Govalid is a data validation library that can validate most data types supported by golang. Custom validators can be used where the supplied ones are not enough.
import v "github.com/gima/govalid/v1"Create a validator:
schema := v.Object(
v.ObjKV("status", v.Boolean()),
v.ObjKV("data", v.Object(
v.ObjKV("token", v.Function(myValidatorFunc)),
v.ObjKV("debug", v.Number(v.NumMin(1), v.NumMax(99999))),
v.ObjKV("items", v.Array(v.ArrEach(v.Object(
v.ObjKV("url", v.String(v.StrMin(1))),
v.ObjKV("comment", v.Optional(v.String())),
)))),
v.ObjKV("ghost", v.Optional(v.String())),
v.ObjKV("ghost2", v.Optional(v.String())),
v.ObjKV("meta", v.Object(
v.ObjKeys(v.String()),
v.ObjValues(v.Or(v.Number(v.NumMin(.01), v.NumMax(1.1)), v.String())),
)),
)),
)Validate some data using the created validator:
if path, err := schema.Validate(data); err == nil {
t.Log("Validation passed.")
} else {
t.Fatalf("Validation failed at %s. Error (%s)", path, err)
}// Example of failed validation:
// Validation failed at Object->Key[data].Value->Object->Key[debug].Value->Number.
// Error (expected (*)data convertible to float64, got bool)You can also take a look at the "tests/" folder. (Sorry, but if you feel more documentation is needed, please open an issue.)

Original idea for jsonv (version 0 of this library, before rename) loosely based on js-schema, thank you.
