MobX Quick Start Guide

The API layer

This is the consumer facing, outermost layer of MobX and builds on the foundations mentioned thus far. The prominent APIs that stand out in this layer include the ones seen throughout this book: observable(), observable.box(), computed(), extendObservable(), action(), reaction(), autorun(), when(), and others. Of course, we also have the decorators, such as observable.ref, observable.deep, observable.shallow, action.bound, computed.struct, and so on.

The core data structures such as ObservableObject, ObservableArray, and ObservableMap rely on the ObservableValue to store all of their values.

For an ObservableObject...:

• A key-value pair has its value backed by an ObservableValue.
• Every computed property, as expected, is backed ...
