An easy to use nestjs config module

import * as R from 'ramda';
import { parseValue } from "../utils/parse-value.js";
export function processEnvLoader(loaderOptions = {}) {
    const separator = loaderOptions.separator || '__';
    return () => {
        let config = {};
        for (const key of Object.keys(process.env)) {
            const value = parseValue(process.env[key], loaderOptions.jsonParse);
            config = R.assocPath(key.split(separator), value, config);
        }
        return config;
    };
}
