The Best JavaScript and CSS Libraries for 2017

Our mission at Tutorialzine is to keep you up to date with the latest and coolest trends in web development. Over the last year, we presented you a number of interesting libraries and resources, that we thought are worth checking out. That's why in this article we decided to share with you a collection of those, that stood out the most.



Wrapper for indexedDB and WebSQL that improves the ability of web apps to store data locally for offline use. Writing and reading is done in a similar fashion to localStorage but many types of data can be saved instead of only strings. It also offers a dual API, which gives developers the choice to use either callbacks or promises. You can find more about it in our Make IndexedDB a Breeze With LocalForage article.



AOS is a CSS library that allows you to add on scroll animation effects. The library is highly customizable, very tiny, easy to use (install via CDN), and most importantly performs well, which can be an issue with other animate on scroll libraries.



MJML is a simple XML-like language that provides simple markup syntax with various stylized components that can be compiled to email-friendly HTML. This way we don't have to manually code entire layouts out of tables and legacy in-line styles. It also offers a rich set of standardized components with various customization options. For more detailed information, you can check our Building Responsive Emails with MJML tutorial.


Monaco editor

The editor engine behind Microsoft's Electron based Visual Studio Code.

This futuristic library allows you to create virtual reality experiences using only good ol' web technologies. After you've created your 3D world in HTML, A-frame will take it and split it into two screens with slightly different viewing angles. Now, you can run your demo on your mobile phone using Google Cardboard or another headset and have some serious VR fun.


Bootstrap 4

Bootstrap 4 brings many changes and new features to the grid system we are all so familiar with from version 3. The new version of the framework brings forth a lot of great changes, including a flexbox-based grid system, new and restyled components, and faster ES6 JavaScript plugins. Another cool new feature is the auto-layout mode. It allows developers to leave out the size of columns, making them automatically distribute the space in that row.

Puppeteer is a high-level Node.js API for working with the new headless Chrome feature. It is an official Google project maintained by the Chrome DevTools team.

You can read more about it in our article Automating Google Chrome with Node.js where we try out some of its features.



Push is the fastest library for managing JavaScript desktop notifications. It is based on the powerful Notification API but also acts as a reliable cross-browser solution, falling back to older implementations if the user’s browser does not have support for the new API.
