Environment Variable Configuration

Convention

All env access MUST go through centralized config modules — never read process.env or import.meta.env directly in application code.

Package	Config file	Access method
server	apps/server/src/config.ts	process.env with defaults
client	apps/web/src/config.ts	import.meta.env (Vite)

Server Config (apps/server/src/config.ts)

export const config = {
  port: Number(process.env.PORT ?? 3000),
  databaseUrl: process.env.DATABASE_URL,
  rawStore: {
    drivers: parseRawStoreDrivers(process.env.RAW_STORE ?? ''),
    sqlitePath: process.env.RAW_STORE_SQLITE_PATH ?? './data/code-quest.db',
    fileDir: process.env.RAW_STORE_FILE_DIR ?? './data/events',
  },
  systemPrompt: process.env.SYSTEM_PROMPT ?? '',
  allowDangerouslySkipPermissions: process.env.ALLOW_DANGEROUSLY_SKIP_PERMISSIONS !== 'false',
};

Env loading: Node.js 20+ native --env-file flag (no dotenv dependency).

"dev": "tsx watch --env-file=.env src/bin/server.ts"

Client Config (apps/web/src/config.ts)

export const config = {
  serverUrl: (import.meta.env.VITE_SERVER_URL as string) || '',
};

Vite auto-loads .env files. Only VITE_ prefixed vars are exposed to client.

.env Files

File	Location
Server	apps/server/.env
Server example	apps/server/.env.example
Client	apps/web/.env
Client example	apps/web/.env.example

Adding a New Env Var

1. Add to the appropriate config module (config.ts) with a sensible default
2. Add to .env.example with a comment
3. If server-side, no prefix needed. If client-side, use VITE_ prefix
4. No zod validation currently — just raw access with defaults
5. Import config in application code, never access env directly

Notes

• parseRawStoreDrivers() parses comma-separated driver list (e.g., 'sqlite,mysql,file')
• allowDangerouslySkipPermissions defaults to true (only 'false' disables it)
• Dev proxy configured in apps/web/vite.config.ts using process.env.PORT
• Test: apps/server/src/__tests__/config.test.ts (covers parseRawStoreDrivers)
