Input validation of REST requests using GoLang

Two things that have been of immense use are: -

Validating Data Structures And Variables In Golang

Regular Expressions 101

the latter of which has been very useful in terms of creating/testing/validating Regular Expressions ( aka RegExp ).

For me, the key thing is to be able to create validation rules within the JSON data structures, and then use the Go-Validator GoLang module/plugin/add-on: -

Specifically, I'm using the latest version 9 ( v9 ): -

"gopkg.in/go-playground/validator.v9"

Loving my job :-)
