Serverless Dotenv Component

Introduction

Inspired by serverless-dotenv-plugin.

Preload environment variables into serverless. If you have variables stored in a .env file that you want loaded into your serverless yaml config. This will allow you to reference them as ${Dotenv.env.VAR_NAME} inside your config(If you ).

Setup

Add @slsplus/dotenv in your serverless.yml, as below:

Dotenv:
  component: '@slsplus/dotenv'

Now create .env file in the project root:

TENCENT_SECRET_ID=xxx
TENCENT_SECRET_KEY=xxx

ABC=124

Automatic Env file name resolution

By default, the component looks for the file: .env. If you want different env files based on environment. For example:

.env.development
.env.production

Then you can exec deploy command like:

$ NODE_ENV=development serverless --debug

Or, like this:

$ serverless --debug --env development

Inject custom arguments to command

You can directly run deploy command with custom arguments:

$ serverless --debug --custom abc --custom1 123

Then you can use by process.env.custom and process.env.custom1
