# Usage
|
||||
This package is dependent on the Dart VM service, so you *must* run
|
||||
Dart with the `--observe` (or `--enable-vm-service`) argument!!!
|
||||
## Usage
|
||||
|
||||
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`.
