Utility for converting JSON Schema to MobX State Tree types.

JSON Schema: http://json-schema.org/

MobX State Tree Types: https://github.com/mobxjs/mobx-state-tree#types-overview

Use Case:

Let's say we had an event schema that looked like this:

{
  type: 'object',
  title: 'Event',
  properties: {
    title: {
      type: 'string'
    },
    public: {
      type: 'boolean',
      default: false
    },
    time: {
      type: 'object',
      properties: {
        start: {
          type: 'string',
          format: 'datetime'
        },
        end: {
          type: 'string',
          format: 'datetime'
        }
      },
      required: ['start']
    }
  },
  required: ['title', 'public']
}

Should output:

types.model('Event', {
  title: types.string,
  public: types.optional(type.boolean, false),
  time: types.maybe({
    start: types.Date,
    end: types.maybe(types.Date)
  })
});

Usage:

$ npm install --save jsonschema-to-mobx-state-tree

const { types } = require('mobx-state-tree');
const jsonSchemaToTypes = require('jsonschema-to-mobx-state-tree')(types);

jsonSchemaToTypes(myJSONSchema);

We can additionally pass on an onNode function to be called every node, whose response will be used in place of the node that would have been returned in the conversion.

jsonSchemaToTypes(myJSONSchema, (result, {node, meta, typeMap}) => {
  // Log out result, node, meta, and typeMap to see options.
});
