    Underscore.js

    Underscore.js

    JavaScript's utility belt

    Underscore.js is a JavaScript utility-library created by Jeremy Ashkenas that provides a broad set of functions for working with arrays, objects, functions, and other data types — essentially a “utility belt” for functional programming in JS. Instead of extending built-in objects or modifying prototypes, Underscore provides its helpers in a single _ namespace, enabling cross-browser support and consistent behaviour across environments. It offers map/filter/reduce, deep-cloning, templating,...

    Backbone

    Backbone

    Give your JS app some Backbone with models, views, and collections

    Backbone is a lightweight JavaScript library (sometimes described as a micro-framework) created by Jeremy Ashkenas that adds structure to JavaScript-heavy applications by providing models, views, collections, events and routing tied to RESTful JSON services. Its main philosophy is to provide the minimal set of primitives to organise your client-side code — models for data, collections for groups of models, views for UI interactions, and routers for state/URL management — without prescribing...

    Large single page application with 45 pages built on vue2 + vuex

    vue2-elm is a hands-on Vue 2 application that recreates the core experience of the Ele.me food-delivery app to teach modern front-end architecture. It uses Vue components, routing, and state management to stitch together pages like restaurant listings, detail views, carts, and user flows. The project illustrates how to organize a medium-sized SPA, including how to split features into reusable pieces and handle asynchronous data. It places strong emphasis on responsive UI, transitions, and...

    Node.js Testing Best Practices

    Node.js Testing Best Practices

    Beyond the basics of Node.js testing

    This repository narrows the testing lens to Node.js backends, focusing on the challenges of servers, microservices, and cloud-native deployments. It covers API testing, contract testing, and persistence-layer strategies that avoid coupling tests to fragile implementation details. The material explains how to structure tests around process boundaries—HTTP, queues, cron jobs—while keeping fast feedback cycles through selective integration tests and reliable test doubles. It dives into topics...

    NanoNeuron

    NanoNeuron

    NanoNeuron is 7 simple JavaScript functions

    Nano-Neuron is a didactic project that reduces the idea of a neuron to a handful of tiny JavaScript functions so learners can see “learning” in action without heavy frameworks. It demonstrates how a scalar input can be linearly transformed with a weight and bias, then adjusted via gradient updates to fit a simple mapping such as Celsius-to-Fahrenheit conversion. The code emphasizes readability over performance, inviting you to step through calculations and watch parameters converge. Because...

    Google API JavaScript Client

    Google API JavaScript Client

    Google APIs Client Library for browser JavaScript, aka gapi

    This library (often used via gapi) provides a browser-friendly way to call Google APIs using OAuth 2.0 and generated discovery documents. It abstracts discovery, auth, and HTTP details so developers can focus on domain calls like Drive file operations, Calendar events, or YouTube data. The client can load APIs dynamically at runtime, which keeps bundles small and allows late-binding to specific services and versions. It includes helpers for incremental auth, token refresh, and scopes so apps...

    A simple git hooks manager for small projects

    A simple git hooks manager for small projects. A git hook is a command or script that is going to be run every time you perform a git action, like git commit or git push. If the execution of a git hook fails, then the git action aborts. For example, if you want to run linter on every commit to ensure code quality in your project, then you can create a pre-commit hook that would call npx lint-staged. Check out lint-staged. It works really well with simple-git-hooks. You can look up about git...

    The conventional-changelog repo is managed as a monorepo; it's composed of many npm packages. It's recommended you use the high-level standard-version library, which is a drop-in replacement for npm's version command, handling automated version bumping, tagging, and CHANGELOG generation. Alternatively, if you'd like to move towards completely automating your release process as an output from CI/CD, consider using semantic-release.

    Component/integration test is a hybrid between E2E and unit tets. It's gaining a lot of popularity and going by the testing diamond model it is considered as the default technique for the modern backend. Its main idea is testing an entire component (e.g., Microservice) as-is, through the API, with all the layers including the database but fake anything extraneous. This brings both high confidence and great developer experience. However, doing it right, fast, exhaustive and maximizing the...

    Composable Ember applications for ambitious user experiences

    Engines allow multiple logical applications to be composed together into a single application from the user's perspective. The key term here is "logical application". That is, an Engine represents a set of functionality and user experiences that could logically be considered an application. However, they differ from normal Ember applications in that they are intended to be composed within a host application in order to create a single, cohesive user experience. On a technical level, engines...
