ts-validators

This is not a library, this is just a collection of validator functions I frequently use and I'm putting here for sharing purposes. If you're using the jet-schema library you might find this collection of functions pretty useful.

All the validator functions are in the ./src/validators.ts file.

Abbreviations used in naming functions:

• Opt optional, (value | undefined)
• Nul nullable, (value | null)
• Nish nullish, (value | null | undefined)

parse: A really special function

• parse iterates an object using a provided schema and validator-functions to validate each property. Then it calls an error-callback if supplied one, and returns undefined if the parse fails or the argument value (properties in the schema not included) if it passes.
• Works recursively.
• Return value generated from schema properties + validator-function type-predicates
• I use parse when validating express request objects. If you want to see an example of parse in action you can checkout this repo: https://github.com/seanpmaxwell/express5-typescript-template/blob/master/src/routes/common/index.ts
