GraphQL offers a more efficient and flexible way to build APIs compared to traditional REST architecture.The article discusses the benefits of using GraphQL over REST, highlighting its ability to fetch specific data efficiently.Building a GraphQL API with Prisma, SQLite, and Node.js allows for faster full-stack application development and cleaner backend code.The project in the article focuses on creating a 'Task Manager' API for tasks creation, completion, and retrieval.Key lessons learned include the power of GraphQL in giving clients control and the efficiency of Prisma ORM for database operations.Setting up the project involves installing necessary dependencies, configuring the database with Prisma and SQLite, and building the GraphQL server.Testing the API is done using GraphiQL to fetch tasks, create new tasks, and mark tasks as completed.GraphQL's optimization of data fetching, by dynamically retrieving specific data requested by clients, improves performance and reduces payload size.By completing the project, developers gain a foundational understanding of GraphQL, Prisma, and SQLite for future fullstack development.Future enhancements to the project can include TypeScript implementation, Prisma validation, and real-time subscriptions for improved functionality.
