1. Recline.js

2. Keypress

Keypress is a JavaScript library for capturing keyboard inputs and manipulating them flexibly. It can be used for simple cases (like if “x” is pressed, trigger a function) and more advanced scenarios like creating combos of any type. The library has callbacks for keyup + keydown events, an option exists for capturing the input only once and much more. Source

3. Pace.js

PACE is a JavaScript library for adding good-looking loading bars to any website with ease. There are multiple loading effects: YouTube-like, corner indicator, page fill and more. It requires very less effort; simply insert the JavaScript file with the selected theme and PACE works automatically for page load and ajax requests. The library doesn’t require any JS frameworks and can, optionally, be tweaked manually. Source

4. BackgroundCheck

BackgroundCheck is a small JavaScript library for preventing such issues byauto-changing the style of the element to a darker or lighter one. Once an element overlaps an image, it adds .background–dark or.background–light classes to it. And, creating the related styles for each class would be enough. It is possible to limit the functionality to only selected images, define the dark/light threshold and more. Source

5. TogetherJs

TogetherJS is a free, open source Javascript library by Mozilla that adds collaboration features and tools to your website.

TogetherJS is built and hosted by Mozilla, so you know it’s safe to use. Source
