Node.js is an open-source, cross-platform, back-end JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser. To scan for malware in file using Javascript, we offer three sample code snippets using different method. Alternatives includes using the code snippets below using Axios, Native, Request, and Unirest.

For the Javascript tutorial, please check out this link.

Instructions

1. Get a free API to use by signing up at FileScanAPI.com and replace REPLACE_ME with your API key.
2. Update location value in payload with url location of your file.
3. Update callback value in payload to your webhook url. We recommend using webhook.site as a callback url during test.

For 2 and 3, you can find this documented at Offical Documentation

 

Using Axios to check file for malware in Node.js

const axios = require('axios');
let data = JSON.stringify({
  "location": "https://filescanapi.com/icon.png",
  "metadata": {
    "filename": "demo.png"
  },
  "callback": "https://webhook.site"
});

let config = {
  method: 'post',
  maxBodyLength: Infinity,
  url: 'https://api.filescanapi.com/v1/file/async',
  headers: {
    'x-api-key': 'REPLACE_ME',
    'Content-Type': 'application/json'
  },
  data : data
};

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

 

Using Native to check for virus in file in Node.js

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

var options = {
  'method': 'POST',
  'hostname': 'api.filescanapi.com',
  'path': '/v1/file/async',
  'headers': {
    'x-api-key': 'REPLACE_ME',
    'Content-Type': 'application/json'
  },
  '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({
  "location": "https://filescanapi.com/icon.png",
  "metadata": {
    "filename": "demo.png"
  },
  "callback": "https://webhook.site"
});

req.write(postData);

req.end();

 

Using Request to scan for malware in file in Node.js

var request = require('request');
var options = {
  'method': 'POST',
  'url': 'https://api.filescanapi.com/v1/file/async',
  'headers': {
    'x-api-key': 'REPLACE_ME',
    'Content-Type': 'application/json'
  },
  body: JSON.stringify({
    "location": "https://filescanapi.com/icon.png",
    "metadata": {
      "filename": "demo.png"
    },
    "callback": "https://webhook.site"
  })

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

 

Using Unirest to scan for malware in file in Node.js

var unirest = require('unirest');
var req = unirest('POST', 'https://api.filescanapi.com/v1/file/async')
  .headers({
    'x-api-key': 'REPLACE_ME',
    'Content-Type': 'application/json'
  })
  .send(JSON.stringify({
    "location": "https://filescanapi.com/icon.png",
    "metadata": {
      "filename": "demo.png"
    },
    "callback": "https://webhook.site"
  }))
  .end(function (res) {
    if (res.error) throw new Error(res.error);
    console.log(res.raw_body);
  });
