How it works?

Server side

Your server api in a plain old class defining your interface.

Example:

export default class Api {
  hello() {
    return `Hello World from Worker ${Date.now()}`;
  }
}

This code expose an API called hello which returns a string "Hello World from Worker" concatened with server timestamp.

You can use injected platform services with to following.

Dependency injection use injection-js

const { Injectable } = require('@zetapush/core');
const { Stack } = require('@zetapush/platform-legacy');

export default class Api {
  constructor(private stack: Stack) {}
  push(item) {
    return this.stack.push({ stack: 'list', data: item });
  }
  list() {
    return this.stack.list({ stack: 'list' });
  }
}

To consume an API in your front-end application you have to create a mapped method.

Client side

Register your API mapping class

const api = client.createProxyTaskService();

Invoke your remote API method

const message = await api.hello();
