js-algorand-sdk

AlgoSDK is a javascript library for communicating with the Algorand network for modern browsers and node.js.

Installation

node.js

$ npm install algosdk

Browser

The dist directory contains a minified version of the library - algosdk.min.js. Include this line in your HTML.

<script src="algosdk.min.js" />

Quick Start

const token = 'Your algod API token';
const server = 'http://127.0.0.1';
const port = 8080;
const client = new algosdk.Algod(token, server, port);

(async () => {
  console.log(await client.status());
})().catch((e) => {
  console.log(e);
});

Documentation

Examples

Running examples requires access to a running node. Follow the instructions in Algorand's developer resources to install a node on your computer.

As portions of the codebase are written in TypeScript, example files cannot be run directly using node. Please refer to the instructions described in the examples/README.md file for more information regarding running the examples.

SDK Development

Building

To build a new version of the library, run:

npm run build

The dist directory has been removed from version control in releases after v1.8.1. Browser bundles for previous versions can be found by going to that version's tag and looking in the dist folder.

Testing

We have two test suites: mocha tests in this repo, and the Algorand SDK test suite from https://github.com/algorand/algorand-sdk-testing.

Node

To run the mocha tests in Node, run:

npm test

To run the SDK test suite in Node, run:

make docker-test

Browsers

The test suites can also run in browsers. To do so, set the environment variable TEST_BROWSER to one of our supported browsers. Currently we support testing in chrome and firefox. When TEST_BROWSER is set, the mocha and SDK test suites will run in that browser.

For example, to run mocha tests in Chrome:

TEST_BROWSER=chrome npm test

And to run SDK tests in Firefox:

TEST_BROWSER=firefox make docker-test

Code Style

This project enforces a modified version of the Airbnb code style.

We've setup linters and formatters to help catch errors and improve the development experience:

Prettier – ensures that code is formatted in a readable way.
ESLint — checks code for antipatterns as well as formatting.

If using the Visual Studio Code editor with the recommended extensions, ESLint errors should be highlighted in red and the Prettier extension should format code on every save.

Precommit Hook

The linters and formatters listed above should run automatically on each commit to catch errors early and save CI running time.
