tsog

A lightweight package using typescript compiler API to generate an object or value from a type or interface.

Installation

$ npm i -D tsog

Usage

Configurating

The module uses the path to your typescript files to look for specific type references. It can also take a js file, from which it will compile a declaration file and read the types from it.

import tsog from 'tsog';

tsog.defineFiles(['type.d.ts', 'uncompiled.js'])

If you use this package to help you test your app with jest or vitest, call the method on your test setup file.

Generating

type.d.ts

export interface SomeObjectInterface {
    name: string
    id: number,
    nested: SomeOtherObjectInterface
}

export interface SomeOtherObjectInterface {
    name: string
}

app.test.ts

import tsog from 'tsog';

const object = tsog.generate('SomeObjectInterface');

// you can infer a type
const object = tsog.generate<SomeObjectInterface>('SomeObjectInterface');

// and override the results
const object = tsog.generate('SomeObjectInterface', {
    overrides: {
        'nested.name': 'IPreferThisName'
    }
});
