Next.js 和 Webpack 内联 Javascript 或 CSS 资源
Next.js and Webpack inline Javascript or CSS ressources
我有以下用例:我需要使用 React 和 Next.js 生成静态文件。为此,我用以下内容扩展了 next.config.js:
module.exports = {
exportTrailingSlash: true,
exportPathMap: async function () {
const paths = {
'/': { page: '/' }
}
const errorPages = [
{ id: 1, name: '404', lang: 'en' },
{ id: 2, name: '500', lang: 'en' }
]
errorPages.forEach(errorPage => {
paths[`/errorPage/${errorPage.id}`] = {
page: '/errorPage/[id]',
query: { id: errorPage.id }
}
})
return paths
},
}
这完全有效。在 npm export
之后在 out
文件夹中生成文件
另一个用例是这个:
index.html 文件需要在任何地方都能正常工作,而不仅仅是在 out
文件夹中的确切位置。例如,另一个 webapp 查询一个 API,它将 index.html 和 returns 和 html 扫描为该文件中的字符串。这个 html 字符串必须有效,但是 js files/bundles 的引用是相对的(参见 link 和脚本标签):
<!DOCTYPE html>

有没有办法告诉 next 内联包含这个 js 文件?
我尝试了什么:
我正在尝试使用 HtmlWebpackPlugin and HtmlWebpackInlineSourcePlugin 并像这样更新 next.config.js:
const HtmlWebpackPlugin = require('html-webpack-plugin')
const HtmlWebpackInlineSourcePlugin = require('html-webpack-inline-source-plugin')
module.exports = {
exportTrailingSlash: true,
exportPathMap: async function () {
const paths = {
'/': { page: '/' }
}
const errorPages = [
{ id: 1, name: 404', lang: 'en' },
{ id: 2, name: '500', lang: 'en' }
]
errorPages.forEach(errorPage => {
paths[`/errorPage/${errorPage.id}`] = {
page: '/errorPage/[id]',
query: { id: errorPage.id }
}
})
return paths
},
webpack: (config, { buildId, dev, isServer, defaultLoaders, webpack }) => {
// Note: we provide webpack above so you should not `require` it
// Perform customizations to webpack config
// Important: return the modified config
config.plugins.push(new webpack.IgnorePlugin(/\/__tests__\//))
config.plugins.push(
new HtmlWebpackPlugin({
inlineSource: '.(js|css)$' // embed all javascript and css inline
})
)
config.plugins.push(new HtmlWebpackInlineSourcePlugin())
return config
}
}
它不会将资源转换为内联格式并保持 linking 它们。有没有办法通过添加任何其他 webpack 来达到预期的结果,或者是配置错误?
提前致谢!
编辑:这是我的 project.json 依赖部分:
"dependencies": {
"isomorphic-unfetch": "^3.0.0",
"next": "latest",
"react": "^16.12.0",
"react-dom": "^16.12.0",
"html-webpack-inline-source-plugin": "0.0.10",
"html-webpack-plugin": "^3.2.0"
}
我最后做的是使用 StaticDocument
而不是默认的 Document
(在生产环境中)。然后我的 StaticDocument 在导出期间与 CustomHead
一起使用。在那里,所有 link 预加载都被删除。这样,最终导出的 HTML 页面的 <head>
中将不会呈现任何 link 标记。
~/pages/_document.js
import Document, { Main, Head } from 'next/document'
class CustomHead extends Head {
render () {
const res = super.render()
function transform (node) {
// remove all link preloads
if (
node &&
node.type === 'link' &&
node.props &&
node.props.rel === 'preload'
) {
return null
}
if (node && node.props && node.props.children) {
return {
...node,
props: {
...node.props,
children: Array.isArray(node.props.children)
? node.props.children.map(transform)

}
}
}
if (Array.isArray(node)) {

return transform(res)
