A gRPC crawler that's very fast.
Make sure to have Rust installed or Docker.
This project requires that you start up another gRPC server on port 50051 following the proto spec.
cargo run or docker compose upYou can install easily with the following:
The crate is available to setup a gRPC server within rust projects.
sh
cargo install website_crawler
You can use also use the docker image at a11ywatch/crawler.
Set the CRAWLER_IMAGE to darwin-arm64 to get the native m1 mac build that runs more performant.
yml
crawler:
container_name: crawler
image: "a11ywatch/crawler:${CRAWLER_IMAGE:-latest}"
ports:
- 50055
We also release the package to npm @a11ywatch/crawler.
sh
npm i @a11ywatch/crawler
After import at the top of your project to start the gRPC server or run node directly against the module.
ts
import "@a11ywatch/crawler";
This crawler is optimized for reduced latency and performance as it can handle over 10,000 pages within seconds.
In order to receive the links found for the crawler you need to add the website.proto to your server.
This is required since every request spawns a thread. Isolating the context drastically improves performance (preventing shared resources / communication ).
If you need help implementing the gRPC server to receive the pages or links when found check out the gRPC node example for a starting point .
