Run golar type checking and type-aware linting alongside your Rsbuild build, in a separate process.

Because golar is built on typescript-go and understands embedded languages, type errors inside .vue, .svelte, .astro and .gts files are reported at their real position in the source file.

pnpm add -D @golar-rstack/rsbuild golar

Create golar.config.ts in your project root. golar discovers it relative to its working directory:

import { defineConfig } from 'golar/unstable'
import '@golar/vue'

export default defineConfig({})

// rsbuild.config.ts
import { pluginGolar } from '@golar-rstack/rsbuild'
import { defineConfig } from '@rsbuild/core'
import { pluginVue } from '@rsbuild/plugin-vue'

export default defineConfig({
  plugins: [pluginVue(), pluginGolar()],
})

In dev the check runs asynchronously so it never delays HMR; results land in the terminal and the browser error overlay. In build the compilation waits for golar, so type errors fail the build.

See the repository README for the full list. Two worth knowing up front:

• lintSeverity defaults to 'warning', because golar exits 0 when only lint rules fire.
• cwd defaults to Rsbuild's rootPath and is what selects the golar config, since golar has no --config flag.

• Node.js >= 22.12
• golar installed in the project
