How do I configure webpack to run bootstrap and sass?
提问by MindfulBell
I am not great at webpack. I have not really 'learned it', I have a template/boilerplate I pull from a repo I made that gives me an environment to build in React. I am struggling to add bootstrap functionality to my projects because I am not great with webpack and understanding how loaders etc. work. Can someone give me a hand? And maybe a simple explanation about webpack loaders? (It is on my list to learn it, but just not a priority).
我不太擅长 webpack。我还没有真正“学会”，我有一个模板/样板，我从我制作的回购中提取，它为我提供了在 React 中构建的环境。我正在努力为我的项目添加引导程序功能，因为我对 webpack 并不擅长，也不了解加载程序等的工作方式。有人可以帮我吗？也许对 webpack loader 做一个简单的解释？（它在我的学习清单上，但不是优先事项）。
I get strange errors like:
我收到奇怪的错误，例如：
ERROR in ./~/bootstrap-sass/assets/fonts/bootstrap/glyphicons-halflings-regular.woff2
./~/bootstrap-sass/assets/fonts/bootstrap/glyphicons-halflings-regular.woff2 中的错误
Here is my webpack.config.js
这是我的 webpack.config.js
var webpack = require('webpack');
var path = require('path');
var BUILD_DIR = path.resolve(__dirname, 'src/client/public');
var APP_DIR = path.resolve(__dirname, 'src/client/app');
var config = {
entry: APP_DIR + '/index.jsx',
output: {
path: BUILD_DIR,
filename: 'bundle.js'
},
module : {
loaders : [
{
test : /\.jsx?/,
include : APP_DIR,
loader : 'babel'
},
{
test: /\.scss$/,
loaders: ["style", "css", "sass"]
}
]
}
};
module.exports = config;

Checkout the example from the sass-loader. Your webpack.config.jsshould look like this:
查看sass-loader 中的示例。你webpack.config.js应该是这样的：
module.exports = {
...
module: {
loaders: [
{
test: /\.woff2?$|\.ttf$|\.eot$|\.svg$/,
loader: "file"
},
{
test: /\.scss$/,
loaders: ["style", "css", "sass"]
}
]
}
};
Since you've added a bunch of loaders, you should make sure that all of them are installed:
由于您添加了一堆加载程序，因此您应该确保安装了所有加载程序：
npm i file-loader style-loader css-loader sass-loader --save-dev
Then you should add your main.scsseither as webpack entry to webpack.config.js...
然后你应该将你的main.scss作为 webpack 条目添加到webpack.config.js...
module.exports = {
...
entry: [
path.resolve(__dirname, '..', 'path', 'to', 'main.scss'),
// add other entries
],
...
... or just require/import it in your main.js:
...或者只是要求/导入它在您的main.js：
require("./path/to/main.scss");
Since bootstrap needs its url()paths configured, you need to set the $icon-font-pathbeforeimporting bootstrap. Your main.scssshould look like this:
由于引导程序需要url()配置其路径，因此您需要$icon-font-path在导入引导程序之前设置。你main.scss应该是这样的：
$icon-font-path: "~bootstrap-sass/assets/fonts/bootstrap/";
@import "~bootstrap-sass/assets/stylesheets/bootstrap";
And if you think @import "~bootstrap-sass/assets/stylesheets/bootstrap";looks ugly, you can also add an alias to your webpack.config.js:
如果你觉得@import "~bootstrap-sass/assets/stylesheets/bootstrap";看起来很丑，你也可以给你的 加一个别名webpack.config.js：
module.exports = {
...
resolve: {
alias: {
"bootstrap-sass$": "bootstrap-sass/assets/stylesheets/bootstrap"
}
},
Then you just need to write:
然后你只需要写：
@import "~bootstrap-sass";

Every extension you import, requireor load any other way must have its own loader.
每个扩展你import，require或者加载任何其他方式必须有自己的装载机。
As of woff2you might have added something like:
至于woff2你可能已经添加了类似的东西：
{
test: /\.woff2$/,
loader: 'url',
query: {
limit: 10240,
name: 'static/[hash].[ext]'
}
}
You might want to check the url-loaderdocumentationabout all the parameters it accepts.
您可能需要查看有关它接受的所有参数的url-loader文档。
You also may match multiple different filename patterns to use with the same loader, eg:
您还可以匹配多个不同的文件名模式以用于同一个加载器，例如：
{
test: /\.(eot|ttf|svg|png|gif|woff2?$/,
loader: 'url',
query: {
limit: 10240,
name: 'static/[hash].[ext]'
}
}
This would load all those extensions.
这将加载所有这些扩展。

It's probably something wrong with ./~/bootstrap-sass/assets/fonts/bootstrap/glyphicons-halflings-regular.woff2path. Bootstrap-sass requires it through the sass file but webpack can't find it.
可能是./~/bootstrap-sass/assets/fonts/bootstrap/glyphicons-halflings-regular.woff2路径有问题。Bootstrap-sass 通过 sass 文件需要它，但 webpack 找不到它。
