oust

Extract URLs to stylesheets, scripts, links, images or HTML imports from HTML

Install

npm install --save-dev oust

Usage

First include:

const oust = require("oust");

Resource links can then be extracted from either files:

Extract stylesheets references <link rel="stylesheet">

const hrefs = oust(htmlString, "stylesheets");

Extract stylesheets references with media print <link rel="stylesheet" media="print">

const hrefs = oust(htmlString, "stylesheets", (i, $el) => {
    return $el.attr("media") === "print";
});

Extract script references <script src>

const srcs = oust(htmlString, "scripts");

Extract HTML imports <link rel="import">

const hrefs = oust(htmlString, "imports");

Extract style preload references <link rel="preload" as="style">

const hrefs = oust(htmlString, "preload");

Extract URL references <a href>

const srcs = oust(htmlString, "links");

Extract image source references <img src>

const srcs = oust(htmlString, "images");

Extract inline styles <style>...</style>

const styles = oust(htmlString, "styles");

Extract preload and stylesheet references combined

const hrefs = oust(htmlString, ["preload", "stylesheets"]);

Extract cheerio elements alongside the value

Usefull for post processing/filtering as you get an array of matched elements with cheerio convenience syntax (e.g. $el.attr())

const srcs = oust.raw(htmlString, '...');

 -> [
    {value: '...', $el: '...'},
    {value: '...', $el: '...'},
    ...
 ]
