# PyScript # PyScript
## PyScript is an open source platform for Python in the browser. ## What is PyScript
Using PyScript is as simple as: ### Summary
PyScript is a framework that allows users to create rich Python applications in the browser using HTML's interface and the power of [Pyodide](https://pyodide.org/en/stable/), [WASM](https://webassembly.org/), and modern web technologies.
To get started see the [getting started tutorial](docs/tutorials/getting-started.md).
For examples see [here](examples).
### Longer Version
PyScript is a meta project that aims to combine multiple open technologies into a framework that allows users to create sophisticated browser applications with Python. It integrates seamlessly with the way the DOM works in the browser and allows users to add Python logic in a way that feels natural both to web and Python developers.
## Try PyScript
To try PyScript, import the appropriate pyscript files into the `<head>` tag of your html page with:
```html ```html
<!doctype html> <head>
<html lang="en"> <link rel="stylesheet" href="https://pyscript.net/latest/pyscript.css" />
<head> <script defer src="https://pyscript.net/latest/pyscript.js"></script>
<meta charset="utf-8" /> </head>
<meta name="viewport" content="width=device-width,initial-scale=1" />
<title>PyScript!</title>
<link
rel="stylesheet"
href="https://pyscript.net/releases/2025.11.2/core.css"
/>
<script
type="module"
src="https://pyscript.net/releases/2025.11.2/core.js"
></script>
</head>
<body>
<!-- type mpy (MicroPython) or py (Pyodide) to run some Python -->
<script type="mpy" terminal>
print("Hello, world!")
</script>
</body>
</html>
``` ```
PyScript enables the creation of rich Python applications in the browser using You can then use PyScript components in your html page. PyScript currently implements the following elements:
[Pyodide](https://pyodide.org/en/stable/) (a version of
[CPython](https://python.org/)), [MicroPython](https://micropython.org/),
[WASM](https://webassembly.org/), and modern web technologies. It means Python
now runs anywhere a browser runs: desktop, laptop, mobile, tablet, or any other
browser enabled device.
To start building, read the - `<py-script>`: can be used to define python code that is executable within the web page. The element itself is not rendered to the page and is only used to add logic
[Beginning PyScript tutorial](https://docs.pyscript.net/latest/beginning-pyscript/). - `<py-repl>`: creates a REPL component that is rendered to the page as a code editor and allows users to write executable code
For example applications, see [here](https://pyscript.com/@examples). Check out the [the examples directory](examples) folder for more examples on how to use it, all you need to do is open them in Chrome.

# Troubleshooting
This page is meant for troubleshooting common problems with PyScript.
## Table of contents:
- [Make Setup](#make-setup)
## Make setup
A lot of problems related to `make setup` are related to node and npm being outdated. Once npm and node are updated, `make setup` should work. You can follow the steps on the [npm documentation](https://docs.npmjs.com/try-the-latest-stable-version-of-npm) to update npm (the update command for Linux should work for Mac as well). Once npm has been updated you can continue to the instructions to update node below.
To update Node run the following commands in order (Most likely you'll be prompted for your user password, this is normal):
```
sudo npm cache clean -f
sudo npm install -g n
sudo n stable
```

# @pyscript/bridge
Import Python utilities directly in JS
```js
// main thread
const { ffi: { func_a, func_b } } = await import('./test.js');
// test.js
import bridge from 'https://esm.run/@pyscript/bridge';
export const ffi = bridge(import.meta.url, { type: 'mpy', worker: false });
// test.py
def func_a(value):
print(f"hello {value}")
def func_b():
import sys
return sys.version
```
### Options
* **pyscript**: the release version to automatically import if not already available on the page. If no version is provided the *developers' channel* version will be used instead (for developers' purposes only).
* **type**: `py` by default to bootstrap *Pyodide*.
* **worker**: `true` by default to bootstrap in a *Web Worker*.
* **config**: either a *string* or a PyScript compatible config *JS literal* to make it possible to bootstrap files and whatnot. If specified, the `worker` becomes implicitly `true` to avoid multiple configs conflicting on the main thread.
* **env**: to share the same environment across multiple modules loaded at different times.
## Tests
Run `npx mini-coi .` within this folder to then reach out `http://localhost:8080/test/` that will show:
```
PyScript Bridge
------------------
no config
```
The [test.js](./test/test.js) files uses the following defaults:
* `pyscript` as `"2025.8.1"`
* `type` as `"mpy"`
* `worker` as `false`
* `config` as `undefined`
* `env` as `undefined`
To test any variant use query string parameters so that `?type=py` will use `py` instead, `worker` will use a worker and `config` will use a basic *config* that brings in another file from the same folder which exposes the version.
To recap: `http://localhost:8080/test/?type=py&worker&config` will show this instead:
```
PyScript Bridge
------------------
3.12.7 (main, May 15 2025, 18:47:24) ...
```
Please note when a *config* is used, the `worker` attribute is always `true`.

# @pyscript/core
PyScript brings two Python interpreters to the browser:
- [MicroPython](https://micropython.org/) - a lean and efficient implementation
of the Python 3 programming language that includes a small subset of the
Python standard library and is optimised to run on microcontrollers and in
constrained environments (like the browser).
- [Pyodide](https://pyodide.org)) - a port of all CPython to WebAssembly.
These interpreters are compiled to [WebAssembly](https://webassembly.org/)
(shortened to WASM). The browser provides a secure WASM computing sandbox. Both
interpreters are compiled to web assembly with
[Emscripten](https://emscripten.org/). PyScript core maintainers work closely
with the core maintainers of both MicroPython and Pyodide (and CPython). We
work hard to ensure PyScript works efficiently in browsers on all platforms:
desktop, mobile, or elsewhere.
Our technical documentation for using this project can be
[found here](https://docs.pyscript.net/).
PyScript sits on two further projects (both written in JavaScript):
1. [polyscript](https://github.com/pyscript/polyscript/#readme) - used to
bootstrap WASM compiled interpreters in a browser.
2. [coincident](https://github.com/WebReflection/coincident) - used to simplify
worker based tasks.
PyScript itself is mostly written in JavaScript. The test suite for JavaScript
is in two parts: automated tests run in [playwright](https://playwright.dev/),
and manual tests you have to run in a browser and check yourself. PyScript also
has a plugin system so third parties can extend its capabilities with
JavaScript. Our built-in core plugins can be found in the `src/plugins`
directory. We describe how to write third party plugins in our
[developer documentation](https://docs.pyscript.net/latest/user-guide/plugins/).
We provide a `pyscript` namespace containing Python modules for common browser
based APIs and features (i.e. you can `import pyscript` in Python code running
inside PyScript, to access these features). The Python code for the `pyscript`
namespace is in `src/stdlib/pyscript` with the associated test suite in
`tests/python`. The tests use the browser friendly
[uPyTest](https://github.com/ntoll/upytest) test framework for checking Python
code running _within_ PyScript. All the Python tests are run in each each
available interpreter in both the main thread and a web worker (i.e. the
test suite is run four times, accounting for each combination of interpreter
and main/worker context).
When you create a local build all the automated tests (JavaScript and Python)
are run.
## Developer Guide
Full instructions for setting up a working development environment, how to
build PyScript and how to test it can be
[found in our official docs](https://docs.pyscript.net/latest/developers/).
The short version is:
- Ensure you have Python, node and npm installed.
- Create a Python virtual environment.
- In the root of this repository `make setup`.
- `make build` to build PyScript.
- As dependencies change over time, `make update` to keep in sync.
To start using the locally built version of PyScript, you'll need an HTML
page something like this (note the relative paths to assets in the `dist`
directory, in the `<head>` of the document):
```html
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Pure Python PyScript tests</title>
<link rel="stylesheet" href="../../dist/core.css" />
<script type="module" src="../../dist/core.js"></script>
</head>
<body>
<script type="mpy" src="./main.py" config="./conf.toml"></script>
</body>
</html>
```
Once set up, you should be able to run the most common activities via the
`make` command:
```
$ make
There is no default Makefile target right now. Try:
make setup - check your environment and install the dependencies.
make update - update dependencies.
make clean - clean up auto-generated assets.
make build - build PyScript.
make precommit-check - run the precommit checks (run eslint).
make test - run all automated tests in playwright.
make fmt - format the code.
make fmt-check - check the code formatting.
```
## Artifacts
There are two main artifacts in this project:
- **stdlib** and its content: `src/stdlib/pyscript.js` exposes, as a
JavaScript object literal, all the _Python_ content within the folder
(recursively).
- **plugins** and its content: `src/plugins.js` exposes all available
_dynamic imports_, and is able to instrument the bundler to create files
apart from the `_dist/_` folder, so that by default _core_ remains as small
as possible.
Accordingly, whenever a file contains this warning at its first line, **please
do not change such file directly before submitting a merge request**, as that
file will be overwritten at the next `npm run build` command, either here or
in _CI_:
```js
// ⚠️ This file is an artifact: DO NOT MODIFY
```
## Plugins
While community or third party plugins don't need to be part of this repository
and can be added just importing `@pyscript/core` as module, there are a few
plugins that we would like to make available by default and these are
considered _core plugins_.
To add a _core plugin_ to this project define the plugin entry-point and name
in the `src/plugins` folder (see the `error.js` example) and create, if
necessary, a folder with the same name where extra files or dependencies can be
added.
The _build_ command will include plugins by name as artifacts so that the
bundler can create ad-hoc files within the `dist/` folder.
## Python
The `pyscript` package available in _Python_ lives in the folder
`src/stdlib/pyscript/`.
All _Python_ files will be embedded automatically whenever `npm run build`
happens and reflected into the `src/stdlib/pyscript.js` file.
Its _core_ responsibility is to ensure those files will be available through
the filesystem in either the _main_ thread, or any _worker_.
## Release
To cut a new release of PyScript simply
[add a new release](https://github.com/pyscript/pyscript/releases) while
remembering to write a comprehensive changelog. A
[GitHub action](https://github.com/pyscript/pyscript/blob/main/.github/workflows/publish-release.yml)
will kick in and ensure the release is described and deployed to a URL with the
pattern: https://pyscript.net/releases/YYYY.M.v/ (year/month/version - as per
our [CalVer](https://calver.org/) versioning scheme).
Then, the following three separate repositories need updating:
- [Documentation](https://github.com/pyscript/docs) - Change the `version.json`
file in the root of the directory and then `node version-update.js`.
- [Homepage](https://github.com/pyscript/pyscript.net) - Ensure the version
referenced in `index.html` is the latest version.
- [PSDC](https://pyscript.com) - Use discord or Anaconda Slack (if you work at
Anaconda) to let the PSDC team know there's a new version, so they can update
their project templates.

# PyScript 3rd Party
This folder contains artifacts created via [3rd-party.cjs](../../rollup/3rd-party.cjs).
As we would like to offer a way to run PyScript offline, and we already offer a `dist` folder with all the necessary scripts, we have created a foreign dependencies resolver that allow to lazy-load CDN dependencies out of the box.
Please **note** these dependencies are **not interpreters**, because interpreters have their own mechanism, folders structure, WASM files, and whatnot, to work locally, but at least XTerm or the TOML parser, among other lazy dependencies, should be available within the dist folder.
## Licenses
All licenses provided by 3rd-party authors can be found in [3rd-party-licenses](../3rd-party-licenses/) folder.

"""
This is the main `pyscript` namespace. It provides the primary Pythonic API
for users to interact with the
[browser's own API](https://developer.mozilla.org/en-US/docs/Web/API). It
includes utilities for common activities such as displaying content, handling
events, fetching resources, managing local storage, and coordinating with
web workers.
The most important names provided by this namespace can be directly imported
from `pyscript`, for example:
```python
from pyscript import display, HTML, fetch, when, storage, WebSocket
```
The following names are available in the `pyscript` namespace:
- `RUNNING_IN_WORKER`: Boolean indicating if the code is running in a Web
Worker.
- `PyWorker`: Class for creating Web Workers running Python code.
- `config`: Configuration object for pyscript settings.
- `current_target`: The element in the DOM that is the current target for
output.
- `document`: The standard `document` object, proxied in workers.
- `window`: The standard `window` object, proxied in workers.
- `js_import`: Function to dynamically import JS modules.
- `js_modules`: Object containing JS modules available to Python.
- `sync`: Utility for synchronizing between worker and main thread.
- `display`: Function to render Python objects in the web page.
- `HTML`: Helper class to create HTML content for display.
- `fetch`: Function to perform HTTP requests.
- `Storage`: Class representing browser storage (local/session).
- `storage`: Object to interact with browser's local storage.
- `WebSocket`: Class to create and manage WebSocket connections.
- `when`: Function to register event handlers on DOM elements.
- `Event`: Class representing user defined or DOM events.
- `py_import`: Function to lazily import Pyodide related Python modules.
If running in the main thread, the following additional names are available:
- `create_named_worker`: Function to create a named Web Worker.
- `workers`: Object to manage and interact with existing Web Workers.
All of these names are defined in the various submodules of `pyscript` and
are imported and re-exported here for convenience. Please refer to the
respective submodule documentation for more details on each component.
!!! Note
Some notes about the naming conventions and the relationship between
various similar-but-different names found within this code base.
```python
import pyscript
```
The `pyscript` package contains the main user-facing API offered by
PyScript. All the names which are supposed be used by end users should
be made available in `pyscript/__init__.py` (i.e., this source file).
```python
import _pyscript
```
The `_pyscript` module is an internal API implemented in JS. **End users
should not use it directly**. For its implementation, grep for
`interpreter.registerJsModule("_pyscript",...)` in `core.js`.
```python
import js
```
The `js` object is
[the JS `globalThis`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/globalThis),
as exported by Pyodide and/or Micropython's foreign function interface
(FFI). As such, it contains different things in the main thread or in a
worker, as defined by web standards.
```python
import pyscript.context
```
The `context` submodule abstracts away some of the differences between
the main thread and a worker. Its most important features are made
available in the root `pyscript` namespace. All other functionality is
mostly for internal PyScript use or advanced users. In particular, it
defines `window` and `document` in such a way that these names work in
both cases: in the main thread, they are the "real" objects, in a worker
they are proxies which work thanks to
[coincident](https://github.com/WebReflection/coincident).
```python
from pyscript import window, document
```
These are just the `window` and `document` objects as defined by
`pyscript.context`. This is the blessed way to access them from `pyscript`,
as it works transparently in both the main thread and worker cases.

"""
Execution context management for PyScript.
This module handles the differences between running in the
[main browser thread](https://developer.mozilla.org/en-US/docs/Glossary/Main_thread)
versus running in a
[Web Worker](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Using_web_workers),
providing a consistent API regardless of the execution context.
Key features:
- Detects whether code is running in a worker or main thread. Read this via
the boolean `pyscript.context.RUNNING_IN_WORKER`.
- Parses and normalizes configuration from `polyscript.config` and adds the
Python interpreter type via the `type` key in `pyscript.context.config`.
- Provides appropriate implementations of `window`, `document`, and `sync`.
- Sets up JavaScript module import system, including a lazy `js_import`
function.
- Manages `PyWorker` creation.
- Provides access to the current display target via
`pyscript.context.display_target`.
!!! warning
These are key differences between the main thread and worker contexts:
Main thread context:
- `window` and `document` are available directly.
- `PyWorker` can be created to spawn worker threads.
- `sync` is not available (raises `NotSupported`).
Worker context:
- `window` and `document` are proxied from main thread (if SharedArrayBuffer
available).
- `PyWorker` is not available (raises `NotSupported`).
- `sync` utilities are available for main thread communication.

This module provides the `display()` function for rendering Python objects
in the web page. The function introspects objects to determine the appropriate
[MIME type](https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/MIME_types/Common_types)
and rendering method.
Supported MIME types:
- `text/plain`: Plain text (HTML-escaped)
- `text/html`: HTML content
- `image/png`: PNG images as data URLs
- `image/jpeg`: JPEG images as data URLs
- `image/svg+xml`: SVG graphics
- `application/json`: JSON data
- `application/javascript`: JavaScript code (discouraged)
The `display()` function uses standard Python representation methods
(`_repr_html_`, `_repr_png_`, etc.) to determine how to render objects.
Objects can provide a `_repr_mimebundle_` method to specify preferred formats
like this:
```python
def _repr_mimebundle_(self):
return {
"text/html": "<b>Bold HTML</b>",
"image/png": "<base64-encoded-png-data>",
}
```
Heavily inspired by
[IPython's rich display system](https://ipython.readthedocs.io/en/stable/api/generated/IPython.display.html).

This module is a Python implementation of the

Standard JSON cannot handle circular references - attempting to serialize an
object that references itself will cause an error. Flatted solves this by
transforming circular structures into a flat array format that can be safely
serialized and later reconstructed.
Common use cases:
- Serializing complex object graphs with circular references.
- Working with DOM-like structures that contain parent/child references.
- Preserving object identity when serializing data structures.
```python
