Configure your Node.js Applications
Node.js application configuration
Node-config organizes hierarchical configurations for your app deployments. It lets you define a set of default parameters, and extend them for different deployment environments (development, qa, staging, production, etc.). Configurations are stored in configuration files within your application, and can be overridden and extended by environment variables, command line parameters, or external sources. This gives your application a consistent configuration interface shared among a growing list of npm modules also using node-config. config.get() will throw an exception for undefined keys to help catch typos and missing values. Use config.has() to test if a configuration value is defined. Running in this configuration, the port and dbName elements of dbConfig will come from the default.json file, and the host element will come from the production.json override file. -

Custom CSS and JS
Custom CSS Plugin for Visual Studio Code. Based on vscode-icon
Custom CSS and JS is a Visual Studio Code extension that allows users to inject custom CSS and JavaScript into the editor interface, enabling deep visual and behavioral customization beyond what standard themes provide. The tool works by modifying VS Code’s internal styling system, allowing developers to override UI elements such as fonts, colors, spacing, and layout with their own stylesheets. This makes it possible to create highly personalized development environments tailored to individual preferences or workflows. In addition to aesthetic changes, users can also inject JavaScript to modify certain UI behaviors, effectively extending the editor’s functionality in unconventional ways. The extension is often used to implement custom themes, improve readability, or experiment with alternative interface designs. However, because it alters internal files, it may require reapplying changes after updates and can raise stability considerations. -

Derby
MVC framework making it easy to write collaborative applications
The Derby MVC framework makes it easy to write realtime, collaborative applications that run in both Node.js and browsers. Derby includes a powerful data synchronization engine called Racer that automatically syncs data among browsers, servers, and a database. Models subscribe to changes on specific objects, enabling granular control of data propagation without defining channels. Racer supports offline usage and conflict resolution out of the box, which greatly simplifies writing multi-user applications. Derby applications load immediately and can be indexed by search engines, because the same templates render on both server and client. In addition, templates define bindings, which instantly update the view when the model changes and vice versa. Derby makes it simple to write applications that load as fast as a search engine, are as interactive as a document editor, and work offline. -

ESLint-plugin-React
React specific linting rules for ESLint
Install ESLint either locally or globally. (Note that locally, per project, is strongly preferred). If you installed ESLint globally, you have to install React plugin globally too. Otherwise, install it locally. Use our preset to get reasonable defaults. If you are using the new JSX transform from React 17, extend react/jsx-runtime in your eslint config to disable the relevant rules. You should also specify settings that will be shared across all the plugin rules. If you do not use a preset you will need to specify individual rules and add extra configuration. This plugin exports a recommended configuration that enforces React good practices. This plugin also exports an all configuration that includes every available rule. This pairs well with the eslint:all rule. These configurations will import eslint-plugin-react and enable JSX in parser options. -

Electron Context Menu
Context menu for your Electron app
Electron Context Menu is a JavaScript package that adds configurable right-click menus to Electron applications. It provides common native-style actions that Electron developers would otherwise need to implement manually. Built-in behavior includes cut, copy, paste, text lookup, web search, link copying, image actions, video actions, and spellchecking-related commands. An Inspect Element option can automatically appear during development for easier debugging. Developers can add, remove, reorder, rename, or transform menu actions and can target specific windows or views. The package operates from Electron's main process and can apply menus to existing and newly created windows. Its extensible API helps applications provide richer context-sensitive interactions with less custom menu code. -

Email Templates
Create, preview, and send custom email templates for Node.js
Create, preview, and send custom email templates for Node.js. Highly configurable and supports automatic inline CSS, stylesheets, embedded images and fonts, and much more! Made for sending beautiful emails with Lad. We've added preview email by default to this package! If you run into any issues with configuration, files, templates, locals, etc, then you can use the DEBUG environment flag. You can swap the transport option with a Nodemailer transport configuration object or transport instance. We highly recommend using Postmark for your transport (it's the default in Lad). Out of the box, templates are cached as they are compiled (e.g. as emails are sent, the template they're using is cached). However these templates are not cached in advance, so the first emails sent of each template will be slower to send. We strongly suggest to pre-cache your templates with cache-pug-templates (if you're using the default Pug template engine). -

EpicReact.Dev
Build a ReactJS App workshop
EpicReact.Dev is the codebase used in the “Build an Epic React App” workshop, where participants build a complete React application from scratch. The project demonstrates how to structure a modern React app, including data modeling, authentication, routing, testing, and interaction with a backend. It uses a realistic “bookshelf” domain where users can manage lists of books, track reading status, and record notes, which provides a concrete context for learning. The repository includes setup scripts and system requirements checks for Git, Node, and npm, plus Docker and Codespaces options for people who struggle with local environments. A guided workflow, driven by a node go script and INSTRUCTIONS.md, lets learners move between exercises and extra credit steps while the repository updates the working files for each stage. Extensive tests, using Jest in watch mode, help students verify their solutions and learn how to work with test-driven feedback.
