|
|
|
|
Static server middleware for Angel.
|
|
|
|
# Installation
|
|
In `pubspec.yaml`:
|
|
|
|
```yaml
|
|
dependencies:
|
|
angel_static: ^2.0.0-alpha
|
|
```
|
|
|
|
# Usage
|
|
To serve files from a directory, you need to create a `VirtualDirectory`.
|
|
Keep in mind that `angel_static` uses `package:file` instead of `dart:io`.
|
|
|
|
```dart
|
|
import 'package:angel_framework/angel_framework.dart';
|
|
import 'package:angel_framework/http.dart';
|
|
import 'package:angel_static/angel_static.dart';
|
|
import 'package:file/local.dart';
|
|
|
|
main() async {
|
|
var app = new Angel();
|
|
var fs = const LocalFileSystem();
|
|
|
|
// Normal static server
|
|
var vDir = new VirtualDirectory(app, fs, source: new Directory('./public'));
|
|
|
|
// Send Cache-Control, ETag, etc. as well
|
|
var vDir = new CachingVirtualDirectory(app, fs, source: new Directory('./public'));
|
|
|
|
// Mount the VirtualDirectory's request handler
|
|
app.fallback(vDir.handleRequest);
|
|
|
|
// Start your server!!!
|
|
await new AngelHttp(app).startServer();
|
|
}
|
|
```
|
|
|
|
# Push State
|
|
`VirtualDirectory` also exposes a `pushState` method that returns a
|
|
request handler that serves the file at a given path as a fallback, unless
|
|
the user is requesting that file. This can be very useful for SPA's.
|
|
|
|
```dart
|
|
// Create VirtualDirectory as well
|
|
var vDir = new CachingVirtualDirectory(...);
|
|
|
|
// Mount it
|
|
app.fallback(vDir.handleRequest);
|
|
|
|
// Fallback to index.html on 404
|
|
app.fallback(vDir.pushState('index.html'));
|
|
```
|
|
|
|
# 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.
|
|
- **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. |
