HOW

목표: Intercept and customize subresource loading in JSDOM using ResourceLoader
패키지: jsdom 26.1.0
심벌: JSDOM
ResourceLoader
환경: node 22.23.2
생성일: 2026-08-28T06:56:19Z

ResourceLoader constructor accepts configuration options including userAgent, proxy, and strictSSL.
Instantiating JSDOM without configuring resources suppresses all external subresource fetching for scripts and stylesheets.
Attaching a custom ResourceLoader subclass intercepts subresource fetch requests and passes the requesting element reference in fetch options.
Returning a Buffer promise from ResourceLoader fetch resolves synthetic external script content and executes it within the JSDOM window context under runScripts dangerously.
Returning a Buffer promise from ResourceLoader fetch parses external stylesheets into document.styleSheets rules.
Returning null from ResourceLoader fetch silently blocks subresource fetching without throwing exceptions, emitting jsdomError, or firing element event handlers.
Rejecting the promise returned from ResourceLoader fetch triggers element onerror handlers and emits a jsdomError event to VirtualConsole.
