Build your application

sam build

The output of SAM CLI build command contains the function code & its dependencies. This results in a deployment package size is larger than necessary. Regarding the package size, webpack can be used to reduce bundle size significantly.

Deploy your application to the AWS Cloud

# For interactive mode
sam deploy --guided
# For subsequent deployments
sam deploy

The deployment package will be generated and uploaded to the specified S3 bucket.

Test your deployment

curl --location 'YOUR_API_GATEWAY_ENDPOINT' \
--header 'Accept: application/pdf' \
--header 'Content-Type: application/json' \
--data '{
    "content": "<h1>Hello world</h1>"
}'
