How to declare Python dependencies in PyScript's py-config, which packages actually load in the Pyodide runtime, and the compatibility and performance limits that decide whether PyScript fits your project.
When a WebAssembly module fails to instantiate with a SIMD error, this guide walks through detection, root‑cause analysis, and corrective actions across browsers and build pipelines.
An architecture note on using WebAssembly bulk memory instructions (memory.fill, memory.copy, memory.init) for fast, safe data movement across module boundaries, covering requirements, minimal design, trust boundaries, operational checks, failure modes, and when to reconsider the approach.
Learn how to manage dependencies and DOM interaction in PyScript using the py-config tag and Pyodide FFI to run Python in the browser.
Learn how Blazor WebAssembly’s ‑pwa flag scaffolds a service worker, what assets get cached, and how to verify offline functionality. A step‑by‑step example shows bundle impact, trade‑offs, and how to customize caching.
A successful memory.grow detaches the ArrayBuffer behind WebAssembly memory, silently zeroing cached views. Here is a view cache that survives growth.
Learn how to use PyScript’s built‑in js module to call browser APIs such as fetch and DOM methods directly from Python, with a worked example, setup steps, and performance considerations.
Discover how Jeet’s streamlined compiler pipeline cuts build times and binary size, boosting web app startup speed. A hands‑on example shows real gains over the classic LLVM toolchain.
Learn how to enable WebAssembly SIMD in a Rust project, verify vector instruction emission, and measure speedups for data‑parallel browser workloads while understanding fallback and debugging trade‑offs.
