This example demonstrates how to compile your JavaScript code with Babel. In order to do so the serverless-babel-plugin is leveraged.
Use Cases
- Using the latest JavaScript language features without waiting for AWS to provide new Node environments.
Setup
Deploy
Serverless: Deprecation Notice: Starting with the next update, we will drop support for Lambda to implicitly create LogGroups. Please remove your log groups and set "provider.cfLogs: true", for CloudFormation to explicitly create them for you. Serverless: Packaging service… Serverless: Babel compilation: tmpBabelDirectory/createResponse.js -> tmpBabelDirectory/createResponse.js tmpBabelDirectory/handler.js -> tmpBabelDirectory/handler.js Serverless: Packaging service with compiled files... Serverless: Uploading CloudFormation file to S3… Serverless: Uploading service .zip file to S3… Serverless: Updating Stack… Serverless: Checking Stack update progress… ............ Serverless: Stack update finished… Service Information service: function-compiled-with-babel stage: dev region: us-east-1 api keys: None endpoints: None functions: function-compiled-with-babel-dev-hello: arn:aws:lambda:us-east-1:377024778620:function:function-compiled-with-babel-dev-hello
Usage
You can now invoke the Lambda directly and even see the resulting log via
serverless invoke --function hello --log
The expected result should be similar to:
{
"statusCode": 200,
"body": {
"message": "Success!"
}
}
