Doubter × JSON Schema 

Converts Doubter shapes from and to JSON schemas.

Warning This project is at the early development stage.

npm install --save-prod @doubter/json-schema

Define a shape:

import * as d from 'doubter';

const shape = d.object({
  foo: d.string().optional(),
  bar: d.number().gt(10)
});
// ⮕ Shape<{ foo: string | undefined, bar: number }>

const schema = toJSONSchema(shape);

The schema is a JSON schema object:

{
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "type": "object",
  "properties": {
    "foo": {
      "oneOf": [
        { "type": "null" },
        { "type": "string" }
      ]
    },
    "bar": {
      "type": "number",
      "exclusiveMinimum": 10
    }
  },
  "required": ["bar"]
}
