What is it? What does it do?

This project is a small, stateless Dart server, which powers the front-end of DartPad. It provides many of DartPad's features, including static analysis (errors and warnings), compilation to JavaScript, code completion, dartdoc information, code formatting, and quick fixes for issues.


To run the server, run:

dart bin/server_dev.dart --port 8082

The server will run from port 8082 and export several JSON APIs, like /api/compile and /api/analyze.


To deploy the server to Dart on AppEngine, follow the instructions here.

Modify warmup.dart to point the BASE_URI to your AppEngine project.

Then run


The will deploy the server, and run the warmup sequence and sanity checks.
