Mirage-MSW

Experimental MirageJS interceptor using MSW.

Usage

Installation

Pick one depending on your package manager. Mirage 0.2.0-alpha.3+ and MSW 2.0.0+ are peer dependencies.

npm i --save-dev mirage-msw miragejs@^0.2.0-alpha.3 msw@^2
pnpm i --save-dev mirage-msw miragejs@^0.2.0-alpha.3 msw@^2
yarn add --dev mirage-msw miragejs@^0.2.0-alpha.3 msw@^2

Be sure to run msw init as well, if you haven't previously.

Configuration

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

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

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

// Important to wait for msw to start up before rendering your app
await server.start();

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. (Added in mirage 0.2.0-alpha.1)
• 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. (#17)
