Dart Services

A server backend to support DartPad.

Build Status

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.

Getting set up

Initialize Flutter

The Flutter SDK needs to be downloaded and setup; check out https://flutter.dev/get-started.

Running

To run the server, run:

$ dart bin/server.dart

The server will run from port 8080 and export several JSON APIs, like /api/v3/analyze and /api/v3/compile.

Testing

To run tests:

dart test

Re-generating source

To rebuild the shelf router, run:

dart run build_runner build --delete-conflicting-outputs

Modifying supported packages

Package dependencies are pinned using the pub_dependencies_<CHANNEL>.yaml files. To make changes to the list of supported packages, you need to verify that the dependencies resolve and update the pinned versions specified in the tool/dependencies directory.

  1. Edit the lib/src/project_templates.dart file to include changes to the whitelisted list of packages.

  2. Create the Dart and Flutter projects in the project_templates/ directory:

    grind build-project-templates

  3. Run pub upgrade in the Dart or Flutter project in project_templates/

  4. Run grind update-pub-dependencies to overwrite the tool/dependencies/pub_dependencies_<CHANNEL>.yaml file for your current channel.

  5. Repeat the above steps for the latest version of each Flutter channel (main, beta and stable)

Redis

You can install and run a local redis cache. Run sudo apt-get install redis-server to install on Ubuntu or brew install redis for macOS.

See the Redis' Quick Start guide for other platforms.

To configure the server to use the local redis cache, run dart bin/server.dart with the redis-url flag.
