NextJS: How to access files in production deployment

[timtnleeProject]

Problem

My nextJS Apis have accessed some config files through the file system,
for example, the /posts folder under the project root.

import fs from "fs";
import path from "path";

const postsDirectory = path.join(process.cwd(), "posts");

const filenames = fs.readdirSync(postsDirectory); // failed in deployment

However, the folder structure has been optimized(? and is not as same as local development and local build.

So basically the /posts folder isn't there in the deployed environment.
