+One of my oldest snippets is how to [Pretty print JSON](/snippets/pretty-print-json)
+in the shell. This method works great for simple things where you just need to get an idea
+of the JSON structure, it has the bonus of using python which you probably already have
+installed. The problem is when you want to do more complex tasks it is quite limited in terms of
+parsing. Thats where [jq](https://stedolan.github.io/jq) comes in
+
+```shell
+$ curl https://review-noticket-xxxxxxxx.eu/xxxxx/static/loadable-stats.json  | jq '.entrypoints .sharedHeader .assets' | rg --invert-match map`
+```
+
+Simply piping to [jq](https://stedolan.github.io/jq) pretty prints the JSON
+but by passing a query string, ex **".entrypoints .sharedHeader .assets"**,
+you dig into the JSON and easily get what you need. This is easily
+combinable with other shell utilities like in the example above which gets a
+list of asset URLs than uses ripgrep invert-match to clean out the source map
+URLs from the list. This is now my perfered way of working with JSON in the shell.
