Recently AWS introduced Layers which enables sharing common code between functions and working with large dependencies (such as headless chrome) much easier.
This project example returns a screenshot of page requested via ?address= query parameter.
It is very important to tell NPM to skip installing chromium from puppeteer package. To do so, installing dependencies should be done using this command:
PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=1 npm installor
PUPPETEER_SKIP_CHROMIUM_DOWNLOAD=1 yarnWithout this, your function size would be more than 200MB which is way too much.
After that, you can simply deploy your funciton.
sls deploy
curl <DEPLOYED_ENDPOINT>?address=https://google.comor apply this ARN to your function directly: arn:aws:lambda:us-east-1:085108115628:layer:chrome:6
