It is also not possible to manage from nodejs.\nAnvild solves all these problems:\n\n- does not require local installation of Anvil\n- easy to use interface from Nodejs\n- good type support\n\n\u003chr\u003e\n\u003cbr\u003e\n\u003cp align=\"center\"\u003e\n  \u003ca aria-label=\"NPM version\" href=\"https://www.npmjs.com/package/anvild\"\u003e\n    \u003cimg alt=\"\" src=\"https://img.shields.io/npm/v/anvild.svg?style=for-the-badge\u0026labelColor=000000\"\u003e\n  \u003c/a\u003e\n  \u003ca aria-label=\"License\" href=\"https://github.com/eddort/anvild/blob/main/license.md\"\u003e\n    \u003cimg alt=\"\" src=\"https://img.shields.io/npm/l/anvild.svg?style=for-the-badge\u0026labelColor=000000\"\u003e\n  \u003c/a\u003e\n\u003c/p\u003e\n\n## Installation\n\nTo install Anvil Docker Manager, follow these steps:\n\n1. Ensure you have Node.js and Docker installed.\n\n2. Install `anvild` using npm/yarn/pnpm\n\n```bash\nyarn add anvild\n```\n\n3. Create Anvil node using Nodejs\n\n```ts\nimport { cleanAll, createAnvil } from \"anvild\";\n\n(async () =\u003e {\n  // clean all Anvil instances\n  await cleanAll();\n  // run anvil node with default config\n  const node = await createAnvil({});\n})();\n```\n\n## Alternatives\n- https://github.com/wagmi-dev/anvil.js — nodejs wrapper for Anvil. Depends on local Anvil installation.\n\n## Api reference\n\n### Anvil Options\n\n##### computeUnitsPerSecond (Optional)\n\n- Type: `number`\n- Default: `350`\n- Description: Sets the number of assumed available compute units per second for this fork provider.\n\n#### forkUrl (Optional)\n\n- Type: `string`\n- Description: Fetch state over a remote endpoint instead of starting from an empty state. If you want to fetch state from a specific block number, add a block number like `http://localhost:8545@1400000` or use the `forkBlockNumber` option.\n\n#### forkBlockNumber (Optional)\n\n- Type: `number` or `bigint`\n- Description: Fetch state from a specific block number over a remote endpoint. Requires `forkUrl` to be set.\n\n#### forkChainId (Optional)\n\n- Type: `number`\n- Description: Specify chain id to skip fetching it from the remote endpoint. This enables offline-start mode. You still must pass both `forkUrl` and `forkBlockNumber`, and already have your required state cached on disk, anything missing locally would be fetched from the remote.\n\n#### forkRetryBackoff (Optional)\n\n- Type: `number`\n- Description: Initial retry backoff on encountering errors.\n\n#### noRateLimit (Optional)\n\n- Type: `boolean`\n- Default: `false`\n- Description: Disables rate limiting for this node's provider. See [here](https://github.com/alchemyplatform/alchemy-docs/blob/master/documentation/compute-units.md#rate-limits-cups).\n\n#### noStorageCaching (Optional)\n\n- Type: `boolean`\n- Description: Explicitly disables the use of RPC caching. All storage slots are read entirely from the endpoint.\n\n#### retries (Optional)\n\n- Type: `number`\n- Default: `5`\n- Description: Number of retry requests for spurious networks (timed out requests).\n\n#### timeout (Optional)\n\n- Type: `number`\n- Default: `45000`\n- Description: Timeout in ms for requests sent to remote JSON-RPC server in forking mode.\n\n#### blockBaseFeePerGas (Optional)\n\n- Type: `bigint`\n- Description: The base fee in a block.\n\n#### chainId (Optional)\n\n- Type: `number`\n- Description: The chain id.\n\n#### codeSizeLimit (Optional)\n\n- Type: `number`\n- Default: `0x6000` (~25kb)\n- Description: EIP-170: Contract code size limit in bytes. Useful to increase this because of tests.\n\n#### disableBlockGasLimit (Optional)\n\n- Type: `boolean`\n- Description: Disable the `call.gas_limit \u003c= block.gas_limit` constraint.\n\n#### gasLimit (Optional)\n\n- Type: `bigint`\n- Description: The block gas limit.\n\n#### gasPrice (Optional)\n\n- Type: `bigint`\n- Description: The gas price.\n\n#### accounts (Optional)\n\n- Type: `number`\n- Default: `10`\n- Description: Number of dev accounts to generate and configure.\n\n#### balance (Optional)\n\n- Type: `bigint`\n- Default: `10000`\n- Description: The balance of every dev account in Ether.\n\n#### derivationPath (Optional)\n\n- Type: `string`\n- Default: `m/44'/60'/0'/0/`\n- Description: Sets the derivation path of the child key to be derived.\n\n#### mnemonic (Optional)\n\n- Type: `string`\n- Description: BIP39 mnemonic phrase used for generating accounts.\n\n#### port (Optional)\n\n- Type: `number`\n- Default: `8545`\n- Description: Port number to listen on.\n\n#### stepsTracing (Optional)\n\n- Type: `boolean`\n- Description: Enable steps tracing used for debug calls returning geth-style traces.\n\n#### timestamp (Optional)\n\n- Type: `bigint`\n- Description: The timestamp of the genesis block.\n\n#### allowOrigin (Optional)\n\n- Type: `string`\n- Default: `*`\n- Description: Set the Access-Control-Allow-Origin response header (CORS).\n\n#### blockTime (Optional)\n\n- Type: `number`\n- Description: Block time in seconds for interval mining.\n\n#### configOut (Optional)\n\n- Type: `string`\n- Description: Writes output of `anvil` as JSON to user-specified file.\n\n#### dumpState (Optional)\n\n- Type: `string`\n- Description: Dump the state of the chain on exit to the given file. If the value is a directory, the state will be written to `\u003cVALUE\u003e/state.json`.\n\n#### hardfork (Optional)\n\n- Type: `enum` (`chainstart`, `berlin`, `london`)\n- Description: The EVM hardfork to use.\n\n#### host (Optional)\n\n- Type: `string`\n- Default: `0.0.0.0`\n- Description: The host the server will listen on.\n\n#### init (Optional)\n\n- Type: `string`\n- Description: Initialize the genesis block with the given `genesis.json` file.\n\n#### ipc (Optional)\n\n- Type: `string`\n- Description: Launch an IPC server at the given path or default path = `/tmp/anvil.ipc`.\n\n#### loadState (Optional)\n\n- Type: `string`\n- Description: Initialize the chain from a previously saved state snapshot.\n\n#### noCors (Optional)\n\n- Type: `boolean`\n- Description: Disable CORS.\n\n#### noMining (Optional)\n\n- Type: `boolean`\n- Description: Disable auto and interval mining, and mine on demand instead.\n\n#### order (Optional)\n\n- Type: `string`\n- Default: `fees`\n- Description: How transactions are sorted in the mempool.\n\n#### pruneHistory (Optional)\n\n- Type: `number` or `boolean`\n- Description: Don't keep full chain history.\n\n#### stateInterval (Optional)\n\n- Type: `number`\n- Description: Interval in seconds at which the status is to be dumped to disk.\n\n#### silent (Optional)\n\n- Type: `boolean`\n- Description: Don't print anything on startup and don't print logs.\n\n#### state (Optional)\n\n- Type: `string`\n- Description: This is an alias for both `loadState` and `dumpState`.\n\n#### transactionBlockKeeper (Optional)\n\n- Type: `number`\n- Description: Number of blocks with transactions to keep in memory.\n\n## Instance Options\n\n#### socketPath (Optional)\n\n- Type: `string`\n- Description: Docker socket path.\n\n#### attachLogs (Optional)\n\n- Type: `boolean`\n- Default: `true`\n- Description: Attach Anvil logs to the current process.\n\n#### forceRecreate (Optional)\n\n- Type: `boolean`\n- Default: `true`\n- Description: Force re-create the instance with the same configuration.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Feddort%2Fanvild","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Feddort%2Fanvild","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Feddort%2Fanvild/lists"}
