• -rw-r--r-- The TypeScript build ecosystem Concept 2026-08-10

  The layered TypeScript toolchain — runtimes, package managers, compilers, bundlers — across the frontend and backend worlds, and the artifact formats they produce.

• -rw-r--r-- The bundler world Concept 2026-08-10

  One registry, four clients — semver ranges and lockfiles, node_modules layouts from hoisted flat trees to pnpm's symlinked store, workspaces, Corepack pinning, and the lifecycle-script supply chain.
