React Apps with Remix


5 Days


This comprehensive course on "React Apps with Remix" offers an in-depth exploration of modern web development using React and Remix, highlighting their unique solutions to contemporary web development challenges. Participants will delve into the intricate architecture of Remix, including key aspects like React Router and server-side handling, while mastering the setup of a robust development environment with tools like Node.js and Visual Studio Code. The course emphasizes practical skills in creating and managing Remix projects, from understanding folder structures to managing styles and dependencies. Students will also gain hands-on experience in advanced React concepts, such as component props, events, and hooks, and explore full-stack development features like isomorphic rendering and progressive enhancement. The curriculum culminates in teaching essential styling techniques, effective unit testing, and deploying a fully functional React application using Remix.


  • Grasp why React and Remix are chosen for modern web development and the specific problems they solve.
  • Dive into Remix's architecture, including React Router, Compiler, server-side HTTP handling, Web Fetch API, and understanding both server and browser frameworks.
  • Master setting up a development environment, including installing Node.js, configuring Visual Studio Code, React Developer Tools, and Remix NPM packages.
  • Learn to create and manage a Remix project, understanding folder structures, browser support, handling styles and assets, and managing dependencies.
  • Gain proficiency in creating and rendering React components, understanding JSX, and optimizing rendering with keys and various JSX operators.
  • Master advanced concepts like component props, events, and hooks, including state, effect, callback, and custom hooks.
  • Explore Remix's full-stack capabilities including isomorphic rendering, progressive enhancement, pending UI concepts, state management, and network concurrency.
  • Learn styling techniques (CSS Modules, Tailwind CSS, CSS-in-JS), unit testing (Jest, Testing Library), and deploy a fully functional React app with Remix.


All attendees must have experience with modern JavaScript or TypeScript, including the new language features like classes, modules, arrow functions, and destructuring.

Training Materials

All students receive comprehensive courseware covering all topics in the course. Courseware is distributed via GitHub in the form of documentation and extensive code samples. Students practice the topics covered through challenging hands-on lab exercises.

Software Requirements

Students will need a free, personal GitHub account to access the courseware. Students will need permission to install Node.js and Visual Studio Code on their computers. Also, students will need permission to install NPM Packages and Visual Studio Extensions. If students are unable to configure a local environment, a cloud-based environment can be provided.
