In this course, we will create a complete React Application with the state management handled by MobX State Tree, a state container system that is built on MobX, a functional reactive state library.

MobX State Tree will give your application a solid structure and foundation for large-scale applications and for small applications that are expected to scale rapidly. In comparison to Redux, MobX State Tree outstands it in performance with much less boilerplate. MobX is one of the most popular Redux alternatives and it's used by companies all over the world, including Netflix, Grow, IBM, DAZN, Baidu, and more.

During this course, you'll learn:

* Types in MobX State Tree.
* How to create the architecture of a centralized store.
* How to mutate the state via actions that could be asynchronous or not, depending on if we need to perform network requests to persist data into a database via GraphQL.
* Understanding snapshots and how we can benefit from them to time-travel if a network request fails.
* Understanding how MobX State Tree makes use of observable properties and observers.
* Leveraging re-renders in your React Application to MobX observers for better performance optimizations.

By the end of this course, you will have the knowledge and skills that it takes to build a real-world, production-level React Application with a State Management with top-notch performance that can scale with ease.

In this course, we'll show you how to build a React App with MobX State Tree.

# Application overview

Welcome to the first lesson of this course about **MobX State Tree** (MST for short).

In this course, we will uncover the secrets behind this wonderful and strongly typed state management library that will help you build cutting-edge applications with the latest and best possible technology out there.

## What are we building?

We're going to build an Instagram-like application powered by MobX State Tree as the state management library. You will get to see with your own eyes how reliable, powerful and flexible, MST can be when developing applications that could potentially scale in complexity without any tradeoffs. We will delegate component rendering to the MST observers, which will smartly keep track of state changes in your stores and only update the components that are bounded to it in the user interface.

## Backend

The backend of this application will be powered by an [Apollo GraphQL Server](https://www.apollographql.com/), but we are not going to get into much detail about this because it's not what this course is about. Surely, we will take a quick look at the backend explaining the type definitions that we have because they will match with our MST store definitions. This is one of the best things about MST; we can retrieve structured application data and simply apply it to the store and it will automatically populate the store with the same structure that our GraphQL backend returns.
