ChatWars API NodeJS wrapper and REST API HTTP server

NodeJS interface

This project provides promise-based ChatWars interface as NPM library.

A sample of the NodeJs library usage is demonstrated in alevinru/CWClientHelperAppBot Telegram bot project.

If you are not interested in utilising REST API, then you could go straight to the sample bot project, and do not setup the REST server described below. However, in order to serve the bot you'll have to provide some env variables declared below in the setup section.

Shell

npm i --save cw-rest-api

NodeJS

node-amqp-connection-manager is used to provide AMQP node reconnection.

import CWExchange from 'cw-rest-api';

// Assuming you've already done user authorization and got token
const USER_ID = parseInt(process.env.USER_ID, 0);
const USER_TOKEN = process.env.USER_TOKEN;

const cw = new CWExchange(); // optional params { appName, timeOut }
const manager = cw.connect(); // optional params { apiUrl, accessToken, amqpProtocol }

// manager is an instance of amqp-connection-manager

manager.on('connect', async () => {

  try {

    const profile = await cw.requestProfile(USER_ID, USER_TOKEN)
    console.log(profile);

    const stock = await cw.requestStock(USER_ID, USER_TOKEN);
    console.log(stock);

    // as a promise without await

    cw.wantToBuy(USER_ID, { itemCode: '07', quantity: 12, price: 1 }, USER_TOKEN)
      .then(deal => console.log(deal))
      .catch(errorText => console.error(errorText));

  } catch (e) {
    console.error(e);
  }

});

ChatWars REST API HTTP server

Install

git clone [email protected]:alevinru/CWClient.git

cd CWClient

Setup

Since you've got managed to request and obtain valid CW API credentials you must have username and password. It is required to set them into the environment variables named respectively as CW_APP_NAME and CW_APP_PASSWORD.

export CW_APP_NAME=username
export CW_APP_PASSWORD=password

By default, http server starts on port 8888 and connects to CW3 api instance. This is configurable with environment variables for which default values are provided in the bundled nodemon.json file.

Run

npm run start

Upon success you need to get a valid CW usesId and ask that user for an authorization doing:

http POST localhost:8888/api/auth/101010101

Then CW Telegram Bot sends an authorization request message to the user Telegram account

Code 11223344 to authorize aliovin_CWClientAppBot. This app will have the access to:
 - read your profile information
 - issue a wtb/wts/rm commands on your behalf
 - read your stock info

Now you need to use this code to get user token:

http POST /api/token/101010101/11223344

If everything's fine you would get a response like that:

{
    "id": "1a2346c48ee342367d0e6af3c155b744",
    "token": "0c32d64ac6f348cfae7e441f317fd898",
    "userId": 101010101
}

You should remember the user token and use it for accessing user data methods:

export USER_TOKEN=0c32d64ac6f348cfae7e441f317fd898

Now you should be able to use all the rest of the API methods passing the received token as a http header.

http POST /api/profile/101010101 authorization:$USER_TOKEN
