crawlee VS TypeScript

In this guide, we'll be extracting information from Amazon product pages using the power of TypeScript in combination with the Cheerio and Crawlee libraries. We'll explore how to retrieve and extract detailed product data such as titles, prices, image URLs, and more from Amazon's vast marketplace. We'll also discuss handling potential blocking issues that may arise during the scraping process.

Previously, the Apify SDK offered a blend of crawling functionalities and Actor building features. However, a recent update separated these functionalities into two distinct libraries: Crawlee and Apify SDK v3. Crawlee now houses the web scraping and crawling tools, while Apify SDK v3 focuses solely on features specific to building Actors for the Apify platform. This distinction allows for a clear separation of concerns and enhances the development experience for various use cases.

v3.1 added an error tracker for analyzing and summarizing failed requests.

Closest I found was https://crawlee.dev/ for Javascript/Typescript although still seems not on the level of scrapy. I didn't try it.

Also, you can go even further and develop your own web scraper with Crawlee, a Node.js library that helps you pass those challenges automatically using Puppeteer or Playwright. Crawlee helps you build reliable scrapers fast. Quickly scrape data, store it, and avoid getting blocked with headless browsers, smart proxy rotation, and auto-generated human-like headers and fingerprints.

https://crawlee.dev/ its very good, you can easily run your spiders in cloud with apify, and nodejs/puppeteer has many advantages than python/selenium

Apify is a platform for web scraping that helps the developer starting from the coding, having developed its open-source NodeJs library for web scraping called Crawlee. Then on their platform, you can run and monitor the scrapers and also finally sell your scrapers in their store.

You can use our open source tools (not only this one, but also Crawlee for example) to build your scrapers and run them on your computer, and then if you need to run them in the cloud, you can upload them to the Apify platform and run them there. Our free tier is good enough for smaller web scraping and automation projects, and if you need more compute resources or proxies, you can go for one of our paid tiers.

Comfortable scraping and crawling with Puppeteer is better done together with another library. This library is called Crawlee, and it's also free and open-source, just like Puppeteer. Crawlee wraps Puppeteer and grants access to all of Puppeteer's functionality, but also provides useful crawling and scraping tools like error handling, queue management, storages, proxies or fingerprints out of the box.

Regular expressions are part of the language, so it's not so unreasonable that TypeScript should parse them and take their semantics into account. Indeed, TypeScript 5.5 will include [new support for syntax checking of regular expressions](https://github.com/microsoft/TypeScript/pull/55600), and presumably they'll eventually be able to solve the problem the GP highlighted on top of those foundations.

Dedicated syntax for creating unique subsets of a type that denote a particular refinement is a longstanding ask[2] - and very useful, we've experimented with implementations.[3]

I don't think it has any relation to runtime type checking at all. It's refinement types, [4] or newtypes[5] depending on the details and how you shape it.

Learning Curve and Developer Tooling sCrypt is an embedded Domain Specific Language (eDSL) based on TypeScript. It is strictly a subset of TypeScript, so all sCrypt code is valid TypeScript. TypeScript is chosen as the host language because it provides an easy, familiar language (JavaScript), but with type safety. There’s an abundance of learning materials available for TypeScript and thus sCrypt, including online tutorials, courses, documentation, and community support. This makes it relatively easy for beginners to start learning. It also has a vast ecosystem with numerous libraries and frameworks (e.g., React, Angular, Vue) that can simplify development and integration with Web2 applications.

As a JavaScript or TypeScript developer, you might have come across the terms type and interface when working with complex data structures or defining custom types. While both serve similar purposes, they have distinct characteristics that influence when to use them. In this blog post, we'll delve into the differences between types and interfaces in TypeScript, providing examples to aid your understanding.

TypeScript helps you in many ways in the context of a JavaScript app. It makes it easier to consume interfaces of any type.
