The js-ipfs's intro from mehrdad-shokri

Upgrading from <=0.40 to 0.48? See the release notes for the list of API changes and the migration guide.

We've come a long way, but this project is still in Alpha, lots of development is happening, APIs might change, beware of 🐉..

Getting started

Look into the examples to learn how to spawn an IPFS node in Node.js and in the Browser
Read the Core API docs to see what you can do with an IPFS node
Visit https://dweb-primer.ipfs.io to learn about IPFS and the concepts that underpin it
Head over to https://proto.school to take interactive tutorials that cover core IPFS APIs
Check out https://docs.ipfs.io for tips, how-tos and more

This project is broken into several modules, their purposes are:

/packages/ipfs The core implementation
/packages/ipfs-http-client A client for the RPC-over-HTTP API presented by both js-ipfs and go-ipfs
/packages/interface-ipfs-core Tests to ensure adherence of an implementation to the spec
/packages/ipfs-core-utils Helpers and utilities common to core and the HTTP RPC API client

The IPFS implementation in JavaScript needs your help! There are a few things you can do right now to help out:

Check out existing issues The issue list has many that are marked as 'help wanted' or 'difficulty:easy' which make great starting points for development, many of which can be tackled with no prior IPFS knowledge
Look at the IPFS Roadmap This are the high priority items being worked on right now
Perform code reviews More eyes will help a. speed the project along b. ensure quality, and c. reduce possible future bugs.
Add tests. There can never be enough tests.
Join the Weekly Core Implementations Call it's where everyone discusses what's going on with IPFS and what's next
