Fn - Workflow

Intro. Quick recommendations and tips for various processes.

Development Workflow

Write your functions
Use serverless deploy only when you've made changes to serverless.yml and in CI/CD systems.
Use serverless deploy -f myFunction to rapidly deploy changes when you are working on a specific Fn Function.
Use serverless invoke -f myFunction -l to test your Fn Functions.
Write tests to run locally.

Larger Projects

Break your application/project into multiple Serverless Services.
Model your Serverless Services around Data Models or Workflows.
Keep the Functions and Resources in your Serverless Services to a minimum.

Cheat Sheet

A handy list of commands to use when developing with the Serverless Framework.

Creates a new Service

serverless create -p [SERVICE NAME] -t fn-nodejs

serverless create -p [SERVICE NAME] -t fn-go

Deploy All

Use this when you have made changes to your Functions, Events or Resources in serverless.yml or you simply want to deploy all changes within your Service at the same time.

serverless deploy

Deploy Function

Use this to quickly overwrite your Fn Functions, allowing you to develop faster.

serverless deploy -f [FUNCTION NAME]

Invoke Function

Invokes an Fn Function and returns logs.

serverless invoke -f [FUNCTION NAME] -l

Streaming Logs
