1. Build Your Angular Application

Before deployment, create a production-ready build:

ng build --configuration=production

2. Deploying on Different Platforms

A. Firebase Hosting

1. Install Firebase CLI:

npm install -g firebase-tools

      2. Login to Firebase:

firebase login

      3.  Initialize Firebase in the project

firebase init

• Select Hosting
• Choose an existing Firebase project or create a new one
• Set dist/project-name as the public directory

4. Deploy the project:

firebase deploy

B. Vercel Deployment

1. Install Vercel CLI:

npm install -g vercel

       2. Login to Vercel:

vercel login

C. Deploying on Netlify

npm install -g netlify-cli

Login to Netlify:

netlify login

Deploy the project:

netlify deploy --prod

D. Deploying on AWS S3

1. Build the project:

ng build --configuration=production

1. Upload the dist folder to an S3 bucket using the AWS console.
2. Enable Static Website Hosting in the bucket settings.

Best Practices for Angular Deployment

✅ Enable Production Mode
Modify main.ts to enable production mode:

import { enableProdMode } from '@angular/core';
if (environment.production) {
  enableProdMode();
}

✅ Lazy Load Modules
Improve performance by using lazy loading in app-routing.module.ts:

const routes: Routes = [
  { path: 'dashboard', loadChildren: () => import('./dashboard/dashboard.module').then(m => m.DashboardModule) }
];

✅ Optimize Bundle Size

1. Use Tree Shaking to remove unused code:

ng build --prod

1. Enable gzip compression on the server to reduce file sizes.

✅ Secure API Calls

• Use environment variables for API keys instead of hardcoding them.
• Implement JWT authentication for API security.

✅ Monitor and Optimize Performance
Use Lighthouse or Google PageSpeed Insights to analyze and improve performance.

Conclusion

Deploying an Angular application requires proper hosting setup, performance optimization, and security measures. Whether using Firebase, Vercel, Netlify, or AWS, following best practices ensures a fast, scalable, and secure application. 🚀
