pg and sequelize as lambda layer

avoids deploying

du -sh node_modules
15M	node_modules

with pg and sequelize as dependencies

build your own

1. yarn install
2. zip layer:

   mkdir nodejs && \
   cp -r node_modules nodejs/node_modules && \
   zip -r layer.zip nodejs && \
   rm -rf nodejs

3. customize prefixed cli variable assignments, then publish:

   APP_NAME=lambda-layer RUNTIME=nodejs REGION=us-east-1; \
   aws lambda publish-layer-version \
         --layer-name=$APP_NAME-$RUNTIME-deps \
         --description="$APP_NAME dependencies" \
         --zip-file=fileb://$(PWD)/layer.zip \
         --region=$REGION \
         --query 'LayerVersionArn' \
         --output=text

4. assign aws account number, then add permission:

   APP_NAME=lambda-layer RUNTIME=nodejs REGION=us-east-1 AWS_ACCOUNT_NUMBER=123456789012; \
   aws lambda add-layer-version-permission \
       --layer-name=$APP_NAME-$RUNTIME-deps \
       --statement-id GetLayerPermission \
       --action lambda:GetLayerVersion  \
       --principal $AWS_ACCOUNT_NUMBER \
       --version-number 1 \
       --region=$REGION

finally, reference LayerVersionArn from publish output in cloudformation or console
