ProtoBuff Data Types Schema Parser

A schema parser for Protocol Buffers data types. For ProtoBuff 2 and 3 schemas.

There is no explicit distinction between ProtoBuff 2 and 3. You dont have to expect any errors if your schemaFormat is application/vnd.google.protobuf;version=2 defined, but your schema is proto3.

Support for AsyncApi schema versions: 2

Compatible with: @asyncapi/parser 1.x (tested with: 1.18.1)

This package is browser-compatible.

Installation

npm install @asyncapi/proto-schema-parser

Usage

const parser = require('asyncapi-parser')
const protoParser = require('@asyncapi/proto-schema-parser')

                optional string label = 3;
            }

parser.registerSchemaParser(protoParser)
