-chain data of the NFT. The only parameters required are its `name`, its `sellerFeeBasisPoints` — i.e. royalties — and the `uri` pointing to its JSON metadata — remember that you can use `uploadMetadata` to get that URI. All other parameters are optional as the SDK will do its best to provide sensible default values.\n\nHere's how you can create a new NFT with minimum configuration.\n\n```ts\nconst { nft } = await metaplex.nfts().create({\n    uri: \"https://arweave.net/123\",\n    name: \"My NFT\",\n    sellerFeeBasisPoints: 500, // Represents 5.00%.\n});\n```\n\nThis will take care of creating the mint account, the associated token account, the metadata PDA and the original edition PDA (a.k.a. the master edition) for you.\n\nAdditionally, since no other optional parameters were provided, it will do its best to provide sensible default values for the rest of the parameters. Namely:\n- Since no owner, mint authority or update authority were provided, the “identity” of the SDK will be used by default for these parameters. Meaning the SDK's identity will be the owner of that new NFT.\n- It will also default to setting the identity as the first and only creator with a 100% share.\n- It will default to making the NFT mutable — meaning the update authority will be able to update it later on.\n\nIf some of these default parameters are not suitable for your use case, you may provide them explicitly when creating the NFT. [Here is the exhaustive list of parameters](https://metaplex-foundation.github.io/js/types/js.CreateNftInput.html) accepted by the `create` method.\n\n### update\n\nThe `update` method accepts an `Nft` object and a set of parameters to update on the NFT.\n\nFor instance, here is how you would change the on-chain name of an NFT.\n\n```ts\nawait metaplex.nfts().update({ \n    nftOrSft: nft,\n    name: \"My Updated Name\"\n});\n```\n\nAnything that you don’t provide in the parameters will stay unchanged. Note that it will not fetch the updated NFT in order to avoid the extra HTTP call if you don't need it. If you do need to refresh the NFT instance to access the latest data, you may do that using the `refresh` operation.\n\n```ts\nconst updatedNft = await metaplex.nfts().refresh(nft);\n```\n\nIf you’d like to change the JSON metadata of the NFT, you’d first need to upload a new metadata object using the `uploadMetadata` method and then use the provided URI to update the NFT.\n\n```ts\nconst { uri: newUri } = await metaplex.nfts().uploadMetadata({\n    ...nft.json,\n    name: \"My Updated Metadata Name\",\n    description: \"My Updated Metadata Description\",\n});\n\nawait metaplex.nfts().update({ \n    nftOrSft: nft,\n    uri: newUri\n});\n```\n\n### printNewEdition\n\nThe `printNewEdition` method requires the mint address of the original NFT and returns a brand-new NFT printed from the original edition.\n\nThis is how you would print a new edition of the `originalNft` NFT.\n\n```ts\nconst { nft: printedNft } = await metaplex.nfts().printNewEdition({\n    originalMint: originalNft.mint\n});\n```\n\nBy default, it will print using the token account of the original NFT as proof of ownership, and it will do so using the current `identity` of the SDK. You may customise all of these parameters by providing them explicitly.\n\n```ts\nawait metaplex.nfts().printNewEdition({\n    originalMint,\n    newMint,                   // Defaults to a brand-new Keypair.\n    newUpdateAuthority,        // Defaults to the current identity.\n    newOwner,                  // Defaults to the current identity.\n    originalTokenAccountOwner, // Defaults to the current identity.\n    originalTokenAccount,      // Defaults to the associated token account of the current identity.\n});\n```\n\nNotice that, by default, update authority will be transferred to the metaplex identity. If you want the printed edition to retain the update authority of the original edition, you might want to provide it explicitly like so.\n\n```ts\nawait metaplex.nfts().printNewEdition({\n    originalMint,\n    newUpdateAuthority: originalNft.updateAuthorityAddress,\n});\n```\n\n### useNft\n\nThe `use` method requires [a usable NFT](https://docs.metaplex.com/programs/token-metadata/using-nfts) and will decrease the amount of uses by one. You may also provide the `numberOfUses` parameter, if you'd like to use it more than once in the same instruction.\n\n```ts\nawait mx.nfts().use({ mintAddress: nft.address }); // Use once.\nawait mx.nfts().use({ mintAddress: nft.address, numberOfUses: 3 }); // Use three times.\n```\n\n### The `Nft` model\n\nAll of the methods above either return or interact with an `Nft` object. The `Nft` object is a read-only data representation of your NFT that contains all the information you need at the top level.\n\nHere is an overview of the properties that are available on the `Nft` object.\n\n```ts\ntype Nft = Readonly\u003c{\n    model: 'nft';\n    address: PublicKey;\n    metadataAddress: Pda;\n    updateAuthorityAddress: PublicKey;\n    json: Option\u003cJson\u003e;\n    jsonLoaded: boolean;\n    name: string;\n    symbol: string;\n    uri: string;\n    isMutable: boolean;\n    primarySaleHappened: boolean;\n    sellerFeeBasisPoints: number;\n    editionNonce: Option\u003cnumber\u003e;\n    creators: Creator[];\n    tokenStandard: Option\u003cTokenStandard\u003e;\n    collection: Option\u003c{\n        address: PublicKey;\n        verified: boolean;\n    }\u003e;\n    collectionDetails: Option\u003c{\n        version: 'V1';\n        size: BigNumber;\n    }\u003e;\n    uses: Option\u003c{\n        useMethod: UseMethod;\n        remaining: BigNumber;\n        total: BigNumber;\n    }\u003e;\n    mint: {\n        model: 'mint';\n        address: PublicKey;\n        mintAuthorityAddress: Option\u003cPublicKey\u003e;\n        freezeAuthorityAddress: Option\u003cPublicKey\u003e;\n        decimals: number;\n        supply: SplTokenAmount;\n        isWrappedSol: boolean;\n        currency: SplTokenCurrency;\n    };\n    edition:\n        | {\n            model: 'nftEdition';\n            isOriginal: true;\n            address: PublicKey;\n            supply: BigNumber;\n            maxSupply: Option\u003cBigNumber\u003e;\n        }\n        | {\n            model: 'nftEdition';\n            isOriginal: false;\n            address: PublicKey;\n            parent: PublicKey;\n            number: BigNumber;\n        };\n}\u003e\n```\n\nAdditionally, the SDK may sometimes return a `Metadata` instead of an `Nft` object. The `Metadata` model contains the same data as the `Nft` model but it excludes the following properties: `json`, `mint` and `edition`. This is because they are not always needed and/or can be expensive to load. Therefore, the SDK uses the following rule of thumb:\n- If you're only fetching one NFT — e.g. by using `findByMint` — then you will receive an `Nft` object containing these properties.\n- If you're fetching multiple NFTs — e.g. by using `findAllByMintLint` — then you will receive an array of `Metadata` that do not contain these properties.\n\nYou may obtain an `Nft` object from a `Metadata` object by using [the `load` method](#load) explained above,\n\n## Candy Machines\nThe Candy Machine module can be accessed via `metaplex.candyMachinesV2()` and provides the following documented methods.\n\n- [`findMintedNfts(candyMachine, options)`](#findMintedNfts)\n\nThe Candy Machine actually contains more features and models but we are still in the process of documenting them.\n\n### findMintedNfts\n\nThe `findMintedNfts` method accepts the public key of a Candy Machine and returns all NFTs that have been minted from that Candy Machine so far.\n\nBy default, it will assume you're providing the public key of a Candy Machine v2. If you want to use a different version, you can provide the version as the second parameter.\n\n```ts\nconst nfts = await metaplex.candyMachinesV2().findMintedNfts({ candyMachine });\nconst nfts = await metaplex.candyMachinesV2().findMintedNfts({ candyMachine, version: 2 }); // Equivalent to the previous line.\nconst nfts = await metaplex.candyMachinesV2().findMintedNfts({ candyMachine, version: 1 }); // Now finding NFTs for Candy Machine v1.\n```\n\nNote that the current implementation of this method delegates to `nfts().findAllByCreator()` whilst fetching the appropriate PDA for Candy Machines v2.\n\nSimilarly to `findAllByMintList`, the returned NFTs may be `Metadata`s.\n\n## Identity\nThe current identity of a `Metaplex` instance can be accessed via `metaplex.identity()` and provide information on the wallet we are acting on behalf of when interacting with the SDK.\n\nThis method returns an identity client with the following interface.\n\n```ts\nclass IdentityClient {\n    driver(): IdentityDriver;\n    setDriver(newDriver: IdentityDriver): void;\n    publicKey: PublicKey;\n    secretKey?: Uint8Array;\n    signMessage(message: Uint8Array): Promise\u003cUint8Array\u003e;\n    verifyMessage(message: Uint8Array, signature: Uint8Array): boolean;\n    signTransaction(transaction: Transaction): Promise\u003cTransaction\u003e;\n    signAllTransactions(transactions: Transaction[]): Promise\u003cTransaction[]\u003e;\n    equals(that: Signer | PublicKey): boolean;\n    hasSecretKey(): this is KeypairSigner;\n}\n```\n\nThe `IdentityClient` delegates to whichever `IdentityDriver` is currently set to provide this set of methods. Thus, the implementation of these methods depends on the concrete identity driver being used. For instance, in the CLI, these methods will directly use a key pair whereas, in the browser, they will delegate to a wallet adapter.\n\nLet’s have a quick look at the concrete identity drivers available to us.\n\n### guestIdentity\n\nThe `guestIdentity` driver is the default driver and requires no parameter. It is essentially a `null` driver that can be useful when we don’t need to send any signed transactions.\n\n```ts\nimport { guestIdentity } from \"@metaplex-foundation/js\";\n\nmetaplex.use(guestIdentity());\n```\n\nIf we try to sign a message or a transaction using this driver, an error will be thrown.\n\n### keypairIdentity\n\nThe `keypairIdentity` driver accepts a `Keypair` object as a parameter. This is useful when using the SDK locally such as within CLI applications.\n\n```ts\nimport { keypairIdentity } from \"@metaplex-foundation/js\";\nimport { Keypair } from \"@solana/web3.js\";\n\n// Load a local keypair.\nconst keypairFile = fs.readFileSync('/Users/username/.config/solana/id.json');\nconst keypair = Keypair.fromSecretKey(Buffer.from(JSON.parse(keypairFile.toString())));\n\n// Use it in the SDK.\nmetaplex.use(keypairIdentity(keypair));\n```\n\n### walletAdapterIdentity\n\nThe `walletAdapterIdentity` driver accepts a wallet adapter as defined by the [“wallet-adapter” repo from Solana Labs](https://github.com/solana-labs/wallet-adapter). This is useful when using the SDK in a web application that requires the user to manually approve transactions.\n\n```ts\nimport { walletAdapterIdentity } from \"@metaplex-foundation/js\";\nimport { useWallet } from '@solana/wallet-adapter-react';\n\nconst wallet = useWallet();\nmetaplex.use(walletAdapterIdentity(wallet));\n```\n\n## Storage\nYou may access the storage client using `metaplex.storage()` which will give you access to the following interface.\n\n```ts\nclass StorageClient {\n    driver(): StorageDriver\n    setDriver(newDriver: StorageDriver): void;\n    getUploadPriceForBytes(bytes: number): Promise\u003cAmount\u003e;\n    getUploadPriceForFile(file: MetaplexFile): Promise\u003cAmount\u003e;\n    getUploadPriceForFiles(files: MetaplexFile[]): Promise\u003cAmount\u003e;\n    upload(file: MetaplexFile): Promise\u003cstring\u003e;\n    uploadAll(files: MetaplexFile[]): Promise\u003cstring[]\u003e;\n    uploadJson\u003cT extends object = object\u003e(json: T): Promise\u003cstring\u003e;\n    download(uri: string, options?: RequestInit): Promise\u003cMetaplexFile\u003e;\n    downloadJson\u003cT extends object = object\u003e(uri: string, options?: RequestInit): Promise\u003cT\u003e;\n}\n```\n\nSimilarly to the `IdentityClient`, the `StorageClient` delegates to the current `StorageDriver` when executing these methods. We'll take a look at the storage drivers available to us, but first, let's talk about the `MetaplexFile` type which is being used throughout the `StorageClient` API.\n\n### MetaplexFile\n\nThe `MetaplexFile` type is a simple wrapper around `Buffer` that adds additional context relevant to files and assets such as their filename, content type, extension, etc. It contains the following data.\n\n```ts\ntype MetaplexFile = Readonly\u003c{\n    buffer: Buffer;\n    fileName: string;\n    displayName: string;\n    uniqueName: string;\n    contentType: string | null;\n    extension: string | null;\n    tags: MetaplexFileTag[];\n}\u003e\n```\n\nYou may use the `toMetaplexFile` function to create a `MetaplexFile` object from a `Buffer` instance (or content `string`) and a filename. The filename is necessary to infer the extension and the mime type of the provided file.\n\n```ts\nconst file = toMetaplexFile('The content of my file', 'my-file.txt');\n```\n\nYou may also explicitly provide these options by passing a third parameter to the constructor.\n\n```ts\nconst file = toMetaplexFile('The content of my file', 'my-file.txt', {\n    displayName = 'A Nice Title For My File'; // Defaults to the filename.\n    uniqueName = 'my-company/files/some-identifier'; // Defaults to a random string.\n    contentType = 'text/plain'; // Infer it from filename by default.\n    extension = 'txt'; // Infer it from filename by default.\n    tags = [{ name: 'my-tag', value: 'some-value' }]; // Defaults to [].\n});\n```\n\nNote that if you want to create a `MetaplexFile` directly from a JSON object, there's a `toMetaplexFileFromJson` helper method that you can use like so.\n\n```ts\nconst file = toMetaplexFileFromJson({ foo: 42 });\n```\n\nIn practice, you will most likely be creating `MetaplexFile`s from files either present on your computer or uploaded by some user on the browser. You can do the former by using `fs.readFileSync`.\n\n```ts\nconst buffer = fs.readFileSync('/path/to/my-file.txt');\nconst file = toMetaplexFile(buffer, 'my-file.txt');\n```\n\nAnd the latter by using the `toMetaplexFileFromBrowser` helper method which accepts a `File` object as defined in the browser.\n\n```ts\nconst browserFile: File = event.target.files[0];\nconst file: MetaplexFile = await toMetaplexFileFromBrowser(browserFile);\n```\n\nOkay, now let’s talk about the concrete storage drivers available to us and how to set them up.\n\n### bundlrStorage\n\nThe `bundlrStorage` driver is the default driver and uploads assets on Arweave using the [Bundlr network](https://bundlr.network/).\n\nBy default, it will use the same RPC endpoint used by the `Metaplex` instance as a `providerUrl` and the mainnet address `\"https://node1.bundlr.network\"` as the Bundlr address.\n\nYou may customise these by passing a parameter object to the `bundlrStorage` method. For instance, here’s how you can use Bundlr on devnet.\n\n```ts\nimport { bundlrStorage } from \"@metaplex-foundation/js\";\n\nmetaplex.use(bundlrStorage({\n    address: 'https://devnet.bundlr.network',\n    providerUrl: 'https://api.devnet.solana.com',\n    timeout: 60000,\n}));\n```\n\nTo fund your bundlr storage account you can cast it in TypeScript like so:\n\n```ts\nconst bundlrStorage = metaplex.storage().driver() as BundlrStorageDriver;\n```\n\nThis gives you access to useful public methods such as:\n\n```ts\nbundlrStorage.fund([metaplexFile1, metaplexFile2]); // Fund using file size.\nbundlrStorage.fund(1000); // Fund using byte size.\n(await bundlrStorage.bundlr()).fund(1000); // Fund using lamports directly.\n```\n\n### mockStorage\n\nThe `mockStorage` driver is a fake driver mostly used for testing purposes. It will not actually upload the assets anywhere but instead will generate random URLs and keep track of their content in a local dictionary. That way, once uploaded, an asset can be retrieved using the `download` method.\n\n```ts\nimport { mockStorage } from \"@metaplex-foundation/js\";\n\nmetaplex.use(mockStorage());\n```\n\n### Additional Storage Drivers\n\nThe following storage drivers are available as separate packages and must be installed separately.\n\n- [`js-plugin-aws`](https://github.com/metaplex-foundation/js/tree/main/packages/js-plugin-aws) Uploads files to AWS.\n- [`js-plugin-nft-storage`](https://github.com/metaplex-foundation/js/tree/main/packages/js-plugin-nft-storage) Uploads files to IPFS via NFT.Storage.\n\n## Programmable NFTs\n\nStarting from version `0.18.0`, you can now create and maintain programmable NFTs via the JS SDK. Here are some quick examples using the latest instructions from Token Metadata which can be used for all token standards (not only programmable NFTs).\n\nNote that managing rulesets is not yet supported on the JS SDK and you will need to use [the Token Auth Rules library](https://github.com/metaplex-foundation/mpl-token-auth-rules/tree/main/packages/sdk) for that purpose.\n\n### Create\n\nCreate all the required accounts of an NFT. Namely, the mint account (if it doesn't already exist), the metadata account and the master edition account. Setting the `tokenStandard` to `ProgrammableNonFungible` in the example below is what makes the created NFT a programmable one. You may also provide a `ruleSet` account at this point.\n\nNote that `createSft` can be used for fungible standards.\n\n```ts\nawait metaplex.nfts().createNft({\n    tokenStandard: TokenStandard.ProgrammableNonFungible,\n    // ...\n});\n```\n\n### Mint\n\nMint new tokens. From 0 to 1 for NFTs or any for SFTs.\n\nThis will create the token account if it doesn't already exist.\n\n```ts\nawait metaplex.nfts().mint({\n    nftOrSft: sft,\n    toOwner,\n    amount: token(1),\n});\n```\n\n### Update\n\nUpdate the metadata and/or master edition accounts of an asset. You may also update the `ruleSet` account for programmable NFTs.\n\n```ts\nawait metaplex.nfts().update({\n    nftOrSft,\n    name: \"My new NFT name\",\n    ruleSet: ruleSet.publicKey,\n});\n```\n\n### Transfer\n\nTransfer an asset fully or partially (for SFTs). For programmable NFTs, it will ensure that the transfer is allowed by the ruleset. For the other token standards, it will delegate the transfer to the SPL token program.\n\n```ts\nawait metaplex.nfts().transfer({\n    nftOrSft,\n    authority: ownerA,\n    fromOwner: ownerA.publicKey,\n    toOwner: ownerB.publicKey,\n    amount: token(1),\n});\n```\n\n### Delegate\n\nApproves a new delegate authority for a given role. There are two types of delegates: metadata delegates and token delegates.\n- Metadata delegates are approved by the update authority of the NFT and each manages one aspect of the metadata account. There can be multiple metadata delegates for the same asset.\n- Token delegates are approved by the owner of an NFT and are used to transfer, lock and/or burn tokens. There can be only one token delegate per token account.\n\nYou can read more about delegates and their roles in the [Programmable NFT Guide](https://github.com/metaplex-foundation/metaplex-program-library/blob/master/token-metadata/program/ProgrammableNFTGuide.md#--delegates).\n\n```ts\n// Metadata delegate.\nawait metaplex.nfts().delegate({\n    nftOrSft,\n    authority: updateAuthority,\n    delegate: {\n        type: 'CollectionV1',\n        delegate: collectionDelegate.publicKey,\n        updateAuthority: updateAuthority.publicKey,\n    },\n});\n\n// Token delegate (for programmable NFTs only).\nawait metaplex.nfts().delegate({\n    nftOrSft,\n    authority: nftOwner,\n    delegate: {\n        type: 'TransferV1',\n        delegate: transferDelegate.publicKey,\n        owner: nftOwner.publicKey,\n        data: { amount: 1 },\n    },\n});\n```\n\n### Revoke\n\nRevoke a delegated authority. Note that only metadata delegates can be self-revoked.\n\n```ts\n// Metadata delegate.\nawait metaplex.nfts().revoke({\n    nftOrSft,\n    authority: updateAuthority,\n    delegate: {\n        type: 'CollectionV1',\n        delegate: collectionDelegate.publicKey,\n        updateAuthority: updateAuthority.publicKey,\n    },\n});\n\n// Token delegate (for programmable NFTs only).\nawait metaplex.nfts().revoke({\n    nftOrSft,\n    authority: nftOwner,\n    delegate: {\n        type: 'TransferV1',\n        delegate: transferDelegate.publicKey,\n        owner: nftOwner.publicKey,\n    },\n});\n\n// Metadata delegate self-revoke.\nawait metaplex.nfts().revoke({\n    nftOrSft,\n    authority: { __kind: 'self', delegate: collectionDelegate },\n    delegate: {\n        type: 'CollectionV1',\n        delegate: collectionDelegate.publicKey,\n        updateAuthority: nft.updateAuthorityAddress,\n    },\n});\n```\n\n### Lock/Unlock\n\nAllow specific delegates to lock and unlock programmable NFTs. This is for programmable NFTs only.\n\n```ts\n// Lock an NFT using a utility delegate.\nawait metaplex.nfts().lock({\n    nftOrSft: nft,\n    authority: {\n        __kind: 'tokenDelegate',\n        type: 'UtilityV1',\n        delegate: utilityDelegate,\n        owner: nftOwner.publicKey,\n    },\n});\n\n// Unlock an NFT using a utility delegate.\nawait metaplex.nfts().unlock({\n    nftOrSft: nft,\n    authority: {\n        __kind: 'tokenDelegate',\n        type: 'UtilityV1',\n        delegate: utilityDelegate,\n        owner: nftOwner.publicKey,\n    },\n});\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmetaplex-foundation%2Fjs","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmetaplex-foundation%2Fjs","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmetaplex-foundation%2Fjs/lists"}
