@assistant-ui/x-buildutils

This package is an internal dependency of assistant-ui and does not follow semantic versioning. If you are not working inside this monorepo, you should use your own build pipeline instead.

What it provides

• aui-build CLI: invoked as "build": "aui-build" from every package's package.json. Compiles TypeScript with our shared strict config, validates that imports resolve to declared exports sub-paths, and rewrites .ts import specifiers to .js so the emitted ESM works at runtime. Declarations come from one TypeScript program over the whole package (a TypeScript API pass after the JavaScript build for ESM packages, tsdown's declaration build mode for CommonJS ones), so two builds of the same commit produce the same .d.ts. A /// <reference> directive in an entry file carries preserve="true", since the declaration emitter drops every other directive; either build fails on one without it.
• ts/: shared tsconfig fragments (base.json, base-node.json, next.json, and test.json for a package's colocated vitest suites, which run under Node).
• types/: shared ambient types (e.g. browser-process).
