vite-plugin-checker/dist/checkers/tscUtils.d.ts

Vite plugin that runs TypeScript type checker on a separate process.

import ts from "typescript";

//#region src/checkers/tscUtils.d.ts
/**
 * Wrap a `SolutionBuilderWithWatchHost` so that when a referenced project's
 * tsconfig fails to parse, we force `compilerOptions.noEmit` to `true` instead
 * of letting TS fall back to defaults (which include `noEmit: false`).
 *
 * `createSolutionBuilderWithWatch` takes its emit decisions from each referenced
 * project's own `compilerOptions`. If a referenced tsconfig is truncated or
 * mid-write at the moment TS reads it (which can happen e.g. when a dev tool
 * rewrites tsconfigs at runtime), TS falls back to default options — and the
 * default is `noEmit: false`, so the build host writes `.js` files next to
 * sources. See https://github.com/nuxt/nuxt/issues/32872.
 *
 * We deliberately only override when parsing produced errors: forcing
 * `noEmit: true` on every parsed project would break valid `tsc --build`
 * graphs, since composite referenced projects must emit declarations.
