Running and Testing the TriangleFrontend Project Locally

This guide provides step-by-step instructions to set up, run, and test the TriangleFrontend project on your local machine.

Prerequisites

Before proceeding, ensure you have the following installed on your system:

• Node.js (LTS version recommended)
• npm (comes with Node.js)
• Angular CLI (install globally using npm install -g @angular/cli)

Steps to Run the Project Locally

1. Navigate to the Project Directory

   Open a terminal and navigate to the triangle-frontend directory:

   cd triangle-frontend

   This step ensures you are in the correct directory where the project files are located.

2. Install Dependencies

   Run the following command to install all required dependencies:

   npm install

   This step is crucial because it downloads and installs all the libraries and packages specified in the package.json file. These dependencies are required for the project to build and run correctly.

3. Start the Development Server

   Start the Angular development server by running:

   ng serve

   This command compiles the project and starts a local development server. Once the server is running, open your browser and navigate to http://localhost:4200/ to view the application. The server will automatically reload when you make changes to the source files.

Steps to Test the Project Locally

1. Navigate to the Project Directory

   Ensure you are in the triangle-frontend directory:

2. Run Unit Tests

   Execute the following command to run the unit tests:

   ng test

   This command uses the Karma test runner to execute the unit tests defined in the project. The results will be displayed in the terminal, and a browser window may open to show detailed test results.

   To run the test once and in headless mode (without opening a browser), you can use the following command:

   ng test --watch=false --browsers=ChromeHeadless
