Overview

https://pywebview.flowrl.com

pywebview is a lightweight cross-platform wrapper around a webview component that allows to display HTML content in its own native GUI window. It gives you power of web technologies in your desktop application, hiding the fact that GUI is browser based. You can use pywebview either with a lightweight web framework like Flask or Bottle or on its own with a two way bridge between Python and DOM.

pywebview uses native GUI for creating a web component window: WinForms on Windows, Cocoa on macOS and QT or GTK on Linux. If you choose to freeze your application, pywebview does not bundle a heavy GUI toolkit or web renderer with it keeping the executable size small. pywebview is compatible with Python 3.

pywebview is created by Roman Sirokov.

Getting started

Install

pip install pywebview

On Linux you need additional libraries. Refer to the installation page for details.

Hello world

import webview
webview.create_window('Hello world', 'https://pywebview.flowrl.com/hello')
webview.start()

Explore pywebview further by reading documentation, examples or contributing. If React is your thing, get started right away with React boilerplate.

Upgrading to WebKit2 (GTK) and WKWebView (Cocoa)
Specification

Platform: Fedora

Version: 27

Description

I was wondering if you are going to move to WebKit2 and deprecate WebKit1. I've been trying to develop a Python/Gtk application and keep seeing warnings about WebKit security. Such as; https://blogs.gnome.org/mcatanzaro/2016/02/01/on-webkit-security-updates/

In my application I'm using a try/except to test the version like this; ` import gi try: gi.require_version('Gtk', '3.0') from gi.repository import Gtk, Gdk # , Gio except: sys.exit("This script requires Gtk 3.0 or newer!")

try: gi.require_version('WebKit2', '4.0') from gi.repository import WebKit2 except: sys.exit("This script requires WebKit2 4.0 or newer!") ` As a side note, I'm having a difficult time learning how to use WebKit. Searching for answers is what led me to pywebview. Also, I tried to find a way to label this as label:"help wanted", but I can't see how to apply a label, sorry.

[Windows 10] Window height properties not computing in exe
Specification

pywebview version: 3.0

platform / version: Windows 10

Description

I got packaging to work for my React app on Mac and Windows. The only weird thing is on windows when I run the exe the height in the page seems to be missing, this is best explained through the photos. It works fine if i run my code In pycharms, it's only after packaging as exe do I see this weird bug.

Run from PyCharm on windows and what it looks like on mac: https://i.imgur.com/sJZCegr.png After packaging: https://i.imgur.com/6kEUfTT.png

To recreate this, you can make a new react app with npx create-react-app, run npm build in it, and move the index.html from the build folder to a templates folder and the rest to the static folder.

And I use this command to package pyinstaller -w -F --add-data "templates;templates" --add-data "static;static" --add-data "WebBrowserInterop.x86.dll;./" --onefile -y flair.py

It's also weird that its using x86 since I'm pretty sure I have the 64 bit of python. And also when I used the full path like C:\Users\saran\AppData\Local\Programs\Python\Python37-32\Lib\site-packages\webview\lib\WebBrowserInterop.x86.dll It never worked for me. Only when I copied it into local folder did it work.

Provide JavaScript ↔ Python bridge to pywebview

It's possible to create a bridge between the webview and python without depending on sockets. The problem of starting a server on windows is that the firewall can block the application or show a security warning, including when I start the server only on localhost. http://stackoverflow.com/questions/40492842/how-to-suppress-the-windows-security-alert-for-windows-firewall

Very probably this bridge between a webview and the python interpreter is much more efficient because it doesnt use the HTTP protocol, and it hasn't the before mentioned problem:

Support for multiple windows?

This feature will probably change the API significantly, but I wanted to at least document the need.

Essentially my idea would be that the webview.create_window() function returns a window handle or maybe even a BrowserView object that can be manipulated directly. That way you could instantiate multiple windows and destroy them individually.

Perhaps the app can quit when the last window is destroyed, or maybe there could be a 'master' window instance that can control all the other ones.

I'm kind of spit-balling but hopefully you get the idea. Could pywebview support multiple windows? Can you think of some other way to do it that doesn't involve a major API change?

Question: Linking html resources

What is the correct way to link local js and ccs files? It appears the standard html and do not work. I also tried using the full path for both and that didn't work either. And I tried ./style.css. that didn't work.

It does look like CDN links work but they take a long time to load.

Any advice?

pyInstaller to freeze the app

Hi,

I tried several things, and even py2Exe on windows, but nothing worked. As I am using python 3.5, I figured out pyInstaller would be ok, but still when I compile with it I get an exe that doesn't work, and a bunch of missing libraries warnings.

Is there any working example of how to compile the simple pywebview introduction example (just a window that loads a website) for pyInstaller? Or if someone can share it (the exact call, with the exact params, and the spec file, if needed).

Thanks,

(Note: I did try the example with the py2Exe, but didn't work).

Memory leak on windows
There appears to be a memory leak on Windows, occurring whenever webview.evaluate_js() is called. I'm using pywebview v1.7 + "pythonnet" on Windows 10 64bit, with python3.6.2. The same issue does not exist on mac.

Code to reproduce (most trivial example I could come up with)

import webview import threading import time threadStopSignal = threading.Event() threadStopSignal.clear() def checkOnDOM(): global threadStopSignal while threadStopSignal.is_set() == False: time.sleep(.01) webview.evaluate_js("doNothing()" ) def main(): print("Beginning program") t = threading.Thread(target=checkOnDOM) t.start() webview.create_window("This is a window", "index.html") threadStopSignal.set() t.join(3.0) main()

<!DOCTYPE html> <html> <script type="text/javascript"> function doNothing() { } </script> <head> </head> <body> <div> </div> </body> </html>

Then watch the memory usage of the program grow in the task manager. The memory usage on Mac remains static when running this program.

In order to further investigate, I later changed doNothing to

function doNothing() { return document.getElementsByTagName("script").length; }

which, when printed in python, made it clear that the number of script elements is growing (and never shrinking) with each call to evaluate_js(). Not sure if that's the expected behavior.

Finally, if the value of those script tags is printed, we see something like function invokecb2c8066aea211e7849010f0050b27cc() {return eval("doNothing()")} which over time monotonically grows to higher values

function invokef9d07746aea211e780ee10f0050b27cc() {return eval("doNothing()")} function invokef9d29312aea211e791b410f0050b27cc() {return eval("doNothing()")} function invokef9d46ef6aea211e78f1f10f0050b27cc() {return eval("doNothing()")}

up and up.... Are these pointers to resources in windows that never get cleaned up, or are they just GUIDs?

Happy to provide any more info.

Really enjoying the library, btw! Hoping to resolve the memory issue on the windows side so I can use it further.

cef hangs while resizing in certain conditions

Specification

pywebview version: 3.2
platform / version: Win7 Pro SP1
cefpython3 version 66.0

Description

Observed reproducible hang during use of cef gui, if triggering some kind of update while resizing the window. Minimally this code usually (but not 100% of the time) hangs on my machine:

import webview
window=webview.create_window('Hello world', html='<h1>hello</h1>')
def reload_and_resize():
    window.evaluate_js("location.reload()")
    window.resize(1000, 420)
webview.start(reload_and_resize, gui="cef")

or while manually resizing something more like this:

import webview,time
window=webview.create_window('Hello world', html='<h1>hello</h1>')
def keep_reloading():
    while True:
        time.sleep(1)
        window.evaluate_js("location.reload()")
webview.start(keep_reloading, gui="cef")

This may be a cefpython issue.

JS API drops invocations due to potential bug/race condition on GTK platform
Specification

pywebview version: 3.7.2

operating system: Ubuntu 22.04

web renderer: GTK webengine

Description

When using GTK platform, there appears to be a bug in how it invokes functions via the JS -> Py API mechanism. Namely, if you call two JS_API function in quick succession, one or more of them will never return and will not be invoked on the Python side.

Here's a minimal example that demonstrates the problem:

import webview html = """ <!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> </head> <body> <h1>JS API Example</h1> <p id='pywebview-status'><i>pywebview</i> is not ready</p> <div id="response-container"></div> <script> window.addEventListener('pywebviewready', function() { var container = document.getElementById('pywebview-status') container.innerHTML = '<i>pywebview</i> is ready' doTheThings() }) function doTheThings() { var container = document.getElementById('response-container') pywebview.api.do_thing_1().then(function(response) { container.innerHTML += '<p>' + response + '</p>' }) pywebview.api.do_thing_2().then(function(response) { container.innerHTML += '<p>' + response + '</p>' }) pywebview.api.do_thing_3().then(function(response) { container.innerHTML += '<p>' + response + '</p>' }) } </script> </body> </html> """ class Api: def do_thing_1(self): return "Done thing 1" def do_thing_2(self): return "Done thing 2" def do_thing_3(self): return "Done thing 3" if __name__ == '__main__': api = Api() window = webview.create_window('API example', html=html, js_api=api) webview.start(gui="gtk", debug=True)

Executing this with the GTK platform, I consistently only ever get the "Done thing 3" message. It works as-expected on, at least, the Cocoa & QT backends.

Looking at the code, the issue appears to be with how the document title is used as a transport mechanism for invoking the JS API. My assumption of what is happening is that if document.title is set twice by pywebview._bridge.call before GTK's on_title_change is run, then only the last call to set the title will get invoked.

Assuming that's the issue, a potential fix might be to have to pywebview._bridge.call wait until the python is done reading webview.get_title before it changes the title again. Perhaps the python code calls webview.run_javascript('document.title=""') after webview.get_title(), which JS takes as a notification that it can invoke another function. Or something to that effect.

Practicalities

YES I am willing to work on this issue myself. I can make a PR. Mostly I'd like validation on the problem and suggested fix before proceeding.

NO I am not prepared to support this issue financially.

Non blocking window

Is there the possibility to open a window in non-blocking mode? I see there was an example in an older branch, which is not working with the current release. E.g. removing "Thread.Join()" in the winforms.py would do that, but thats probably considered as a quick&dirty hack?

Support for WSGI

Encapsulated server in an object so new ones could be added easily. Each window with a local URL or app gets its own server, plus one global server so serverless windows can use the JS API.

Passes tests on a Mac, and runs a non-trivial FastAPI app converted to WSGI with a2wsgi.
