Simple Tab Connector

About

Simple Tab Connector or STC is a minimalistic web scraping tool that allows you to extract content from another web page and use it on your web page.

To create a connection:
1) open a tab with a web page that should use the data of another;
2) click on the extension icon, a pop-up window with input and output buttons should appear;
3) click the “Output” button, it should be replaced by the host of the current web page;
3) open a tab with a web page that should send data to another;
4) click on the extension icon, a pop-up window with input and output buttons should appear;
5) press the “Input” button, it should be replaced by the host of the current web page;
6) When the input and output tabs are specified, you should see a green counter (this indicates the success of the data transfer).


STC does not provide a user interface to display the received content. Instead, it raises custom window events:
1) the connection event (type - 'connection', detail - 'on'/'off') notifies about  connection status between tabs;
2) the mutation event (type - 'mutation', detail contains html) notifies about DOM changes on the input page;
3) the reloading request event (type - 'requestReloading') allows to reload the input page that could be useful to fix rendering issue sometimes;
4) the reloading success event (type - 'reloadingDone') notifies that the input page is ready after a reload;
5) the data request event (type - 'requestData', detail contains an object with url) allow to request additional data from the input page via fetch API;
6) the data response event (type = 'responseData', detail contains response of data request) allow to fetch requested data after invocation of the previous event.
7) the message event (type = 'wsData') allow to get websocket messages from the input tab as byte array.

You can handle or raise these events in your JavaScript code. Good luck.
