This plugin allows you to capture Zustand mutations/state and inspect them later on while replaying session recordings. This is very
useful for understanding and fixing issues.
Installation
{`npm i @openreplay/tracker-zustand --save`}
Usage
Initialize the @openreplay/tracker package as usual and load the plugin into it. Then put the generated plugin into your plugins
field of your store.
{`import create from "zustand";
import Tracker from '@openreplay/tracker';
import trackerZustand, { StateLogger } from '@openreplay/tracker-zustand';
const tracker = new Tracker({
projectKey: ${projectKey},
});
// as per https://docs.pmnd.rs/zustand/guides/typescript#middleware-that-doesn't-change-the-store-type
// cast type to new one
// but this seems to not be required and everything is working as is
const zustandPlugin = tracker.use(trackerZustand()) as unknown as StateLogger
const useBearStore = create(
zustandPlugin((set: any) => ({
bears: 0,
increasePopulation: () => set((state: any) => ({ bears: state.bears + 1 })),
removeAllBears: () => set({ bears: 0 }),
}),
// store name is optional
// and is randomly generated if undefined
'bear_store'
)
)
`}
}
