Env variables set in serverless.yml not being built

I need to read environment variables in my lambda function. It looks like the environment variables from the serverless config are not actually set at build time when the code is transpiled - therefore undefined in the output. I have created a bash script to set them then run serverless deploy, but is there already a solution for this?

I have the following in my function config:

    environment:
      MONGO_URI:  ${file(${opt:secrets}):MONGO_URI}

and my webpack config for EnvironmentPlugin:

    plugins: [
      new webpack.EnvironmentPlugin(['NODE_ENV', 'MONGO_URI']),
    ],

    "serverless-webpack": "^3.0.0-rc.1",
    "webpack": "^3.5.6"

👋 Just wanted to note that you forgot the lib property in your example to access the top level env object:

slsw.lib.serverless.service.provider.environment
