Methods
enqueueLinks
This function automatically finds and enqueues links from the current page, adding them to the RequestQueue currently used by the crawler.
Optionally, the function allows you to filter the target links' URLs using an array of globs or regular expressions and override settings of the enqueued Request objects.
Check out the Crawl a website with relative links example for more details regarding its usage.
Example usage
async requestHandler({ enqueueLinks }) {
await enqueueLinks({
globs: [
'https://www.example.com/handbags/*',
],
});
},Parameters
optionaloptions: EnqueueLinksOptions
All
enqueueLinks()parameters are passed via an options object.
Returns Promise<BatchAddRequestsResult>
Promise that resolves to BatchAddRequestsResult object.

got-scraping, allowing to override the request options on the fly.This is handy when you work with a browser crawler but want to execute some requests outside it (e.g. API requests). Check the Skipping navigations for certain requests example for more detailed explanation of how to do that.
async requestHandler({ sendRequest }) {
const { body } = await sendRequest({
// override headers only
headers: { ... },
});
