Website Performance Optimization portfolio project

Optimizations

updates to views/js/main.js

Based on the FEND Office Hours

• refactored loops to remove duplicated or unessesary events form loops for the updatePositions() and changePizzaSizes(size) functions.
• added getDomNodeArray(selector) from Instructor notes in class to use forEachloops
• removed the generateDX function and rewrote the changePizzaSizes() function to use the getDomNodeArray(selector) function
• rewroterequestAnimation() function per the Animation Tutorial @ HTML5ROCKS.com
• added onScroll() and updated the event listener
• added backface-visibility: hidden to the .mover class elements to use GPU painting
• switched out document.querySelector for the better performing document.getElementByID

updates to index.html

• optimized images based on results from [Google Page Speed]
• moved CSS and Javascript to end of file and switched to Async loads
• minimized the HTML file

Running the portfolio

1. To inspect the site, you can run a local server, I use WAMPServer

2. Check out the repository, into your webserver root folder, WAMPServer will pickup the folder automatically.

3. Open a browser and visit localhost:<<PORT_NUMBER>>

4. To use the Google Page Speed Insights site you will need to download and install ngrok to make your local server accessible remotely.

$> cd /path/to/your-project-folder
$> ngrok <<PORT_NUMBER>>

1. Copy the public URL ngrok gives you and try running it through PageSpeed Insights! Optional: More on integrating ngrok, Grunt and PageSpeed.

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, inspect the code,

Getting started

####Part 1: Optimize PageSpeed Insights score for index.html

Some useful tips to help you get started:

1. Check out the repository
2. To inspect the site on your phone, you can run a local server

$> cd /path/to/your-project-folder
$> python -m SimpleHTTPServer 8080

1. Open a browser and visit localhost:8080
2. Download and install ngrok to make your local server accessible remotely.

$> cd /path/to/your-project-folder
$> ngrok 8080

1. 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
• Optimizing JavaScript
• 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.

• Bootstrap's CSS Classes
• Bootstrap's Components
