Understanding REPL Bridge and the Transport Layer
Introduction Interactive programming environments—commonly known as REPLs (Read‑Eval‑Print Loops)—have become a cornerstone of modern software development. From Python’s >>> prompt to JavaScript’s Node console, developers rely on REPLs for rapid prototyping, debugging, and teaching. As applications scale and move beyond the local machine, the need to bridge a REPL session across process, container, or network boundaries emerges. This bridge must reliably transport commands, results, and side‑effects while preserving the REPL semantics that users expect. ...
