Canvas Rich Content Editor

> The Canvas LMS Rich Content Editor (RCE) extracted in it's own npm package for use across multiple services

In the Canvas ecosystem, this npm module is used in conjunction with the Rich Content Service (RCS) microservice. The code for the RCS is also open source and lives in the canvas-rce-api repository. (see https://github.com/instructure/canvas-rce-api)

Some features require a running instance of the canvas-rce-api, but you do not need an instance in order to do development on @instructure/canvas-rce. (see the Development section)

The primary consumer of the @instructure/canvas-rce is canvas-lms, so documentation
and references throughout documentation might reflect and assume the use of canvas-lms.

Install and Setup

As a published npm module, you can add @instructure/canvas-rce to your node project by doing
the following:

``bash
npm install @instructure/canvas-rce --save
`

For guidance on how @instructure/canvas-rce is used within Canvas, please reference
the canvas-lms use of canvas-rce to get an idea on how to incorporate it into your project. Pay
special attention to the RichContentEditor.js and serviceRCELoader.js.

Outside of Canvas, the CanvasRce React component is your entry point.

Tests

First, build assets. Then you can run the tests:

`bash
yarn build:all
yarn test:jest
`

$3

`
yarn test:jest:debug path/to/__test__/file.test.js
`

will break and wait for you to attach a debugger (e.g. chrome://inspect/#devices).

Both those commands may include a --watch argument to keep the process alive
while you iterate.

Polyfills

This project makes use of modern JavaScript APIs like Promise, Object.assign,
Array.prototype.includes, etc. which are present in modern
browsers but may not be present in old browsers like IE 11. In order to not
send unnecessarily large and duplicated code bundles to the browser, consumers
are expected to have already globally polyfilled those APIs.
Canvas only supports modern browsers and the RCE has not been tested
in older browsers like IE. If you need suggestions for how to include
polyfills in your own app, you can put this in your html above the script that includes
@instructure/canvas-rce:
