VSCodium
binary releases of VS Code without MS branding/telemetry/licensing
Microsoft’s vscode source code is open source (MIT-licensed), but the product available for download (Visual Studio Code) is licensed under this not-FLOSS license and contains telemetry/tracking. The VSCodium project exists so that you don’t have to download+build from source. This project includes special build scripts that clone Microsoft’s vscode repo, run the build commands, and upload the resulting binaries for you to GitHub releases. These binaries are licensed under the MIT license. Telemetry is disabled. If you want to build from source yourself, head over to Microsoft’s vscode repo and follow their instructions. VSCodium exists to make it easier to get the latest version of MIT-licensed VSCode. Please note that some Visual Studio Code extensions have licenses that restrict their use to the official Visual Studio Code builds and therefore do not work with VSCodium. -

Valid Swagger JSON descriptions can then be generated and used with the full Swagger tooling (code generation, documentation, etc). swagger-editor is a traditional npm module intended for use in single-page applications that are capable of resolving dependencies (via Webpack, Browserify, etc). swagger-editor-dist is a dependency-free module that includes everything you need to serve Swagger Editor in a server-side project, or a web project that can't resolve npm module dependencies. If you're building a single-page application, using swagger-editor is strongly recommended, since swagger-editor-dist is significantly larger. -

Monaco Editor
A browser based code editor
Monaco Editor is the rich, browser-based code editor that powers Visual Studio Code, providing advanced editing capabilities as a standalone embeddable library for web applications. Models are at the heart of Monaco editor. It's what you interact with when managing content. A model represents a file that has been opened. This could represent a file that exists on a file system, but it doesn't have to. For example, the model holds the text content, determines the language of the content, and tracks the edit history of the content. An editor is a user facing view of the model. This is what gets attached to the DOM and what your users see visually. Typical editor operations are displaying a model, managing the view state, or executing actions or commands. -

UIkit
Lightweight modular front-end framework for developing web interfaces
A lightweight and modular front-end framework for developing fast and powerful web interfaces. UIkit will work on pretty much any modern browser. Using UIkit works best if you have a solid code editor, for example Sublime Text or Atom. To be even more efficient, we recommend that you install one of the autocomplete plugins for your favorite IDE or code editor. This saves a lot of time, as you won't have to look up and type all UIkit classes and markup. To use UIkit's CSS and JavaScript, include the files in your own HTML and then create the markup of any of the components. When you have installed UIkit with Less sources, you can compile it and add your own custom theme. Less is the language that the UIkit styles are written in. This allows you to include customizations in the build process, rather than manually overwriting a lot of CSS rules by hand. -
