AlgoSDK is the official JavaScript library for interfacing with the Algorand network, compatible with modern browsers and Node.js. The recently released v3 introduces breaking changes from v2, necessitating codebase adjustments per the available migration guide. Installation can be achieved via npm for Node.js or by incorporating a minified script for browser use. The library includes TypeScript support, requiring version 4.2 or higher. Comprehensive documentation is hosted on the official Algorand website, alongside a suite of developer resources and example files. The library is maintained under a modified Airbnb code style, with Prettier and ESLint ensuring code quality. Pre-commit hooks run these tools automatically to streamline development. Licensed under MIT, AlgoSDK facilitates robust, efficient communication with Algorand, backed by extensive testing across Node.js and browser environments.
