Monitor when a user exceeds the usage limit for your NodeJs service

These days, a lot of services are moving to a pay-as-you-go model. This model is either based on a monthly usage limit or metered usage. This is especially common for cloud, software, and other online services. So, chances are that if you're building a service with NodeJs, you'll have to roll your usage model and limits.

No matter your implementation, you will be required to set up an internal system to track usage and notify yourself and your team when a user has reached their limit. This is a common enough problem as it helps you understand how your users use your service, and you can improve your product based on that.

LogSnag is a service that helps you monitor your important events in real-time. It's an excellent tool for this problem and works seamlessly with NodeJs. In addition, LogSnag makes it trivial to send events to your dashboard and receive push notifications when something important happens.

For example, let's say you're building a service with NodeJs that allows users to upload files. However, you want to limit the number of files a user can upload to 10. You can use LogSnag to send an event to your dashboard when a user uploads a file. You can then set up a rule to notify you when a user has uploaded ten files. This way, you will know when a user has reached their limit, allowing you to take further action if needed.

NodeJs code snippets

Copy the following code snippet to your NodeJs project. Please note that you will need to replace the API token with your own.

Using NodeJs with Axios

const axios = require('axios');
let data = JSON.stringify({
  "project": "my-saas",
  "channel": "limits",
  "event": "Usage Limit Exceeded",
  "description": "The user has exceeded the usage limit for the service.",
  "icon": "🚨",
  "notify": true
});

let config = {
  method: 'post',
  maxBodyLength: Infinity,
  url: 'https://api.logsnag.com/v1/log',
  headers: { 
    'Content-Type': 'application/json', 
    'Authorization': 'Bearer YOUR_API_TOKEN'
  },
  data : data
};

axios.request(config)
.then((response) => {
  console.log(JSON.stringify(response.data));
})
.catch((error) => {
  console.log(error);
});

Using NodeJs with Native

var https = require('follow-redirects').https;
var fs = require('fs');

var options = {
  'method': 'POST',
  'hostname': 'api.logsnag.com',
  'path': '/v1/log',
  'headers': {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_TOKEN'
  },
  'maxRedirects': 20
};

var req = https.request(options, function (res) {
  var chunks = [];

  res.on("data", function (chunk) {
    chunks.push(chunk);
  });

  res.on("end", function (chunk) {
    var body = Buffer.concat(chunks);
    console.log(body.toString());
  });

  res.on("error", function (error) {
    console.error(error);
  });
});

var postData = JSON.stringify({
  "project": "my-saas",
  "channel": "limits",
  "event": "Usage Limit Exceeded",
  "description": "The user has exceeded the usage limit for the service.",
  "icon": "🚨",
  "notify": true
});

req.write(postData);

req.end();

Using NodeJs with Request

var request = require('request');
var options = {
  'method': 'POST',
  'url': 'https://api.logsnag.com/v1/log',
  'headers': {
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_TOKEN'
  },
  body: JSON.stringify({
    "project": "my-saas",
    "channel": "limits",
    "event": "Usage Limit Exceeded",
    "description": "The user has exceeded the usage limit for the service.",
    "icon": "🚨",
    "notify": true
  })

};
request(options, function (error, response) {
  if (error) throw new Error(error);
  console.log(response.body);
});

Using NodeJs with Unirest

var unirest = require('unirest');
var req = unirest('POST', 'https://api.logsnag.com/v1/log')
  .headers({
    'Content-Type': 'application/json',
    'Authorization': 'Bearer YOUR_API_TOKEN'
  })
  .send(JSON.stringify({
    "project": "my-saas",
    "channel": "limits",
    "event": "Usage Limit Exceeded",
    "description": "The user has exceeded the usage limit for the service.",
    "icon": "🚨",
    "notify": true
  }))
  .end(function (res) { 
    if (res.error) throw new Error(res.error); 
    console.log(res.raw_body);
  });
