protofake

Library to generate fake data for Protobuf messages. Uses faker-js to generate values based on Protobuf field types and field names.

Usage

import { fake } from "protofake";
import { UserSchema } from "./gen/example_pb";

const user = fake(UserSchema);
user.firstName; // "Claude"
user.lastName; // "Mueller"
user.active; // true

The function fake takes a message descriptor as an input, and returns a new instance with all fields populated with fake data.

Status

Work in progress. Things to do:

• Publish on npmjs.com
• Honor protovalidate options
• Provide option to only partially populate optional fields
• Special case google/type/localized_text.proto
• Special case google/type/money.proto
