Implementation of the Happy or Sad App using React, Redux and Express.
As suggested, Dan Abramov's react-hot-boilerplate v2 is used as a starting point (includes webpack config and a dev express server).
The dependencies have been updated since this project is not maintained any more.
You need Node v6 as minimum to run this project (ES6 features are used without transpilation in the API server). Ideally use Yarn so that you get locked dependencies.
To run the project, make sure all the dependencies are installed using npm install or yarn install. Then run npm start or yarnpkg start.
To run the project in livereload mode use npm run dev or yarnpkg run dev.
To run the tests use npm test or yarn test. If you would like more verbose output use npm test -- --verbose or yarn test -- --verbose.
You can use AVA (test runner) in watch mode by passing it the -w flag (which gives npm test -- -w or yarn test -- -w).
In the src directory you will find the api and client directories. They contain the API app to rate whether text is happy or sad and the React frontend app respectively.
The tests are colocated with the application code and are named fileContainingCodeBeingTested.test.js following the AVA default blob (**/*.test.js).
Redux is used to managed state in the React app. Although it would have been possible to do everything through component state (and setState),
using Redux allows us to test the React components more easily (since we leverage props).
As an HTTP client, we use axios which is a promise-based client that works both with Node and in the browser.
On the backend, we use a simple Express API server that has a single POST rateMood endpoint.
It is served as a separate HTTP server and therefore has CORS enabled.
For testing we use AVA, for its low config and watch system and Enzyme to test React components. We use sinon for function stubbing.
In terms of development environment, we leverage node-dev to livereload the API server (and webpack dev server) when code changes.
