puppeteer-interceptor POC

Given the following contexts:

• A script running in the main thread of a browser tab
• A script running in a WebWorker in a browser tab
• A script running in the background page of a browser extension

This project contains a proof of concept of using a fork of jsoverson/puppeteer-interceptor to:

• Intercept and fulfill requests sent from all contexts
• Intercept and edit responses received in all contexts

src/index.ts defines a small Puppeteer script that will:

• Intercept and immediately fulfill requests to data.txt
• Let requests to data2.txt passthrough to the server, but edit the response prior to completing the request

To run this script, run yarn pup.

testpage contains a small webpage that will make requests to data.txt and data2.txt, both from the main thread and from a web worker. To serve this page, run yarn serve.

my-browser-ext defines a small browser extension that will make requests to data.txt and data2.txt. This browser extension will be loaded when running src/index.ts.
