[英]Webpack v4 creating tiny chunks (by route)
This is some of the code I'm using in my React app.这是我在 React 应用程序中使用的一些代码。 My routes are written using react-router-config which allows me to keep a centralized way so I know where to go always in order to modify or add some.
我的路由是使用react-router-config编写的,它允许我保持集中的方式,所以我总是知道去哪里修改或添加一些。
const routes = [
{
component: Root,
routes: [
{
path: "/",
exact: true,
component: Home
},
{
path: "/child/:id",
component: Child,
routes: [
{
path: "/child/:id/grand-child",
component: GrandChild
}
]
}
]
}
];
Then, let's say the Child component is dinamically imported:然后,假设 Child 组件是动态导入的:
const Child = lazy(() => import('./Child'));
I would expect that the generated chunk includes Child, its imports/dependencies and the GrandChild and its imports/dependencies as well;我希望生成的块包括 Child、它的导入/依赖项和 GrandChild 及其导入/依赖项; but the reality is that the output is a tiny (1kb) file that includes only the lines of this component (Child).
但实际情况是,输出是一个很小的 (1kb) 文件,其中仅包含此组件 (Child) 的行。
How could I make webpack chunk all that matters for /child/:id
route?我怎样才能让 webpack 块对
/child/:id
路由很重要?
Given the lack of solutions out there for such an important feature (I have been searching everywhere for 3 days now), I ended up doing it kind of manually.鉴于如此重要的功能缺乏解决方案(我已经到处搜索了 3 天),我最终还是手动完成了。
Webpack allows to specify the name of the chunk that a dynamic import will generate. Webpack 允许指定动态导入将生成的块的名称。 If you use the same name for all the relevant components involved in a feature (if features are your approach to chunking), then you can do something like this:
如果您对功能中涉及的所有相关组件使用相同的名称(如果功能是您的分块方法),那么您可以执行以下操作:
/* ********************************** ACCOUNT ********************************** */
export const Account = lazy(() => import(/* webpackPrefetch: true, webpackChunkName: "cuenta" */ './pages/Account/Account'));
export const MyConsumption = lazy(() => import(/* webpackPrefetch: true, webpackChunkName: "cuenta" */ './pages/Account/MyConsumption/MyConsumption'));
export const MyAccount = lazy(() => import(/* webpackPrefetch: true, webpackChunkName: "cuenta" */ './pages/Account/MyAccount/MyAccount'));
export const Settings = lazy(() => import(/* webpackPrefetch: true, webpackChunkName: "cuenta" */ './pages/Account/Settings/Settings'));
export const Notifications = lazy(() => import(/* webpackPrefetch: true, webpackChunkName: "cuenta" */ './pages/Account/Notifications/Notifications'));
/* ********************************** OTHER PRODUCTS ********************************** */
export const Sectors = lazy(() => import(/* webpackPrefetch: true, webpackChunkName: "otros-productos" */ './pages/OtherProducts/Sectors/Sectors'));
export const SectorsList = lazy(() => import(/* webpackPrefetch: true, webpackChunkName: "otros-productos" */ './pages/OtherProducts/Sectors/SectorsList/SectorsList'));
export const SectorFile = lazy(() => import(/* webpackPrefetch: true, webpackChunkName: "otros-productos" */ './pages/OtherProducts/Sectors/SectorFile/SectorFile'));
export const SectorRiskReport = lazy(() => import(/* webpackPrefetch: true, webpackChunkName: "otros-productos" */ './pages/OtherProducts/Sectors/SectorRiskReport/SectorRiskReport'));
export const PressMail = lazy(() => import(/* webpackPrefetch: true, webpackChunkName: "otros-productos" */ './pages/OtherProducts/PressMail/PressMail'));
export const ValoraInfo = lazy(() => import(/* webpackPrefetch: true, webpackChunkName: "otros-productos" */ './pages/OtherProducts/Valora/ValoraInfo'));
export const ValoraReport = lazy(() => import(/* webpackPrefetch: true, webpackChunkName: "otros-productos" */ './pages/OtherProducts/Valora/ValoraReport'));
And the result will be chunks like this (notice the 2 chunks above the one in yellow, result of the code you see above):结果将是这样的块(注意黄色块上方的 2 个块,这是您在上面看到的代码的结果):
This is something that is worth sharing and a way to create chunks that make sense.这是值得分享的东西,也是一种创建有意义的块的方法。 My main chunk is way lighter and the vendor one as well, so we can provide a progressive experience and cache the resources that will be used again and again by the user.
我的主要部分更轻,供应商也是如此,因此我们可以提供渐进式体验并缓存用户将一次又一次使用的资源。
I hope I help someone out there.我希望我能帮助那里的人。
