Build a module that scrapes html element info/dimensions after JS has been extracted.

We are building a scraping tool, and we need some assistance with executing Javascript and getting some data back. You can use any common technology stack you like. We need a simple HTTP API that will help us with scraping Javascript websites. The requirements are: A] There will be three endpoints: Endpoint 1: api/page-content?url={webpageURL} Take a web page URL, execute the Javascript then return the HTML that results. Endpoint 2: api/image-dimensions?url={webpageURL}&imgUrl={imageURL} Take a webpage URL and an image URL, and execute the Javascript, then return a JSON object with the height and width of the specified image as displayed on the page. Note: this is not the actual height and width of the image file, but the display dimension of the image object on the page. Naturally the exact value depends on the screen resolution. You can set the screen resolution to something like 1200x1600 Often the actual image is much larger than the displayed image, we only want the displayed dimensions (in pixels). Endpoint 3: api/largest-image?url={webpageURL} Take a web page URL, execute the JS, then returns the imageURL, height and with of the largest image The largest image is the one where the displayed size= height * width is the greatest. Again height and width are based on the displayed dimensions, not the actual height/width. C] There should be no need for adding anything to the server. We just deploy the app in a docker container and then it should run. If you need to for example add a .exe file to the server, this is not a suitable solution. D] It should be able to use a proxy server for IP rotation. we will provide the host and login details of the proxy server for testing. E] There should be simple authentication to provide unwanted access. But the authentication params should be hardcoded/in a config file, and not require database access. We will need you to write and deploy the application - most likely we can host it with our PAAS company (depends on your chosen stack), otherwise it will be deployed on Digital Ocean (we will provide the account). For us, this is very urgent so speed is important. In your bid please specify the tech stack (or stacks) you are able to use, ask any questions you may have, and specify approximately how long this will take - or at least when you can start. Look forward to working with you.
