What are some best practices for optimizing website performance?

Question

Hey everyone! I'm working on improving the performance of my website, and I'm looking for some expert advice. What are some best practices and techniques I can implement to optimize the performance of my website, particularly in terms of loading speed and responsiveness? Any specific tips or tools you recommend? Thanks in advance for your help!

Answer 1

Minify your code. If available use lazy loading. Compress static files (I'm looking at you, images!). Use async methods and loading as much as possible. Rewrite critical code in webassembly (probably won't need this as much as you think). Hydrate your data models. Move some of the page building to the server side if you can; balance as much as you can between having the server do intense business logic and app building, and the client displaying updates to the data model. Be strategic with tracking software; you don't need to see every click and log every key stroke, just the ones you care about. Time your middleware calls and look for opportunities to speed up load times by preemptively calling those services when possible. Cache data. Download files (libraries, fonts, etc.) to your project rather than using script tags to load them. Get clever with your CSS and use it to replace JavaScript whenever possible.

Do not try to pour caffeine on the server.
