Preferred way of using Bootstrap in Webpack
I am not sure if this is the best way, but following work for me well with vue.js webapp. You can see the working code here.
I have included files required by bootstrap in index.html like this:
<head> <meta charset="utf-8"> <title>Hey</title> <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, minimal-ui"> <link rel="stylesheet" href="/static/bootstrap.css" type="text/css"> <script src="//cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/tether/1.3.7/js/tether.min.js" integrity="sha384-XTs3FgkjiBgo8qjEjBk0tGmf3wPrWtA6coPfQDfFEY8AnYJwjalXCiosYRBIBZX8" crossorigin="anonymous"></script> <script href="/static/bootstrap.js"></script></head>And this works, you can execute the repo. Why I went this way was I had to customise some config in bootstrap so I had to change the variables file and build the code of bootstrap which outputted me bootstrap.js and bootstrap.cssfiles, which I am using here.
There is an alternative way suggested here by using the npm package and a webpack customisation.
First install bootstrap in your project:
npm install bootstrap@4.0.0-alpha.5And make sure you can use sass-loader in your components:
npm install sass-loader node-sass --save-devnow go to your webpack config file and add a sassLoader object with the following:
sassLoader: { includePaths: [ path.resolve(projectRoot, 'node_modules/bootstrap/scss/'), ],},projectRoot should just point to where you can navigate to node_packages from, in my case this is: path.resolve(__dirname, '../')
Now you can use bootstrap directly in your .vue files and webpack will compile it for you when you add the following:
<style lang="scss"> @import "bootstrap";</style>
I highly recommend using bootstrap-loader. You add a config file (.bootstraprc in your root folder) where you can exclude the bootstrap elements you don't want and tell where your variables.scss and bootstrap.overrides.scss are. Define you SCSS variables, do your overrides, add your webpack entry and get on with your life.
I use webpack to build bootstrap directly from .less and .scss files. This allows customizing bootstrap by overriding the source in .less/.scss and still get all the benefits of webpack.
Your code is missing an entry point for any .css/.less/.scss files. You need to include an entry point for the compiled css files. For this entry point, I declare an array with const and then include paths inside the array to the source files I want webpack to compile.
Currently, I'm using bootstrap 3 with a base custom template and also a 2nd custom theme. The base template uses bootstrap .less file styling and it has specific source overrides written in .less files.
The 2nd custom theme uses .sass file styling and has similar overrides to bootstrap's base written in .scss files. So, I need to try to optimize all this styling for production (currently coming in about 400kb but that's a little heavy because we choose to avoid CDN's due to targeting use in China).
Below is a reference webpack.config.js which works to build from .less/.scss/.css files, and also does a few other things like build typescript modules and uses Babel for converting es6/typescript to browser compatible javascript. The output ultimately ends up in my /static/dist folder.
