Helper function which ensures that required environment variables are set.

export const fromEnv = (def) => (env) => Object.entries(def).reduce((res, [defKey, envKey]) => {
    const v = env[envKey];
    if (v === undefined || v.length === 0)
        throw new Error(`${envKey} is not defined in environment!`);
    return { ...res, [defKey]: v };
}, {});
