Strapi Interview Questions and Answers for internship

1. What is Strapi?

   • Answer: Strapi is a popular open-source headless CMS (Content Management System) built on Node.js. It allows developers to manage content through a user-friendly admin panel and expose that content via a RESTful API or GraphQL, making it ideal for building modern websites and applications.

2. What are the benefits of using a headless CMS like Strapi?

   • Answer: Headless CMSs offer several advantages, including decoupling the frontend and backend, enabling content delivery to multiple platforms (web, mobile, IoT), greater flexibility in content presentation, improved content scalability, and easier content management for non-technical users.

3. How does Strapi differ from other headless CMSs?

   • Answer: Strapi differentiates itself through its flexibility, ease of use, extensive plugin ecosystem, and active community support. It's known for its developer-friendly approach and its ability to be customized extensively.

4. Explain the concept of "headless" in a headless CMS.

   • Answer: "Headless" refers to the separation of the content repository (backend) from the presentation layer (frontend). Traditional CMSs have a tightly coupled frontend, whereas headless CMSs provide an API to access the content, allowing developers to use any frontend technology they prefer.

5. Describe the architecture of a Strapi application.

   • Answer: Strapi's architecture is based on a RESTful API built on Node.js and Express.js. It uses a database (like PostgreSQL, MySQL, MongoDB) to store content. The admin panel is a separate application that interacts with the API. Content is modeled using Content Types.

6. How do you create a new content type in Strapi?

8. What are relationships in Strapi, and how are they used?

   • Answer: Relationships define connections between different content types.

They enable you to build complex data structures.
