The IOTA Pico Framework library is an alternative to the official iota.lib.js

The library is a bundle of all the following components:

• @iota-pico/core - Core functions and helper classes.
• @iota-pico/data - Data objects.
• @iota-pico/api - REST API.
• @iota-pico/crypto - Crypto functions Curl/Kerl/SHA3.
• @iota-pico/business - Business layer to perform transactions.
• @iota-pico/pal-browser - Platform abstraction layer for the browser.
• @iota-pico/pow-box - Proof of Work using TestNet PowBox. (for TestNet)
• @iota-pico/pow-js - Proof of Work using JavaScript. (Very Slow - Single Threaded)
• @iota-pico/pow-srvio - Proof of Work using Remote powsrv.io web site api.
• @iota-pico/pow-wasm - Proof of Work using WebAssembly. (Slow - Single-Threaded)
• @iota-pico/pow-webgl - Proof of Work using WebGL. (Best Choice - Multi-Threaded)

If you want to run on NodeJS try the alternate version @iota-pico/lib-nodejs

npm install @iota-pico/lib-browser --save

The library also has a dependency of big-integer which should get installed with the main package.

There are two variants of the library

• development - which is not minified and includes source maps in pkg/iota-pico-lib-browser.js
• production - which is minified and has no source maps in pkg/iota-pico-lib-browser.min.js

If you don't want all of the proof of work algorithms, there are some alternative smaller packages:

• pkg/iota-pico-lib-browser-none.js - No Proof Of Work algorithms
• pkg/iota-pico-lib-browser-none.min.js - No Proof Of Work algorithms
• pkg/iota-pico-lib-browser-webgl.js - Fastest for Platform
• pkg/iota-pico-lib-browser-webgl.min.js - Fastest for Platform

TypeScript definitions can be found in the pkg/iota-pico-lib-browser.d.ts and should be located automatically by your developments tools.

The library is compiled into a UMD that can be included directly in the browser or by using a module loader (Browserify/RequireJS/SystemJS/Webpack). You can see various usage scenarios in the following browser tutorials:

• Usage Library Script Include
• Usage Library Browserify
• Usage Library RequireJS
• Usage Library SystemJS
• Usage Library Webpack

The documentation for each part of the library can be found in it's relevant repository:

• @iota-pico/core documentation
• @iota-pico/data documentation
• @iota-pico/api documentation
• @iota-pico/crypto documentation
• @iota-pico/business documentation
