Express.js bindings for Dart

Classes

ExpressAppMultiHandler on ExpressApp: Extension for routes with multiple handlers (middleware + handler)
ResponseExtensions on Response: Extension for convenient methods

asyncHandler(AsyncRequestHandler handler) → JSFunction: Wraps an async handler for Express.js compatibility.
bool_() → BoolValidator: Create a bool validator
chain(List<JSFunction> middlewares) → JSFunction: Chains multiple middleware functions into a single handler.
errorHandler() → JSFunction: Express error handler middleware.
express() → ExpressApp: Create an Express application
getContext<T>(Request req, String key) → T?: Gets a value from the request context.
getValidatedBody<T>(Request req) → T: Get validated body from request (use after validateBody middleware)
handler(RequestHandler fn) → JSFunction: Convert a Dart handler to a JS function
int_() → IntValidator: Create an int validator
middleware(MiddlewareHandler handler) → JSFunction: Converts a Dart middleware to JS function.
optional<T>(Validator<T> inner) → OptionalValidator<T>: Make a validator optional (null is valid)
schema<T>(Map<String, Validator> fields, T constructor(Map<String, dynamic>)) → Schema<T>: Create a schema for validating objects
setContext<T>(Request req, String key, T value) → void: Sets a value in the request context.
string() → StringValidator: Create a string validator
validateBody<T>(Schema<T> schema) → JSFunction: Create middleware that validates request body

AsyncRequestHandler = Future<void> Function(Request req, Response res): Type definition for async request handlers
MiddlewareHandler = void Function(Request req, Response res, NextFunction next): Type for synchronous middleware
NextFunction = void Function(): Type for Express next function
RequestHandler = void Function(Request req, Response res): Handler function type
