1- Getting Started With Repo

First Clone the repo

git clone https://github.com/Muhammad-Bilal-7896/CRUDCassandraDBNextJS

Then install the dependencies

npm install

Then create a .env.local file in the root directory and add the following

REACT_APP_ASTRA_DB_ID=70271e02-9616-4b61-8902-f8cd73d5b470
REACT_APP_ASTRA_DB_REGION=us-east1
REACT_APP_ASTRA_DB_KEYSPACE=live_coding
REACT_APP_ASTRA_DB_TOKEN=AstraCS:UMHldokDeYIhSkNHRHDuIShI:71cef8c7f57909521b2eb550d593e8cf0bc399521633e8fc5c525fa8ee2cb928

Then run the development server:

npm run dev
# or
yarn dev
# or
pnpm dev

Open http://localhost:3000 with your browser to see the result.

For detailed explanation on how I built this app, read below.

2- What We Are Going to Build?

We are going to build a simple todo app that will use Apache Cassandra to store the todos, and addition, deletion, and update of todos will be handled by Apache Cassandra.

We will discuss the following in detail:

• Overview of Apache Cassandra
• Cassandra Data Modeling
• Cassandra DB Structure
• Creating a new serverless Astra DB Database and utilizing its API using NextJS that will perform CRUD (create, read, update, delete) operations utilizing Astra DB
• Build a front end using Next JS to utilize that API

At the end of the article, we will be ready with a full stack Cassandra DB todo app. I will do everything from scratch so that every beginner can understand, and everything will be step by step.

3- Technologies We Are Going to Use

• Database: Apache Cassandra, Astra DB
• Front End: Next JS
• UI Libraries: Material UI, Tailwind CSS
• Language: TypeScript

This project will not only add a new database skill, but you will also learn how to develop and use AstraDB with a front end (NextJS). I hope you will be able to follow everything step by step. Otherwise, if you face any difficulty, you can always reach out to me or comment on the post. I will be happy to help you resolve the issue.

A full stack Next js + Cassandra Db Todo app that will perform all major AstraDB database functions this guide is designed for this purpose.

3- Are Apache Cassandra and Serverless Astra DB Different?

Astra DB is a serverless database like Firebase that is built using Apache Cassandra and is fully hosted and managed by DataStax so developers can easily use it without building the backend. So it can be used on the front end without building the API just as if any of you have used Firebase, Astra DB by DataStax is similar to that.
Cassandra DB is a free and open-source, distributed, wide-column store, NoSQL database management system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure.
We will be using Astra DB provided by DataStax to use Cassandra DB throughout this article.

4- Pre-requisites for following this article

1. JavaScript basic knowledge 2. Rest API's basic knowledge 3. NextJS basic concepts 4. NodeJS basic knowledge
Now let's first understand what is Cassandra

5- Introduction to Cassandra

"Cassandra is an open source and free database written in java and is a wide column store nosql database famous for its ability to distribute petabytes of data with unmatched reliability and performance".
