问题描述
我正在按照Vue官方页面提供的示例,尝试使用Vue和Buble汇总编译SFC.但我不断收到此错误:
I am trying to compile SFC with rollup, using Vue and Buble, following the example suplied in the Vue official page. But I keep getting this error:
src/wrapper.js → dist/chat.min.js...
[!] (plugin buble) SyntaxError: Unexpected token (2:0)
src\components\Chat.vue?vue&type=style&index=0&lang.scss (2:0)
1 :
2 : .chat, .chat>*, .chat * {
这是我的rollup.config.js:
This is my rollup.config.js:
import commonjs from '@rollup/plugin-commonjs'; // Convert CommonJS modules to ES6
import vue from 'rollup-plugin-vue'; // Handle .vue SFC files
import buble from '@rollup/plugin-buble'; // Transpile/polyfill with reasonable browser support
export default {
input: 'src/wrapper.js', // Path relative to package.json
output: {
name: 'Chat',
exports: 'named',
},
plugins: [
commonjs(),
vue({
css: true, // Dynamically inject css as a <style> tag
compileTemplate: true, // Explicitly convert template to render function
}),
buble(), // Transpile to ES5
],
};
这是我的wrapper.js:
And this is my wrapper.js:
// Import vue component
import component from "./components/Chat.vue";
// Declare install function executed by Vue.use()
export function install(Vue) {
if (install.installed) return;
install.installed = true;
Vue.component("chat", component);
}
// Create module definition for Vue.use()
const plugin = {
install
};
// Auto-install when vue is found (eg. in browser via <script> tag)
let GlobalVue = null;
if (typeof window !== "undefined") {
GlobalVue = window.Vue;
} else if (typeof global !== "undefined") {
GlobalVue = global.Vue;
}
if (GlobalVue) {
GlobalVue.use(plugin);
}
// To allow use as module (npm/webpack/etc.) export component
export default component;
我尝试从插件中删除气泡,但最终出现错误消息意外令牌(请注意,您需要插件才能导入不是JavaScript的文件)"
I've tried removing buble from the plugins, but I end up with an error saying "Unexpected token (Note that you need plugins to import files that are not JavaScript)"
推荐答案
// rollup.config.js
import fs from 'fs';
import path from 'path';
import VuePlugin from 'rollup-plugin-vue';
import alias from '@rollup/plugin-alias';
import commonjs from '@rollup/plugin-commonjs';
import replace from '@rollup/plugin-replace';
import babel from 'rollup-plugin-babel';
import minimist from 'minimist';
import css from 'rollup-plugin-css-only';
// Get browserslist config and remove ie from es build targets
const esbrowserslist = fs.readFileSync('./.browserslistrc')
.toString()
.split('\n')
.filter((entry) => entry && entry.substring(0, 2) !== 'ie');
const argv = minimist(process.argv.slice(2));
const projectRoot = path.resolve(__dirname, '..');
const baseConfig = {
input: 'src/entry.js',
plugins: {
preVue: [
alias({
resolve: ['.js', '.vue', '.css'],
'vue$': require.resolve('vue/dist/vue.esm-bundler.js'),
entries: {
'@': path.resolve(projectRoot, 'src')
}
}),
],
replace: {
'process.env.NODE_ENV': JSON.stringify('production'),
'process.env.ES_BUILD': JSON.stringify('false'),
},
vue: {
css: false,
template: {
isProduction: true,
},
},
babel: {
exclude: 'node_modules/**',
extensions: ['.js', '.jsx', '.ts', '.tsx', '.vue'],
}
},
};
const external = [
'vue',
];
// Customize configs for individual targets
const buildFormats = [];
if (!argv.format || argv.format === 'es') {
const esConfig = {
...baseConfig,
external,
output: {
file: 'dist/vue3lib.esm.js',
format: 'esm',
exports: 'named',
},
plugins: [
replace({
...baseConfig.plugins.replace,
'process.env.ES_BUILD': JSON.stringify('true'),
}),
...baseConfig.plugins.preVue,
VuePlugin(baseConfig.plugins.vue),
babel({
...baseConfig.plugins.babel,
presets: [
[
'@babel/preset-env',
{
targets: esbrowserslist,
},
],
],
}),
commonjs(),
css()
],
};
buildFormats.push(esConfig);
}
// Export config
export default buildFormats;
希望这会为条目生成esm包
Hope this will generate esm bundle for the entry
