Description:

I'm not sure where to log this issue (I've logged it before for reference: nodejs/nan#883).

Trying to compile a simple SASS project (that uses this: https://github.com/carbon-design-system/ibm-security) fails (after maybe 10 minutes) with this error:

Assertion failed: (size <= imp::kMaxLength && "too large buffer"), function CopyBuffer, file ../node_modules/nan/nan.h, line 904.

I can consistently reproduce this on my machine by doing the following:

# create a standard react app
npx create-react-app my-ibm-security-react-app
cd my-ibm-security-react-app

# add node-sass and @carbon/ibm-security
yarn add node-sass @carbon/ibm-security @carbon/type

# create a .env file to add your node_modules to the SASS loader
# as described here: https://create-react-app.dev/docs/adding-a-sass-stylesheet/
# without this, imports won't work.
echo "SASS_PATH=node_modules" > .env

# rename the .css files to .scss
mv src/index.css src/index.scss
mv src/App.css src/App.scss

# edit the .js files to import .scss instead of .css
sed -i '' 's/index.css/index.scss/' src/index.js
sed -i '' 's/App.css/App.scss/' src/App.js

# add the @carbon/ibm-security scss styles to index.scss
echo '@import "@carbon/ibm-security/scss/index";' >> src/index.scss

# then start
npm run start

If I don't import the SCSS components of the ibm-security package @carbon/ibm-security/scss/index and instead just import their CSS components like this: @carbon/ibm-security/css/index.min.css the compile works fine, so I'm assuming that this is related to some buffer/memory size related to how the scss is being compiled?

How large are the sass files question?

[alaaalii]

node_modules/@carbon/ibm-security/ is 21 MB, but it has a few dependencies in the same @carbon directory, @carbon is 57 MB. Here's the breakdown of all other carbon related dependencies:

$ du -h -d1 node_modules | grep carbon
 10M    node_modules/carbon-components
 42M    node_modules/carbon-components-react
 57M    node_modules/@carbon
1.5M    node_modules/carbon-icons

Those are the sizes of the whole folders (which include .js files). But if you just wanted to know how big the total size of just .scss files in all of the above folders, then it's 5.6 MB:

$ find node_modules/*carbon* -name "*.scss" | xargs du -h -c | tail -1
5.6M    total
