Exercise 8: Schema-Level Validation

8. Schema-Level Validation

Context

Types stop at string; they cannot say which strings are valid. protovalidate puts those rules in the schema as options, so every language enforces the same ones.

Task

Import buf/validate/validate.proto, require email to be a valid email address, and require age to be at least 18.

Validation

schema.proto

Valid Schema

syntax = "proto3";

package practice;

// Signup is submitted when a new account is created
message Signup {
  string email = 1;
  uint32 age = 2;
}

Evaluation checks

Imports 'buf/validate/validate.proto'.

Field 'email' requires a valid email address.

Field 'age' must be at least 18.
