💻 Develop

Set up

Check you have the correct version of Node. You can install NVM to switch between node versions. Then NVM install. Before you build you will need to yarn install in the root directory. The repository includes a number of template .env files for different networks. Copy from these to the .env file before serve to launch app with different network. You can serve any application with yarn nx run <name-of-app>:serve.

Build

Run nx build my-app to build the project. The build artifacts will be stored in the dist/ directory. Use the --prod flag for a production build.

Run nx serve my-app for a dev server. Navigate to the port specified in app/<project-name>/project.json. The app will automatically reload if you change any of the source files.

Running tests

Run yarn nx run <my-app>-e2e:e2e to execute the e2e tests with cypress, or nx affected:e2e will execute just the end-to-end tests affected by a change. You can use the --watch flag to open the cypress tests UI in watch mode, see cypress executor for all CLI flags.

Run nx test my-app to execute the unit tests with Jest, or nx affected:test to execute just unit tests affected by a change. You can also use --watch with these test to run jest in watch mode, see Jest executor for all CLI flags.

Formatting
