# ember-service-worker-request-chaos

Often our applications talk to external APIs. Sometimes our apps talk to

external APIs that ~~suck~~ are unreliable. Often, we don't test the failure

cases well enough (or at all).

* What does it look like when a request to X service flakes out?

* Where could we add recovery options?

We can answer these questions with **Service Workers** and not have to spend time

setting up a proxy on our local machines to [MITM]() all of our traffic. This addon

adds a service worker via `ember-service-worker` to intercept specified requests

and will randomly return error responses in the `5xx` range.

Find out how well your application tolerates failure!

## Runtime dependencies

  ```

  /* eslint-env node */

  'use strict';

  const EmberAddon = require('ember-cli/lib/broccoli/ember-addon');

  module.exports = function(defaults) {

    let app = new EmberApp(defaults, {

      'esw-request-chaos': {

        // RegExp patterns specifying which URLs to wreck chaos.

        patterns: [

          'https://scaling.is.difficult/api/(.+)',

        ]

      }

    });
