Create-typescript-from-avro NPM

Avro Typescript

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

Install

npm install create-typescript-from-avro

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 * as fs from "fs";
import { avroToTypeScript, RecordType } from "create-typescript-from-avro";

const schemaText = fs.readFileSync(__dirname + "/example.avsc", "UTF8");
const schema: RecordType = JSON.parse(schemaText);
console.log(
  avroToTypeScript(schema, { convertEnumToType: false, removeNameSpace: true })
);

Cli

To use this package from the CLI you need the avro-to-ts which is added either locally or globally depending on how you installed the package. Options are:

--file or -f                - File or directory path(s) of .avsc files
-- convertEnumToType or -c  - See above
-- removeNameSpace or -r    - See above

Example:

avro-to-ts -f somefolder -f someotherfolder/someschema.avsc -c -r > model.ts

This example takes all the .avsc files recursively from somefolder and someschema.avsc, generates the appropriate .ts content and pipes it into model.ts
