Serverless get list of local functions

2.9k Views Asked by At

Scenario

I'm writing unit tests for local Lambda Output. Instead of manually putting in the names of all the different lambda functions I'm wanting to dynamically generate the list.

sls deploy list functions

Will return the list of functions that are deployed to aws, but not the ones that are in the local serverless environment

Question

How do I get a list of functions that are local?

The help menu is useful for how to run a local function, but not to assemble a local functions list.

$ sls --help
