prettier-plugin-elm

Adds Elm language support to Prettier by wrapping elm-format. Version 0.12.0 (2025-09-21) requires Node >=18.20.6 and uses elm-format 0.8.8. Works with Prettier v2 (global) or v3 (local with explicit plugin config). Formats .elm files and Elm code blocks inside Markdown documents, with support for <!-- prettier-ignore -->. Key differentiators: integrates elm-format directly into the Prettier ecosystem, handles both standalone files and embedded code blocks. Vendors elm-format internally, reducing version conflicts. Designed for Elm 0.19; older plugin versions support Elm 0.18. Maintained by giCentre, with TypeScript source code.
