📚 General info

• User searches for a station name and Leaflet maps shows location of stations with that name around Paris
• Transloco internationalization (i18n) library for Angular used to enable user to switch between English, Spanish and French. VERSION 4 ONLY - not v5 or v6 or nothing works :-(
• About and Contact pages give more information on app using Tailwind CSS cards
• To build for production Tailwind’s purge option is used to tree-shake unused styles and optimize final build size.
• The Github API does not require an API key for a basic user profile search.
• The Navitia API does require an API key. It is a Hypermedia As The Engine Of Application State (HATEOAS) API that returns JSON formatted results. Using places search
• Angular standalone components used to reduce amount of code and complexity.

• Reactive Extensions Library for Javascript rxjs v7
• Leaflet v1 open-source JavaScript library for mobile-friendly interactive maps
• @ngneat/transloco v4 internationalization (i18n) library for Angular. VERSION 4 ONLY. DO NOT UPDATE OR A LOT OF RECONFIGURATION IS REQUIRED.

• Netlify CLI to deploy app on Netlify

💾 Setup

• Run npm i to install dependencies.
• Get yourself an API key by registering with Navitia.io
• Add API key to the environments.ts file
• Run ng serve for a dev server. Navigate to http://localhost:4200/. The app will automatically reload if you change any of the source files.
• Run npm run build for a production build with css purging.
• Run http-server to view build on an apple/android phone or simulator (pick 2nd http address supplied)
• The build artifacts will be stored in the dist/angular-tailwind-sncf directory.

🔧 Testing

• Run ng test to run Jasmine unit tests via Karma. Currrently 8/12 tests pass

💻 Code Examples

• function from station-list.component.ts to return a list of stations from a user input string

  // search for stations matching user search input
  // observable displayed in template using Angular async pipe
  onSubmitStationSearch(stationSearch: NgForm): void {
    if (this.stations) {
      this.stations = [];
    }
    let searchName = this.sanitizeInput(stationSearch.form.value.stationName);
    if (searchName) {
      this.loading = true; // Set loading state to true
      this.subscription = this.stationService
        .apiStationSearch(searchName, this.stationCount)
        .subscribe((data: SncfResponse[]) => (this.stations = data[0].places));
      this.loading = false; // Set loading state to false after data is fetched
    }
  }

🆒 Features

• standalone components used to reduce boiler-plate code
• Tailwind build for production CSS purge results in a very small styles bundle (about tba kB)

📋 Status & To-Do List

• Status: Working.
• To-Do: Add error-reporting service, language dropdown menu active CSS. Clear map for new search. Make it an SSR. Deploy.
• Optional: Convert to graphQL
