js-path-util v0.1.2

JSPath

This is a small browser util, similar to the Google Chrome Dev Tools: Copy -> Copy JS path menu option when right clicking an element inside the element inspector.

This util is more catered towards tools like scrapers that want a JSPath selector that works on every page reload.

Features

These features make it different from the chrome dev tools.

• Takes into account scoped elements, uses data-tag-name attribute as selector if one exists, as the tag name changes on each page reload
• Doesn't use any attributes like id, as they can be auto-generted, and change on each page reload
• Just like dev tools, it goes across shadow boundaries

Not implemented:

• Going across iframes

Usage

npm i js-path-util

import { jsPath } from 'js-path-util';

jsPath(fooElement);

Or apply it to the window

import 'js-path-util/src/apply-js-path-to-window.js';

window.jsPath(fooElement)

Or copy-paste the JS from unpkg into your Dev Tools console and use it:

jsPath($0)

In Chrome Dev Tools in combination with $0 helper:

Demo

To see a demo, clone this repository, go into the root folder:

npm i && npm start

The demo also functions as a non-automated smoke test, I can add real tests if this util seems to be useful to people.
