UglifyJS 3
JavaScript parser, mangler, compressor, beautifier toolkit
UglifyJS is a JavaScript compressor/minifier written in JavaScript. It also contains tools that allow one to automate working with JavaScript code. A parser which produces an abstract syntax tree (AST) from JavaScript code. A code generator which outputs JavaScript code from an AST, also providing the option to get a source map. A compressor (optimizer). it uses the transformer API to optimize an AST into a smaller one. A mangler, reduce names of local variables to (usually) single-letters. A scope analyzer, which is a tool that augments the AST with information about where variables are defined/referenced etc. A tree walker, a simple API allowing you to do something on every node in the AST. A tree transformer, another API intended to transform the tree. All the above utilities and APIs are defined in ~6500 lines of code (except for the effective generation of the source-map, which is handled by the source-map module). Compared to alternatives, UglifyJS is pretty small. -

Ultimate React Course
https://github.com/jonasschmedtmann/ultimate-react-course
Ultimate React Course is the official repository for Jonas Schmedtmann’s Ultimate React course. It provides starter files, final project code, and FAQs that support a complete React learning path from fundamentals to more advanced application patterns. The course materials cover modern React development with components, props, state, effects, forms, routing, data fetching, state management, and larger real-world projects. Learners can begin each section from starter code, then compare their work against the final implementation when debugging or reviewing concepts. The repository is primarily an educational companion rather than a reusable app framework. It is useful for students who want a structured React practice environment with many examples built exactly as shown in the course. -

Vue Meta
Manage HTML metadata in Vue.js components with SSR support
Vue Meta is a Vue.js plugin that allows you to manage your app's metadata. It is inspired by and works similar as react-helmet for react. However, instead of setting your data as props passed to a proprietary component, you simply export it as part of your component's data using the meta info property. These properties, when set on a deeply nested component, will cleverly overwrite their parent components' metaInfo, thereby enabling custom info for each top-level view as well as coupling metadata directly to deeply nested subcomponents for more maintainable code. -

WTFJS
A list of funny and tricky JavaScript examples
WTFJS is a curated collection of JavaScript “gotchas” and puzzling examples that reveal surprising corners of the language. Each entry presents a small snippet, explains why the behavior occurs, and ties it back to the specification or engine rules. The repository covers coercion quirks, edge-case comparisons, floating-point oddities, prototype traps, and scoping pitfalls, among others. It’s designed as both a fun read and a serious learning aid, helping developers build an intuition for how JavaScript evaluates expressions. By highlighting common misconceptions, it encourages safer coding patterns and more reliable mental models. Teachers, interviewers, and learners use it to spark discussion and deepen understanding of JavaScript’s semantics. -

Wasp
A programming language that understands what a web app is
Wasp (Web Application Specification Language) is a declarative DSL (domain-specific language) for developing, building and deploying modern full-stack web apps with less code. Concepts such as app, page, user, login, frontend, production, etc. are baked into the language, bringing a new level of expressiveness and allowing you to get more work done with fewer lines of code. While describing high-level features with Wasp, you still write the rest of your logic in your favorite technologies (currently React, NodeJS, Prisma). Wasp is in alpha and is therefore likely to change a lot, have bugs and miss important features. Due to its expressiveness, you can create and deploy a production-ready web app from scratch with very few lines of concise, consistent, declarative code. When you need more control than Wasp offers, you can write code in existing technologies such as js/html/css/... and combine it with Wasp code! -

bors-ng
A merge bot for GitHub Pull Requests
bors-ng is a GitHub merge bot that enforces an “evergreen” main branch by queueing approved pull requests, testing them together on a staging branch, and only advancing main with the exact, passing commit set. Instead of maintainers repeatedly rebasing and merging one PR at a time, bors-ng batches r+-ed PRs, triggers your existing CI (e.g., GitHub Actions), and merges automatically when the batch is green. If a batch fails, it bisects the batch into smaller runs to isolate the culprit, landing the good PRs and kicking only the failing one(s) back for fixes. The bot is implemented as a GitHub App and works alongside—rather than replacing—your CI by reporting commit statuses/checks and acting on PR comments like bors r+ or bors try. It provides a dashboard to watch queue progress, uses separate staging/trying branches for merge/test cycles, and supports both public GitHub and GitHub Enterprise endpoints. -

electron-store
Simple data persistence for your Electron app or module
Simple data persistence for your Electron app or module. Save and load user preferences, app state, cache, etc. Electron doesn't have a built-in way to persist user preferences and other data. This module handles that for you, so you can focus on building your app. You can use this module directly in both the main and renderer process. For use in the renderer process only, you need to call Store.initRenderer() in the main process, or create a new Store instance (new Store()) in the main process. Changes are written to disk atomically, so if the process crashes during a write, it will not corrupt the existing config. Under the hood, the JSON Schema validator ajv is used to validate your config. We use JSON Schema draft-07 and support all validation keywords and formats. You should define your schema as an object where each key is the name of your data's property and each value is a JSON schema used to validate that property. -

find-my-way
A crazy fast HTTP router
A crazy fast HTTP router, internally uses a highly performant Radix Tree (aka compact Prefix Tree), supports route params, wildcards, and it's framework is independent. You can set a custom length for parameters in parametric (standard, regex and multi) routes by using maxParamLength option, the default value is 100 characters. If you are using a regex-based route, find-my-way will throw an error if detects potentially catastrophic exponential-time regular expressions (internally uses safe-regex2). According to RFC3986, find-my-way is case-sensitive by default. You can disable this by setting the caseSensitive option to false: in that case, all paths will be matched as lowercase, but the route parameters or wildcards will maintain their original letter casing. -

hiproxy
hiproxy is a lightweight proxy tool for Front-End developers
hiproxy is a lightweight web proxy tool based on Node.js. The primary purpose of hiproxy is to solve the problem of host management and reverse proxy needs of developers. For example, if you are working as a team and each of the developers in the team need a different proxy setting, you will no longer need to modify your hosts file or use a web server like Nginx as a reverse proxy. hiproxy extends the syntax of hosts file to support port numbers. Besides, hiproxy also supports configuration through a syntax similar to the Nginx configuration file. To develop your web projects in a local development environment, you’ll have to run a back-end server (such as a Node.js express application, or a Java SpringBoot application). As a front-end developer, you might not be familiar with the back-end technology stack, simply setting up the development environment can consume a lot of your time. -
