You will need to provide more info than that.

What are you actually trying to achieve? What is the end goal?

If you simply need to GET data from a web page, it may be simpler to use HTTP Request node.

See **http request** examples in the cookbook: [Node-RED Cookbook : Node-RED](https://cookbook.nodered.org/#http-requests)

Again, you can use the http request node to get the HTML of a page

Unfortunately not, I don't use it.

If you want more help you will need to provide much more information e.g...

- What version of node-js is installed on the node-red server?
- What version of node-red are you using?
- What OS are you running node-red on?
- Does the node-red server have internet access?
- What errors are you seeing?
  - can you provide logs? (text format please, not screenshot)

THe difference of course being that Puppeteer will execute the page's JavaScript whereas the request node will not.

Yes, that is correct, however every web page gets its information from _somewhere_- often, that is from an additional request to an HTTP endpoint.

For example, when you grab the HTML using HTTP Request, it may not include details like the PRICE or the QUANTITY. Typically these are updated by JavaScript. HOWEVER: if you watch the `network` tab in the browser developer tools you can often find where these values come from and simply request the `json` or `xml` instead of running puppeteer.
