A code for a file-based JAMstack CMS system using JavaScript

Posted on February 11, 2023

Here's an example of how you could write a code for a file-based JAMstack CMS system using JavaScript:

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

const dataDirectory = path.join(__dirname, 'data');

const getData = () => {
  return new Promise((resolve, reject) => {
    fs.readdir(dataDirectory, (error, files) => {
      if (error) {
        reject(error);
      }

      const promises = files.map(file => {
        return new Promise((resolve, reject) => {
          fs.readFile(path.join(dataDirectory, file), 'utf-8', (error, content) => {
            if (error) {
              reject(error);
            }

            resolve({
              fileName: file,
              content: content
            });
          });
        });
      });

      Promise.all(promises)
        .then(results => {
          resolve(results);
        })
        .catch(error => {
          reject(error);
        });
    });
  });
};

const saveData = (fileName, content) => {
  return new Promise((resolve, reject) => {
    fs.writeFile(path.join(dataDirectory, fileName), content, 'utf-8', error => {
      if (error) {
        reject(error);
      }

      resolve();
    });
  });
};

module.exports = {
  getData,
  saveData
};

This code exports two functions: getData and saveData. The getData function reads the contents of the data directory and returns an array of objects, each representing a file and its contents. The saveData function saves a file with the specified fileName and content to the data directory.

Note: This is just a simple example to demonstrate the concept of a file-based JAMstack CMS system, and it doesn't handle error cases such as missing directories, or duplicated file names, among others. You may want to add additional error handling and validation in a real-world implementation.
