Reuse Electron Session With Nightmare

I am using Nightmare.js to print pdf's. I send a request to the node server and build the page, using Nightmare to ensure the page has loaded, then print a pdf. But for each reque

Solution 1:

You need to create the nightmare instance once and not in a loop.

var page = nightmare()
    .goto('file:\\\\' + __dirname + '\\index.html');

This creates new nightmare instance each time you create a page. You can create instance once

constNightmare = require('nightmare');
const browser = Nightmare();

Then use it each time with browser.goto(url). You can chain your goto statment using answers given at: https://github.com/segmentio/nightmare/issues/708

Extract from one of the answers:

functionrun() {
  var nightmare = Nightmare();
  yield nightmare
    .goto('https://www.example.com/signin')
    .type('#login', 'username')
    .type('#password', 'password')
    .click('#btn')

  for (var i = 0; i < 4; i++) {
    yield nightmare
      .goto('https://www.example.com/page'+i)
      .wait(1000)
      .evaluate(function(){
        return $('#result > h3').text()
      })
  }

  yield nightmare.end()
}

You can also create multiple browsers, for pooling as well.

var browser1 = Nightmare();
var browser2 = Nightmare();
