试图在Nuxt和typescript中创建一个项目。然而,文档很差,我遇到了很多问题。不知何故能够解决大部分问题,但堆积在商店的问题上。根据Nuxt文档,store目录中的每个文件都转换为一个模块。
为了更好地组织我的项目,我决定在商店文件夹中添加一个子文件夹。但是,在此更改之后,我的组件在调用Mutation,Action和从商店/模块获取值时遇到问题。
当我在Vue选项卡(Vuex)中检查开发者控制台时,我可以看到我的State和getters在模块之前有子文件夹名称。
如果我决定将每个新模块/商店放在商店文件夹中,一切都工作得很好。
我在我的模块中使用vuex-module-decorators
包,因为在我看来它提高了代码的可读性并简化了过程。
我得到的错误是:
[vuex] unknown action type: applicationStage/initializeArticles
[vuex] unknown mutation type: applicationStage/addArticle
所以问题是:
我的商店文件夹结构
-store
--index.ts
--progress
---applicationStage.ts
./store/progress/application stage.同时
import {
Module,
Action,
VuexModule,
Mutation,
MutationAction

body: string;

};
}
const articles = [
{
title: "Hello World!",
body: "This is a sample article.",
published: true,

},

}
}

我创建了一个沙箱,我的问题可以复制https://codesandbox.io/s/723xyzl60j
你应该使用const applicationStage = namespace("progress/applicationStage/");
而不是getModule(...)
。当stateFactory
是true
时,module
被“自动加载”。您可能还需要直接在decorator
中注入商店。嗯,当你使用stateFactory
时,namespaced
选项是无用的,因为它将被命名为由于stateFactory
是true
。
