Package Exports

serverless-plugin-utils

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (serverless-plugin-utils) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Utility Usage

Function	Description
fn::lower	Converts a string to its lowercase representation

fn::ternary	Performs equality check and returns a defined result
fn::join	Joins a collection of values with a given delimiter
fn::split	Splits a string value on a given delimiter

Caveats

All operations are done after yaml has been processed. This mean certain operations cannot be done in-line.

Example:

something:
  fn::join:
    delimiter: '-'
    values:
      - one
      - two

injected: ${opt:stage}${self:custom.something}

// Serverless Error ---------------------------------------
// Trying to populate non string value into a string for variable ${self:custom.something}. Please make sure the value of the property is a string.

To work around this fully use the utils option. The above can be reworked as the following.

injected:
  fn::join:
    delimiter: '-'
    values:
      - ${opt:stage}one
      - two
