A Tech stack usually consists of the following Components

• Client Side: Users interact with the front-end, or client-side, software. Everything from the user experience to the style and design of the web page is included. Front-end frameworks like ReactJS or AngularJS, HTML, CSS, and JavaScript are examples of common technology.
• Server Side: Application logic, database interactions, user authentication, and server configuration take place on the back-end (server-side). Here, languages like Python, Ruby, and Java are frequently utilized, along with frameworks like Django or Node.js.
• APIs (Application Programming Interfaces): Application Programming Interfaces, or APIs, are interfaces that let the program interact with external services or with other components of the program.
• Databases: Databases handle and store the data used by an application. Relational databases like MySQL, PostgreSQL, and SQL Server; NoSQL databases like MongoDB, Firebase, and Cassandra; and cloud-based solutions like AWS DynamoDB and Google Cloud Firestore are just a few examples of the different kinds.

The collection of software tools, programming languages, frameworks, libraries, and other technologies needed to create a certain software application or system is known as a “Tech stack” in software development. In simple terms, it is the collection of all technological services required to construct and execute an application.
