Usage

First we have to define a reference object that describes types, defaults, and a $resolve method (normalizer).

const defaultPlanet = {
  name: "earth",
  specs: {
    gravity: {
      $resolve: (val) => Number.parseFloat(val),
      $default: "9.8",
    },
    moons: {
      $resolve: (val = ["moon"]) => [val].flat(),
      $schema: {
        title: "planet moons",
      },
    },
  },
};

API

resolveSchema

import { resolveSchema } from "untyped";

const schema = await resolveSchema(defaultPlanet);

Output:

{
  "properties": {
    "name": {
      "type": "string",
      "default": "earth"
    },
    "specs": {
      "properties": {
        "gravity": {
          "default": 9.8,
          "type": "number"
        },
        "moons": {
          "title": "planet moons",
          "default": ["moon"],
          "type": "array",
          "items": [
            {
              "type": "string"
            }
          ]
        }
      },
      "type": "object"
    }
  },
  "type": "object"
}

generateTypes

import { resolveSchema, generateTypes } from "untyped";

const types = generateTypes(await resolveSchema(defaultPlanet));

Output:

interface Untyped {
  /** @default "earth" */
  name: string;

  specs: {
    /** @default 9.8 */
    gravity: number;

    /**
     * planet moons
     * @default ["moon"]
     */
    moons: string[];
  };
}

generateMarkdown

import { resolveSchema, generateMarkdown } from "untyped";

const markdown = generateMarkdown(await resolveSchema(defaultPlanet));

Output:

# `name`

- **Type**: `string`
- **Default**: `"earth"`

# `specs`

## `gravity`

- **Type**: `number`
- **Default**: `9.8`

## `moons`

- **Type**: `array`
- **Default**: `["moon"]`
