dprint
What it is
dprint is a free, open-source command-line application that automatically formats code. Built with Rust and WebAssembly, it uses a configurable plugin system for languages and formats such as TypeScript, JavaScript, JSON, Markdown, CSS, Python, Go, Swift, GraphQL, and YAML. Projects define plugins, formatting settings, file inclusions, and exclusions in dprint configuration files. Plugins can be loaded from a URL or file path and pinned or versioned. The project says it can format hundreds of files in milliseconds and uses incremental caching by default. WebAssembly plugins run in a sandbox without network or file-system access; process plugins are executable files and are not sandboxed. Editor integrations are listed for Visual Studio Code, IntelliJ, and Neovim, with a language-server command usable by other editors. CI options include GitHub Action, GitLab integration, and generic use through dprint check. The CLI is distributed as a static binary without runtime dependencies and can be installed through several package and tool managers. dprint is MIT-licensed and supports Windows, macOS, Linux, WSL, Node.js, and Deno.
