Show HN: Config-file-validator – CLI tool to validate all your config files
3 projects | news.ycombinator.com | 29 Sep 2023

I was expecting this to validate the configuration files are also valid for their use cases, not just valid JSON, TOML, etc.
If you're looking for that and Python is your jam, the library cerberus[0] is very good at it.

Do you think we need an open-source web scraping monitoring tool?

I wrote scrapy-test as a proof of concept for validating live pages for scrapy spiders if you're looking for some reference but if you're not using scrapy I'd recommend just adding validation tests using data validation tools like cerberus which is super underrated. I cover popular data validation techniques on this short blog I wrote if you want to learn more.
Can you suggest something more to grow in scraping?

Other than that, have you looked into testing scrapers? Since scrapers are working with highly dynamic data writing good tests is quite a challange. For example, for parser monitoring using cerberus is a very cool tool which allows you to define loose requirements like "phone number should always be 9 numbers" etc.
