shelf_plus library

Classes

Cascade
A helper that calls several handlers in sequence and returns the first acceptable response.
Pipeline
A helper that makes it easy to compose a set of Middleware and a Handler.
Request
An HTTP request to be processed by a Shelf application.
RequestBodyAccessor
Reference class for different request body accessors. Provides basic accessors like asString or asJson.
Response
The response returned by a Handler.
Route
Annotation for handler methods that requests should be routed when using package shelf_router_generator.
Router
A shelf Router routes requests to handlers based on HTTP verb and route pattern.
RouterPlus
Extended request router based on shelf Router
Server
An adapter with a concrete URL.
ServerHandler
A connected pair of a Server and a Handler.
ShelfRunContext
WebSocketSession
Abstraction of a websocket lifecycle

Functions

addResponseHandler(List<ResponseHandler> handler) → Middleware
cascade(List<Handler> handler) → Handler
Merges multiple Handler into a cascade of handler. Uses the shelf Cascade ruleset.
createFileHandler(String path, {String? url, String? contentType}) → Handler
Creates a shelf Handler that serves the file at path.
createMiddleware({FutureOr<Response?> requestHandler(Request)?, FutureOr<Response> responseHandler(Response)?, FutureOr<Response> errorHandler(Object error, StackTrace)?}) → Middleware
Creates a Middleware using the provided functions.
createStaticHandler(String fileSystemPath, {bool serveFilesOutsidePath = false, String? defaultDocument, bool listDirectories = false, bool useHeaderBytesForContentType = false, MimeTypeResolver? contentTypeResolver}) → Handler
Creates a Shelf Handler that serves files from the provided fileSystemPath.
download({String? filename}) → Middleware
Changes the response headers in a way, browsers will handle the http response as a download.
logRequests({void logger(String message, bool isError)?}) → Middleware
Middleware which prints the time of the request, the elapsed time for the inner handlers, the response's status code and the request URI.
params(Request request, String name) → String
Get a URL parameter captured by the Router.
resolveResponse(Request request, dynamic result) → Future<Response>
Resolves a shelf Response from generic result based on registered ResponseHandler.
setContentType(String mimeType) → Middleware
Sets the content type header of the response to given mimeType.
shelfRun(FutureOr<Handler> init(), {int defaultBindPort = 8080, Object defaultBindAddress = 'localhost', bool defaultEnableHotReload = true, bool defaultShared = false, SecurityContext? securityContext, OnStarted? onStarted, OnStartFailed? onStartFailed, OnWillClose? onWillClose, OnClosed? onClosed}) → Future<ShelfRunContext>
Mechanism to quickly run a shelf app.
typeByExtension(String fileExtension, {String unknownMimeType = 'application/unknown'}) → Middleware
Sets the content type header of the response to a mime-type that matches the give fileExtension.

Typedefs

Handler = FutureOr<Response> Function(Request request)
A function which handles a Request.
Middleware = Handler Function(Handler innerHandler)
A function which creates a new Handler by wrapping a Handler.
OnClosed = FutureOr<void> Function()
OnStarted = void Function(Object address, int port)
OnStartFailed = void Function(Object e)
The type e represents the error or exception that occurred.
OnWillClose = FutureOr<void> Function()
ResponseHandler = FutureOr<Object?> Function(Request request, dynamic data)
Model for converting an object into another one.

Exceptions / Errors

HijackException
An exception used to indicate that a request has been hijacked.
