What is Environment Variables in Next JS?
Next.js is equipped with native support for managing environment variables, providing the following capabilities:
- Utilize .env.local for loading environment variables.
- Expose environment variables to the browser by prefixing them with NEXT_PUBLIC_.
- Default Environment Variables: Typically, only one .env.local file is required. However, there may be instances where you want to establish defaults specifically for the development (next dev) or production (next start) environment.
- Next JS enables you to define defaults in .env (applicable to all environments), .env.development (specific to the development environment), and .env.production (specific to the production environment).
- It’s important to note that .env.local always takes precedence over any defaults that are set.
