JS frameworks like Next.js and Remix have evolved to support full stack development, prompting the development of similar capabilities in DevTools. Replay, a tool for Full Stack DevTools, allows developers to inspect both browser and server contexts simultaneously, unlike traditional DevTools which limit inspection to one at a time. Features like the Network Monitor display requests from both browser and Node contexts, enabling navigation between client requests and server responses, while Live Console Logs provide real-time insights into sources and hit counts across processes. The tool is currently being refined with next-generation React inspection capabilities and discussions are underway with cloud providers to integrate Replay into CI and production environments. Although Full Stack DevTools is still experimental and based on an alpha Node recorder, the team is keen to gather community feedback and collaborate with partners without making premature promises.
