Example (Single link, with options):

var cronLink = require("node-cron-link");
cronLink({ // link as object
  url: "https://ipinfo.io/ip", // link to call
  time: 2, // call it every 2 minutes.
  callback: function(error, response, body) { // callback after link is called
    console.log(error, body);
  }
}, {kickStart: true});

• In the above example, please check that link is passed as an object. You can provide more request options to the link object like json: true. Please check more here: https://www.npmjs.com/package/request

Example (Multiple links):

var cronLink = require("node-cron-link");
cronLink(
  ["https://ipinfo.io/ip",
  "https://httpbin.org/get"],
  {time: 2, kickStart: true} // every 2 minutes in
);

Example (Multiple links, with options):

var cronLink = require("node-cron-link");
cronLink(
  [{ // link as object
    url: "https://ipinfo.io/ip", // link to call
    time: 2, // call it every 2 minutes.
    callback: function(error, response, body) { // callback after link is called
      console.log(error, body);
    }
  },
  { // link as object
    url: "https://httpbin.org/get", // json
    time: 5, // call it every 5 minutes.
    json: true,
    callback: function(error, response, body) { // callback after link is called
      console.log(error, body);
    }
  }],
  {kickStart: true}
);

Example - Global config for all links:

var cronLink = require("node-cron-link");
cronLink(
  [{ // link as object
    url: "https://ipinfo.io/ip", // link to call
    callback: function(error, response, body) { // callback after link is called
      console.log(error, body);
    }
  },
  { // link as object
    url: "https://httpbin.org/get", // json
    json: true,
    callback: function(error, response, body) { // callback after link is called
      console.log(error, body);
    }
  }],
  { //default config for all links
    name: "node-cron-link", // any friendly name for console log.
    time: 3, // run every 3 minutes
    consoleLog: true, // whether to log useful info in console.
    kickStart: true // if true will call links right away without waiting for set time.
  }
);

Example - Same callback:

var cronLink = require("node-cron-link");
var callback = function(error, response, body) { // callback after link is called
  console.log(error, body);
}
cronLink(
  [{ // link as object
    url: "https://ipinfo.io/ip", // link to call
    time: 2, // call it every 2 minutes.
    callback: callback
  },
  { // link as object
    url: "https://httpbin.org/get", // json
    time: 5, // call it every 5 minutes.
    json: true,
    callback: callback
  }],
  {kickStart: true}
);

Example - POST: Just add the form OR formData with link object.

var cronLink = require("node-cron-link");
cronLink(
  [{ // link as object
    url: "https://httpbin.org/post", // link to call
    time: 2, // call it every 2 minutes.
    form: {this: "that", that: "this"},
    json: true,
    callback: function(error, response, body) { // callback after link is called
      console.log(error, body);
    }
  }],
  {kickStart: true}
);

Check console log for the time it takes to call every link, and the time when the link was called. Default consoleLog is true.
