Top GitHub Repositories for Front-end Developers
GitHub, that hosts over 85M code repositories and has about 28M users, has become one of the most popular pitstop for front-end developers. From frameworks and demonstrations to libraries and collections – there is a universe worth of things to explore for every developer on GitHub.
But this overwhelmingly large quantity of repository makes it tricky to unearth the cooler things you probably don’t hear about very easily – simply because there are so many resources available.
So here we have a short list of popular GitHub repositories to explore if you are a front end developer. Each of them has at least ~20,000 stars
1. Front-End Checklist
Before you launch your web applications to your end-users, wonder what you need to have ready or to test it out before actually making things live? The Front end checklist has all items that are required by the majority of the projects.
Their items listed are mandatory for the majority of projects and organized as follows:
The repository provides a range of flexibility:
- The green symbol means that the repository item is recommended but you can avoid it in situations (say you are creating a web-based admin app that may not require RSS feed)
- The orange triangle means that item is highly recommended and be omitted at some stage in peculiar cases but there may be repercussions in terms of performance
- The red symbol signifies that the item simply cannot be omitted and you must utilize it to avoid any dysfunction on your page or have accessibility issues. The testing priority needs to be on these elements first.
The repository has made it far too intuitive and accessible to developers using emoticons to help you understand which type of content/help you may find on the checklist:
- ?: documentation or article
- ?: online tool/testing tool
- ?: media or video content

2. Big List of Naughty String
The big naughty list is an extremely useful list for testing user inputs. This repository offers an evolving list of strings that are likely to cause issues when used as user inputs while testing your code.
“Even multi-billion dollar companies with huge amounts of automated testing can’t find every bad input,” writes the GitHub repo highlighting just how in-depth its collection of user inputs that are meant to reveal any issues in your application.
So whether you are running manual tests or automated tests, this repository will help you find the strings that have a high probability of causing an issue for the end-user. It will help you spot the errors in advance to ensure a positive user experience.
It laid out how you need to use the repo. Its blns.txt consists of the newline-delimited strings and comments which are preceded with the hash #. The comments divide the strings into sections for easy manual reading and copy/pasting into input forms. For those who want to access the strings programmatically, a blns.json file is provided containing an array with all the comments stripped out (the scripts folder contains a Python script used to generate the blns.json).
So, if you are exploring user-input validations, or you are into testing, give this repo a look > the big list of naughty strings.
