A nodejs lambda that exposes a function url that can be used as a proxy to send emails using AWS SES. Before sending any emails using SES you need to follow the Getting started guide.
Clone the repo
git clone https://github.com/martinhjartmyr/aws-ses-node-lambda-proxy.git && cd aws-ses-node-lambda-proxyInstall deps
yarn installBuild the lambda
yarn buildCreate an AWS IAM Role and attach required policys
aws iam create-role --role-name ses-proxy --assume-role-policy-document file://trust-policy.json && aws iam attach-role-policy --policy-arn arn:aws:iam::aws:policy/service-role/AWSLambdaBasicExecutionRole --role-name ses-proxy && aws iam attach-role-policy --policy-arn arn:aws:iam::aws:policy/AmazonSESFullAccess --role-name ses-proxyCopy the Arn from the output and use it in the next step.
arn:aws:iam::123456789:role/ses-proxy
Create the lambda function with a 10 second timeout, 256mb of memory and use the role arn from the output above
aws lambda create-function --function-name ses-proxy --runtime "nodejs16.x" --timeout 10 --memory-size 256 --zip-file "fileb://dist/index.zip" --handler index.handler --role [!!! CHANGE ME ROLE FROM ABOVE OUTPUT !!!]Set the required environment API_KEY secret
aws lambda update-function-configuration --function-name ses-proxy --environment "Variables={API_KEY=[!!! CHANGE ME!!!],DEBUG=false}"Create a function URL. The output will display the generated URL that will be publicly accessible.
aws lambda create-function-url-config --function-name ses-proxy --auth-type NONEGrant access to call the lambda function from the url
aws lambda add-permission --function-name ses-proxy --statement-id AuthNone --action lambda:InvokeFunctionUrl --principal "*" --function-url-auth-type NONECongrats, you should now be able to use the proxy to send emails. Give it a try using the curl example below.
curl --location --request POST 'https://[!!! CHANGE_ME !!!].lambda-url.eu-north-1.on.aws/' \
--header 'x-api-key: [!!! CHANGE ME_!!!]' \
--header 'Content-Type: application/json' \
--data-raw '{
