how can I use process.env in serverless.ts?

I am using the serverless framework to deploy some REST APIs. Earlier I was using serverless.yml and now migrating to the typescript version. I am having some AWS keys which I would like to keep in env files and not add directly. Earlier I was adding them directly.

I am trying to do something like the below:

export const serverless = {
    frameworkVersion: '3',
    useDotenv : true,
    plugins: ['serverless-webpack', 'serverless-offline'],
    provider: {
        name: 'aws',
        runtime: 'nodejs14.x',
        stage: process.env.stage,  // check this
        profile: process.env.stage === 'dev ? 'dev' : 'prod', // check this
        region: process.env.region,
    },
};

this is not working. I tried logging the env variables and above object but it's coming as empty. I have already tried using this plugin- https://github.com/neverendingqs/serverless-dotenv-plugin

it seems that, env variables are loaded after serverless.ts file.

should I stick to using - ${self:custom.stage} syntax. I was trying to avoid this. or Is it possible to use process.env?

Edit:

when trying to use syntax - ${env:profile}

Cannot resolve variable at "provider.profile": Value not found at "env" source

To access env variables in serverless configuration use ${env:VARIABLE_NAME}. For the stage: for me ${opt:stage} works when running sls --stage STAGE_NAME.

In your case:

export const serverless = {
    frameworkVersion: '3',
    useDotenv : true,
    plugins: ['serverless-webpack', 'serverless-offline'],
    provider: {
        name: 'aws',
        runtime: 'nodejs14.x',
        stage: '${opt:stage}', 
        profile: ${opt:stage, 'prod'}, // if no --stage default to 'prod'
        region: '${env:region}',
    },
};
