About React Component Crawler
Ever needed to peek under the hood of a live React app to see what data a component is actually holding? The React Component Crawler does exactly that. You give it a list of URLs and point it to the components you're interested in using a CSS selector. It then navigates those pages, finds the specified components, and extracts their current state and props for you. This is incredibly useful for debugging complex applications, automating data collection from modern web apps, or even for competitive analysis where you need to understand how a site structures its internal data. Instead of manually inspecting elements or digging through network tabs, this tool programmatically pulls the state directly from the rendered components. It saves a ton of time, especially when you need to check multiple pages or components. I've used it to monitor data changes on dashboards and to verify that components are receiving the correct props during development. Just configure your target and let it handle the extraction.

Documentation
React Component Crawler
Extracts the internal state from React components on live websites. Useful for scraping data that's embedded in component state, such as options hidden behind dropdowns, data from complex interactive elements, or information loaded in non-standard ways.
Key Features
- State Extraction: Directly pulls the
stateobject from matched React components. - CSS Selector Targeting: Use any CSS selector to pinpoint the specific components you want to inspect.
- Automated Crawling: Processes a list of URLs to extract data at scale.
- Handles Dynamic Content: Effective for data rendered client-side by React that traditional HTML scraping misses.
How to Use
- Provide URLs: Input the list of web pages to crawl.
- Define a CSS Selector: Specify the selector that matches your target React components. You can test selectors in your browser's DevTools.
- Run the Actor: The crawler visits each page and extracts the component state.
- Review Output: Check the extracted data. If results are incorrect, refine your CSS selector.
Common troubleshooting step: Most extraction issues are due to an imprecise CSS selector. Ensure your selector uniquely identifies the intended components.
Input/Output
Input: Configure the actor via its input schema, which defines the required URLs and CSS selector.
