Recently I was rewriting the email client using Vue and encountered an error when using Vuex to process data.

Could not find a declaration file for module 'vuex'.

Vuex does not have @types/vuex, so it can only be solved by adding d.ts manually.

Add vuex.d.ts in the project directory and add the following content:

declare module "vuex" {
   export * from "vuex/types/index.d.ts";
   export * from "vuex/types/helpers.d.ts";
   export * from "vuex/types/logger.d.ts";
   export * from "vuex/types/vue.d.ts";
}
