🕷️ Xcrap API Client

Xcrap API Client is a package for the Xcrap Cloud service, designed for communicating with the API and handling authentication, management, and execution of scrapers and clients.

📦 Installation

Installation is straightforward. Just use your preferred dependency manager. Here is an example using NPM:

npm i @xcrap/api

🚀 Usage

If you're using a different server based on Xcrap Cloud (yes, we're open source), change the baseUrl in the Xcrap constructor.

Authentication

To access the routes, you must first authenticate. There are two ways to do this: using an email and password to get access tokens or using API Keys.

Using email and password:

import { Xcrap, AuthService } from "@xcrap/api"

;(async () => {
	const auth = new AuthService()

	const tokens = await auth.signIn({
		email: "YOUR_EMAIL",
		password: "YOUR_PASSWORD"
	})
	
	const xcrap = new Xcrap(tokens)
})();

Using API Keys:

import { Xcrap } from "@xcrap/api"

const xcrap = new Xcrap({ apiKey: "YOUR_API_KEY" })

Clients

Creating a Client

import { Xcrap, ClientType } from "@xcrap/api"

;(async () => {
	// Your way of instantiating Xcrap

	const client = await xcrap.clients.create({
		name: "A Cool Client",
		description: "A description for my Cool Client.", // optional
		type: ClientType.Axios // Check if the type is actually available for the pointed server
	})

	console.log(client) // Displays a class called Client that has the following methods: update, delete
})();

Finding a Client

const client = await xcrap.clients.findOne("YOUR_CLIENT_ID")

Finding Multiple Clients

const clients = await xcrap.clients.findMany()

You can also paginate. The default and maximum amount of results will depend on the targeted server, but you can define it explicitly:

const clients1 = await xcrap.clients.findMany({ page: 1, perPage: 20 })
const clients2 = await xcrap.clients.findMany({ page: 2, perPage: 20 })

Updating a Client

const updatedClient = await xcrap.clients.update("YOUR_CLIENT_ID", {
	name: "Updated Cool Client",
	description: "A updated description for my Cool Client.",
	type: "got_scraping" // Again, check if the type is available for the pointed server
})

Using a Client object:

await client.update({
	name: "Updated Cool Client",
	description: "A updated description for my Cool Client.",
	type: "got_scraping" // Again, check if the type is available for the pointed server
})

Deleting a Client

await xcrap.clients.delete("YOUR_CLIENT_ID")

Using a Client object:

await client.delete()

Scrapers

Creating a Scraper

import { Xcrap, ParsingModelFieldType } from "@xcrap/api"

;(async () => {
	// Your way of instantiating Xcrap

	const scraper = await xcrap.scrapers.create({
		name: "A Cool Scraper",
		description: "A description for my Cool Scraper", // optional
		defaultUrl: "http://example.com", // optional
		clientId: "YOUR_CLIENT_ID",
		parsingModel: {
			type: ParsingModelFieldType.Html, // Check if the type is available for the pointed server
			model: {
				title: {
					query: "title",
					extractor: "text" // Check if the extractor is available for the pointed server
				},
				title: {
					query: "title",
					extractor: "attribute:content" // Again, check if the extractor is available for the pointed server
				}
			}
		}
	})

	console.log(scraper) // Displays a class called Scraper that has the following methods: update, delete, execute
})();

Finding a Scraper

const scraper = await xcrap.scrapers.findOne("YOUR_SCRAPER_ID")

Executing a Scraper

const { data, metadata } = await xcrap.scrapers.executeOne("YOUR_SCRAPER_ID")

Using a Scraper object:

const { data, metadata } = await scraper.execute()

Executing a Dynamic Scraper

To be clear, a dynamic scraper is a scraper that isn't registered in the database; it's created dynamically in real-time. You can also create a Client with it or just pass the ID of an existing one.

Using an existing Client:

const { data, metadata } = await xcrap.scrapers.executeOneDynamic({
	url: "http://example.com",
	clientId: "YOUR_CLIENT_ID",
	parsingModel: {
		type: ParsingModelFieldType.Html, // Check if the type is available for the pointed server
		model: {
			title: {
				query: "title",
				extractor: "text" // Check if the extractor is available for the pointed server
			},
			title: {
				query: "title",
				extractor: "attribute:content" // Again, check if the extractor is available for the pointed server
			}
		}
	}
})

Dynamically creating a Client:

const { data, metadata } = await xcrap.scrapers.executeOneDynamic({
	url: "http://example.com",
	client: {
		type: "puppeteer_real_browser" // Check if the type is actually available for the pointed server
	},
	parsingModel: {
		type: ParsingModelFieldType.Html, // Check if the type is available for the pointed server
		model: {
			title: {
				query: "title",
				extractor: "text" // Check if the extractor is available for the pointed server
			},
			title: {
				query: "title",
				extractor: "attribute:content" // Again, check if the extractor is available for the pointed server
			}
		}
	}
})

Finding Multiple Scrapers

const scrapers = await xcrap.scrapers.findMany()

You can also paginate. The default and maximum amount of results will depend on the targeted server, but you can define it explicitly:

const scrapers1 = await xcrap.scrapers.findMany({ page: 1, perPage: 20 })
const scrapers2 = await xcrap.scrapers.findMany({ page: 2, perPage: 20 })

Updating a Client

const updatedScraper = await xcrap.SCRAPERS.update("YOUR_SCAPER_ID", {
	name: "Updated Cool Scraper",
	description: "A updated description for my Cool Scraper.",
	model: {
		title: {
			query: "title",
			extractor: "text" // Check if the extractor is available for the pointed server
		},
		title: {
			query: "title",
			extractor: "attribute:content" // Again, check if the extractor is available for the pointed server
		},
		heading: {
			query: "h1",
			extractor: "text"
		}
	}
})

Using a Scraper object:

await scraper.update({
	name: "Updated Cool Scraper",
	description: "A updated description for my Cool Scraper.",
	model: {
		title: {
			query: "title",
			extractor: "text" // Check if the extractor is available for the pointed server
		},
		title: {
			query: "title",
			extractor: "attribute:content" // Again, check if the extractor is available for the pointed server
		},
		heading: {
			query: "h1",
			extractor: "text"
		}
	}
})

Deleting a Scraper

await xcrap.scrapers.delete("YOUR_CLIENT_ID")

Using a Client object:

await scraper.delete()
