# Monero TypeScript Library



A TypeScript library for creating Monero applications using RPC and WebAssembly bindings to [monero v0.18.3.3 'Fluorine Fermi'](https://github.com/monero-project/monero/tree/v0.18.3.3).



* Supports client-side wallets in Node.js and the browser using WebAssembly.

* Supports wallet and daemon RPC clients.

* Supports multisig, view-only, and offline wallets.

* Wallet types are interchangeable by conforming to a [common interface](https://woodser.github.io/monero-ts/typedocs/classes/MoneroWallet.html).

* Uses a clearly defined [data model and API specification](https://woodser.github.io/monero-java/monero-spec.pdf) intended to be intuitive and robust.

* [Query wallet transactions, transfers, and outputs](docs/developer_guide/query_data_model.md) by their properties.

* Fetch and process binary data from the daemon (e.g. raw blocks).

* Receive notifications when blocks are added to the chain or when wallets sync, send, or receive.

* Over 300 passing Mocha tests.



## Architecture





	


	Build browser or Node.js applications using RPC or WebAssembly bindings to monero-project/monero.  Wallet implementations are interchangeable by conforming to a common interface, MoneroWallet.ts.




## Sample code



```typescript

// import monero-ts (or import types individually)

import moneroTs from "monero-ts";



// connect to daemon

let daemon = await moneroTs.connectToDaemonRpc("http://localhost:28081");

let height = await daemon.getHeight();        // 1523651

let txsInPool = await daemon.getTxPool();     // get transactions in the pool



// create wallet from mnemonic phrase using WebAssembly bindings to monero-project

let walletFull = await moneroTs.createWalletFull({

  path: "sample_wallet_full"

  password: "supersecretpassword123",

  networkType: moneroTs.MoneroNetworkType.TESTNET,

  seed: "hefty value scenic...",

  restoreHeight: 573936,

  server: { // provide url or MoneroRpcConnection

    uri: "http://localhost:28081",

    username: "superuser",

    password: "abctesting123"

  }

});



// synchronize with progress notifications

await walletFull.sync(new class extends moneroTs.MoneroWalletListener {

  async onSyncProgress(height: number, startHeight: number, endHeight: number, percentDone: number, message: string) {

    // feed a progress bar?

  }

} as moneroTs.MoneroWalletListener);



// synchronize in the background every 5 seconds

await walletFull.startSyncing(5000);



// receive notifications when funds are received, confirmed, and unlocked

let fundsReceived = false;

await walletFull.addListener(new class extends moneroTs.MoneroWalletListener {

  async onOutputReceived(output: moneroTs.MoneroOutputWallet) {

    let amount = output.getAmount();

    let txHash = output.getTx().getHash();

    let isConfirmed = output.getTx().getIsConfirmed();

    let isLocked = output.getTx().getIsLocked();

    fundsReceived = true;

  }

});



// connect to wallet RPC and open wallet

let walletRpc = await moneroTs.connectToWalletRpc("http://localhost:28084", "rpc_user", "abc123");

await walletRpc.openWallet("sample_wallet_rpc", "supersecretpassword123");

let primaryAddress = await walletRpc.getPrimaryAddress(); // 555zgduFhmKd2o8rPUz...

let balance = await walletRpc.getBalance();   // 533648366742

let txs = await walletRpc.getTxs();           // get transactions containing transfers to/from the wallet



// send funds from RPC wallet to WebAssembly wallet

let createdTx = await walletRpc.createTx({

  accountIndex: 0,

  address: await walletFull.getAddress(1, 0),

  amount: 250000000000n, // send 0.25 XMR (denominated in atomic units)

  relay: false // create transaction and relay to the network if true

});

let fee = createdTx.getFee(); // "Are you sure you want to send... ?"

await walletRpc.relayTx(createdTx); // relay the transaction



// recipient receives unconfirmed funds within 5 seconds

await new Promise(function(resolve) { setTimeout(resolve, 5000); });

assert(fundsReceived);



// save and close WebAssembly wallet

await walletFull.close(true);

```

## Using monero-ts in your project



1. `cd your_project` or `mkdir your_project && cd your_project && npm init`

2. `npm install monero-ts`

3. Add `import moneroTs from "monero-ts"` in your application code (or import types individually).



#### Running in Node.js



Node 20 LTS is recommended. Alternatively, Node 16 and 18 LTS work using the `--experimental-wasm-threads` flag.



To avoid the error "Failed to parse URL from /path/to/file.wasm" on Node.js >16:



1. Pass the `--no-experimental-fetch` flag to `node`.

2. Set OpenSSL legacy provider:

    - Unix: `export NODE_OPTIONS=--openssl-legacy-provider`

    - Windows: `set NODE_OPTIONS=--openssl-legacy-provider`



#### Building a browser application

1. Bundle your application code for a browser. See [xmr-sample-app](https://github.com/woodser/xmr-sample-app) for an example project using webpack.

2. Copy assets from ./dist to your web app's build directory.



#### Using RPC servers:

1. Download and install [Monero CLI](https://web.getmonero.org/downloads/).

2. Start monerod, e.g.: `./monerod --stagenet` (or use a remote daemon).

3. Start monero-wallet-rpc, e.g.: `./monero-wallet-rpc --daemon-address http://localhost:38081 --stagenet --rpc-bind-port 38084 --rpc-login rpc_user:abc123 --wallet-dir ./`



## Building WebAssembly binaries from source



This project uses WebAssembly to package and execute Monero's source code for a browser or other WebAssembly-supported environment.



Compiled WebAssembly binaries are committed to ./dist for convenience, but these files can be built independently from source code:



1. Install and activate emscripten.

	1. Clone emscripten repository: `git clone https://github.com/emscripten-core/emsdk.git`

	2. `cd emsdk`

	3. `git pull && ./emsdk install 3.1.10 && ./emsdk activate 3.1.10 && source ./emsdk_env.sh`

	4. `export EMSCRIPTEN=path/to/emsdk/upstream/emscripten` (change for your system)

2. Clone monero-ts repository: `git clone --recursive https://github.com/woodser/monero-ts.git`

3. `cd monero-ts`

4. `./bin/update_submodules.sh`

5. Modify ./external/monero-cpp/external/monero-project/src/crypto/wallet/CMakeLists.txt from `set(MONERO_WALLET_CRYPTO_LIBRARY "auto" ...` to `set(MONERO_WALLET_CRYPTO_LIBRARY "cn" ...`.

6. Build the monero-cpp submodule (located at ./external/monero-cpp) by following [instructions](https://github.com/woodser/monero-cpp#using-monero-cpp-in-your-project) for your system. This will ensure all dependencies are installed. Be sure to install unbound 1.19.0 to your home directory (`~/unbound-1.19.0`).

7. `./bin/build_all.sh` (install [monero-project dependencies](https://github.com/monero-project/monero#dependencies) as needed for your system)



## Running tests



1. Clone the project repository: `git clone https://github.com/woodser/monero-ts.git`

2. `cd monero-ts`

3. Start RPC servers:

	1. Download and install [Monero CLI](https://web.getmonero.org/downloads/).

	2. Start monerod, e.g.: `./monerod --testnet` (or use a remote daemon).

	3. Start monero-wallet-rpc, e.g.: `./monero-wallet-rpc --daemon-address http://localhost:38081 --testnet --rpc-bind-port 28084 --rpc-login rpc_user:abc123 --wallet-dir ./`

4. Configure the appropriate RPC endpoints, authentication, and other settings in [TestUtils.ts](src/test/utils/TestUtils.ts) (e.g. `WALLET_RPC_CONFIG` and `DAEMON_RPC_CONFIG`).



#### Running tests in Node.js



* Run all tests: `npm test`

* Run tests by their description, e.g.: `npm run test -- --grep "Can get transactions"`



#### Running tests in a browser



1. Start monero-wallet-rpc servers used by tests: `./bin/start_wallet_rpc_test_servers.sh`

2. In another terminal, build browser tests: `./bin/build_browser_tests.sh`

3. Access http://localhost:8080/tests.html in a browser to run all tests
