Types

Usage examples below show you how to pass them in Model classes.

string

import { Types, createModel } from 'tydel';

const Todo = createModel({
  title: Types.string
});

bool

For boolean values:

import { Types, createModel } from 'tydel';

const Todo = createModel({
  completed: Types.bool
});

number

import { Types, createModel } from 'tydel';

const Person = createModel({
  age: Types.number
});

array

Even though this type exists in the API, you are highly advised to use Collection for any array-like values.

import { Types, createModel } from 'tydel';

const Author = createModel({
  books: Types.array
});

object

Even though this type exists in the API, you are highly advised to use Model for any object-like values.

import { Types, createModel } from 'tydel';

const Person = createModel({
  address: Types.object
});

And for defining schema of nested object, you can use object.of:

const Person = createModel({
  address: Types.object.of({
    street: Types.string,
    city: Types.string,
    postalCode: Types.number,
    country: Types.string
  });
});

enum

If you want the value to be one of the pre-defined list of values:

import { Types, createModel } from 'tydel';

const Book = createModel({
  category: Types.enum([
    'history',
    'fiction',
    'romance'
  ])
});

And if you want the enum to be of specific types, you can use enum.of:

const Book = createModel({
  category: Types.enum.of([
    Types.string,
    Types.number
  ])
});

uuid

If the value is expected to be an UUID:

import { Types, createModel } from 'tydel';

const Book = createModel({
  id: Types.uuid
});

Example UUID value: 27961a0e-f4e8-4eb3-bf95-c5203e1d87b9.

any

If the value can be of any type. You are advised not to use this:

import { Types, createModel } from 'tydel';

const Person = createModel({
  bio: Types.any
});

model

Models can embed other models too:

import { Types, createModel } from 'tydel';

const Person = createModel({
  address: Types.model
});

If you want to be more strict about which Model class can be embedded, use model.of:

const Address = createModel({
  street: Types.string,
  city: Types.string
});

const Person = createModel({
  address: Types.model.of(Address)
})

collection

Collections can also be embedded in models:

import { Types, createModel } from 'tydel';

const Author = createModel({
  books: Types.collection
});

If you want to be more strict about which Collection class can be embedded, use collection.of:

const Book = createModel({
  title: Types.string
});

const Books = createCollection(Book);

const Author = createModel({
  books: Types.collection.of(Books)
});
