Pendulum Editor
A simple markdown editor for static files (Hugo, Nexo, Jekyll
A simple editor for markdown/txt files. Supports saving changes into git repositories hosted anywhere (git add, git commit). Docker images and built binaries are provided. Written by @TitPetric and licensed under the permissive WTFPL. As you write or scroll either the text area or the preview pane, the scroll positions are synchronized based on percentage. In the case of images in the text, accuracy can be quite off, but it's possible to improve this behavior in the future. Most of the development is basically related to the preview of whatever it is you're editing. The editor itself doesn't care about anything other than the contents of the text file you're opening and trying to save. -

Polymer
A Web Component library
Polymer is a lightweight Web Components library that lets you create encapsulated Web Components that work just like standard HTML elements. These elements can be used in building web applications and are reusable. Polymer can be particularly useful when building UI components. Instead of having to constantly rebuild components such as a specific navigation bar or button in different frameworks and for different projects, simply define this component once with Polymer, and you can use it again and again in your future projects. Because Polymer is built on top of the web standards-based Web Components APIs, custom HTML elements made from it are built totally from the platform up and are interoperable across frameworks. Polymer also works across all major browsers. -

Puck
Open source visual editor for building React drag-and-drop pages
Puck is an open source visual editor designed for React applications that enables developers to build customizable drag-and-drop page editing experiences. It allows teams to create their own page builders by defining React components that can be arranged and configured through a visual interface. Puck is component-based and configuration-driven, meaning developers specify how components render and which editable fields control their properties. Puck integrates directly into existing React environments and works well with frameworks such as Next.js, enabling developers to embed editing capabilities directly inside their applications. It operates with a structured data model that stores content as a JSON payload, allowing the same configuration to power both the editing interface and the production rendering of pages. This approach gives developers full ownership of their content data while avoiding vendor lock-in. -

React Redux
React bindings for Redux
React Redux is the official React binding for Redux. It lets your React components read data from a Redux store, and dispatch actions to the store to update data. React Redux is maintained by the Redux team, and kept up-to-date with the latest APIs from Redux and React. Designed to work with React's component model. You define how to extract the values your component needs from Redux, and your component receives them as props. Creates wrapper components that manage the store interaction logic for you, so you don't have to write it yourself. Automatically implements complex performance optimizations, so that your own component only re-renders when the data it needs has actually changed. Redux itself is a standalone library that can be used with any UI layer or framework, including React, Angular, Vue, Ember, and vanilla JS. Although Redux and React are commonly used together, they are independent of each other. -

Redux-ORM
A small, simple and immutable ORM to manage relational data
A small, simple and immutable ORM to manage relational data in your Redux store. Redux-ORM is fast. All queries are lazily evaluated and come with built-in support for memorization. It provides a clean abstraction over low-level updates, protecting the state from accidental mutations. With nearly 100% branch coverage, the library is thoroughly tested to ensure rock-solid code quality. No matter where your data comes from, Redux-ORM will stay out of its way. Even a custom database layer is possible. Defining fields on a Model specifies the table structure in the database for that Model. In order to generate a description of the whole database's structure, we need a central place to register all Models we want to use. An instance of the ORM class registers Models and handles generating a full schema from all the models and passing that information to the database. Often you'll want to have a file where you can import a single ORM instance across the app. -

Relay
JavaScript framework for building data-driven React applications
Relay is data-fetching turned declarative. Components declare their data dependencies, without worrying about how to fetch them. Relay guarantees that the data each component needs is fetched and available. This keeps components decoupled and promotes reuse. With Relay, components and their data dependencies can be quickly modified without modifying other parts of the system. That means you won't accidentally break other components as you refactor or make changes to your app. Relay's compiler aggregates and optimizes the data requirements for your entire app, so that they can be efficiently fetched in a single GraphQL request. Relay handles the heavy lifting to ensure the data declared by your components is fetched in the most efficient way. For example, by deduplicating identical fields, and precomputing information used at runtime, among other optimizations. Relay also supports executing GraphQL Mutations, optionally with optimistic updates, and updates to local data. -

A tool for responsive web design, allowing developers to preview websites across multiple screen sizes. -
19
Rollup
A module bundler for JavaScript
Rollup is a module bundler for JavaScript which compiles small pieces of code into something larger and more complex, such as a library or application. It uses the new standardized format for code modules included in the ES6 revision of JavaScript, instead of previous idiosyncratic solutions such as CommonJS and AMD. ES modules let you freely and seamlessly combine the most useful individual functions from your favorite libraries. This will eventually be possible natively everywhere, but Rollup lets you do it today. Rollup can be used either through a command line interface with an optional configuration file, or else through its JavaScript API. Rollup allows you to write your code using the new module system, and will then compile it back down to existing supported formats such as CommonJS modules, AMD modules, and IIFE-style scripts. This means that you get to write future-proof code. -

RuoYi
The warehouse's SpringBoot-based rights management system
The warehouse's SpringBoot-based rights management system is easy to read and understand, and the interface is simple and beautiful. The core technology uses Spring, MyBatis, and Shiro without any other heavy dependencies. I have always wanted to make a background management system, and I have seen many excellent open source projects but found no suitable ones. So I started to write a background system in my spare time. So there is Zoe. She can be used for all web applications, such as website management background, website member center, CMS, CRM, OA. All front-end and back-end codes are very compact and easy to use after encapsulation, and the probability of errors is low. Also supports mobile client access. The system will continue to update some useful functions. The user is the system operator, and this function mainly completes the system user configuration. Configure the system organization (company, department, group). -

Serverless Offline
Emulate AWS λ and API Gateway locally
This Serverless plugin emulates AWS λ and API Gateway on your local machine to speed up your development cycles. To do so, it starts an HTTP server that handles the request's lifecycle like APIG does and invokes your handlers. Options passed on the command line override YAML options. List of available function names and their corresponding serverless.yml function keys are listed after the server starts. This is important if you use a custom naming scheme for your functions as serverless-offline will use your custom name. The left side is the function's key in your serverless.yml and the right side is the function name that is used to call the function externally such as aws-sdk. Once you run a function that boots up the Docker container, it'll look through the layers for that function, download them in order to your layers folder, and save a hash of your layers so it can be re-used in future. -

25
ShellJS
Portable Unix shell commands for Node.js
ShellJS is a portable (Windows/Linux/macOS) implementation of Unix shell commands on top of the Node.js API. You can use it to eliminate your shell script's dependency on Unix while still keeping its familiar and powerful commands. You can also install it globally so you can run it from outside Node projects, say goodbye to those gnarly Bash scripts! ShellJS is proudly tested on every node release since v8! ShellJS now supports third-party plugins! You can learn more about using plugins and writing your own ShellJS commands in the wiki. The most important thing is to require the most recent version of ShellJS as a peer-dependency. If you want to add unit tests for your plugin as well, you'll probably want it as a dev-dependency too.
