- A bundler to support hot module replacement in development and bundle your code for production, we support both [webpack 5](https://webpack.js.org/) and [Vite](https://vitejs.dev/).
- A server for serving your application in development, but also to support [server-side rendering](https://vuejs.org/api/ssr.html#server-side-rendering-api) or API routes, Nuxt uses [h3](https://github.com/unjs/h3) for deployment versatility such as serverless, workers, Node.js and unmatched performance.
- A routing library to handle client-side navigation, we chose [vue-router](https://router.vuejs.org/).
This is only the tip of the iceberg, imagine having to set up all of this for your project, make it work, and then, maintain it over time. We have been doing this since October 2016, tuning all the configurations to provide the best optimization and performance for any Vue application.
On top of this setup, Nuxt provides a [directory structure](/guide/directory-structure) to follow, focused on specific features to keep your focus on creating, not configuring.
- Bundlers: [@nuxt/vite-builder](https://github.com/nuxt/framework/tree/main/packages/vite) and [@nuxt/webpack-builder](https://github.com/nuxt/framework/tree/main/packages/webpack)
- Command line interface: [nuxi](https://github.com/nuxt/framework/tree/main/packages/nuxi)
Extendable with a strong module ecosystem and hooks engine, it makes it easy to connect your REST or GraphQL endpoints, favorite CMS, CSS frameworks and more. PWA and AMP support is only a module away from your Nuxt project.
Take a stab at an open [issue](https://github.com/nuxt/framework/issues). This is the best way to learn Nuxt, by actually diving into the code. You may even bring an approach or alternative solution that makes Nuxt even better! So, what are you waiting for? Let's go!
