A MobX data store
npm install datx
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.
*
``typescript
import { Collection, Model, prop } from 'datx';
import { computed } from 'mobx';
class Person extends 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 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
`
Note: datx has a peer dependency to mobx@^4.2.0 or mobx@^5.5.0, so don't forget to install the latest MobX version:
`bash`
npm install --save datx mobx
* Installation
* Defining models
* References
* Configuring the collection
* Using the collection
* Persisting data locally
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:
* Symbol.for
* Object.assign
* Array.prototype.find
The library contains two main classes - Model and Collection.
A collection contains models of any kind (they should however be listed in the types property), while a model can be in a single collection (but doesn't need to be in any).
Models also include some useful methods and properties, but if they're in collision with your data/logic, you can use a PureModel class.
Mixins are additional plugins that can enhance the regular models and collections. Available mixins:
* withActions (model) - Adds some helper methods to the model - already included in the Model class, but not in the PureModel classwithMeta
* (model) - Adds some helpful meta data to the model - already included in the Model class, but not in the PureModel classwithPatches
* (model, collection) - Adds patch support to models and collectionsdatx-jsonapi` (model, collection and view) - Adds the JSON API features to the model, collection and view
*
