Rah*_*itt 5 javascript rollup server svelte
我正在尝试部署我的 svelte 项目,但在 livereload 插件之外激活捆绑 javascript 时遇到问题。当我运行 rollup -c -w 时,代码显示正常,但使用其他服务器为应用程序提供服务不会激活 javacsript。它至少应该在 console.log 中记录一些内容,并希望添加 html,但它只显示一个空白页面。
rollup.config.js
import svelte from "rollup-plugin-svelte";
import resolve from "@rollup/plugin-node-resolve";
import commonjs from "@rollup/plugin-commonjs";
import livereload from "rollup-plugin-livereload";
import replace from "@rollup/plugin-replace";
import { terser } from "rollup-plugin-terser";
import postcss from "rollup-plugin-postcss";
import babel from "rollup-plugin-babel";
export default {
input: "src/main.js",
output: {
sourcemap: true,
format: "iife",
name: "app",
file: "public/build/bundle.js"
},
plugins: [
babel({
exclude: "node_modules/**"
}),
svelte({
// enable run-time checks when not in production
dev: !production,
// we'll extract any component CSS out into
// a separate file - better for performance
css: css => {
css.write("bundle.css");
}
}),
postcss(),
// If you have external dependencies installed from
// npm, you'll most likely need these plugins. In
// some cases you'll need additional configuration -
// consult the documentation for details:
// https://github.com/rollup/plugins/tree/master/packages/commonjs
resolve({
browser: true,
dedupe: ["svelte"]
}),
commonjs(),
// In dev mode, call `npm run start` once
// the bundle has been generated
!production && serve(),
// Watch the `public` directory and refresh the
// browser on changes when not in production
!production && livereload("public"),
// If we're building for production (npm run build
// instead of npm run dev), minify
production && terser(),
// for absolut imports
// i.e., instead of
// import Component from "../../../../components/Component.svelte";
// we will be able to say
// import Component from "components/Component.svelte";

watch: {
clearScreen: false

rollup -c 将输出bundle.js。我的index.html如下

这是运行 livereload 时 chrome 控制台的样子的图片。汇总-c -w
这是 chrome 控制台在生产或其他服务器中的样子的图片。rollup -c 并仅提供静态内容。我不确定 livereload 是否对 javascript 做了一些特殊的事情,但在我的其他服务器中,我确保提供公共文件夹。我可以在控制台中查看bundle.js。
好吧,我已经解决了这个问题,但我不明白为什么。我将分享我的发现,并在我了解更多后返回更新。首先,我在生产中遇到问题的原因是我试图访问 {product_url}/index.html。无论出于何种原因,即使 html 可以检索所有必要的 javascript 和 css,我也无法通过调用 index.html 来简化前端。但是,一旦我修复了路线 {product_url}/ 的静态引用,它就可以正确地为我的应用程序提供水合。在本地主机中也可以看到相同的影响。localhost:5000/ 正确水合,但 localhost:5000/index.html 不会水合。
