JSON to TypeScript interface

res.ts

Create TypeScript Interfaces with JSON samples

Inspired by wsdl2java, etc.

Current State:

Basic parsing is implemented. Read + fetch JSON, write to fs.

Known Issues:

Todo:

• Generate services
• Refactor
• Wrap up library into a CLI

Usage/Examples:

import { ParserFactory, GeneratorFactory, Http } from './lib/public_api';

const testJSON = `{
    "name": "test",
    "num": 1,
    "tt": {"p": 1},
    "numArr": [1,2,3],
    "test": ["a", "b"],
    "test2": [1, "a", true],
    "typedArrayTest": [{"a": 1}, {"a": 2}, {"a": 3}, {"a": "A"}],
    "booleanVal": true
}`;

const interfaceName = 'Test';

const parser = ParserFactory.create(testJSON, interfaceName);
const generator = GeneratorFactory.create();

const testParser = async () => {
    const res: string = await parser.dump();

    console.log(res);
}

const testParserWriteFile = async () => {
    const res: string = await parser.dump('./test');

    console.log(res);
}
testParser();
testParserWriteFile();

const testParserReadFile = async () => {
    await parser.loadFile('./src/tests/test.json', interfaceName);

    const res = await parser.dump();

    console.log(res);
}

testParserReadFile();

const http = new Http(parser);

const testHttp = async () => {
    const res: string = await http.transformResponse('Test', 'https://jsonplaceholder.typicode.com/todos/1');

    console.log(res);
}

testHttp();

// Creates project directory
generator.project();

// Creates types folder inside project directory
generator.types();

// Creates types inside type folder
parser.dump(generator.typesDir);
