generate-runtypes

A code generator for Runtypes types

This library aims to provide an intuitive and easy way to generate Runtypes types. This package aims to be a great utility for a conversion package (e.g. JSON Schema to Runtypes).

We are thankful for all help with adding new functionality, fixing issues, or improve the package. Feel free to open issues and pull requests ❤️

Example

import { generateRuntypes } from 'generate-runtypes';

const sourceCode = generateRuntypes([
  {
    name: 'Comment',
    type: {
      kind: 'record',
      fields: [
        { name: 'author', type: { kind: 'string' } },
        { name: 'body', type: { kind: 'string' } },
        { name: 'timestamp', type: { kind: 'number' } },
      ],
    },
  },
  {
    name: 'Post',
    export: true,
    type: {
      kind: 'record',
      fields: [
        { name: 'title', type: { kind: 'string' } },
        { name: 'body', type: { kind: 'string' } },
        { name: 'author', type: { kind: 'string' } },
        {
          name: 'comments',
          type: { kind: 'array', type: { kind: 'named', name: 'Comment' } },
        },
      ],
    },
  },
]);

The generated code looks like this after formatting:

import * as rt from 'runtypes';

const Comment = rt.Record({
  author: rt.String,
  body: rt.String,
  timestamp: rt.Number,
});

export const Post = rt.Record({
  title: rt.String,
  body: rt.String,
  author: rt.String,
  comments: rt.Array(Comment),
});
