@stackra/tsup-config

Shared tsup config helper for the stackra-frontend monorepo. Every workspace package's local tsup.config.ts calls defineBaseConfig(entries, overrides?) from this package.

Usage

// packages/frontend/<pkg>/tsup.config.ts
import { defineBaseConfig } from "@stackra/tsup-config";

export default defineBaseConfig({
  index: "src/index.ts",
  react: "src/react/index.ts",
});

The base config auto-externalises anything in dependencies and peerDependencies; anything imported optionally at runtime (lazy require / await import) must be listed via the external override.

What defineBaseConfig sets

• format: ["cjs", "esm"]
• dts: true (with declaration maps)
• sourcemap: true, clean: true, treeshake: true, splitting: false
• target: "es2022"
• tsconfig: "./tsconfig.json" (per-package)
• keepNames: true (DI container uses Class.name as provider identity)
• Automatic JSX runtime for both swc and esbuild (jsx: "automatic")

Overrides

Anything the caller passes via the overrides argument wins. esbuildOptions and swc are composed instead of replaced so package-level tweaks don't blow away the JSX runtime setup.
