Learn how to use PyScript and Pyodide to manipulate the DOM and create reactive web interfaces using Python, including a practical example of event handling and performance trade-offs.
Learn how Firefox’s WebAssembly SIMD extension (available from version 94) lets you accelerate numeric workloads with minimal code changes, plus a hands‑on example and caveats.
A practical guide to deciding whether WebAssembly SIMD (128‑bit) vectors will give you a measurable speed‑up for tight loops, with a concrete dot‑product example, build steps, and compatibility considerations.
Learn how PyScript's <py-env> tag lets you declare Python package dependencies directly in HTML, letting micropip fetch and install them automatically.
Learn how to lazy load assemblies in Blazor WebAssembly to cut the initial download size, with a csproj snippet, component example, and common pitfalls to avoid.
PyScript's <py-config> tag declares Python packages in TOML/JSON; micropip installs WASM wheels at load time, caching them in IndexedDB. Works for pure-Python and Pyodide-built binaries, but lacks full dependency resolution and fails on missing wheels.
WASI turns WebAssembly into a practical server‑side runtime by providing a sandboxed I/O API. Learn how to compile, run, and secure a WASI module with Wasmtime, and understand the trade‑offs for production use.
Learn how to load external Python packages in the browser using PyScript’s <code><py-config></code> tag, with a hands‑on example, performance trade‑offs, and a practical checklist for production.
Learn how to use WebAssembly.instantiateStreaming for efficient, incremental loading of .wasm modules, the MIME‑type requirement, and a robust arrayBuffer fallback for misconfigured servers. Follow the step‑by‑step guide to reduce load times and avoid common deployment pitfalls.
