[SOLVED] Access variables in code source

Serverless Framework
1

Is there a way to access configuration variables (environment, etc.) from the source code?

I read about context.stageVariables but it’s empty for me when I run serverless invoke local -f create --path mocks/create-feedback.json

You can set the env vars on the provider or function level

# Service metadata
service:
  name: basic-example
  displayName: Basic Example
  version: 0.0.1
  description: "Demonstrate Hello World"

# Service provider
provider:
  name: aws
  runtime: nodejs6.10
  environment:
    My_key: ${opt:whateverVariable}

# Functions in service
functions:
  hello:
    handler: handler.hello
    environment:
      My_key_in_this_func_only: ${opt:whateverVariableTwo}

Then in your code you can access the variables on process.env like:

console.log(process.env.My_key)

I used the ${opt:whateverVariable} variable syntax to reference CLI flags but you can use any variable. The variable types are listed here: https://serverless.com/framework/docs/providers/aws/guide/variables/

Nice! I know I read it somewhere like 4 days ago, but couldn’t find where.

By the way, as the docs states, environment variable should be using uppercase :wink:
process.env.NODE_ENV
