  • Example of using unmock in running on-device in React Native. In development, where NODE_ENV==="development", switches on Unmock to mock the Cat Facts API.
  • Uses unmock from unmock-browser: this seems to be a safer bet than using unmock package, because using that seems to mess things up when running a development server. unmock-browser only overrides global.fetch or window.fetch and cannot have weird sife-effects of messing up other Node.js stuff (might be worth checking if this can be fixed by adding react-native field in the package.json of unmock

Tricks this required:

  • global.Buffer needs to be poly-filled with require('buffer').Buffer: facebook/react-native#23922 (comment) Implemented in unmock/unmock-js#359
  • json-schema-ref-parser depends on http, https and url so metro bundler fails building the project because http, https and url cannot be resolved. The manual fix is to edit node_modules/json-schema-ref-parser/package.json and add http: false and https: false in its browser field (apparently the modules are not needed by unmock-core). The problem with url can be similarly by adding url: false or, preferably, "url": "whatwg-url" Implemented in unmock/unmock-js#360

Future stuff:

  • Running tests in the virtual device using Unmock?
  • Adding a component for switching Unmock on and off?
  • Adding CircleCI integration
