protobuf-validator v1.2.0

protobuf-validator

Validates objects against protocol buffer schemas

Motivation

Even if you don't use the binary serialization format, Protocol Buffer IDL is still a nice data modeling language, allowing you to define messages with typed fields, required/optional constraints, etc. This module allows you to validate JavaScript objects against protobuf schemas, which is useful if you have a JSON API but need to validate user submitted objects, for example.

Example

Assuming you have a file called models.proto:

message Person {
  required string name = 0;
  optional int32 age = 1;
}

var validate = require('protobuf-validator')('models.proto');

// valid
validate('Person', {
  name: 'Devon'
});

// throws "Person.name must be a valid string value"
validate('Person', {
  name: 123
});
