Serverless Doppler

It makes it easier to use Doppler without setup in serverless.

How to use?

First, install the package by entering the following command.

npm install -D serverless-doppler

Then, add the line below to serverless.yml.

plugins:
  - serverless-doppler

If you already have a project setting with the Doppler CLI, it is automatically called, so you do not need to set anything.

Congratulations. Automatically specifies the environment variable at run time.

⚠️ In an deployed environment (ex: lambda), the environment variable is not automatically updated. You must manually deploy it manually when updating.

Successful console log:

Loaded Doppler settings. (project: <PROJECT NAME>, config: <CONFIG>)
Loading environment variables from Doppler...
The environment variables below are applied.
  - DOPPLER_PROJECT
  - DOPPLER_ENVIRONMENT
  - DOPPLER_CONFIG

Additional settings

You can add the following options:

Config	Description	Default
project	Doppler project name	Doppler calls automatically via CLI
token	Doppler token	Doppler calls automatically via CLI
config	Doppler config	Same as serverless stage ${sls:stage}

custom:
  doppler:
    project: <DOPPLER PROJECT>
    config: <DOPPLER CONFIG>
    token: <DOPPLER TOKEN>
