Angel3 Static Files Handler #

version Null Safety Gitter License

This library provides a virtual directory to serve static files such as html, css and js for Angel3 framework. It can also handle Range requests, making it suitable for media streaming, i.e. music, video, etc.*

Installation #

In pubspec.yaml:

dependencies:
    angel3_static: ^4.0.0

Usage #

To serve files from a directory, you need to create a VirtualDirectory. Keep in mind that angel3_static uses package:file instead of dart:io.

import 'package:angel3_framework/angel3_framework.dart';
import 'package:angel3_framework/http.dart';
import 'package:angel3_static/angel3_static.dart';
import 'package:file/local.dart';

void main() async {
  var app = Angel();
  var fs = const LocalFileSystem();

  // Normal static server
  var vDir = VirtualDirectory(app, fs, source: Directory('./public'));

  // Send Cache-Control, ETag, etc. as well
  var vDir = CachingVirtualDirectory(app, fs, source: Directory('./public'));

  // Mount the VirtualDirectory's request handler
  app.fallback(vDir.handleRequest);

  // Start your server!!!
  await 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.

// Create VirtualDirectory as well
var vDir = 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 Angel3 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 angel3_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.
