What is mem-fs-editor?

The mem-fs-editor package is a utility for working with the file system in memory. It provides a way to perform file operations such as reading, writing, and modifying files without directly interacting with the disk until you decide to commit the changes. This is particularly useful for scaffolding tools and generators.

What are mem-fs-editor's main functionalities?

Reading Files

This feature allows you to read the content of a file from the file system into memory. The code sample demonstrates how to read a file using mem-fs-editor.

const memFs = require('mem-fs');
const editor = require('mem-fs-editor');
const store = memFs.create();
const fs = editor.create(store);

const content = fs.read('path/to/file.txt');
console.log(content);

Writing Files

This feature allows you to write content to a file in memory and then commit the changes to the disk. The code sample demonstrates how to write to a file and commit the changes.

const memFs = require('mem-fs');
const editor = require('mem-fs-editor');
const store = memFs.create();
const fs = editor.create(store);

fs.write('path/to/file.txt', 'Hello, World!');
fs.commit(() => {
  console.log('File written to disk');
});

Modifying Files

const memFs = require('mem-fs');
const editor = require('mem-fs-editor');
const store = memFs.create();
