What this trail covers

Vercel's platform allows configuring environment variables for Production, Preview, and Development environments directly through the Dashboard. The Vercel CLI provides commands like `vercel env pull` to download Development Environment Variables locally into a `.env` file, and `vercel env add`/`remove` for command-line management. System environment variables provided by the platform are also configurable.

All Vercel trails
  1. Environment Variables UIIntroduced a new Environment Variables section in Project Settings to configure distinct variables for Production, Preview, and Development environments without requiring `vercel.json`. Added `vercel env pull` command to the CLI for downloading Development Environment Variables locally, creating a `.env` file. Introduced `vercel env add` and `vercel env remove` for command-line management of environment variables.
  2. Advanced Project Settings on VercelIntroduced the ability to specify a Root Directory when connecting Git repositories, select a Framework or overwrite its default settings during import, and fully customize project settings (Build Command, Development Command, Output Directory) from the Project Settings page. Also enabled creating new projects via the Vercel CLI with on-the-fly configuration editing and linking local codebases to existing projects.
  3. Configuring FunctionsThis post details how to configure environment variables for Vercel Functions across different environments (Production, Preview, Development) using the Vercel Dashboard and CLI. It explains how to pull development environment variables locally into a `.env` file and manage them via command-line arguments. It also mentions configurable system environment variables provided by the platform.
