history
Project history and usage
Dockerfile Language Server is Ryan C. J. Suen's TypeScript/Node.js language-server wrapper for Dockerfile editor features. It packages Dockerfile parsing, diagnostics, completion, hover, formatting, rename, document symbols, semantic highlighting, and other LSP capabilities behind the `docker-langserver` executable.
Project history
The GitHub repository was created in June 2017, soon after the Language Server Protocol had become the common way to share editor intelligence across IDEs. The README is explicit that this repository is the server launcher and LSP-facing layer, while Dockerfile analysis lives in sibling libraries such as `dockerfile-ast`, `dockerfile-language-service`, and `dockerfile-utils`.
The npm package `dockerfile-language-server-nodejs` was first published in July 2017 and reached version 0.15.0 in October 2025. GitHub releases show a v0.0.24 release in June 2020, while tags and npm metadata show later maintenance continuing through the 0.15.x line.
Adoption history
The project's adoption is more important through editor integrations than through direct command-line use. Its README lists users including Microsoft's VS Code Docker extension, Sublime LSP Dockerfile support, Zed Dockerfile support, atom-ide-docker, Sourcegraph, Theia, and Emacs lsp-mode.
Homebrew packages it as `dockerfile-language-server`, giving non-npm package-manager users a direct install path for `docker-langserver`. The Homebrew formula API reported stable version 0.15.0, 43 installs in the previous 30 days, and 1,436 installs in the previous year as of June 30, 2026.
How it is used
Users install the Node package or Homebrew formula, then run `docker-langserver` over Node IPC, stdio, or a socket so an editor or language-server client can speak LSP to it. The README also documents Docker image usage under `rcjsuen/docker-langserver`.
Why package nerds care
This package matters because it turns Dockerfile editing support into a reusable protocol server instead of one editor plugin per editor. For package managers, the interesting boundary is the small `docker-langserver` executable that bridges Homebrew, npm, Docker images, and LSP-capable editors.
