shelf_virtual_directory 1.0.0+1

This package provides a virtual directory to serve static files from a shelf server.

Virtual Directory for Shelf

This package provides Handler, Router and Cascade to serve static files from the dart shelf server and can work with websockets.

Provider	UseCase
Handler	Can be used to serve as a handler for Pipeline or for Cascade
Router	Can be used to mount as a subroute
Cascade	Can be used directly serve from shelf server

Setup

1. Add to pubspec.yaml file

   dependencies:
       shelf_virtual_directory: latest_version
   

2. Get dependencies

   pub get
   

3. Import

   import 'package:shelf_virtual_directory/shelf_virtual_directory.dart';
   

4. Create a instance of ShelfVirtualDirectory with a directory ../web

   final virtualDir = ShelfVirtualDirectory(
        '../web'
        defaultFile:'index.html',
        default404File:'404.html',
        showLogs:true,
    );
   

   Note: index.html and 404.html files must be directly under root folder. In above case under web/ folder.

Handling different cases

• Using as a Handler

  final virDirHandler = ShelfVirtualDirectory('../web').handler;
  
  final staticFileHandler = const Pipeline()
      .addMiddleware(logRequests())
      .addHandler(virDirHandler);//used as a handler
  
  io.serve(Cascade().add(staticFileHandler).handler,address,port)
  .then((server){
      print('Server is sunning at ${server.address}:${server.port}'),
  });
  

• Using as a Router

  //As a subroute
  final router = Router()
  ..get('/otherroute',otherRoutehandler)
  ..mount('/',ShelfVirtualDirectory('../web').router); // localhost:8080/
  //or
  
  final router = Router()
  ..get('/otherroute',otherRouteHandler)
  ..mount('/home/',ShelfVirtualDirectory('../web').router);//localhost:8080/home/
  //or
  
  final router = Router()
  ..get('/otherroute',otherRouteHandler)
  ..get('/',ShelfVirtualDirectory('../web').handler)//at end
  

  Note: If your are planning to use it under home directory('/'), always mount or handle the ShelfVirtualDirectory at the end.

  Example

  final mainRoute = Router()
  ..get('/rest',(_)=>Respond.ok('Other routes'))
  ..mount('/',ShelfVirtualDirectory('../web').router);
  

• Using as a Cascade

  import 'package:shelf/shelf_io.dart' as io show serve;
  
  // You can add other handlers to this cascade
  final virDirCascade = ShelfVirtualDirectory('web').cascade;
  io.serve(virDirCascade.add(someOtherHandler),'localhost',8080)
  .then((server){
    print('Server is sunning at ${server.address}:${server.port}'),
  })
  

How it works?

It adds all the files under the given root directory as a route to a Router instance.

Example

web/
    - index.html
    - 404.html
    - js/
        - index.js
    - style/
        - index.css

All this will turn in to.

GET     /index.html
GET     /404.html
GET     /js/index.js
GET     /style/index.css

If user try to access other routes it will serve 404.html.
