srid TypeScript + Nix (pnpm)
Dependency hash management
nix/modules/typescript.nix uses fetchPnpmDeps with a pinned hash. When pnpm-lock.yaml changes (via pnpm add/remove/update), this hash goes stale and nix build fails.
Fix recipe
- Run
nix build 2>&1— it fails with a hash mismatch - Extract the correct hash from the
got: sha256-...line in the error - Update the
hash = "sha256-..."line innix/modules/typescript.nix
Parallelization
Run the hash fix in background immediately after pnpm-lock.yaml changes. Don't wait until end of session — kick it off as soon as the lock file is modified, then continue coding. The nix build takes minutes; doing it in background avoids blocking other work.
Build
nix build— full production build (client + server bundle)nix run— build and run- Client is built with
pnpm --filter kolu-client build(Vite) - Server runs via
tsx(TypeScript execution without compile step)
