create first angular app step-by-step

In this Article, Learn how to globally install Angular, set up an Angular app from scratch, and build your first Angular application with ease. This comprehensive guide will walk you through each step, from installing Angular globally to deploying your app.

Are you ready to embark on your journey into web development with Angular? Look no further! In this step-by-step guide, we'll take you through the process of creating your first Angular app from scratch. Whether you're new to Angular or just need a refresher, we've got you covered.

Prerequisites

Before we begin, ensure that you have the following tools installed on your computer:

1. Node.js: Angular relies on Node.js for package management and server-side operations. Download and install it from the official website.

2. npm (Node Package Manager): npm is included with Node.js, so you should have it installed after completing the Node.js installation.

3. Global Angular Installation: To create Angular applications, you'll need to install Angular CLI globally. Open your terminal/command prompt and enter the following command:

npm install -g @angular/cli

Now that you have the necessary prerequisites, let's start building your Angular app!

Step 1: Create a New Angular App

To create a new Angular app, open your terminal/command prompt and enter the following command:

ng new my-angular-app

Replace my-angular-app with the name you want to give your app. This command will generate a new Angular project with all the required files and dependencies.

Step 2: Navigate to Your Project

Once the command has finished, navigate to your project folder:

cd my-angular-app

Step 3: Serve Your Angular App

Now, serve your Angular app by running:

ng serve

This command will compile your Angular app and launch a development server. You should see a message indicating that the app is running at http://localhost:4200/. Open this URL in your web browser to view your app.

Step 4: Edit Your Angular App

Open the project folder in your preferred code editor (e.g., Visual Studio Code, Sublime Text, or Atom). Your project is located in the folder you created earlier (my-angular-app in this example).

Edit the src/app/app.component.ts file to make changes to your Angular app. As you save your changes, the development server will automatically update the app in your browser.

Step 5: Build and Deploy

Once you've made the desired changes to your Angular app, you can build it for production using:

ng build --prod

This command will create an optimized build of your app in the dist folder. You can then deploy this build to a web server or hosting service of your choice.

Congratulations! You've successfully created and deployed your first Angular app. This marks the beginning of your exciting journey into Angular development.

Conclusion

In this guide, we've covered the essential steps to create an Angular app from scratch. We installed the necessary tools, globally installed Angular CLI, generated a new Angular project, served our app, edited it, and prepared it for deployment. You now have a solid foundation to explore the powerful features of Angular and build impressive web applications.

Happy coding!
