Dubbo-composer NPM

dubbo-composer

中文

It may be one of the best node calling dubbo solutions at present.

Precautions

Only supports zookeeper as a registration center
Only supports dubbo protocol
Do not use multiple versions of dubbo, it will be supported in the future

Advantage

Implement socket scheduling based on ip:port. Use long links to the maximum
Extremely simplified service configuration
Dynamically change provider information. Try to ensure the normal operation of the scheduler.
Random and polling load balancing algorithm

Usage

Interface definition document

const UserService = {
  name: "com.startlink.user.api.UserService",
  group: "",
  version: "0.0.1",
  mehods:{
    "register":{
      paramsType:[
          {
          $class: "com.startlink.user.dto.RegisterUserRequestDto",
          $: {
              userName: { $class: "java.lang.String" },
              password: { $class: "java.lang.String" },
            },
          },
        ],
      },
  }
};
module.exports = { UserService };

paramsType is compatible with version 0.0.2. If you do not configure this option, you can write all Java-style objects in subsequent calls.
paramsType 0.1.0 is not compatible with the interface definition method of version 0.0.2. Methods are proposed separately. It is recommended to use API generation tools to handle definitions elegantly.

Fortunately, the above interface definition is automatically generated

The definition based on java api can be automatically generated. The above interface definition is convenient for you to introduce into the project and start using it. This interface definition was not used until version 0.1.0

dubbo-composer-api-gen

const { UserService } = require("./service/userService");
const DubboComposer = require("dubbo-composer");
var config = {
  app: {
    name: "test-app",
  },
  zk: {
    addr:
      "zookeeper.1.inter:2181,zookeeper.2.inter:2182,zookeeper.3.inter:2183",
    root: "dubbo",
  },
  dubbo: {
    version: "2.7.6",
    timeout: 5,
  },
};

const dubbo = new DubboComposer(config);

var req = {
  userName:"周子豪",
  password:"Best of Dubbo-Node"
};

dubbo
  .proxy(UserService).register(req)
  .then((result) => {
    //... deal with result
  })
  .catch((err) => {
    // Oh!
  });

Known deficiency

~~The input parameter format is not simplified~~
~~There is no solution to support API generation interface for the time being~~
Interface has no good code hints
