Familiarity with Node.js and fundamental concepts of web development will also be beneficial. Additionally, you need to install Insomnia, a tool used for interacting with GraphQL APIs, as covered in the course's prerequisite lesson.
What will I build by the end of this course?
By the end of the course, you will have built a working GraphQL application using the NestJS framework. The project will include the implementation of types, queries, mutations, and subscriptions, providing real-time updates. You will also learn to connect to a database using TypeOrm and handle data manipulation through services and repositories.
Who is the target audience for this course?
This course is designed for developers who are interested in building applications with GraphQL using NestJS.

It caters to both intermediate and advanced developers looking to expand their skill set in modern web application development.
What specific tools and platforms are covered in the course?
The course specifically covers the NestJS framework and its integration with GraphQL. You will learn to use TypeOrm for database connectivity and Insomnia for testing GraphQL APIs. The course also explores the use of Data Loader for batching and caching queries, enhancing the efficiency of your application.
How does the content of this course compare to other NestJS courses?
This course focuses on the code-first approach to building GraphQL applications with NestJS, which differs from the schema-first approach covered in some other courses. It provides a step-by-step guide to implementing key GraphQL features like types, queries, mutations, and subscriptions, and includes lessons on advanced topics such as custom scalar types and field middleware.
What topics are not covered in this course?
The course does not cover the schema-first approach to building GraphQL applications, as it focuses exclusively on the code-first methodology. It also does not delve into frontend development or connecting GraphQL with different client-side frameworks, as the emphasis is on server-side application development using NestJS.
What time commitment is required to complete the course?
The course consists of 24 lessons with a total runtime of approximately 1 hour and 55 minutes. This includes 23 short videos with subtitles that guide you through the process of building a GraphQL app in NestJS.
