# hot
|
|
[](https://pub.dartlang.org/packages/angel_rethink)
|
|
|
|
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](https://github.com/angel-dart/angel).
|
|
|
|
# Installation
|
|
In your `pubspec.yaml`:
|
|
|
|
```yaml
|
|
dependencies:
|
|
angel_framework: ^1.0.0
|
|
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
