1. Install NodeJS Installer

Note, for those using linux, you can find instruction to install NodeJS here (install the latest LTS Version 14.15.4).

2. Fork this repository

Click on the fork button on the page of the repository on github to create your own copy of the starter.

3. Clone your repository, your fork

git clone https://github.com/YOUR_USERNAME/starter-quiz-2022.git

4. Install the dependencies

Open command prompt inside the repository (starter-quiz-2022) and run:

npm install

If you have an error saying that npm is not a known command, it means that NodeJS is not installed.

5. Install angular/cli

npm install -g @angular/cli

npm start

Then navigate to http://localhost:4200/ to see the application. The app will automatically reload if you change any of the source files.

You can also use the command ng serve to start the app and also ng serve --open to open directly the app in the browser.

The linter is a tool which automatically detects static code issues (such as unused imports or variables, trailing whitespaces etc...).

To run it:

npm run lint

If you get an error saying that Missing script: "lint", then you can run : ng lint. Then, you should be able to run the linter. Note: for this project, we will disable a rule from the default linter, edit your .eslintrc.json to disable the rule "@angular-eslint/no-empty-lifecycle-method": "off", edit the "rules" array as follow:

 "rules": {
        "@angular-eslint/no-empty-lifecycle-method": "off",
        "@angular-eslint/directive-selector": [
          "error",
          {
            "type": "attribute",
            "prefix": "app",
            "style": "camelCase"
          }
        ],
        "@angular-eslint/component-selector": [
          "error",
          {
            "type": "element",
            "prefix": "app",
            "style": "kebab-case"
          }
        ]
      }

Several issues from the linter can be fixed automatically (for instance: trailing whitespace, missing new line etc...) thanks to the following command:

npm run lint -- --fix

But you will have to manually manage the other types of error.

The best documentation is the Official Angular Documentation. It contains everything and it is always up to date.

We are working with Angular version 2+ (here Angular 8). When you look for some documentation, add "Angular 2" in your research to be sure to find the right documentation. You might find documentation about AngularJS, run if it's the case! It's a very old version totally different from our version.

Documentation Angular:

• Directives
• Pipes
• Services
• HTTP Request with Angular
• NgOnInit
• @Input and @Ouput

Documentation on Observables:

• Official Documentation rxjs
• Video Tutorial for beginers - FR
• Tutorial FR

Any question? Do not hesitate to contact us on slack for any question.

Run ng generate component component-name to generate a new component. You can also use ng generate directive|pipe|service|class|guard|interface|enum|module.
