JVM - api.route.all()

import io.nitric.Nitric;

public class Application {
  public static void main(String[] args) {
    var api = Nitric.INSTANCE.api("public");

    api.route("/customers").all((ctx) -> {
      // handle request
      return ctx;
    });

    Nitric.INSTANCE.run();
  }
}

Parameters

Name
middleware
Required
Required
Type
HttpMiddleware or List<HttpMiddleware>
Description
One or more middleware functions to use as the handler for HTTP requests. Handlers can be sync or async

Examples

Register a handler for requests

import io.nitric.Nitric;

public class Application {
  public static void main(String[] args) {
    var api = Nitric.INSTANCE.api("public");

    api.route("/customers").all((ctx) -> {
      // handle request
      return ctx;
    });

    Nitric.INSTANCE.run();
  }
}

Chain functions as a single method handler

When multiple functions 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.

import io.nitric.Nitric;
import io.nitric.faas.v0.HttpContext;
import io.nitric.faas.v0.Handler;

import java.util.List;

public class Application {
  static HttpContext validateRequest(HttpContext ctx, Handler<HttpContext> next) {
    // validateRequest
    return next.invoke(ctx);
  }

  static HttpContext handleRequest(HttpContext ctx, Handler<HttpContext> next) {
    // handle request
    return next.invoke(ctx);
  }

  public static void main(String[] args) {
    var api = Nitric.INSTANCE.api("public");

    api.route("/customer").all(List.of(Application::validateRequest, Application::handleRequest));

    Nitric.INSTANCE.run();
  }
}

Access the request body

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

import io.nitric.Nitric;

public class Application {
  public static void main(String[] args) {
    var api = Nitric.INSTANCE.api("public");

    api.route("/customer").all((ctx) -> {
      var customerData = ctx.getReq().getData();
      // parse, validate, and store the request payload...
    });

    Nitric.INSTANCE.run();
  }
}
