Configuring MobX in the Funbook app

As promised by the MobX authors, the boilerplate for this library is minimal. We will have to add three dependencies and a couple of files for everything to work correctly. Let’s start by adding the necessary dependencies by running the following command in the terminal:

npm install mobx mobx-state-tree –save

This command will install both MobX and MobX-State-Tree. MobX is unopinionated about the UI library we want to use it with. This means that when we decide to use a specific UI library, we will have to find a way to get it to cooperate with MobX. It so happens that we have chosen React Native as our UI library, so we need to add an additional dependency that will make MobX cooperate smoothly with React. Let’s run the following command:

npm install mobx-react-lite –save

Now that we have our dependencies, let’s run the following command:

expo start

It’s a good idea to check frequently...
