Install

``sh
npm install github-url-detection
`

`js
// This package is pure ESM
import * as pageDetect from 'github-url-detection';
`

Usage

`js
const href = 'https://github.com/refined-github/github-url-detection/issues/1';
if (pageDetect.isIssue(new URL(href))) { // Pass the URL as an URL object
alert('The passed URL is of an issue!')
}

if (pageDetect.isRepo()) { // Uses window.location.href by default
alert('You’re looking at a repo!')
}

if (pageDetect.isIssueOrPRList()) {
alert('You’re looking at a issues and PRs list!')
}
`

API

Most detections are URL-based while others need access to the current document. You can determine which ones are URL-based by looking at their signature: URL-based functions have a url parameter.

$3

By default, URL-based detections use the location global if you don't pass a url argument.

`js
if (pageDetect.isIssueOrPRList()) {
alert('You’re looking at a issues or PRs list!')
}
`

`js
if (pageDetect.isIssueOrPRList(new URL('https://github.com/refined-github/github-url-detection/pulls'))) {
alert('You’re looking at a issues or PRs list!')
}
`

Notice that the url parameter is not a plain string but it has to be a proper URL or location object.

$3

By default, document-based detections use the document global, which means they can only be used if you have the whole page, you can't just test any random URL string.

`js
if (pageDetect.isOrganizationProfile()) {
alert('You’re on an organization profile, like https://github.com/babel')
}
