Delay reading body until npm request completes

My current challenge involves using npm request and cheerio to extract webpages and analyze their HTML structure. Everything works smoothly in scenarios where the HTML is available upon request. However, I am facing a problem when a website initially displays a loading screen before updating its content with new information / elements after a short delay.

Snippet of my code:

var url = 'website with loading screen prior to content.com';
var request = require('request');
request(url, function (error, response, body) {
  if (!error && response.statusCode == 200) {
    console.log(body) // Display the HTML for the Google homepage.
  }
})

Desired Solution - I am looking for a way for the request function to either wait for a specific element to appear on the page before reading the body, or alternatively, to wait for a predefined number of seconds before processing the body.

Exploring Alternatives - It's plausible that achieving this with npm request may not be viable. In such a case, I am open to suggestions on alternative approaches. One option I am contemplating is utilizing webdriver.io or phantomjs. Could you provide guidance on which path to take?

Answer №1

Regrettably, there is no option to set up request to pause after initiating the request before receiving a response. Your best bet would be to explore PhantomJS. This is a headless browser that can load and render the page, allowing you to access dynamically generated content through javascript.

For a quick example, take a look at this solution.
