codecrafters-frontend

The front-end app that powers app.codecrafters.io.

Prerequisites

You will need the following things installed on your computer:

• Git
• Node.js (with npm)
• Ember CLI
• Google Chrome

You can run tests locally without a backend server, but to use the app you'll also need an instance of codecrafters-io/core running. You can either run this against staging, or against a local instance of core. Visit the core repo for setup instructions.

Setup / Installation

• git clone <repository-url> this repository
• cd frontend
• npm install
• Copy .env.example to .env and fill in the values

Running / Development

• make serve
• Visit your app at https://.ccdev.dev.
• Visit your app at http://localhost:4200.
• Visit your tests at http://localhost:4200/tests.

Running against staging

• Run BACKEND_URL="https://backend-staging.codecrafters.io" npm run start
• View your app at http://localhost:4200

Running with or without FastBoot

• FastBoot is enabled when running ember build --environment=production
  • Pre-rendering is done only for routes configured under prember section in ember-cli-build.js
• FastBoot is enabled for all routes when running ember server
  • To disable it, run FASTBOOT_DISABLED=true ember server
  • Alternatively, append ?fastboot=false query parameter to each request URL
• Add FASTBOOT_DISABLED=true to your local .env file to disable FastBoot completely
  • You can override it by passing FASTBOOT_DISABLED="" in the command line
• NPM tasks start and start:ember run with FastBoot disabled
• NPM tasks start:fastboot and start:ember:fastboot run with FastBoot enabled

Running tests

• Run make serve, ensure your server is running
• View your tests at http://localhost:4200/tests/index/html?moduleId=abcd.
• Select the module(s) you want to run from the dropdown at the top right of the page & click "Apply" to run tests.
• To run all tests, remove the ?moduleId=abcd query parameter from the URL.
