Cannot specify a payload on a getter

[kpturner]

I tried vuex-typescript but got frustrated by the fact that I could not define a payload parameter on a getter and have it recognised by the proxied function, so I switched to this library in the hope that it was fixed but it still gives me a typescript error. This seems to work fine for actions and mutations, but not getters.

Example (assumes a module called config)

    getters: {
        getConfig(state: IConfigModuleState, path: string): any {
            return state[path];
        }
    }

^^^^ takes a path parameter

I then define

const { read } = getStoreAccessors<IConfigModuleState, IRootState>('config');
export const readConfig = read(config.getters.getConfig)

But if I try to reference that anywhere like this:

readConfig(this.$store, 'foo')

I get a typescript error: Expected 1 arguments but got 2

As I say, it seems fine for actions and mutations

What have I done wrong?

Had the exact same problem but finally found that it returns the getter itself. So you can do
readConfig(this.$store)('foo')

Getters do not accept payloads, they're just Computed Props for the Store.

• https://vuex.vuejs.org/guide/getters.html
• https://vuex.vuejs.org/guide/modules.html

You can return a function from a Getter to allow some sort of querying, but keep in mind that only that created function itself is cached as a value, not the calculations that that function itself does.
