PyScript lets Python run in the browser and talk directly to the DOM, removing the need for a server round trip for lightweight logic. This post walks through a concrete example, the trade-offs, and how to verify it works.
Running Python in a PyScript Web Worker keeps the browser UI smooth. Learn why, how to set it up, and what trade‑offs you’ll face.
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.
Design a PyScript web app by managing package fetching, respecting Same‑Origin limits, and choosing the right WASM runtime. This guide covers architecture, diagnostics, failure modes, and when to shift to a server‑side solution.
A diagnostic guide for troubleshooting <py-config> package loading failures in PyScript, covering tag placement, CSP violations, and pure-Python wheel compatibility.
Learn how PyScript's <py-env> tag lets you declare Python package dependencies directly in HTML, letting micropip fetch and install them automatically.
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.
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.
Need to display a CSV in the browser without a backend? PyScript’s bundled Pandas stack lets you fetch, parse, and render a DataFrame as an interactive HTML table—all client‑side. Learn how to do it, the performance trade‑offs, and best‑practice tips.
