Welcome to Liquidart


Liquidart is an HTTP web server framework for building REST Applications written in Dart. We offer built-in support for PostgreSQL, a valuable open source database engine.

This is a revival of the Aqueduct project, which was abandoned by the StableKernel team. They did a great job with the Aqueduct package, but reached a point where they can no longer support its active development.

How to Use this Documentation

The menu on the left contains a hierarchy documents. Those documents - and how you should use them - are described in the following table:

Location Description Recommended Usage
Top-Level (e.g. Tour, Core Concepts) Introductory and quick reference documents Read these documents when you are new to Liquidart
Snippets Example code snippets of common behaviors Read these documents for examples and inspiration
Tutorial A linear, guided tutorial to building your first application A 1-3 hour long tutorial to learn Liquidart
Guides A hierarchy of in-depth guides for the many facets of Liquidart Refer to these documents often to understand concepts and usage of Liquidart

In addition to these guides, be sure to use the API Reference to look up classes, methods, functions and other elements of the framework.

Getting Started Tips

The best way to get started is to read the Core Concepts guide while working through the tutorial. Then, add new features to the application created during the tutorial by looking up the classes you are using in the API Reference, and implementing behavior not found in the tutorial.

Once you have the basic concepts down, start reading the guides in the left hand menu to take advantage of the many features of the framework. Check out the repository of examples here.

Liquidart is catered towards test-driven development - the best way to write an application is to write tests using a test harness and run those tests after implementing an endpoint. You may also run the command liquidart document client in your project directory to generate a web client for your application. This client can be opened in any browser and will execute requests against your locally running application.
