Getting Started

What is Lithia.js?

Lithia.js is a Node.js framework for building server-side applications with file-based routing and a built-in development UI.

Inspired by the simplicity and power of Next.js, Lithia.js automatically converts your file structure into API routes, making it easy to build REST APIs.

Unlike other server-side Node.js frameworks, Lithia.js does not require any configuration, entry files, or decorators. All lower-level functionality is handled automatically, so you can focus on building your application.

Go ahead with this documentation to get started with your first application.

How to use the docs

The docs are structure into these sections:

• Introduction - This section helps you understand the basics of Lithia.js, and how to install and use it.
• Core Concepts - The core functionality of Lithia.js, like routing, middlewares, how request and response works and more.

Pre-requisite knowledge

Before you start, you'll need to know the following:

• Node.js 20+ installed
• Basic TypeScript knowledge (types are helpful but optional)
• Familiarity with REST APIs (HTTP methods, status codes)

If you're new to Node.js, don't worry, we'll cover the basics in the introduction section.
