A tiny example about how to write a Cycle.js app that runs inside a AWS Lambda function.
The idea is really simple: Use a driver to input Lambda event and context for the main function as a source, and use the sink to send back the result.
All the logic/behavior (and other side-effects like querying a RDS database or making an HTTP call) is handled inside main function with the help of other drivers. Note that the Lambda function must have the correct permissions on its role to execute such tasks.
Emulates a Lambda handler invocation.
If you want to provide a sample test event, configure it inside functions/<function name>/config.json.
Deploys a functions as per functions/<function name>/config.json configurations on the target environment.
You must provide three environment variables (could be in a .env file): REGION, AWS_ACCESS_KEY and AWS_SECRET_ACCESS_KEY with permissions to put objects on S3 and update function code on Lambda.
Emulates a Lambda handler invocation. It does not provide a context object for now.
Deploys a function to Lambda.
Used by .scripts/deploy.js to create a package with function code and node_modules dependencies.
Used to link lib/ code inside the function's folder, allowing emulation and packaging.
