Mastering Next.js is a free video course for React and Next.js learners, created by Lee. The page notes that the course was originally released in 2019, and as Next.js has continued to evolve since v9, some of the content is now “outdated.” What stands out is that the author did not simply take the old course down. Instead, the syllabus marks lessons in green, yellow, and red to indicate “still relevant,” “changed,” and “not recommended,” making it more like a version-annotated archive of historical course material.
The course is delivered as pre-recorded videos, with a clear duration for each lesson, such as Introduction, React Overview, Developing Locally, Navigating Between Pages, Styling, Fetching Data, Managing Assets and SEO, and more. It covers React fundamentals, Props & State, Functional Components, React Hooks, ES6, and JSX, as well as Next.js topics including next dev/build/start, next/link, useRouter, API Routes, SWR, GraphQL, Hasura, SEO, and asset management. Some chapters include View Code, making it easier for learners to compare the implementation against the code.
The course’s biggest strength—and biggest risk—is that it is old. The author explicitly notes that topics such as Class Components, getInitialProps, Apollo Client, Custom Server, Sass, and Styled-Components have, in today’s context, been replaced to varying degrees or are no longer recommended. For example, React Hooks have become the standard, getInitialProps has largely been superseded by newer APIs, and ESLint is now integrated into Next.js. For beginners, these annotations are helpful, but they also require some judgment to avoid applying outdated practices directly to new projects.
The page clearly describes it as a free video course and does not show any paid pricing, subscription, or payment information, so the value for money is excellent. However, the content does not mention certificates, accreditation, assignment review, a learning community, 1-on-1 tutoring, or official Q&A support. It is better suited as reference material for self-learners rather than as a complete bootcamp-style course.
It is suitable for frontend developers with some English reading/listening ability who want to learn the basic React and Next.js workflow. It is also useful for users who have already worked with Next.js and want to review routing, styling, data fetching, and SEO by module. The page does not provide information about access from China, so it is not possible to determine whether it can be reached directly. If video or code resources are unstable, the official Next.js documentation, official React documentation, and newer Next.js courses on Chinese platforms can serve as alternatives. Overall, it is free and transparent, but it should not be used as the only resource for learning the latest version of Next.js.
