I need to open a html file in browser using nodejs. I am trying to use "child_process". It does not seem to work. I do not want run a server/localhost to render. This is very simple html that needs to open.
import * as cpm from "child_process";
cpm.exec(`open somefilename.html`);

I am using puppeteer in my nodejs application to convert html file into pdf. This is working fine in my local server and pdf is getting generated. But this is not working in cPanel. I am getting error similar to this. I tried everything mentioned on that but nothing works.
I tried setting the executable path of chrome in puppeteer in cpanel but in vain. Errpr =>
Failed to launch the browser process!
/home/xxx/public_html/xxx/node_modules/puppeteer/.local-chromium/linux-1002410/chrome-linux/chrome: error while loading shared libraries: libatk-1.0.so.0: cannot open shared object file: No such file or directory
I tried different packages like html-pdf and node-pdf-generator. But the problem is I have designed some ejs templates according to chrome and then I am generating html files from these ejs templates. After that I am saving the pdf file in buffer and uploading this buffer to google bucket.
Flow: ejs templates -> html file -> pdf buffer -> stream buffer to gc
bucket
In other packages I am facing these issues:
Either the template is not coming as expected
Or The package has no option of storing generated pdf file in buffer.
Any solution or a different library?
I am writing automation using Nightwatch node js. I have a test for uploading a file in my application and testing it locally works perfectly. However, when I test it using BrowserStack, BrowserStack cannot access the file in my local machine.
I have also tried setting FileDetector but it gives error saying setFileDetector is not a function on browser object.
I know this function is available for selenium driver object but I am javascript browser object for writing test scripts.
browser.setFileDetector(new remote.FileDetector());
I see that you want to perform the File Upload Operation for a file available on your local machine. You can review the link: https://www.browserstack.com/automate/node#enhancements-uploads-downloads for more details.
You all know open npm package: https://www.npmjs.com/package/open
Using this package, one can write the following code:
var open = require('./node_modules/open/lib/open.js')
open('http://www.cnn.com')
and activating it by:
$ node app.js
will open a browser window of cnn.com.
I want my script to open this site and inject some code to the console. I mean that the browser will behave like I clicked F12, went to 'console' tab and typed in console the code:
alert('Hello World')
Do you know how to do it?
The open module is used to "Open a file or url in the user's preferred application."
It can open the preferred application (a browser in this case) but it cannot control it. In fact, it doesn't even know what browser will that be (or even if that will be a browser).
What you are asking for can be achieved with tools like PhantomJS ("PhantomJS is a headless WebKit scriptable with a JavaScript API."), Nightmare.js ("A high-level browser automation library.") or CasperJS ("Navigation scripting & testing for PhantomJS and SlimerJS"), see:
http://phantomjs.org/

I have found how to upload a file using Java: (How to handle windows file upload using Selenium WebDriver?)
I want to know how upload file using Node.js?
I need a comandline tool (or Javascript/PHP, but i think commandline is the one way) for render and get the rendered content of URL, but the important its I need to renderer the Javascript not only the CSS/Html/images.
For example command like: "renderengine http://www.google.es outputfile.html" and the content of the web (parsed html and javascript executed) isa saved in outputfile.html.
I need this because i need to take the result of a full javascript website like grooveshark, the site load all using javascript/ajax and the crawlers dont find nothing, only basic HTML empty template (because is loaded after using ajax/javscript)
Exists any browser engine for linux with support to Javascript (for example V8) that output the result for save in files?

PhantomJS (first suggested by nvuono) : can export the rendered page as non-HTML (pdf, png...). PhantomJS development is suspended until further notice (more details).
Closely related: SlimerJS, CasperJS
And there are many Python web scraping libraries:
Scrapy
pyspider
ghost.py
splinter
Try phantomjs from www.phantomjs.org and you can easily modify the included rasterize.js to export the rendered HTML. It's based on webkit and does full evaluation of your target site's javascript, allowing you to adjust timeouts or execute your own code first if you wish. I personally use it to save hardcopy HTML file version of fully-rendered knockout.js templates.
It executes javascript so I just did something like this and saved the console output to a file:
var markup = page.evaluate(function(){return document.documentElement.innerHTML;});
console.log(markup);
phantom.exit();
