Newline (formerly Fullstack.io) is the rebrand of the technical book and course publisher founded by Nate Murray and Ari Lerner — known for the ng-book Angular series, the fullstack React books, and a long list of comprehensive reference works that anchored a generation of working developers' deep-dives into modern JavaScript framework material. The Newline name reflects the platform's evolution beyond books into a full course catalog.
The catalog covers React (including Next.js, server components, the App Router era), TypeScript, GraphQL, Node.js, Vue, the testing tracks, AWS deployment, and the broader full-stack JavaScript ecosystem. Material is taught at the level of comprehensive reference works rather than introductory tutorials — Newline courses are typically the deep-dive after the introductory tutorial.
The CourseFlix listing under this source carries 10 Newline courses spanning that range. Material is paid; Newline runs on per-course pricing or membership on the original platform.
