This project demonstrates my changes starting from Create React App to get to a more production worthy app.

I also updated the initial app to be based off of an article by DefinedByChoice that makes an API call for Star Wars characters and lists the characters. This change introduces a real world API call for populating the store, something closer to a real-world business app.

Goals

• Add testing, test coverage reporting, and approach 100% test coverage.
• Use a scalable file structure, centered around feature/domain.
• Maintain small files and classes.
• Leverage TypeScript's type system as much as possible.

Added Patterns and Tools

Code organization

• Thunk: write action creators that return functions.
• Organize files around feature/domain

Testing

• Added airbnb's Enzyme for component testing
• Added test coverage ($ yarn test:coverage) using the Facebook docs
• Added test fixture for returned characters inside getCharactersMock.ts
• I tried both container testing approaches here, and preferred the one that doesn't require connect. here

Available Scripts

In the project directory, you can run:

yarn start

Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console.

yarn test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

yarn test:coverage

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

yarn run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

See the section about deployment for more information.

yarn run eject

Note: this is a one-way operation. Once you eject, you can’t go back!

If you aren’t satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project.

Instead, it will copy all the configuration files and the transitive dependencies (Webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.

You don’t have to ever use eject. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
