Solana JavaScript API

This is the Solana Javascript API built on the Solana JSON RPC API

Latest API Documentation

Installation

Yarn

$ yarn add @solana/web3.js

npm

$ npm install --save @solana/web3.js

Browser bundle

<script src="https://github.com/solana-labs/solana-web3.js/releases/download/v0.0.6/solanaWeb3.min.js"></script>

BPF program development

The Solana BPF SDK is located in the bpf-sdk/ subdirectory if you installed solana-web3.js from npmjs.com.

From a git clone, run npm run bpf-sdk:install to fetch the latest BPF SDK.

Additionally Rust must be installed to build Rust BPF programs such as examples/bpf-rust-noop/. See https://www.rust-lang.org/install.html for installation details.

Usage

Javascript

const solanaWeb3 = require('@solana/web3.js');
console.log(solanaWeb3);

ES6

import solanaWeb3 from '@solana/web3.js';
console.log(solanaWeb3);

Browser bundle

// `solanaWeb3` is provided in the global namespace by the `solanaWeb3.min.js` script bundle.
console.log(solanaWeb3);

Local Network

The solana-localnet program is provided to easily start a test Solana cluster locally on your machine. Docker must be installed. The JSON RPC endpoint of the local cluster is http://localhost:8899.

To start, first fetch the latest Docker image by running:

$ npx solana-localnet update

Then run the following command to start the cluster

$ npx solana-localnet up

While the cluster is running logs are available with:

$ npx solana-localnet logs -f

Stop the cluster with:

$ npx solana-localnet down

Flow

A Flow library definition is provided at module.flow.js. Add the following line under the [libs] section of your project's .flowconfig to activate it:

[libs]
node_modules/@solana/web3.js/module.flow.js

Examples

See the examples/ directory for small snippets.

Standalone examples:

Releases

Releases are available on Github and npmjs.com

Each Github release features a tarball containing API documentation and a minified version of the module suitable for direct use in a browser environment (<script> tag)
