A course on TanStack Query built with the library's own maintainers, covering the mental model of server-state caching rather than a list of API options. Eight sections run from basic queries through advanced patterns, mutations and user interaction, scaling, plugins and adapters, and testing, with bonus material on server-side rendering, Suspense and WebSockets. Sold in the same three tiers as its sibling course, with the two purchase tiers granting lifetime access.

Who it is for

React developers already fetching data who keep reinventing caching, refetching and invalidation by hand.

Recorded from the provider’s published description of the course.

What the course covers

Summarised by TrustMyCourse from public course information. Wording is our own, not the provider’s.

  1. Laying the Foundation

    The problem server-state caching solves, before the library's API is introduced.

  2. Querying Data

    The basic read path: fetching, caching and the states a query moves through.

  3. Advanced Query Patterns

    Dependent, parallel and paginated queries and the patterns they need.

  4. Handling User Interactions

    Mutations and keeping cached data correct after the user changes something.

  5. Scaling Your App

    Organising query usage once an application outgrows a handful of screens.

  6. Plugins & Adapters

    Extending the library and using it outside its default environment.

  7. Testing

    Testing components whose behaviour depends on cached asynchronous state.

  8. Bonus content

    Server-side rendering, Suspense integration and WebSockets, included as additional material.

    Harvard University (CS50)

    Artificial Intelligence

    CS50's Introduction to Artificial Intelligence with Python

    Harvard's AI course, published free as OpenCourseWare. Seven lecture topics work through search, knowledge representation, uncertainty, optimisation, machine learning, neural networks and language, with Python projects attached to each. It is explicitly a follow-on rather than a first course: the stated prerequisite is CS50x or roughly a year of Python experience, and the material assumes the learner can already write and debug their own programs.

    Programming

    CS50's Introduction to Computer Science

    Harvard's introductory computer science course, taught through eleven weeks that begin in Scratch and move into C, then Python, SQL and web development with Flask. It spends unusually long on what happens underneath a program, covering arrays, memory, pointers and data structures, before reaching higher-level languages, and ends with a self-directed final project. The course materials are free; a certificate is a separate paid option through edX.
