Starter App

Files structure

- src
 -- services
  --- FetchPageLinks.js
 -- components
 -- tests
  --- index.js
  --- FetchPageLinks.js

Put your services into the src/services folder. They will be accessible from within webmiddle-devtools. Their props, context options and return value should all be JSON-serializable since will be transferred over the network.

Put your other components into src/components.

Organize your tests info multiple files and folders into src/tests.

Testing

Remember to export the tests with index.js files or they won't be accessible from within webmiddle-devtools.

By default tests use AVA, which means they will be executed in parallel and can be written with modern JavaScript, since they are transpiled with Babel.

Every test you define also creates a Service that can be used within webmiddle-devtools to debug the test. This is done by using test-wrapper.js. If you would like to use another testing library, then you should create an appropriate test-wrapper.js file.

Ckeck out src/tests/FetchPageLinks for an example.

Debugging

Start the webmiddle-server together with webmiddle-devtools and rebuild automatically on changes with

yarn start:devtools

To change the ports of webmiddle-server and webmiddle-devtools, set the PORT env variable in package.json scripts server and devtools, respectively.

In the evaluation tab, you can also put the description of a test to search for it.

Make sure to set the debug context option to true, otherwise you won't be able to inspect the evaluation call tree.

Specify further props and context.options and then press Evaluate.
