# Replit Install & Auth ## Overview Set up a Replit App from scratch: configure `.replit` and `replit.nix`, manage Secrets (AES-256 encrypted environment variables), and integrate Replit Auth for zero-setup user authentication with Google, GitHub, Apple, X, and Email login. ## Prerequisites - Replit account (Free, Core, or Teams plan) - Replit App created from template, GitHub import, or blank - For Auth: deployed app on `.replit.app` or custom domain ## Instructions ### Step 1: Configure `.replit` File ```toml # .replit — controls run behavior, deployment, and environment entrypoint = "index.ts" run = "npm start" # Nix modules provide language runtimes modules = ["nodejs-20:v8-20230920-bd784b9"] [nix] channel = "stable-24_05" [env] NODE_ENV = "development" PORT = "3000" [deployment] run = ["sh", "-c", "npm start"] deploymentTarget = "autoscale" build = ["sh", "-c", "npm run build"] ignorePorts = [3001] [unitTest] language = "nodejs" [packager] language = "nodejs" [packager.features] packageSearch = true guessImports = true [gitHubImport] requiredFiles = [".replit", "replit.nix"] ``` ### Step 2: Configure `replit.nix` ```nix # replit.nix — system-level dependencies via Nix { pkgs }: { deps = [ pkgs.nodejs-20_x pkgs.nodePackages.typescript-language-server pkgs.nodePackages.pnpm pkgs.postgresql pkgs.python311 pkgs.python311Packages.pip ]; } ``` After editing `replit.nix`, reload the shell for changes to take effect. ### Step 3: Co...
