initializing store w/ this.$state not updating state on store instance

[tomschulze]

hi,

not sure if i am just using bad practice code, so i opened a discussion instead of an issue.

I was using pinia 2.0.0-beta.2 before updating to rc9. with the update my store initialization pattern broke; actually it breaks from 2.0.0-beta.4 on.

i created two sandboxes with the same code but different pinia versions. beta2 works, rc9 doesn't. please checkout the stores/cart.js file and the init() function there.

basically i use this.$state = data to replace the whole store, however the getters return the default empty store state.

what am I doing wrong?

codesandbox rc9

This seems like a regression to me, the code comment for $state does say:

State of the Store. Setting it will replace the whole state.

That evidently worked before but seems to break reactivity now if you do assign it.
My suggestion would be to create an issue for this.

However as a quick fix, you can instead use $patch which achieves the same result without breaking reactivity:

// change the following
this.$state = data
// to this
this.$patch(data)

thanks for the workaround! i'll create an issue then.
