Mirage-MSW

Experimental MirageJS interceptor using MSW.

Usage

Installation

Pick one depending on your package manager:

npm i --save-dev mirage-msw
pnpm i --save-dev mirage-msw
yarn add --dev mirage-msw

If you are not already using MSW or Mirage, you will need to install those as well. Be sure to run msw init as well.

We currently only support MSW v1, though we are exploring v2 support: miragejs#12

Configuration

Wherever you are creating your miragejs server, set the interceptor:

import MSWInterceptor from 'mirage-msw';
import { createServer } from 'miragejs';

createServer({
  interceptor: new MSWInterceptor(),
  // ... rest of your config
});

This will cause msw to be used instead of the default interceptor, pretender.

Caveats

This is very early, experimental software. There are probably a lot of bugs, so if you find one, please report it.

Here are the known issues so far:

• MSW starts up asynchronously, whereas Mirage up to now has always been completely synchronous. We will probably need to make a breaking change to Mirage to make createServer an async function.
• Currently no support for FormData requests.
• Only works in the browser, same as pretender. But MSW does have an option for node.js, so we may be able to support that in the future.
