Dart - api.all()

This method is a convenient short version of api().route().all()

import 'package:nitric_sdk/nitric.dart';

// Create an API named 'public'
final api = Nitric.api("public");

api.all("/customers/:customersId", (ctx) async {
  // construct a response for all incoming HTTP requests
  final responseBody = {};
  ctx.res.json(responseBody);

  return ctx;
});

Parameters

Name
match
Required
Required
Type
String
Description
The path matcher to use for the route. Matchers accept path parameters in the form of a colon prefixed string. The string provided will be used as that path parameter's name when calling handlers.
Name
handler
Required
Required
Type
HttpHandler
Description
The middleware service to use as the handler for HTTP requests.
Name
security
Optional
Optional
Type
List<OidcOptions>
Description
Security rules to apply with scopes to the entire API.
Name
middlewares
Optional
Optional
Type
List<HttpHandler>
Description
The list of middleware that will run before the handler is called. To call the next middleware in the chain use ctx.next(), to finish early return ctx by itself. The ordering of middleware goes: API -> Route -> Method.

Examples

Register a handler for all requests

import 'package:nitric_sdk/nitric.dart';

// Create an API named 'public'
final api = Nitric.api("public");

api.all("/customers/:customersId", (ctx) async {
  // construct a response for all incoming HTTP requests
  final responseBody = {};
  ctx.res.json(responseBody);

  return ctx;
});

Chain services as a single method handler

When multiple services are provided they will be called as a chain. If one succeeds, it will move on to the next. This allows middleware to be composed into more complex handlers. You can call the next middleware in the chain using ctx.next(). If a middleware in the chain does not call .next and instead returns the base context, the call chain will end.

import 'package:nitric_sdk/nitric.dart';
import '../middlewares';

Future<HttpContext> validate(HttpContext ctx) async {
  if (!ctx.req.headers.containsKey("Content-Type")) {
    ctx.res.status = 400;
    ctx.res.body = "header Content-Type is required";

    // End the middleware chain by not calling `ctx.next()`.
    return ctx;
  }

  return ctx.next();
}

Future<HttpContext> handleCustomer(HttpContext ctx) async {
  // handle the request...
  return ctx.next();
}

// The validate middleware will run before the handleCustomer handler
Nitric.api("public").all("/customers", handleCustomer, middlewares: [validate]);

Access the request body

The request body is accessible from the ctx.req object.

import 'package:nitric_sdk/nitric.dart';

// Create an API named 'public'
final api = Nitric.api("public");

api.all("/customers/:customerId", (ctx) async {
  // Extract the path parameter
  final id = ctx.req.pathParams["customerId"]!;

  // Extract the request body
  final body = ctx.req.json();

  // Construct response for the /customers request...
  final responseBody = {};
  ctx.res.json(responseBody);

  return ctx;
});
