![]() Third party packages are imported through the new HTML tag. However, by switching to the dev version of Pyodide, we can access packages that will be available in upcoming releases, found in the main branch. Note that opencv-python, the package we need for OpenCV functionality, is not in the list. You can view the list for the current release, v0.20.0, under the version tag on GitHub. There are several packages available for out-of-the-box import through Pyodide. We can do so by including the following configuration in the section of our HTML: As of the time of writing, we must use the development branch of Pyodide to successfully import OpenCV into our application. We can also configure PyScript setup options within a new tag. To include the PyScript code and styles, add the following to the section of your HTML file: ![]() Setting up a PyScript app is as simple as creating an HTML file, importing JS and CSS files, and including Python code within a HTML tag. In this post, I will walk us through setting up a PyScript application, and adding Python-based computer vision ( OpenCV) functionality to a web map, all running within the browser. ![]() However, enabling Python developers to quickly create frontend applications with minimal friction is a powerful concept. JavaScript (JS) will surely remain the dominant language in browsers for the foreseeable future. PyScript, along with WebAssembly and Pyodide, enables us to run Python directly in the browser, without the explicit need for our own APIs or servers. Prototyping and Python are big parts of what I do at Sparkgeo, so when PyScript was announced at P圜on US 2022, I was all ears.
