This is second part of the blog. To follow along, visit my previous blog to set up AWS S3 — bucket policy,configuration etc.

This blog has two parts:

Part I — Learn how to setup aws s3 and manually use it.

Part II — Using node js programatically perform operations on S3.

What are we building?

In this blog we will see node js implementation to do the following:

1. Create bucket on S3 (like a specific unique folder to store our media)
2. List out all the buckets made by us.
3. Upload images to the bucket.
4. List out all the objects(images,videos etc) in the bucket
5. …

Introduction

Most of the websites require hosting to host images,videos etc. One obvious way to do it is to store it in hard drive. That seems alright but what if size of this storage required exceeds to hard drive storage limit. We will need to scale it accordingly which is a bit tedious task. So here hosting service like AWS S3 comes into picture which can store huge amount of media files and can scale accordingly.

Introduction

As a beginner i always used to wonder how image data is stored. Is it like a folder containing thousands and thousands of images or is it stored as string in database.

Well the answer is image file is stored on some cloud storage service like cloudinary or AWS S3 and the image’s url is stored in database.

In this blog we will see rather than storing image on a folder locally, how can we save image on cloud storage service (cloudinary) and use image’s url.

We will use cloudinary because it requires minimum setup and is easy to use.
