Lambda Layer of Npm Package for (ARM64 Arch)

Question

I tried creating a AWS Lambda Layer for npm package Sharp using this Medium Blog but it is not working for AWS Lambda ARM64 Architecture.

I got this error from lambda function:

"Cannot find module '../build/Release/sharp-linux-arm64v8.node'"

I would like to use this AWS Graviton2 processor only.

Can anyone tell me what is missing in this blog post?

Answer 1

Finally fixed it by re-building the npm package.

Step 1: Create a dir and navigate into it.

mkdir layers
cd layers

Step 2: Create another directory nodejs

mkdir nodejs
cd nodejs

Step 3: Install whatever npm pacakges you need

npm install package-name

Step 4: Re-build installed packages for both x64 and arm64 arch

npm rebuild --platform=linux --arch=x64 package_name
npm rebuild --platform=linux --arch=arm64 package_name

Step 5: Move back to layers directory

cd ..

Step 6: Zip the nodejs directory

zip -r name_whatever_you_want.zip nodejs

All Set!! Now we can upload this as a Lambda Layer
