|
|
|
|
Static server middleware for Angel.
|
|
|
|
# Installation
|
|
In `pubspec.yaml`:
|
|
|
|
```yaml
|
|
dependencies:
|
|
angel_static: ^1.1.0
|
|
```
|
|
|
|
# Usage
|
|
To serve files from a directory, your app needs to have a
|
|
`VirtualDirectory` mounted on it.
|
|
|
|
```dart
|
|
import 'dart:io';
|
|
import 'package:angel_framework/angel_framework.dart';
|
|
import 'package:angel_static/angel_static.dart';
|
|
|
|
main() async {
|
|
final app = new Angel();
|
|
|
|
// Normal static server
|
|
await app.configure(new VirtualDirectory(source: new Directory('./public')));
|
|
|
|
// Send Cache-Control, ETag, etc. as well
|
|
await app.configure(new CachingVirtualDirectory(source: new Directory('./public')));
|
|
|
|
await app.startServer();
|
|
}
|
|
```
|
|
|
|
# Push State Example
|
|
```dart
|
|
var vDir = new VirtualDirectory(...);
|
|
var indexFile = new File.fromUri(vDir.source.uri.resolve('index.html'));
|
|
|
|
app.after.add((req, ResponseContext res) {
|
|
// Fallback to index.html on 404
|
|
return res.sendFile(indexFile);
|
|
});
|
|
```
|
|
|
|
# Options
|
|
The `VirtualDirectory` API accepts a few named parameters:
|
|
- **source**: A `Directory` containing the files to be served. If left null, then Angel will serve either from `web` (in development) or
|
|
`build/web` (in production), depending on your `ANGEL_ENV`.
|
|
- **indexFileNames**: A `List<String>` of filenames that should be served as index pages. Default is `['index.html']`.
|
|
- **publicPath**: To serve index files, you need to specify the virtual path under which
|
|
angel_static is serving your files. If you are not serving static files at the site root,
|
|
please include this.
|
|
- **debug**: Print verbose debug output.
|
|
- **callback**: Runs before sending a file to a client. Use this to set headers, etc. If it returns anything other than `null` or `true`,
|
|
then the callback's result will be sent to the user, instead of the file contents.
|
|
- **streamToIO**: If set to `true`, files will be streamed to `res.io`, instead of added to `res.buffer`.. Default is `false`.
