The Node.js fs core module provides many handy methods you can use to work with folders.<\/p>\n

Check if a folder exists<\/p>\n

Use fs.access() to check if the folder exists and Node can access it with its permissions.<\/p>\n

Create a new folder<\/strong><\/p>\n

Use fs.mkdir() or fs.mkdirSync() to create a new folder.<\/p>\n

const fs = require(‘fs’)<\/p>\n

const folderName = ‘\/Users\/flavio\/test’<\/p>\n

try {<\/p>\n

if (!fs.existsSync(dir)){<\/p>\n

fs.mkdirSync(dir)<\/p>\n

}<\/p>\n

} catch (err) {<\/p>\n

console.error(err)<\/p>\n

}<\/p>\n

Read the content of a directory<\/p>\n

Use fs.readdir() or fs.readdirSync to read the contents of a directory.<\/p>\n

This piece of code reads the content of a folder, both files and subfolders, and returns their relative path:<\/p>\n

const fs = require(‘fs’)<\/p>\n

const path = require(‘path’)<\/p>\n

const folderPath = ‘\/Users\/flavio’<\/p>\n

fs.readdirSync(folderPath)<\/p>\n

You can get the full path:<\/p>\n

fs.readdirSync(folderPath).map(fileName => {<\/p>\n

return path.join(folderPath, fileName)<\/p>\n

}<\/p>\n

You can also filter the results to only return the files, and exclude the folders:<\/p>\n

const isFile = fileName => {<\/p>\n

return fs.lstatSync(fileName).isFile()<\/p>\n

}<\/p>\n

fs.readdirSync(folderPath).map(fileName => {<\/p>\n

return path.join(folderPath, fileName)).filter(isFile)<\/p>\n

}<\/p>\n

Rename a folder<\/p>\n

Use fs.rename() or fs.renameSync() to rename folder. The first parameter is the current path, the second the new path:<\/p>\n

const fs = require(‘fs’)<\/p>\n

fs.rename(‘\/Users\/flavio’, ‘\/Users\/roger’, (err) => {<\/p>\n

if (err) {<\/p>\n

console.error(err)<\/p>\n

return<\/p>\n

}<\/p>\n

\/\/done<\/p>\n

})<\/p>\n

fs.renameSync() is the synchronous version:<\/p>\n

const fs = require(‘fs’)<\/p>\n

try {<\/p>\n

fs.renameSync(‘\/Users\/flavio’, ‘\/Users\/roger’)<\/p>\n

} catch (err) {<\/p>\n

console.error(err)<\/p>\n

}<\/p>\n

Remove a folder<\/p>\n

Use fs.rmdir() or fs.rmdirSync() to remove a folder.<\/p>\n

Removing a folder that has content can be more complicated than you need.<\/p>\n

In this case I recommend installing the fs-extra module, which is very popular and well maintained, and it\u2019s a drop-in replacement of the fs module, providing more features on top of it.<\/p>\n

In this case the remove() method is what you want.<\/p>\n

Install it using<\/p>\n

npm install fs-extra<\/p>\n

and use it like this:<\/p>\n

const fs = require(‘fs-extra’)<\/p>\n

const folder = ‘\/Users\/flavio’<\/p>\n

fs.remove(folder, err => {<\/p>\n

console.error(err)<\/p>\n

})<\/p>\n

It can also be used with promises:<\/p>\n

fs.remove(folder).then(() => {<\/p>\n

\/\/done<\/p>\n

}).catch(err => {<\/p>\n

console.error(err)<\/p>\n

})<\/p>\n

or with async\/await:<\/p>\n

async function removeFolder(folder) {<\/p>\n

try {<\/p>\n

await fs.remove(folder)<\/p>\n

\/\/done<\/p>\n

} catch (err) {<\/p>\n

console.error(err)<\/p>\n

}<\/p>\n

}<\/p>\n

const folder = ‘\/Users\/flavio’<\/p>\n

removeFolder(folder)<\/p>\n\n\n
