How do I delete a file with node.js?

I don't see a remove command?

I think you want to use fs.unlink.

More info on fs can be found here.

You can call fs.unlink(path, callback) for Asynchronous unlink(2) or fs.unlinkSync(path) for Synchronous unlink(2).
Where path is file-path which you want to remove.

For example we want to remove discovery.docx file from c:/book directory. So my file-path is c:/book/discovery.docx. So code for removing that file will be,

var fs = require('fs'); var filePath = 'c:/book/discovery.docx'; fs.unlinkSync(filePath); 

If you want to check file before delete whether it exist or not. So, use fs.stat or fs.statSync (Synchronous) instead of fs.exists. Because according to the latest node.js documentation, fs.exists now deprecated.

For example:-

 fs.stat('./server/upload/my.csv', function (err, stats) { console.log(stats);//here we got all information of file in stats variable if (err) { return console.error(err); } fs.unlink('./server/upload/my.csv',function(err){ if(err) return console.log(err); console.log('file deleted successfully'); }); }); 

I don't think you have to check if file exists or not, fs.unlink will check it for you.

fs.unlink('fileToBeRemoved', function(err) { if(err && err.code == 'ENOENT') { // file doens't exist console.info("File doesn't exist, won't remove it."); } else if (err) { // other errors, e.g. maybe we don't have enough permission console.error("Error occurred while trying to remove file"); } else { console.info(`removed`); } }); 

Here is a small snippet of I made for this purpose,

var fs = require('fs'); var gutil = require('gulp-util'); fs.exists('./www/index.html', function(exists) { if(exists) { //Show in green console.log(gutil.colors.green('File exists. Deleting now ...')); fs.unlink('./www/index.html'); } else { //Show in red console.log(gutil.colors.red('File not found, so not deleting.')); } }); 

2019 and Node 10+ is here. Below the version using sweet async/await way.

Now no need to wrap fs.unlink into Promises nor to use additional packages (like fs-extra) anymore.

Just use native fs Promises API.

const fs = require('fs').promises; (async () => { try { await fs.unlink('~/any/file'); } catch (e) { // file doesn't exist, no permissions, etc.. // full list of possible errors is here // console.log(e); } })(); 

Here is fsPromises.unlink spec from Node docs.

Also please note that fs.promises API marked as experimental in Node 10.x.x (but works totally fine, though), and no longer experimental since 11.14.0.

With the release of node v14.14.0 you can now do.

fs.rmSync("path/to/file", { force: true, }); 

As the accepted answer, use fs.unlink to delete files.

But according to Node.js documentation

Using fs.stat() to check for the existence of a file before calling fs.open(), fs.readFile() or fs.writeFile() is not recommended. Instead, user code should open/read/write the file directly and handle the error raised if the file is not available.

To check if a file exists without manipulating it afterwards, fs.access() is recommended.

to check files can be deleted or not, Use fs.access instead

fs.access('/etc/passwd', fs.constants.R_OK | fs.constants.W_OK, (err) => { console.log(err ? 'no access!' : 'can read/write'); }); 

Here below my code which works fine.

 const fs = require('fs'); fs.unlink(__dirname+ '/test.txt', function (err) { if (err) { console.error(err); } console.log('File has been Deleted'); }); 

Simple and sync

if (fs.existsSync(pathToFile)) { fs.unlinkSync(pathToFile) } 

You can do the following thing

const deleteFile = './docs/deleteme.txt' if (fs.existsSync(deleteFile)) { fs.unlink(deleteFile, (err) => { if (err) { console.log(err); } console.log('deleted'); }) } 

• fs.unlinkSync() if you want to remove files synchronously and
• fs.unlink() if you want to remove it asynchronously.

Here you can find a good article.

Just rm -rf it

require("fs").rmSync(file_or_directory_path_existing_or_not, {recursive: true, force: true}); // Added in Node.js 14.14.0. 

with require("fs").rmSync or require("fs").rm.

you can use del module to remove one or more files in the current directory. what's nice about it is that protects you against deleting the current working directory and above.

const del = require('del'); del(['<your pathere here>/*']).then( (paths: any) => { console.log('Deleted files and folders:\n', paths.join('\n')); }); 

You may use fs.unlink(path, callback) function. Here is an example of the function wrapper with "error-back" pattern:

// Dependencies. const fs = require('fs'); // Delete a file. const deleteFile = (filePath, callback) => { // Unlink the file. fs.unlink(filePath, (error) => { if (!error) { callback(false); } else { callback('Error deleting the file'); } }) };

Remove files from the directory that matched regexp for filename. Used only fs.unlink - to remove file, fs.readdir - to get all files from a directory

var fs = require('fs'); const path = '/path_to_files/filename.anyextension'; const removeFile = (fileName) => { fs.unlink(`${path}${fileName}`, function(error) { if (error) { throw error; } console.log('Deleted filename', fileName); }) } const reg = /^[a-zA-Z]+_[0-9]+(\s[2-4])+\./ fs.readdir(path, function(err, items) { for (var i=0; i<items.length; i++) { console.log(items[i], ' ', reg.test(items[i])) if (reg.test(items[i])) { console.log(items[i]) removeFile(items[i]) } } }); 

It's very easy with fs.

var fs = require('fs'); try{ var sourceUrls = "/sampleFolder/sampleFile.txt"; fs.unlinkSync(sourceUrls); }catch(err){ console.log(err); } 

fs-extra provides a remove method:

const fs = require('fs-extra') fs.remove('/tmp/myfile') .then(() => { console.log('success!') }) .catch(err => { console.error(err) }) 

Use NPM module fs-extra, which gives you everything in fs, plus everything is Promisified. As a bonus, there's a fs.remove() method available.

Never do any sync operation in Nodejs

To asynchronously delete a file,

const { unlink } = require('fs/promises'); (async function(path) { try { await unlink(path); console.log(`successfully deleted ${path}`); } catch (error) { console.error('there was an error:', error.message); } })('/tmp/hello'); 

ref:

It is recommended to check file exists before deleting using access or stat

import { access, constants } from 'fs'; const file = 'package.json'; // Check if the file exists in the current directory. access(file, constants.F_OK, (err) => { console.log(`${file} ${err ? 'does not exist' : 'exists'}`); }); 

ref:

You can use the below code. I think it works.

const fs = require('fs'); fs.unlink('./uploads/file.png', function (err) { if (err) { console.error(err); console.log('File not found'); }else{ console.log('File Delete Successfuly'); } }); 

Here the code where you can delete file/image from folder.

var fs = require('fs'); Gallery.findById({ _id: req.params.id},function(err,data){ if (err) throw err; fs.unlink('public/gallery/'+data.image_name); });
