Gracy is an API client library based on httpx that provides an extra stability layer with:

Retry logic
Logging
Connection throttling
Tracking/Middleware

In web scraping, Gracy can be a convenient tool for creating scraper based API clients.

Spidr is a Ruby gem that provides a simple and flexible way to spider and scrape websites. It allows you to easily navigate through a website, following links and scraping data as you go. It is built on top of Nokogiri, a popular Ruby gem for parsing and searching HTML and XML documents, and it provides a simple and intuitive API for defining and running web scraping operations.

One of the main features of Spidr is its ability to spider a website, following all the links on a page and visiting all the pages of a website. This allows you to easily and quickly scrape large amounts of data from a website, without having to manually specify which pages to visit.

In addition to its spidering capabilities, Spidr also provides a variety of other features that can simplify the web scraping process. It can automatically filter which links to follow and which pages to visit, it can handle cookies and authentication, and it can automatically store the scraped data in a database or file. It also provides a built-in support for parallelism and queueing to speed up the scraping process.

Example Use

```python # 0. Import import asyncio from typing import Awaitable from gracy import BaseEndpoint, Gracy, GracyConfig, LogEvent, LogLevel # 1. Define your endpoints class PokeApiEndpoint(BaseEndpoint): GET_POKEMON = "/pokemon/{NAME}" # 👈 Put placeholders as needed # 2. Define your Graceful API class GracefulPokeAPI(Gracy[str]): class Config: # type: ignore BASE_URL = "https://pokeapi.co/api/v2/" # 👈 Optional BASE_URL # 👇 Define settings to apply for every request SETTINGS = GracyConfig( log_request=LogEvent(LogLevel.DEBUG), log_response=LogEvent(LogLevel.INFO, "{URL} took {ELAPSED}"), parser={ "default": lambda r: r.json() } ) async def get_pokemon(self, name: str) -> Awaitable[dict]: return await self.get(PokeApiEndpoint.GET_POKEMON, {"NAME": name}) # Note: since Gracy is based on httpx we can customized the used client with custom headers etc" def _create_client(self) -> httpx.AsyncClient: client = super()._create_client() client.headers = {"User-Agent": f"My Scraper"} return client pokeapi = GracefulPokeAPI() async def main(): try: pokemon = await pokeapi.get_pokemon("pikachu") print(pokemon) finally: pokeapi.report_status("rich") asyncio.run(main()) ```

```ruby require 'spidr' Spidr.start_at("http://example.com") do |spider| spider.every_page do |page| puts "Visiting: #{page.url}" # Extract data from the page using Nokogiri doc = Nokogiri::HTML(page.body) title = doc.css("title").text puts "Title: #{title}" end end ```
