hot

Supports hot reloading of Angel servers on file changes. This is faster andmore reliable than merely reactively restarting a Process.

This package only works with the Angel framework.

Installation

In your pubspec.yaml:

1. dependencies:
2. angel_framework: ^2.0.0-alpha
3. angel_hot: ^2.0.0

Usage

This package is dependent on the Dart VM service, so you must runDart with the —observe (or —enable-vm-service) argument!!!

Usage is fairly simple. Pass a function that creates an Angel server, along with a collection of pathsto watch, to the HotReloader constructor. The rest is history!!!

The recommended pattern is to only use hot-reloading in your application entry point. Create your Angel instancewithin a separate function, conventionally named createServer.

Using this in production mode is not recommended, unless you arespecifically intending for a "hot code push" in production..
