angel_hot 1.1.1

Supports hot reloading of Angel servers on file changes.

hot

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

This package only works with the Angel framework.

Installation

In your pubspec.yaml:

dependencies:
  angel_hot: ^1.0.0

Usage

This package is dependent on the Dart VM service, so you must run Dart with the --enable-vm-service argument!!!

Usage is fairly simple. Pass a function that creates an Angel server, along with a collection of paths to 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 instance within a separate function, conventionally named createServer. Using this in production mode is pointless.

You can watch:

• Files
• Directories
• Globs
• URI's
• package: URI's
