Track your JavaScript cron jobs

Track your JavaScript cron jobs

When setting up cron jobs in JavaScript, it is usually crucial to keep track of their execution and whether they have been executed successfully or not. Sometimes, a minor failure in a cronjob can cause your JavaScript application to stop working correctly. LogSnag makes it easy to track your cron jobs and their execution status all in real-time, and it works seamlessly with your JavaScript code.

Connect LogSnag to JavaScript

Setting up your account

Setting up LogSnag with JavaScript is very simple!

  1. Create a free LogSnag account.
  2. Create a new project on your dashboard.
  3. Copy your API token from the settings page.

JavaScript code snippets

Once your LogSnag account is set up, you can use the following code snippets to track your cron jobs. Just replace the YOUR_API_TOKEN with your LogSnag API token and update your project name.

Using JavaScript with Fetch 
var myHeaders = new Headers();
myHeaders.append("Content-Type", "application/json");
myHeaders.append("Authorization", "Bearer YOUR_API_TOKEN");

var raw = JSON.stringify({
  "project": "my-saas",
  "channel": "cronjobs",
  "event": "Cronjob Started",
  "description": "job: email-notifications",
  "icon": "⏰",
  "notify": true
});

var requestOptions = {
  method: 'POST',
  headers: myHeaders,
  body: raw,
  redirect: 'follow'
};

fetch("https://api.logsnag.com/v1/log", requestOptions)
  .then(response => response.text())
  .then(result => console.log(result))
  .catch(error => console.log('error', error));
Using JavaScript with jQuery 
var settings = {
  "url": "https://api.logsnag.com/v1/log",
  "method": "POST",
  "timeout": 0,
  "headers": {
    "Content-Type": "application/json",
    "Authorization": "Bearer YOUR_API_TOKEN"
  },
  "data": JSON.stringify({
    "project": "my-saas",
    "channel": "cronjobs",
    "event": "Cronjob Started",
    "description": "job: email-notifications",
    "icon": "⏰",
    "notify": true
  }),
};

$.ajax(settings).done(function (response) {
  console.log(response);
});
Using JavaScript with XHR 
// WARNING: For POST requests, body is set to null by browsers.
var data = JSON.stringify({
  "project": "my-saas",
  "channel": "cronjobs",
  "event": "Cronjob Started",
  "description": "job: email-notifications",
  "icon": "⏰",
  "notify": true
});

var xhr = new XMLHttpRequest();
xhr.withCredentials = true;

xhr.addEventListener("readystatechange", function() {
  if(this.readyState === 4) {
    console.log(this.responseText);
  }
});

xhr.open("POST", "https://api.logsnag.com/v1/log");
xhr.setRequestHeader("Content-Type", "application/json");
xhr.setRequestHeader("Authorization", "Bearer YOUR_API_TOKEN");

xhr.send(data);
