Port subscription lifecycle in Elm 0.19.1 The goal is to decide whether the Elm runtime should automatically unsubscribe JavaScript ports when a component that created the subscription is removed from the DOM, thereby preventing memory leaks that currently require manual tracking. Constraints include maintaining backward compatibility with existing code that
Linear Memory Management WebAssembly modules utilize a sandboxed linear memory model where memory is expanded in 64 KiB pages via the memory.grow instruction. In browser environments, this memory is typically exported as a WebAssembly.Memory object, providing a handle to the underlying ArrayBuffer . Buffer Detachment Behavior When a module successfully execu
PyScript utilizes Pyodide to bridge the Python interpreter with the browser's JavaScript DOM API. A core requirement for complex web applications is the ability to maintain a consistent global state across both environments, specifically when modifying the JavaScript window object from within a PyScript execution block. While the runtime provides mechanisms
Runtime Configuration Transition PyScript Next (version 2023.11.1+) has transitioned to a decoupled configuration model using the <py-config> tag. This modular approach allows developers to switch between the Pyodide and MicroPython backends depending on the required footprint and library support. Namespace Synchronization Uncertainty While the <py-
A small frontend application is being considered for incremental migration from plain JavaScript to ClojureScript with no downtime. The goal is to mount ClojureScript components into isolated DOM nodes and routes while the existing JavaScript remains active, using feature flags and separate asset loading. ClojureScript compiles to plain JavaScript and can be
Incremental JavaScript-to-PureScript migration with a shared FFI boundary I am migrating a small browser application from plain JavaScript to PureScript one module at a time, and both sides must keep running together in production during the transition. The plan is to wrap the remaining JavaScript modules behind foreign import declarations so new PureScript
Elm ports provide typed channels for JavaScript interop. The compiler validates port types at compile time, but does not enforce a visibility boundary for which ports are exposed to JavaScript. All ports defined in a module are automatically exported from the module and become accessible to JavaScript consumers. There is no built-in mechanism to mark a port
