javascript - 使用 CDN 时如何调用 react logger 函数

问题描述

我正在创建文件来学习自己的反应。为了简化我使用 cdn 的事情，直到现在一切都很顺利。我不知道如何将 redux-logger 中间件提供给我的 Redux.applymiddleware fn。

我应该用什么替换 /* 记录器 */ 字符串？

        const store = Redux.createStore( reducer/*, myMiddleware*/ );

        store.dispatch({ type: 'FOO'});

        const currentState = store.getState();

        console.log(currentState)

解决方案

如果您检查他们的 GitHub 存储库中redux-logger的UMD捆绑器配置： https ://github.com/LogRocket/redux-logger/blob/master/rollup.config.js#L33 - 您会看到他们将UMD 捆绑包的模块为reduxLogger. 所以你应该按如下方式访问它：

const logger = window.reduxLogger.logger
