Quick Start

First, install the dependencies

npm i

Then write

node . -s

Usage

 usage: node . [--help | -h] [--new-license | -nl <number in how many days to expire in days>]
               [--start | -s]

Configuration file

{
  "ip": "The IP address where you want to deploy the server",
  "port": "port on which to deploy the server must be a number",
  "licenseListPath": "Path to token/license file, path must be relative, e.g. \"./licenseList.json\", only .json files are supported",
  "updateInterval": "The time to check if the licenses/tokens have expired should be a number in milliseconds, for example 1800000 (30 minutes)"
}

Examples of Rest Requests

This example will use the axios module

get:

ping

    axios.get('http://ip_on_where_the_server_is:port/ping')
        .then(res => console.log(res.data))
//Expected output: OK

post:

checkKey

    axios.post('http://ip_on_where_the_server_is:port/checkKey', {token: "токен сегенерированным сервером"})
        .then(res => console.log(res.data))
//Expected output: 
// { 
// "checkStatus": true 
// }

Generating a new token

Example with token expiration in 10 days

node . -nl 10

The new token will be added to the license list file and will be displayed in the console

Expected output:

new token:  3afeuc5kkY99MAxd

Use with the pm2

Install pm2:

npm i pm2@latest -g
