types-json
Types and type guards for JSON values.
If I should maintain this repo, please ⭐️
DM me on Twitter if you have questions or suggestions.
This package is specifically for when you have a value that you know is valid JSON - ex: the result of JSON.parse.
It includes type guards for each of the JSON types, as well as matching types.
