Sass (Sass) Question

How to get brunch & sass-brunch to compile/include bootstrap.scss?

I'm new to brunch, but in trying to set it up with sass-brunch and bootstrap-4.0.0-alpha.2 as npm-installed modules, I'm unable to get it to include bootstrap.scss. Any ideas on what I'm doing wrong?

Here's a small example project.

My package.json:

"name": "simple-brunch",
"version": "0.1.0",
"private": true,
"devDependencies": {
"bootstrap": "^4.0.0-alpha.2",
"brunch": "^2.5.3",
"javascript-brunch": "^2.0.0",
"sass-brunch": "^2.0.0"

My brunch-config.js:

module.exports = {
config: {
files: {
javascripts: {
joinTo: {
'vendor.js': /^(?!app)/,
'app.js': /^app/
stylesheets: {
joinTo: {
'vendor.css': /^(?!app)/,
'app.css': /^app/

npm: {
styles: {
bootstrap: ['scss/bootstrap.scss']

The output from
brunch build -d
is below.
is successfully being used to process
- there's a
line that shows it. However, though a few lines near the top seem to indicate that it's found and compiled bootstrap's
, and a
line near the bottom appears to show that it's concatenated it to
, that file is empty except for the comment that points at
), and that map only contains

Things I tried that didn't work:

  • Adding a
    plugins.sass.options.includePaths: ['node_modules/bootstrap/scss']
    setting to brunch-config.js; no change in output.

  • Adding a
    paths.watched: ['app', 'test', 'vendor', 'node_modules/bootstrap/scss']
    setting to brunch-config.js -- it now seems to find & watch all the files in that directory, but still isn't sending bootstrap.scss through the brunch pipeline to where sass-brunch can have a crack at it.

Here's the output:

npm.styles should only be used to add compiled CSS from node_modules. In this case, if you didn't want to customize bootstrap, you could use

npm: {
  styles: {
    bootstrap: ['dist/css/bootstrap.css']

Or, to use its sass version (to customize it and so on), you would need to:

  1. plugins.sass.options.includePaths = ['node_modules/bootstrap/scss'], as you tried. This simply adds bootstrap to sass' load path
  2. actually @import 'bootstrap' in your SASS file. Otherwise, how would SASS know if it should include that one or not, and where to include?

Note that in this case you will have one big css file as the output (app.css)
