node.js - React + react-router `require.ensure 按需加载 服务端渲染出错`

Question

我尝试使用require.ensure这个去做实现了按需加载的效果，但是因为我这边有做服务端渲染，所以现在是前端和服务端公用了一个路由控制器：

const routes = {
    component: Shell(Init),
    childRoutes: [
        {
            path: 'login',
            getComponent: (nextState, cb) => {
                require.ensure([], (require) => {
                    cb(null, require('../containers/login'))
                })
            }
        }
    ]
};

但是在服务端执行却报错了：

TypeError: require.ensure is not a function
    at Object.getComponent (D:/luoo/nodejs/app/routes/routes.jsx:49:25)
    at getComponentsForRoute (D:\luoo\nodejs\node_modules\react-router\lib\getComponents.js:29:16)

    at runEnterHooks (D:\luoo\nodejs\node_modules\react-router\lib\TransitionUtils.js:93:10)

这个有哪个方案可以解决呢?

Answer 1

When the webpack target is node, require is the native node.js require, and there is no require.ensure method.

You can write a shim for the server environment
