Apify SDK
Apify SDK provides the tools required to run your own Apify Actors. The crawlers and scraping related tools, previously included in Apify SDK (v2), have been split into a brand-new module - crawlee
, while keeping the Apify specific parts in this module.
Would you like to work with us on Crawlee, Apify SDK or similar projects? We are hiring Node.js engineers.
Upgrading from v2
A lot of things have changed since version 2 of the Apify SDK, including the split of the crawlers to the new crawlee
module. We've written a guide to help you easily migrate from v2 to v3. Visit the Upgrading Guide to find out what changes you need to make (especially the section related to this very Apify SDK), and, if you encounter any issues, join our Discord server for help!
Quick Start
This short tutorial will set you up to start using Apify SDK in a minute or two. If you want to learn more, proceed to the Apify Platform guide that will take you step by step through running your Actor on Apify's platform.
Apify SDK requires Node.js 16 or later. Add Apify SDK to any Node.js project by running:
npm install apify crawlee playwright
For this example, we'll also install the
crawlee
module, as it now provides the crawlers that were previously exported by Apify SDK. If you don't plan to use crawlers in your Actors, then you don't need to install it. Keep in mind that neitherplaywright
norpuppeteer
are bundled withcrawlee
in order to reduce install size and allow greater flexibility. That's why we manually install it with NPM. You can choose one, both, or neither.
There are two ways to initialize your Actor: by using the Actor.main()
function you're probably used to, or by calling Actor.init()
and Actor.exit()
manually. We prefer explicitly calling init
and exit
.
Using Actor.init()
and Actor.exit()
import { Actor } from 'apify';
import { PlaywrightCrawler } from 'crawlee';
await Actor.init()
const crawler = new PlaywrightCrawler({
async requestHandler({ request, page, enqueueLinks }) {
// Extract HTML title of the page.
const title = await page.title();
console.log(`Title of ${request.url}: ${title}`);
// Add URLs that point to the same hostname.
await enqueueLinks();
},
});
await crawler.run(['https://crawlee.dev/']);
await Actor.exit();
Using Actor.main()
import { Actor } from 'apify';
import { PlaywrightCrawler } from 'crawlee';
await Actor.main(async () => {
const crawler = new PlaywrightCrawler({
async requestHandler({ request, page, enqueueLinks }) {
// Extract HTML title of the page.
const title = await page.title();
console.log(`Title of ${request.url}: ${title}`);
// Add URLs that point to the same hostname.
await enqueueLinks();
},
});
await crawler.run(['https://crawlee.dev/']);
});
