Creating a full-fledged website and application that drives the target audience has become pivotal in the development space. Thus, developers emphasize choosing the right frontend and backend frameworks to run a successful campaign. For frontend development, frameworks such as Angular and React have gained significant traction over the past few years. On the contrary, for managing the backend development, hosting providers such as AWS (Amazon Web Services) offer a feasible cloud computing platform to manage the website or application. In this article, we will dive deep into how the amalgamation of these cutting-edge technologies will pave the web development space in the future.
Developed by Google, Angular is a popular open-source framework for creating dynamic, single-page web applications (SPAs). It provides a comprehensive solution for front-end development, including tools for building scalable, modular, and responsive applications. With features like two-way data binding, dependency injection, and a powerful CLI, Angular simplifies the development process and enhances productivity. Its widespread use and robust community support make it an excellent choice for developers creating modern web applications.
Amazon Web Services (AWS) is a comprehensive cloud computing platform offering a broad range of services such as computing power, storage, databases, networking, and machine learning. It provides a scalable infrastructure that is essential for deploying, managing, and scaling applications. For Angular developers, AWS offers services like Amazon S3 for storage, AWS Lambda for serverless computing, Amazon API Gateway for managing APIs, and AWS Cognito for authentication, making it an ideal choice for hosting and scaling Angular applications.
1. Scalability
AWS offers scalable infrastructure, allowing you to easily handle growing traffic with services like EC2, S3, and RDS. On the contrary, Angular's modular design supports scalability with features like lazy loading and reusable components, ensuring your application can grow smoothly without compromising performance.
2. Security
AWS provides robust security features such as IAM, encryption, and protection from DDoS attacks through AWS Shield and WAF. On the other hand, Angular enhances security with built-in protections against XSS, CSRF, and XSRF vulnerabilities, ensuring both your front-end and back-end are secure.
3. Cost-Effectiveness
AWS’s pay-as-you-go model allows you to pay only for what you use, offering flexibility and cost savings. Additionally, Angular is free and open-source, reducing licensing and development costs, while its efficiency speeds up the development process, saving both time and money.
Thus, Angular and AWS together offer a scalable, secure, and cost-effective solution for building and deploying web applications.
Deploying an Angular application to the cloud provides a seamless way to host and share your web app with the world. If you are an Angular developer looking for an easy yet reliable solution, AWS (Amazon Web Services) offers an excellent set of tools to host your Angular apps. This blog post will guide you through deploying your Angular application to AWS S3, leveraging AWS CloudFront for faster content delivery, and using AWS Amplify for continuous deployment.
This guide is beginner-friendly and will help deploy the Angular app with ease. It can help easily host your static website on the AWS cloud, using some of the most powerful AWS services.
Before diving into the deployment process, the following are the prerequisites:
AWS Account: You must have an active AWS account. If you do not have one, you can create it easily by visiting the AWS website.
Angular CLI: The Angular CLI is necessary to build and serve your Angular app. If you have not installed it yet, use the following command:
bash
npm install -g @angular/cliAWS CLI: Install the AWS CLI on your machine for easier command-line interaction with AWS services. The installation instructions can be found in the official AWS CLI guide.
Angular Application: Make sure your Angular app is ready for deployment. If you are starting from scratch, you can create a new Angular app using the Angular CLI with the following command:
bash
ng new my-angular-appThis will create an Angular project with the necessary files.
Before deploying to AWS, you must build your Angular app for production. The Angular CLI provides a simple command to optimize your app for deployment. Open your terminal and navigate to the project folder where your app resides, then run:
bash
ng build --prodThis command compiles your app’s Angular application files and generates a dist/ folder, which contains all the static assets (HTML, CSS, JavaScript, images) required to run your app. These files will be uploaded to AWS S3.
Before deploying, it is a good idea to test your built Angular app locally. To do this, you can serve the static website files using a simple command. If you do not already have a server, you can install the http-server package via npm:
bash
npm install -g http-serverThen, navigate to the dist/ folder and run:
bash
http-server -oThis will open your app in the browser, allowing you to preview the static website before uploading it to the AWS cloud.
Now that we have built the app and verified it locally, let us move on to deploying it to AWS.
Log in to the AWS Management Console: Start by logging into the AWS Management Console. Once logged in, navigate to the S3 service.
Create a New S3 Bucket:
Click on Create bucket to start a new S3 bucket.
Choose a globally unique name for your bucket (e.g., my-angular-app-bucket).
Select an appropriate region that is geographically close to your target audience.
Disable Block all public access under bucket settings to allow public access to your static assets (i.e., Angular app files).
Click Create.
Enable Static Website Hosting:
In the Properties tab of your new bucket, scroll down to Static website hosting.
Enable static website hosting and specify:
Index document: index.html(starting page of your website)
Error document: error.html(error page )
Save your changes.
Upload Files to S3:
Go to the Objects tab within your bucket.
Click on Upload and select all the files in the dist/ folder from your Angular app. This will upload the static assets to your S3 bucket.
Set Bucket Policy for Public Access:
To make your app accessible to the public, go to the Permissions tab of your bucket.
Add a bucket policy under Bucket Policy to grant public read access:
This policy allows public access to all the files in your bucket.
After uploading the files and setting the bucket policy, go to the Properties tab of your bucket. Under Static Website Hosting, you will see an Endpoint URL. This URL is where your static website is hosted.
For example:
http://my-angular-app-bucket.s3-website-us-east-1.amazonaws.comYou can open this URL in your browser to view your live Angular app hosted on AWS!
To make your Angular app load faster for users around the world, you can set up AWS CloudFront, which is a content delivery network (CDN). CloudFront caches your app’s static assets at edge locations around the globe, providing faster access to users.
Create a CloudFront Distribution:
Navigate to CloudFront in the AWS Management Console.
Click Create Distribution and select the Web delivery method (or this may be the only default option in newer AWS versions).
Under Origin Settings, provide:
Origin Domain Name: Select or enter the name of the S3 bucket you created earlier. Make sure the bucket is configured for static website hosting.
Origin Access Control: You can configure this if you would like CloudFront to access a private bucket securely (using an origin access identity). For public buckets, this step can be skipped.
Viewer Protocol Policy:
Set Redirect HTTP to HTTPS to ensure secure connections for your app. This is good for security and SEO.
Default Behavior Settings:
Set Allowed HTTP Methods: GET, HEAD (and optionally OPTIONS).
Enable Compress Objects Automatically: This compresses assets like JS, CSS, and HTML to improve performance.
Custom Error Pages:
For single-page applications (like Angular), configure error handling to serve the index.html for 404 errors.
Add a custom error response for 403 or 404 errors:
HTTP Error Code: 403 or 404.
Customize Error Response: Redirect to /index.html.
Configure a CNAME Record for Custom Domains:
Obtain the CloudFront distribution's domain name (e.g., d123abc.cloudfront.net).
Go to your domain registrar (e.g., Route 53, GoDaddy, or Namecheap).
Add a CNAME record pointing your custom domain (e.g., www.my-angular-app.com) to the CloudFront distribution domain.
Ensure you have an SSL certificate:
Deploy AWS Certificate Manager (ACM) to create a free SSL/TLS certificate for your custom domain.
Deploy Your App:
Once CloudFront is deployed (it may take several minutes), your Angular app will be accessible using the CloudFront domain or your custom domain.
Caching Behavior: CloudFront may cache files aggressively. If you make updates to your app, you may need to invalidate the cache to reflect changes immediately. You can do this in the CloudFront console under Invalidations.
Domain Validation: If you configure a custom domain, ensure the DNS configuration is validated, especially for SSL certificates.
Seamless Integration with Git Repositories
AWS Amplify connects directly to popular Git services like GitHub, GitLab, and Bitbucket, enabling smooth workflows.
Automated Builds and Deployments
Every time you push changes to your Git repository, Amplify automatically builds and deploys your app. This feature ensures your live site always reflects the latest updates.
Custom Domain Management
Amplify provides an easy setup for a custom domain, whether you own one already or purchase through AWS. It handles domain registration, SSL certificates, and DNS records for you.
For developers looking to automate the deployment process, AWS Amplify offers a powerful solution. AWS Amplify integrates with your Git repository (e.g., GitHub) and automatically deploys updates whenever you push new changes.
Set Up AWS Amplify:
Go to AWS Amplify in the AWS Management Console and click on Get Started under Host Web App.
Connect your Git repository (GitHub, GitLab, Bitbucket) and choose the branch you want to deploy.
Automatic Builds: Once connected, AWS Amplify automatically detects that you are working with an Angular application and configures the build settings. Amplify will then build and deploy your app automatically every time you push code to your Git repository.
Custom Domain Setup: AWS Amplify also allows you to set up a custom domain for your app.
Continuous Deployment: With AWS Amplify, the deployment process is continuous. Any changes made to your app’s code are automatically reflected on the live site, ensuring your users always see the latest version.
Deploying an Angular app on AWS is simple and powerful, thanks to the combination of AWS S3, CloudFront, and AWS Amplify. These services make it easy for Angular developers to host static websites, improve app performance through a content delivery network, and automate the deployment process using a git-based workflow.
