My web application is built using Angular Universal Starter kit. I'm looking to optimize the initial page load speed by uploading the pre-rendered file to an S3 bucket. However, I am having trouble finding the correct configurations for uploading the pre-rendered file to S3 and accessing it on the initial load. Can anyone provide guidance on how to achieve this?
When it comes to Angular Universal, you have the option to utilize both Dynamic SSR (server-side rendering) and Static Pre-rendering.
Dynamic SSR requires a server-side Javascript engine (like nodejs) to pre-render the page before serving it to the client browser. This functionality cannot be achieved with platforms such as AWS S3, which are designed for static file hosting only.
On the other hand, Static Pre-rendering with Angular Universal can work seamlessly with AWS S3 since it involves serving static html/js/css files. However, keep in mind that whenever there are changes to the static content, a build/CI-CD process needs to be initiated to deploy the updated files to the S3 bucket.
For example,
aws s3 sync ./dist/<your_awesome_ng_project> s3://<your_awesome_bucket_name>/ --deleteIf you want to dive deeper into Dynamic SSR and Static Pre-rendering, check out this insightful article
Pre-rendering typically offers better performance by avoiding server delays and serialization processes. It is ideal for static or less frequently updated applications.
Your application's content remains mostly static or changes infrequently.
Dynamically changing parts of your site can utilize Client-Side Rendering (CSR), leaving pre-rendered routes untouched.
You prefer a straightforward build process to update static routes when necessary.
In most scenarios, Static Pre-rendering suffices unless specific requirements demand Dynamic SSR benefits. Remember, Angular Universal can accommodate both approaches based on your project's needs.
For more insights, including discussions on using NGINX as a static file server instead of S3, visit this link: https://github.com/angular/universal/issues/554
Also worth noting that Angular Universal is now integrated into the main ng project
If you found this response helpful, feel free to share it with others seeking similar guidance even if it may be slightly delayed from the original query.
When it comes to using a pre-rendered HTML, it's essentially the equivalent of uploading a static website. Assuming you have the aws cli properly installed and configured (by running aws configure), you can execute the command below in your directory to upload the file to an s3 bucket.
This action will solely upload or update files that differ from those currently present in the bucket.
aws s3 sync my_local_dir s3://my_s3_bucket_name
In addition, should you wish to apply a cache setting, you can include the following option:
aws s3 sync my_local_dir s3://my_s3_bucket_name --cache-control max-age=604800
In my current organization, we successfully implemented a strategy to cater to the dynamic content on our website, particularly related to inventory. We made a conscious decision to send pre-rendered pages only to web crawlers, while real users accessed the dynamic content directly. This approach was adopted for several reasons:
To achieve this, we set up a rule on our nginx server to redirect requests from search engine user-agents to a dedicated pre-render server equipped with https://github.com/prerender/prerender.
Additionally, the pre-render server was configured with the s3HtmlCache plugin, which checked for page availability in S3 storage. If the page was not found, it dynamically generated and cached the page runtime before sending it to the client.
If you are facing similar challenges, consider implementing a similar setup on your nginx server to direct all requests to a pre-render server. Feel free to reach out if you encounter any issues as I have experience implementing this solution successfully. Best of luck!
