Service<Id, Data> class

A front-facing interface that can present data to and operate on data on behalf of the user.

Heavily inspired by FeathersJS. <3

Inheritance

Constructors

Service.new({FutureOr<Data> readData(RequestContext, ResponseContext)?})
An optional readData function can be passed to handle non-map/non-json bodies.

Methods

addRoute(String method, String path, RequestHandler handler, {Iterable<RequestHandler> middleware = const {}}) → Route<RequestHandler>
Adds a route that responds to the given path for requests with the given method (case-insensitive). Provide '*' as the method to respond to all methods.
inherited
addRoutes([Service? service]) → void
Generates RESTful routes pointing to this class's methods.
all(String path, RequestHandler handler, {Iterable<RequestHandler> middleware = const []}) → Route<RequestHandler>
Adds a route that responds to any request matching the given path.
inherited
chain(Iterable<RequestHandler> middleware) → ChainedRouter<RequestHandler>
Prepends the given middleware to any routes created by the resulting router.
inherited
clone() → Router<RequestHandler>
Returns a Router with a duplicated version of this tree.
inherited
close() → void
Closes this service, including any database connections or stream controllers.
override
create(Data data, [Map<String, dynamic>? params]) → Future<Data>
Creates a resource.
delete(String path, RequestHandler handler, {Iterable<RequestHandler> middleware = const []}) → Route<RequestHandler>
Adds a route that responds to a DELETE request.
inherited
dumpTree({dynamic callback(String tree)?, String header = 'Dumping route tree:', String tab = ' '}) → void
Creates a visual representation of the route hierarchy and passes it to a callback. If none is provided, print is called.
inherited
enableCache() → void
Enables the use of a cache to eliminate the overhead of consecutive resolutions of the same path.
inherited
findHookedService<T extends Service>(Pattern path) → HookedService<dynamic, dynamic, T>?
Shorthand for finding a HookedService in a statically-typed manner.
inherited
findOne([Map<String, dynamic>? params, String errorMessage = 'No record was found matching the given query.']) → Future<Data>
Retrieves the first object from the result of calling index with the given params.
findService<T extends Service>(Pattern path) → T?
Retrieves the service assigned to the given path.
inherited
findServiceOf<Id, Data>(Pattern path) → Service<Id, Data>?
Shorthand for finding a Service in a statically-typed manner.
inherited
get(String path, RequestHandler handler, {Iterable<RequestHandler> middleware = const []}) → Route<RequestHandler>
Adds a route that responds to a GET request.
inherited
group(String path, void callback(Router<RequestHandler> router), {Iterable<RequestHandler> middleware = const [], String name = ''}) → SymlinkRoute<RequestHandler>
Creates a route, and allows you to add child routes to it via a Router instance.
inherited
groupAsync(String path, FutureOr<void> callback(Router<RequestHandler> router), {Iterable<RequestHandler> middleware = const [], String name = ''}) → Future<SymlinkRoute<RequestHandler>>
Asynchronous equivalent of group.
inherited
Adds a route that responds to a HEAD request.
inherited
index([Map<String, dynamic>? params]) → Future<List<Data>>
Retrieves all resources.
map<U>(U encoder(Data), Data decoder(U), {FutureOr<U> readData(RequestContext, ResponseContext)?}) → Service<Id, U>
Creates an AnonymousService that wraps over this one, and maps input and output using two converter functions.
modify(Id id, Data data, [Map<String, dynamic>? params]) → Future<Data>
Modifies a resource.
mount(String path, Router<RequestHandler> router) → SymlinkRoute<RequestHandler>
Incorporates another Router's routes into this one's.
inherited
Generates a URI string based on the given input. Handy when you have named routes.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
onHooked(HookedService<dynamic, dynamic, Service> hookedService) → void
Invoked when this service is wrapped within a HookedService.
options(String path, RequestHandler handler, {Iterable<RequestHandler> middleware = const {}}) → Route<RequestHandler>
Adds a route that responds to a OPTIONS request.
inherited
patch(String path, RequestHandler handler, {Iterable<RequestHandler> middleware = const []}) → Route<RequestHandler>
Adds a route that responds to a PATCH request.
inherited
post(String path, RequestHandler handler, {Iterable<RequestHandler> middleware = const []}) → Route<RequestHandler>
Adds a route that responds to a POST request.
inherited
put(String path, RequestHandler handler, {Iterable<RequestHandler> middleware = const []}) → Route
Adds a route that responds to a PUT request.
inherited
read(Id id, [Map<String, dynamic>? params]) → Future<Data>
Retrieves the desired resource.
readMany(List<Id> ids, [Map<String, dynamic>? params]) → Future<List<Data>>
Reads multiple resources at once.
remove(Id id, [Map<String, dynamic>? params]) → Future<Data>
Removes the given resource.
resolve(String absolute, String relative, List<RoutingResult<RequestHandler?>> out, {String method = 'GET', bool strip = true}) → bool
Finds the first Route that matches the given path, with the given method.
inherited
resolveAbsolute(String path, {String method = 'GET', bool strip = true}) → Iterable<RoutingResult<RequestHandler>>
Returns the result of resolve with path passed as both absolute and relative.
inherited
resolveAll(String absolute, String relative, {String method = 'GET', bool strip = true}) → Iterable<RoutingResult<RequestHandler>>
Finds every possible Route that matches the given path, with the given method.
inherited
toString() → String
A string representation of this object.
inherited
update(Id id, Data data, [Map<String, dynamic>? params]) → Future<Data>
Overwrites a resource.
use<Id, Data, T extends Service<Id, Data>>(String path, T service) → HookedService<Id, Data, T>
Mounts a service at the given path.
inherited

Operators

operator ==(Object other) → bool
The equality operator.
inherited

Static Methods

parseId<T>(dynamic id) → T
Transforms an id (whether it is a String, num, etc.) into one acceptable by a service.

Constants

specialQueryKeys → const List<String>
A List of keys that services should ignore, should they see them in the query.
