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

Answer 1

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!');
}); 

Answer 2

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
    },
  }),
});
