{"id":22944,"library":"vite-shield","title":"Vite-Shield","description":"Vite-Shield is a zero-configuration CLI tool that automatically adds comprehensive security headers to Vite/React projects. Version 1.0.0 integrates security headers into Vite's dev and preview servers, generates a production-ready Express.js server with helmet-style headers, and creates an Nginx configuration template. Unlike manual header setup or using helmet separately, Vite-Shield provides a one-command solution using AST-based transformations to safely modify vite.config.ts/js without breaking existing setups. It applies headers like Strict-Transport-Security, CSP, X-Frame-Options, and more across all environments.","status":"active","version":"1.0.0","language":"javascript","source_language":"en","source_url":"https://github.com/Power70/vite-shield","tags":["javascript","vite","react","security","headers","csp","content-security-policy","helmet","express"],"install":[{"cmd":"npm install vite-shield","lang":"bash","label":"npm"},{"cmd":"yarn add vite-shield","lang":"bash","label":"yarn"},{"cmd":"pnpm add vite-shield","lang":"bash","label":"pnpm"}],"dependencies":[{"reason":"required to modify vite.config file and apply headers","package":"vite","optional":false}],"imports":[{"note":"CLI tool only, no programmatic API available","wrong":"import viteShield from 'vite-shield'","symbol":"vite-shield","correct":"npx vite-shield"},{"note":"Vite config must use ESM export syntax","wrong":"module.exports = { server: { headers: {} } }","symbol":"vite.config","correct":"export default defineConfig({ server: { headers: {} } })"}],"quickstart":{"code":"# Navigate to your Vite/React project\ncd my-vite-project\n\n# Install vite-shield globally or use npx\nnpm install -g vite-shield\nvite-shield\n\n# Alternatively, with npx (no install):\nnpx vite-shield\n\n# After running, vite.config.ts/js is updated with security headers.\n# A production server.js and nginx.conf are also created.\n# To start the production server:\nnpm install --save-dev express\nnode server.js\n","lang":"javascript","description":"Shows how to install and run vite-shield via global install or npx, then start the generated Express server."},"warnings":[{"fix":"Manually back up your vite.config before running vite-shield","message":"Running vite-shield overwrites any existing security headers in vite.config.ts/js without merging","severity":"gotcha","affected_versions":">=1.0.0"},{"fix":"Review the generated config and manually adjust if needed","message":"vite-shield modifies vite.config.ts/js using AST; if your config uses unusual syntax or plugins that generate dynamic headers, the tool may produce invalid config","severity":"gotcha","affected_versions":">=1.0.0"},{"fix":"Add \"type\": \"module\" to package.json or rename server.js to server.mjs","message":"The generated server.js uses ESM imports (import express from 'express') which requires \"type\": \"module\" in package.json or .mjs extension","severity":"gotcha","affected_versions":">=1.0.0"},{"fix":"Ensure the add_header directives are inside the server block and not duplicated","message":"The generated nginx.conf uses add_header directives that may conflict with existing server blocks if not placed in the correct context","severity":"gotcha","affected_versions":">=1.0.0"}],"env_vars":null,"last_verified":"2026-04-27T00:00:00.000Z","next_check":"2026-07-26T00:00:00.000Z","problems":[{"fix":"Use npx vite-shield or npm install -g vite-shield","cause":"vite-shield not installed globally or path not set","error":"Command 'vite-shield' not found"},{"fix":"cd to the directory containing vite.config.ts or vite.config.js before running","cause":"Command not run from the root of a Vite project","error":"Cannot find module '/path/to/project/vite.config.ts'"},{"fix":"Run vite-shield with no arguments","cause":"vite-shield has no CLI options; extra flags cause errors","error":"error: unknown option '--something'"}],"ecosystem":"npm","meta_description":null,"install_score":null,"install_tag":null,"quickstart_score":null,"quickstart_tag":null}
