Easily parse & consume microdata
npm i micro-parse
import microdataParse from "micro-parse";
const html = '<div itemscope itemtype="https://schema.org/SoftwareApplication">...</div>'
console.log(microdataParse(html));
The above should produce an object with the following structure, mapping identically to the microdata hierarchy of its source data:
{ scope: 'https://schema.org/SoftwareApplication', metadata: {...}, children: [...] }
In the above, scope indicates a defined microdata scope, metadata represents all data associated with the given scope level, and children includes all sub-scopes (array members are objects repeating the above structure)
In unusual cases where metadata is updated client-side, we can allow script execution as follows:
const html = '<div itemscope itemtype="https://schema.org/SoftwareApplication">...</div>'
const options = { runScripts: "dangerously" };
console.log(microdataParse(html, options));
Note that you incur some risk when running unknown scripts. Warning from JSDOM docs:
...this is also highly dangerous when dealing with untrusted content. The jsdom sandbox is not foolproof, and code running inside the DOM's <script>s can, if it tries hard enough, get access to the Node.js environment, and thus to your machine.
All options passed will be relayed to JSDOM – as such, all JSDOM-supported options are available. Absence of the options argument will instead leverage node-html-parser, often yielding performance gains north of 50%.
