Vite Config Generator

Generate Vite config files for React, Vue, TypeScript, aliases, server proxy, modes, testing, plugins, PWA, and Rollup options.

Output:A ready-to-use configuration file for Vite Config with best practices applied.

Quick Summary

Use a Vite Config Generator when you need config files for Vite projects with aliases, plugins, server proxy options, environment modes, and Rollup build settings for React, Vue, or Svelte.

What is this tool?

A Vite Config Generator is an interactive tool that scaffolds the configuration file (vite.config.ts or vite.config.js) used by the Vite build tool. Vite is a next-generation frontend tooling solution that provides extremely fast hot module replacement (HMR) during development and highly optimized Rollup builds for production.

This generator takes the guesswork out of configuring the vite config server, setting up the vite proxy config, managing vite resolve aliases, and integrating framework-specific plugins for React or Vue.

How to Use This Tool

Select Framework — Choose React, Vue, Svelte, or Vanilla JavaScript.
Configure Language — Select TypeScript to generate a vite.config.ts file, or JavaScript for vite.config.js.
Set Server Options — Define your development port and configure API proxies to bypass CORS.
Define Build Options — Set the base URL for deployment and configure the output directory.
Download — Save the generated config file in the root directory of your Vite project.

What This Tool Generates

vite.config.ts — The type-safe configuration file for TypeScript projects.
vite.config.js — The standard configuration file for JavaScript projects.
.env.example (Optional) — Example environment variables for Vite's import.meta.env system.

Example Output Explanation

A standard vite config js example configured for a React app with a backend API proxy and path aliases:

import { defineConfig } from 'vite';
import react from '@vitejs/plugin-react';
import tsconfigPaths from 'vite-tsconfig-paths';

export default defineConfig({
  plugins: [react(), tsconfigPaths()],
  server: {
    port: 3000,
    open: true,
    proxy: {
      '/api': {
        target: 'http://localhost:8080',
        changeOrigin: true,
        secure: false,
      },
    },
  },
  build: {
    outDir: 'dist',
    sourcemap: false,
  },
});

Best Practices

Use TypeScript: Always generate a vite.config.ts file instead of .js. Vite automatically compiles it, and you get strict autocomplete via the `defineConfig` helper.
Use vite-tsconfig-paths: Instead of manually duplicating your path aliases inside `resolve.alias` in Vite, use the `vite-tsconfig-paths` plugin to automatically sync them from your tsconfig.json.
Proxy API Calls: Use the `server.proxy` configuration in Vite to route local frontend API calls to your local backend server, completely bypassing CORS issues during development.
Environment Variables: Vite only exposes environment variables prefixed with `VITE_` to your client-side code. Never put secret keys (like database passwords) in variables starting with `VITE_`.

Common Mistakes

Missing Framework Plugin: If you don't add `@vitejs/plugin-react` or `@vitejs/plugin-vue` to your plugins array, Vite will not understand JSX or Vue templates and will crash.
Hardcoding Base URLs: If you are deploying to a subdirectory (like GitHub Pages), you must set the `base` property in the config (e.g., `base: '/subpath/'`). Forgetting this causes 404 errors for all JS and CSS assets.
Trying to use `process.env` in the browser: Vite does not polyfill `process.env`. You must use `import.meta.env.VITE_YOUR_VARIABLE` to access environment variables in your frontend code.

Security Notes

Never commit your `.env` file to version control. Generate a `.env.example` file to show developers what variables are needed.
Review any third-party Vite plugins you install. Since they run in a Node.js context during the build process, malicious plugins can access your file system and environment variables.

Testing Instructions

Save the generated file as `vite.config.ts` in your project root.
Install any required plugins listed in the import statements (e.g., `npm i -D @vitejs/plugin-react`).
Run `npm run dev` (which executes `vite`) to start the development server and verify the configuration.

Frequently Asked Questions

What is a Vite Config Generator?

A Vite Config Generator is a visual tool that scaffolds a vite.config.js (or .ts) file for you. It allows you to select plugins (like React or Vue), configure path aliases, set up API proxies, and tweak Rollup build options without needing to manually write the configuration.

How do I create vite.config.js?

You can create a vite.config.js file in the root of your project by exporting a configuration object using `defineConfig()`. Alternatively, use this generator to select your framework and server settings, and download the pre-configured file.

Should I use vite.config.js or vite.config.ts?

If you are working in a TypeScript project, you should definitely use `vite.config.ts`. Vite natively understands and compiles TypeScript configuration files out of the box, providing excellent autocomplete and type safety.

How do I configure Vite server?

You can configure the development server by adding a `server` object to your Vite config. This allows you to set the `port` (e.g., 3000), enable `strictPort`, automatically `open` the browser, or set up a `proxy` to bypass CORS issues when calling your backend API.

How do I use tsconfig paths in Vite?

To make Vite understand the path aliases (like `@/components`) defined in your tsconfig.json, you must install and use the `vite-tsconfig-paths` plugin. Add it to the `plugins` array in your vite.config.ts.

How do I configure Vite for React?

Install `@vitejs/plugin-react` (or `@vitejs/plugin-react-swc` for faster SWC compilation) and add it to the `plugins` array in your vite.config.js. This enables Fast Refresh and JSX transformation.

How do I configure Vite for Vue?

Install `@vitejs/plugin-vue` and add it to your `plugins` array. This is required for Vite to understand and compile Single-File Components (.vue files).

What are Rollup options in Vite?

Under the hood, Vite uses Rollup for its production build. You can pass Rollup-specific settings directly into the Vite config via the `build.rollupOptions` object to customize things like external dependencies or output chunk naming.

How We Keep Your Configs Safe & Valid

Built-in Error Checking

Every file is checked against official rules. We catch missing fields and bad syntax. YAML indentation errors are flagged right away. Kubernetes, Terraform, and Docker specs are all covered. API versions and labels are verified too. You get valid output every time you generate.

100% Private & Local

All tools run in your browser only. Your API keys never leave your machine. We do not use any tracking scripts. No data is sent to any server. Passwords and secrets stay on your device. Crypto operations use the Web Crypto API. Your privacy is fully protected at all times.

Secure Settings by Default

Configs use safe defaults out of the box. Containers run as non-root users. Root filesystems are set to read-only. Dangerous Linux capabilities are dropped. Network policies limit pod-to-pod traffic. TLS 1.3 is enabled for web servers. Security headers are added where needed.

Ready for CI/CD & Git

Output files are ready for your Git repo. Use them with ArgoCD, Flux, or GitHub Actions. Files use clear formatting and comments. Code review is easy for your team. Indentation and key order are consistent. Test in staging before going to production. Every file is clean and well-structured.

Infrastructure as Code

Store configs in Git alongside your code. Terraform modules include typed variables. Backend configs support remote state locking. Outputs work across multiple modules. Ansible playbooks use clear task steps. Chef and Puppet configs are also supported. Every file works with version control tools.

Monitoring & Tracing

Set up Prometheus with auto-discovery rules. Create Grafana dashboards with template variables. Add alerting rules with severity labels. Use OpenTelemetry for trace collection. Forward logs to Loki or Elasticsearch. Connect to Jaeger or Tempo for tracing. Monitor metrics, logs, and traces together.

Container & Docker Safety

Dockerfiles use multi-stage builds for small images. Base images are pinned to exact versions. Dev files are excluded from final images. Health checks are added for orchestrator use. Containers switch to non-root users. Docker Compose uses named volumes and networks. Resource limits are set in deploy configs.

Multiple Output Formats

Export as YAML, JSON, HCL, or TOML. Kubernetes uses YAML with proper separators. Terraform uses HCL with correct escaping. JSON output has consistent indentation. Copy to clipboard with one click. Preview output with syntax highlighting. Line numbers help you review quickly.
