# URL Filter The `allowedURLs` and `blockedURLs` config options allow you to specify a list of URL patterns (in form of regular expressions) which are accessible or blocked during scraping. ```javascript export const options = { url: "http://example.com/", allowedURLs: ["/articles/.*", "/authors/.*"], blockedURLs: ["/authors/admin"], // ... }; ``` ### `allowedURLs` This config option controls which URLs are allowed to be visted during scraping. When no value is provided all URLs are allowed to be visited if not otherwise blocked. When a list of URL patterns is provided, only URLs matching one or more of these patterns are allowed to be visted. Example: ```javascript export const options = { url: "http://example.com/", allowedURLs: ["/products/"], }; ``` ### `blockedURLs` This config option controls which URLs are blocked from being visted during scraping. When a list of URL patterns is provided, URLs matching one or more of these patterns are blocked from to be visted. Example: ```javascript export const options = { url: "http://example.com/", blockedURLs: ["/restricted"], }; ```
