upload file in Nodejs using s3 npm package

Question

I am uploading video file using s3 bucket in Nodejs.

when I upload file on s3 bucket, it is also uploaded in temp/ folder. So after few video upload temp folder is become full due to this I can not upload more video.

How to remove this video from temp folder after file successfully or not upload on s3 bucket in Nodejs code?

I have used below package for s3 bucket. https://www.npmjs.com/package/s3

It's weird, there's no reason the file should be saved to a local directory without an explicit instruction to do so. As a workaround, you can always delete the temp folder after an upload — Jeremy Thille

var s3 = new AWS.S3();
s3.abortMultipartUpload(params, function (err, data) {
  if (err) console.log(err, err.stack); // USE BELOW CODE HERE
  else     console.log(data);           // ALSO HERE
});

Here is example of how can you remove/delete file from system using NodeJS

// include node fs module
var fs = require('fs');

// delete file named 'sample.txt'
fs.unlink('sample.txt', function (err) {
    if (err) throw err;
    // if no error, file has been deleted successfully
    console.log('File deleted!');
});

See my edited answer, look for comment in IF and ELSE You can use code in that sections. So that if s3 successfully saves file it will delete from system and evenn if s3 fail to do so it will remove the temp file.

const multer = require("multer");


require("dotenv").config();

const aws = require("aws-sdk");
const multerS3 = require("multer-s3");

aws.config.update({
  region: process.env.AWS_BUCKET_REGION,
  accessKeyId: process.env.AWS_ACCESS_KEY_ID,
  secretAccessKey: process.env.AWS_SECRET_KEY,
});

const BUCKET = process.env.AWS_BUCKET_NAME;
const s3 = new aws.S3();

// Multer config
module.exports = multer({
  storage: multerS3({
    bucket: BUCKET,
    s3: s3,
    contentType: multerS3.AUTO_CONTENT_TYPE,
    acl: "public-read",

    key: function (req, file, cb) {
      cb(null, Date.now() + file.originalname); //use Date.now() for unique file keys
    },
  }),
});
