@ts-refinement/typescript-plugin

The official TypeScript language-service plugin for ts-refinement diagnostics.

npm install ts-refinement
npm install --save-dev @ts-refinement/typescript-plugin typescript

{
  "compilerOptions": {
    "plugins": [
      {
        "name": "@ts-refinement/typescript-plugin"
      }
    ]
  }
}

The shared analyzer is bundled into this CommonJS package so tsserver can load it without crossing an ESM/CommonJS package boundary.

This package provides editor diagnostics and the ts-patch Program Transformer for TypeScript 5.7 through 6.x. Use tspc --noEmit in CI, a supported unplugin adapter for runtime transforms, and ts-refinement verify from prepack. RF1000500 is reported as a warning when a publishable package exposes refinements without configured verification.

See the repository README for editor setup and supported diagnostics.
