Simple example how to call screenshot machine's API using Node.js.

screenshotmachine-nodejs

Captures website screenshot and converts website to PDF using Screenshot machine - online website screenshot generator and website to PDF converter

Installation

Install Node.js package:

npm install screenshotmachine --save

First, you need to create a free/premium account at www.screenshotmachine.com website. After registration, you will see your customer key in your user profile. Also secret phrase is maintained here. Please, use secret phrase always, when your API calls are called from publicly available websites.

Set-up your customer key and secret phrase (if needed) in the script:

var customerKey = 'PUT_YOUR_CUSTOMER_KEY_HERE';
    secretPhrase = ''; //leave secret phrase empty, if not needed

Website screenshot API

Set additional options to fulfill your needs:

    options = {
      //mandatory parameter
      url : 'https://www.google.com',
      // all next parameters are optional, see our website screenshot API doc for more details
      dimension : '1366xfull', // or "1366xfull" for full length screenshot
      device : 'desktop',
      format: 'png',
      cacheLimit: '0',
      delay: '200',
      zoom: '100'
    }

More info about options can be found in our Website screenshot API.

Sample code

var screenshotmachine = require('screenshotmachine');

var customerKey = 'PUT_YOUR_CUSTOMER_KEY_HERE';
    secretPhrase = ''; //leave secret phrase empty, if not needed
    options = {
      //mandatory parameter
      url : 'https://www.google.com',
      // all next parameters are optional, see our website screenshot API guide for more details
      dimension : '1366xfull', // or "1366xfull" for full length screenshot
      device : 'desktop',
      format: 'png',
      cacheLimit: '0',
      delay: '200',
      zoom: '100'
    }

var apiUrl = screenshotmachine.generateScreenshotApiUrl(customerKey, secretPhrase, options);

//put link to your html code
console.log('<img src="' + apiUrl + '">');  

Generated apiUrl link can be placed in <img> tag or used in your business logic later.

If you need to store captured screenshot as an image, just call:

var screenshotmachine = require('screenshotmachine');

var customerKey = 'PUT_YOUR_CUSTOMER_KEY_HERE';
    secretPhrase = ''; //leave secret phrase empty, if not needed
    options = {
      //mandatory parameter
      url : 'https://www.google.com',
      // all next parameters are optional, see our website screenshot API guide for more details
      dimension : '1366xfull', // or "1366xfull" for full length screenshot
      device : 'desktop',
      format: 'png',
      cacheLimit: '0',
      delay: '200',
      zoom: '100'
    }

var apiUrl = screenshotmachine.generateScreenshotApiUrl(customerKey, secretPhrase, options);

//save screenshot as an image
var fs = require('fs');
var output = 'output.png';
screenshotmachine.readScreenshot(apiUrl).pipe(fs.createWriteStream(output).on('close', function() {
  console.log('Screenshot saved as ' + output);
}));

Captured screenshot will be saved as output.png file in current directory.

Website to PDF API

Set the PDF options:

    options = {
      //mandatory parameter
      url : 'https://www.google.com',
      // all next parameters are optional, see our website to PDF API guide for more details
      paper : 'letter',
      orientation : 'portrait',
      media: 'print',
      bg: 'nobg',
      delay: '2000',
      scale: '50'
    }
