MobX State Tree with TypeScript example
Usually splitting your app state into pages feels natural but sometimes you'll want to have global state for your app. This is an example on how you can use mobx that also works with our universal rendering approach.
In this example we are going to display a digital clock that updates every second. The first render is happening in the server and the date will be 00:00:00, then the browser will take over and it will start updating the date.
To illustrate SSG and SSR, go to /ssg and /ssr, those pages are using Next.js data fetching methods to get the date in the server and return it as props to the page, and then the browser will hydrate the store and continue updating the date.
The trick here for supporting universal mobx is to separate the cases for the client and the server. When we are on the server we want to create a new store every time, otherwise different users data will be mixed up. If we are in the client we want to use always the same store. That's what we accomplish on store.js
The clock, under components/Clock.js, has access to the state using the inject and observer functions from mobx-react. In this case Clock is a direct child from the page but it could be deep down the render tree.
