Website Performance Optimization portfolio project
Your challenge, if you wish to accept it (and we sure hope you will), is to optimize this online portfolio for speed! In particular, optimize the critical rendering path and make this page render as quickly as possible by applying the techniques you've picked up in the Critical Rendering Path course.
To get started, check out the repository and inspect the code.
####Part 1: Optimize PageSpeed Insights score for index.html
Some useful tips to help you get started:
- Check out the repository
- To inspect the site on your phone, you can run a local server
$> cd /path/to/your-project-folder $> python -m SimpleHTTPServer 8080
- Open a browser and visit localhost:8080
- Download and install ngrok to make your local server accessible remotely.
$> cd /path/to/your-project-folder $> ngrok http 8080
- Copy the public URL ngrok gives you and try running it through PageSpeed Insights! Optional: More on integrating ngrok, Grunt and PageSpeed.
Profile, optimize, measure... and then lather, rinse, and repeat. Good luck!
####Part 2: Optimize Frames per Second in pizza.html
To optimize views/pizza.html, you will need to modify views/js/main.js until your frames per second rate is 60 fps or higher. You will find instructive comments in main.js.
You might find the FPS Counter/HUD Display useful in Chrome developer tools described here: Chrome Dev Tools tips-and-tricks.
Optimization Tips and Tricks
- Optimizing Performance
- Analyzing the Critical Rendering Path
- Optimizing the Critical Rendering Path
- Avoiding Rendering Blocking CSS
- Measuring with Navigation Timing. We didn't cover the Navigation Timing API in the first two lessons but it's an incredibly useful tool for automated page profiling. I highly recommend reading.
- The fewer the downloads, the better
- Reduce the size of text
- Optimize images
- HTTP caching
Customization with Bootstrap
The portfolio was built on Twitter's Bootstrap framework. All custom styles are in
dist/css/portfolio.css in the portfolio repo.
