Function getConfigType

Example

import { from } from 'env-var';

export const getConfigDefinitions = (
  variables: NodeJS.ProcessEnv = process.env,
) => {
  const env = from(variables);

  return {
   environment: () => env.get('NODE_ENV').required().asEnum(['development', 'production', 'test']),
   serviceId: () => env.get('SERVICE_ID').required().asString(),
   port: () => env.get('PORT').default(10100).asPortNumber(),
   // many more...
  }
}

// validation will not happen at that point in time
const config = getConfigType(getConfigDefinitions());
export type Config = typeof config;
