netlify-config

Reference for netlify.toml configuration and site environment variables. Use when configuring build settings, redirects, rewrites, headers, deploy contexts, the [dev] block that controls netlify dev (command, port, targetPort, framework), or any site-level configuration — and when managing environment variables or secrets with the Netlify CLI, including scoping values to specific deploy contexts. Covers the complete netlify.toml syntax including redirects with splats/conditions, headers, deploy contexts, functions config, edge functions config, and the [dev] block (including when framework must be "#custom" — required when both a custom command and targetPort are set).
