我目前正在创建一个导出单个ES6模块的bower软件包。
在为我的包构建dist时,我使用汇总将所有内部模块移动到一个模块中,只导出一个模块。
Gulp任务:
// Bundle ES6 modules into a single file
gulp.task('bundle', function(){
return gulp.src('./src/GuacaMarkdownEditor.js', {read: false})
.pipe(rollup({
// any option supported by rollup can be set here, including sourceMap
// https://github.com/rollup/rollup/wiki/JavaScript-API
format: 'es6',
sourceMap: true
}))
.pipe(sourcemaps.write(".")) // this only works if the sourceMap option is true
.pipe(gulp.dest('./dist'));
});
这一切都运行正常,但我从其他bower软件包中导入一些依赖项,我不想与我的模块捆绑(jQuery,font-awesome)。
我的问题是:如何保持捆绑我的代码并保留bower软件包的ES6导入语句 - 但是没有汇总将外部代码捆绑到我的软件包中?
示例:
"use strict";
import $ from 'jquery'; // dont bundle this!
import GuacaAirPopUp from './GuacaAirPopUp'; // bundle this!
export
default class GuacaMarkdownEditor {
...
}

您可以使用此汇总插件rollup-plugin-includepaths。
它允许您按名称导入模块,并且应该从捆绑包中排除定义模块。我在rollup.config.js
中使用了它:
import babel from 'rollup-plugin-babel';
import includePaths from 'rollup-plugin-includepaths';
var includePathOptions = {
paths: ['es6'],
include: {
'd3': './global/js/' + 'base/d3.min' // include library in es6 modules
},
external: ['d3'] // but don't bundle them into bundle.js
};
export default {
entry: './es6/entry.js',
plugins: [
includePaths(includePathOptions),
babel()
],
format: 'amd',
dest: 'build/bundle.js',
sourceMap: true
};
在es6模块中:
// not using relative path since it is handled by the plugin
import d3 from 'd3';
import other from 'otherModules';
//...

似乎汇总将检测命名导入(而不是相对路径),作为外部依赖项。
捆绑此模块时:
import GuacaAirPopUp from './GuacaAirPopUp';
import ControlHandlerService from './ControlHandlerService';
import DefaultHandlerConfig from './DefaultHandlerConfig';
import toMarkdown from 'to-markdown';
import $ from 'jquery';
捆绑者给出了这些消息:
Treating 'to-markdown' as external dependency
Treating 'jquery' as external dependency
捆绑使用此模块的应用程序时,使用browserify正确导入了jquery。

安特尔已经回答了,但如果您想在下面排除自己制造的模块,我相信这是一个明确的解释。
https://github.com/rollup/rollup/wiki/JavaScript-API#external
应保留在软件包外部的模块的ID列表
// main.js
import myMod from './my-module'; // <-- this module you don't wanna import
// build.js <--- gulp file
import * as path from 'path';
//...more of you gulp file code
rollup.rollup({
entry: 'app.js',
external: [
'./my-module', // <--- node module to be excluded from the bundle
path.resolve( './src/special-file.js' ) // <--- file you made to be excluded from the bundle
]
}).then(...)
//...more of you gulp file code
// Bundle ES6 modules into a single file
gulp.task('bundle', function(){
return gulp.src('./src/GuacaMarkdownEditor.js', {read: false})
.pipe(rollup({
// any option supported by rollup can be set here, including sourceMap
// https://github.com/rollup/rollup/wiki/JavaScript-API
format: 'es6',
sourceMap: true
}))
.pipe(sourcemaps.write(".")) // this only works if the sourceMap option is true
.pipe(gulp.dest('./dist'));
});
