Read Content of All Files Inside a Folder Using Node.js

Published on 22 Jul, 2021

Sometimes we require to read the contents of all files in a folder. It can be to pre-render static pages or for some other reason. Let us see how we can do that using Node.js.

Here index.js and blog directory are in same folder. Here are the contents of index.js file.

const path = require("path");
const fs = require("fs");

const blogPath = path.join(process.cwd(), "blog");
const filenames = fs.readdirSync(blogPath);
const filePosts = filenames.map((name) => {
  const fullPath = path.join(process.cwd(), "blog", name);
  const file = fs.readFileSync(fullPath, "utf-8");
  console.log(file);
});

path and fs comes with Node.js. They are included on top.

process.cwd() returns current directory. path.join() returns the full path string.

fs.readdirSync gets all file names synchronously. fs.readFileSync gets the content of the file.
