How to build and run image-builder-frontend

Frontend Development

To develop the frontend you can use a proxy to run image-builder-frontend locally against the chrome and backend at console.redhat.com.

Working against the production environment is preferred, as any work can be released without worrying if a feature from stage has been released yet.

Nodejs and npm version

Make sure you have npm@7 and node 15+ installed. If you need multiple versions of nodejs check out nvm.

Webpack proxy

1. run npm ci

2. run npm run prod-beta. This command uses a prod-beta env by default. Configure your environment by the env attribute in dev.webpack.config.js.

3. Secondly redirect a few prod.foo.redhat.com to localhost, if this has not been done already.

echo "127.0.0.1 prod.foo.redhat.com" >> /etc/hosts

4. open browser at https://prod.foo.redhat.com:1337/beta/insights/image-builder

Webpack proxy (staging) -- Runs with image-builder's stage deployment

1. run npm ci

2. run npm run stage-beta. This command uses a stage-beta env by default. Configure your environment by the env attribute in dev.webpack.config.js.

3. Secondly redirect a few stage.foo.redhat.com to localhost, if this has not been done already.

echo "127.0.0.1 stage.foo.redhat.com" >> /etc/hosts

4. open browser at https://stage.foo.redhat.com:1337/beta/insights/image-builder

Insights proxy (deprecated)

1. Clone the insights proxy: https://github.com/RedHatInsights/insights-proxy

2. Setting up the proxy

   Choose a runner (podman or docker), and point the SPANDX_CONFIG variable to profile/local-frontend.js included in image-builder-frontend.

       sudo insights-proxy/scripts/patch-etc-hosts.sh
       export RUNNER="podman"
       export SPANDX_CONFIG=$PATH_TO/image-builder-frontend/profiles/local-frontend.js
       sudo -E insights-proxy/scripts/run.sh
   

3. Starting up image-builder-frontend

   In the image-builder-frontend checkout directory

       npm install
       npm start
   

The UI should be running on https://prod.foo.redhat.com:1337/beta/insights/image-builder/landing. Note that this requires you to have access to either production or stage (plus VPN and proxy config) of insights.

Backend Development

To develop both the frontend and the backend you can again use the proxy to run both the frontend and backend locally against the chrome at cloud.redhat.com. For instructions see devel/README.md.

Style Guidelines

This project uses eslint's recommended styling guidelines. These rules can be found here: https://eslint.org/docs/rules/

To run the linter, use:

npm run lint

Any errors that can be fixed automatically, can be corrected by running:

npm run lint --fix

All the linting rules and configuration of eslint can be found in .eslintrc.yml.

Additional eslint rules

There are also additional rules added to enforce code style. Those being:

• import/order -> enforces the order in import statements and separates them into groups based on their type
• prefer-const -> enforces use of const declaration for variables that are never reassigned
• no-console -> throws an error for any calls of console methods leftover after debugging

Test Guidelines

This project is tested using the Jest framework, React Testing Library, and the Mock Service Worker library.

All UI contributions must also include a new test or update an existing test in order to maintain code coverage.

Running the tests

To run the unit tests, the linter, and the code coverage check run:

npm run test

These tests will also be run in our Travis CI when a PR is opened.
