This AWS lambda layer contains a pre-built sharp npm library. It is optimized to reduce the total payload size.

A pre-built layer zip file is available at dist/sharp-layer.zip.

• Docker

1. Clone the repo:

   git clone git@github.com:Umkus/lambda-layer-sharp.git
   cd lambda-layer-sharp/

2. Run Docker if it's not already.

3. Build

   npm run build

   This will install and then build within a lambci/lambda docker image. Then the compiled binaries will be copied to dist and zip archived. Finally it will execute a require. If the result output is function methods, then the build succeeded.

4. Import created layer into your AWS account:

   aws lambda publish-layer-version \
      --layer-name sharp \
      --description "Sharp layer for image resizer" \
      --license-info "Apache License 2.0" \
      --zip-file fileb://dist/sharp-layer.zip \
