setting up an angular environment and deploying your application efficiently involves several steps, from initializing your angular project to preparing it for production. here’s a comprehensive tutorial on angular environment setup and deployment best practices.

angular environment setup

step 1: install node.js and npm

before you begin, ensure you have node.js and npm (node package manager) installed on your machine. you can download them from [node.js official website](https://nodejs.org/).

to check if node.js and npm are installed, run the following commands:

```bash
node -v
npm -v
```

step 2: install angular cli

angular cli (command line interface) is a powerful tool that helps you to create, manage, and deploy angular applications. you can install it globally using npm:

```bash
npm install -g @angular/cli
```

to verify the installation, run:

```bash
ng version
```

step 3: create a new angular project

you can create a new angular project using the following command:

```bash
ng new my-angular-app
```

this command will prompt you for some configuration options, such as whether to include angular routing and which stylesheet format to use (css, scss, etc.).

step 4: serve the application locally

navigate into your project directory and serve the application:

```bash
cd my-angular-app
ng serve
```

by default, the application runs at `http://localhost:4200/`.

angular environment configuration

angular applications often have different configurations for different environments (development, production, etc.). you can manage this using angular’s built-in environment files.

step 5: set up environment files

in your angular project, you will find an `environments` folder under `src`. it contains two files by default:

`environment.ts` (for development)
`environment.prod.ts` (for production)

you can define environment-specific variables in these files. for example:

*src/environments/environment.ts* (development)

```typescript
export cons ...
