Download File From Url And Upload It To Aws S3 Without Saving Node Js

Are you looking for a way to download a file from a URL and directly upload it to AWS S3 without the need to save it on your local machine using Node.js? You're in the right place! This guide will walk you through the process step by step, making it easy for you to achieve this seamlessly.

Node.js, with its powerful capabilities, allows you to perform a variety of tasks efficiently. When it comes to downloading a file from a URL and uploading it to AWS S3 without saving it locally, you can leverage Node.js along with the AWS SDK to streamline the process.

To get started, you'll need to have Node.js installed on your system. If you haven't already installed it, head over to the Node.js website and follow the instructions to set it up. Once you have Node.js up and running, you can proceed with the following steps:

1. Install Dependencies:
First, you need to install the `axios` and `aws-sdk` packages. You can do this by running the following commands in your terminal:

npm install axios aws-sdk

2. Writing the Code:
Now, it's time to write the Node.js code that will download a file from a URL and upload it to AWS S3 without saving it locally. Below is a sample code snippet to help you accomplish this task:

const axios = require('axios');
   const AWS = require('aws-sdk');

   const s3 = new AWS.S3({
       accessKeyId: 'YOUR_ACCESS_KEY_ID',
       secretAccessKey: 'YOUR_SECRET_ACCESS_KEY'
   });

   const downloadFileAndUploadToS3 = async (url, bucketName, key) => {
       const response = await axios.get(url, { responseType: 'arraybuffer' });
   
       const params = {
           Bucket: bucketName,
           Key: key,
           Body: response.data
       };
   
       try {
           await s3.upload(params).promise();
           console.log('File uploaded successfully to AWS S3!');
       } catch (err) {
           console.error('Error uploading file to S3:', err);
       }
   };

   // Usage
   const url = 'URL_TO_FILE';
   const bucketName = 'YOUR_BUCKET_NAME';
   const key = 'KEY_FOR_S3_OBJECT';

   downloadFileAndUploadToS3(url, bucketName, key);

3. Replace Credentials and Parameters:
Make sure to replace `'YOUR_ACCESS_KEY_ID'`, `'YOUR_SECRET_ACCESS_KEY'`, `'URL_TO_FILE'`, `'YOUR_BUCKET_NAME'`, and `'KEY_FOR_S3_OBJECT'` with your actual AWS credentials, URL from where the file needs to be downloaded, AWS S3 bucket name, and the key for the S3 object, respectively.

By following these steps and utilizing the provided code snippet, you'll be able to download a file from a URL and seamlessly upload it to AWS S3 without the need to save it on your local machine, using the power of Node.js. This efficient approach not only saves you time but also simplifies the file transfer process.
