serverless-learning

This is my effort to learn how to use the serverless library in setting up and deploying lambda functions.

Things used

  • Serverless
  • RollupJS (to bundle)
  • Typescript (duh)
  • Lodash (just to experiment with rollup's treeshaking)

Commands to know

  1. To deploy your serverless infrastructure (which is configured by your serverless.yml file): serverless deploy -v
  2. To invoke your function: serverless invoke -f <function_name> -l
  3. To tail your function's logs: serverless logs -f <function_name> -t
  4. To remove your serverlesss infrastructure (based on your serverless.yml: serverless remove
  5. To deploy a single function and not the whole thing: serverless deploy function -f <function_name>

Nice to know

  • AWS Lambda functions can be configured to have triggers. Cloudwatch events are a great way to setup cronjobs with Lambda as you can setup scheduled runs.
  • we can have multiple functions setup and deployed in a single repository with serverless.yml. will just need some extra configurations with rollup as well (possibly split the rollup.config.js into separate files for each function?)
