## Deprecation Notice

Automerge now has a shiny new implementation at https://github.com/automerge/automerge. This repository is the original pure javascript implementation. All development effort has shifted to the new implementation which is written in Rust and so can easily be ported to other platforms.

Automerge is a library of data structures for building collaborative applications in JavaScript.

Please see [automerge.org](http://automerge.org/) for documentation.

For a set of extensible examples in TypeScript, see [automerge-repo](https://github.com/automerge/automerge-repo)

## Setup

If you're using npm, `npm install automerge`. If you're using yarn, `yarn add automerge`. Then you
can import it with `require('automerge')` as in [the example below](#usage) (or
`import * as Automerge from 'automerge'` if using ES2015 or TypeScript).

Otherwise, clone this repository, and then you can use the following commands:

- `yarn install` — installs dependencies.
- `yarn test` — runs the test suite in Node.
- `yarn run browsertest` — runs the test suite in web browsers.
- `yarn build` — creates a bundled JS file `dist/automerge.js` for web browsers. It includes the
  dependencies and is set up so that you can load through a script tag.
