TypeScript Code Generator for Apache Avro Schema Types

Avro Typescript

A simple JS library to convert Avro Schemas to TypeScript interfaces.

The library can be run in node.js or the browser. It takes a Avro Schema as a JavaScript object (from JSON) and returns the TypeScript code as a string.

Usage

import { avroToTypeScript, RecordType } from "avro-typescript"

const schemaText = fs.readFileSync("example.avsc", "UTF8");
const schema = JSON.parse(schemaText) as RecordType;
console.log(avroToTypeScript(schema as RecordType));

Features

Most Avro features are supported, including:

• Enumerated Types
• Maps
• Named Records
• Mandatory and optional fields
• Unions
• Primitives

To-do

• Generate a function to set defaults as per the schema
• Add support for fixed
• Generate JSDocs from documentation
