    DatX is an opinionated data store for use with the MobX state management library. It features support for simple observable property definition, references to other models and first-class TypeScript support.

    datx-jsonapi is a datx mixin that adds JSON API support.

    Basic usage

    import { Collection, Model, prop } from 'datx';
    import { jsonapi } from 'datx-jsonapi';
    import { computed } from 'mobx';
    class Person extends jsonapi(Model) {
      public static type = 'person'; // Unique name of the model class
      @prop name: string; // A normal observable property without a default value
      @prop surname: string;
      @prop.toOne(Person) spouse?: Person; // A reference to a Person model
      @computed get fullName() { // Standard MobX computed props
        return `${this.name} ${this.surname}`;
    class AppData extends jsonapi(Collection) {
      public static types = [Person]; // A list of models available in the collection
    const store = new AppData();
    const john = store.add(new Person({name: 'John', surname: 'Smith'})); // Add a model instance to the store
    const jane = store.add({name: 'Jane', surname: 'Smith', spouse: john}, Person); // Add a model to the store
    await john.save(); // POST to the server
    const people = await store.fetchAll(Person); // Get all people from the server

    Getting started

    Note: datx-jsonapi has a peer dependency to mobx@^4.2.0 or mobx@^5.5.0, so don't forget to install the latest MobX version:

    npm install --save datx-jsonapi mobx


    The lib makes use of the following features that are not yet available everywhere. Based on your browser support, you might want to polyfill them:

    How to add the polyfills. Note: Fetch API is not included in the polyfills mentioned in the Troubleshooting page. Instead, you need to add it as a separate library. If you don't have any special requirements (like server-side rendering), you can use the window.fetch polyfill.
