flake.nix only rewrote @/ aliases but left extensionless relative imports (./router) in compiled dist/. node dist/index.js (how prod runs) cannot resolve extensionless ESM specifiers -> ERR_MODULE_NOT_FOUND -> backend crashlooped (444 restarts, port 4001 dead). Extract the fixer into a shared scripts/fix-imports.mjs that appends .js to extensionless relative imports and rewrites @/ aliases, and wire it into backend + discord-gateway build phases. Verified: fresh tsc + fixer -> node dist/index.js boots; oRPC over /trpc serves both HTTP POST and WebSocket (config/dashboard/voice/moderation/ media/chatbot/analysis) end-to-end against Postgres + Redis. next build passes with the oRPC client + partysocket.

// Rewrite import specifiers in the compiled dist/ so the output runs under
|
|
// plain `node dist/index.js` (native ESM, no bundler / no tsx).
|
|
//
|
|
// Background: tsconfig uses moduleResolution:"bundler", so `tsc` emits BARE
|
|
// relative specifiers WITHOUT extensions (e.g. `import "./router"`) and leaves
|
|
// the `@/*` path-alias imports untouched. Node's native ESM resolver rejects
|
|
// extensionless relative specifiers and knows nothing about the `@/` alias, so
|
|
// the emitted dist/ crashes at startup (`ERR_MODULE_NOT_FOUND`). This script
|
|
// fixes both:
|
|
// 1. `@/foo` -> relative path to dist/foo.js
|
|
// 2. `./foo` / `../foo` -> `./foo.js` / `../foo.js` (append .js)
|
|
// Already-extensioned relative imports (.js/.json/.node/.mjs/.cjs) and bare
|
|
// package specifiers are left untouched (idempotent).
