## usage

1. open extensions options page

2. open devtools console

3. use provided `tabgod()` function

   1. choose execution targets by writing a filter function that will

      include/excluce tabs based on defined criteria

      - https://developer.chrome.com/docs/extensions/reference/api/tabs#type-Tab

   2. write any js to execute in world of targeted tabs

```js

tabgod(

  (tab) => tab.url.includes("example.org"),

  () => document.body.style.background = "pink",

);

```

## notes on first release

- initial idea was to make tabgod function available in all devtools consoles

  for easy and direct access for developers right from every console

- the implementation added tabgod to the global window object

- however this introduced a serious security issue, since this has made the

  function available to websites also, allowing them to interact with other tabs,

  destroying the idea of secure tab origins

- thanks to

  [danielsmc pointing it out](https://github.com/devidw/tabgod/issues/1#issue-2124285330)

- this has been immediately addressed by moving the function only to the options

  page of the extension, and not accepting external connections in the service
