environment-variables

# Environment Variables This is how we add environment variables to the project: 1. Add to `.env.example`: ```bash NEW_VARIABLE=value_example ``` 2. Add to `apps/web/env.ts`: ```typescript // For server-only variables server: { NEW_VARIABLE: z.string(), } // For client-side variables client: { NEXT_PUBLIC_NEW_VARIABLE: z.string(), } experimental__runtimeEnv: { NEXT_PUBLIC_NEW_VARIABLE: process.env.NEXT_PUBLIC_NEW_VARIABLE, } ``` 3. For client-side variables: - Must be prefixed with `NEXT_PUBLIC_` - Add to both `client` and `experimental__runtimeEnv` sections 4. Add to `turbo.json` under `globalDependencies`: ```json { "tasks": { "build": { "env": [ "NEW_VARIABLE" ] } } } ``` examples: - input: | # Adding a server-side API key # .env.example API_KEY=your_api_key_here # env.ts server: { API_KEY: z.string(), } # turbo.json "build": { "env": ["API_KEY"] } output: "Server-side environment variable properly added" - input: | # Adding a client-side feature flag # .env.example NEXT_PUBLIC_FEATURE_ENABLED=false # env.ts client: { NEXT_PUBLIC_FEATURE_ENABLED: z.coerce.boolean().default(false), }, experimental__runtimeEnv: { NEXT_PUBLIC_FEATURE_ENABLED: process.env.NEXT_PUBLIC_FEATURE_ENABLED, } # turbo.json "build": { "env": ["NEXT_PUBLIC_FEATURE_ENABLED"] } output: "Client-side environment variable properly added" references: - apps/web/env.ts - apps/web/.env.example - turbo.json
