Build pywebview apps easily
Project description
webexe
Turn your HTML + Python project into a desktop application.
webexe uses pywebview to combine a web frontend with a Python backend, then optionally packages it into a Windows executable.
Features
- Use HTML / CSS / JavaScript as your UI
- Use Python as your backend
- Expose selected Python APIs to JavaScript
- Development mode with debugging support
- Build standalone executable with PyInstaller
How it works
HTML / JS
|
v
pywebview
|
v
Python API
|
v
Windows EXE
Only functions exposed through api are available to the frontend.
Example:
# back.py
def hello():
return "Hello from Python"
api = {
"hello": hello
}
Frontend:
const result = await window.pywebview.api.hello();
console.log(result);
Installation
pip install webexe
Create a project
Your project should contain:
myapp/
│
├─ index.html
├─ back.py
└─ build.py
Development
Run:
python build.py --dev
Development mode:
- Runs directly without packaging
- Opens pywebview debug tools
- Faster for testing
Build
Create executable:
python build.py
Output:
dist/
└─ MyApp.exe
Example
index.html
<!doctype html>
<html>
<body>
<h1>Hello webexe</h1>
<button onclick="test()">
Call Python
</button>
<script>
async function test() {
const result =
await window.pywebview.api.hello();
alert(result);
}
</script>
</body>
</html>
back.py
def hello():
return "Hello from Python"
api = {
"hello": hello
}
Why webexe?
Electron is powerful, but sometimes you only need:
- A lightweight desktop shell
- A web UI
- Python automation/backend
webexe provides a simpler bridge between web technologies and Python.
Roadmap
-
webexe initproject generator - Custom application name
- Better error messages
- More build options
