/function

Basic Example

This endpoint requires 2 parameters: code and context.
The code function is a javascript function which gets called with an object containing page and context.
page is the page object used by Puppeteer and is provided by us.

Code:

module.exports = async ({ page, context }) => {
  const { url } = context;
  await page.goto(url);

  const data = await page.content();

  return {
    data,
    type: 'application/html',
  };
};

Context:

{
  "url": "https://headlesstesting.com"
}

This simple example will run a Puppeteer script on our service and do the following:

• Start a Headless Chrome Browser (latest version) on our cloud.
• We will run the code you specified on the Headless Browser and pass the context to your function.
• In this example, the Puppeteer script will instruct the Headless Browser to navigate to our website and retrieve the HTML source.
• The return result will be returned to you (HTML source code) with a application/html content-type.
