+# WebApp
+
+Run any website as standalone desktop application
+
+[master](https://github.com/MarcinOrlowski/website-as-app/tree/master) branch:
+[![Code lint](https://github.com/MarcinOrlowski/website-as-app/actions/workflows/linter.yml/badge.svg?branch=master)](https://github.com/MarcinOrlowski/website-as-app/actions/workflows/linter.yml)
+[![MD Lint](https://github.com/MarcinOrlowski/website-as-app/actions/workflows/markdown.yml/badge.svg?branch=master)](https://github.com/MarcinOrlowski/website-as-app/actions/workflows/markdown.yml)
+---
+
+Small Python script opening any web page in dedicated window, using embedded QT WebEngine. There are
+no visible browser's UI etc., so the that can be useful to turn any website into standalone desktop
+application. This is useful if you, as me, would like to have a website run as standalone app,
+independently of your main browser which can be beneficial as it gives you separate entry in
+window manager or task switcher etc.
+
+> **IMPORTANT:** This tool is **NOT** turning websites into OFFLINE apps! It's about separating
+> each of your key websites i.e. from each other, or gazzilions of your browser's tabs. But you
+> still MUST be connected to the Internet for the apps (websites) to work as previously.
+
+## Installation
+
+Use `pip` to install the script system-wide:
+
+```bash
+$ pip install website-as-app
+```
+
+If you want to use virtual environment (which is recommended):
+
+```bash
+$ python -m venv venv
+$ source venv/bin/activate
+$ pip install website-as-app
+```  
+
+Once app is running, please use `--help` to see all available options, as i.e. custom icon,
+window title etc.
+
+## Usage
+
+When app is installed system-wide, you can run it from anywhere:
+
+```bash
+$ webapp "https://github.com"
+```
+
+If you are using virtual environment, there's handy Bash script in [extras/](extras/) directory 
+which takes care of initializing virtual environment and running the app using that environment.
+You simply use `extras/webapp.sh` script instead of `webapp` directly:
+
+```bash
+$ extras/webapp.sh "https://github.com"
+```
+
+### Configuration
+
+Available options:
+
+```bash
+webapp -h
+usage: webapp [--profile PROFILE] [--name NAME] [--icon ICON] [--zoom ZOOM] [--no-tray] url
+
+Open any website in standalone window (like it's an app)
+
+positional arguments:
+url                   The URL to open
+
+options:
+--profile PROFILE     Profile name (for cookies isolation etc). Default: "default"
+--name NAME, -n NAME  Application name (shown as window title)
+--geometry GEOMETRY   Initial window geometry (in format "WIDTHxHEIGHT+X+Y")
+--icon ICON, -i ICON  Full path to image file to be used as app icon
+--zoom ZOOM, -z ZOOM  Initial WebBrowserView zoom factor. Default: 1.0
+--no-tray             Disables system tray support (closing window terminates app)
+```
+
+The most important option is `--profile` which allows you to isolate cookies and app settings
+per instance. Any instance using the same profile will have access to the same cookies and
+settings. This is useful if you want to run multiple instances of the same app, but with
+different accounts. By default `default` profile is used and it's recommended to use different
+profile per each app instance.
+
+## Current limitations
+
+* Due to security based limitations of embedded `QWebBrowerView` you will not be able
+  to save any file to your local storage nor filesystem.
+* Website's Javascript code cannot write to system clipboard so you might need to manually
+  select given portion of the site and copy using function from context menu as any buttons
+  on the page that is using JS to write to the host's clipboard will not currently work.

+1. [Profiles](#profiles)
+2. [Building the package](#building-the-package)
+
+---
+
+## Profiles
+
+Each instance can be separated from others by using dedicated "profile". Any
+instance using the same profile, will have access to the same shared data like
+cookies or app settings.
+
+### Location
+
+If for any reason you would like to reset the profile, you can do it by removing the profile
+directory:
+
+Windows
+
+  ```
+  %USERPROFILE%\AppData\Local\MarcinOrlowski\WebsiteAsApp\<APP_PROFILE_NAME>\
+  ```
+
+Linux
+
+  ```
+  ~/.local/share/MarcinOrlowski/WebsiteAsApp/<APP_PROFILE_NAME>/
+  ```
+
+MacOS
+
+  ```
+  ??? (PLEASE ASSIST)
+  ```
+
+---
+
+## Building the package
+
+1. Checkout the source code:
+
+```bash
+$ cd <DIR>
+$ git clone ....
+$ cd website-as-app
+```
+
+2. Setup its runtime environment (NOTE: if you are using different shell than `bash` (i.e. `fish`),
+   please use correct `activate` script from `venv/bin/` directory):
+
+```bash
+$ python -m venv venv
+$ source venv/bin/activate  # User right one for your shell
+```
+
+3. Install all the dependencies:
+
+```bash
+(venv) $ pip install -r requirements-dev.txt
+```
+
+4. Build the package:
+
+```bash
+(venv) $ python -m build
+```
+
+5. Install package locally for testing.
+   We intentionally ignore `install --upgrade` while planting new build, as we need to ensure no
+   cached bytecode from previous version remains (which could be the case as we do not increment the
+   version each build).
+
+```bash
+(venv) $ pip uninstall --yes dist/website_as_app-1.0.0-py3-none-any.whl
+(venv) $ pip install dist/website_as_app-1.0.0-py3-none-any.whl
+```
+
+6. Test the app
+
+```bash
+(venv) $ webapp -h
+usage: webapp [-h] [--name TITLE] [--icon ICON] [--profile PROFILE] [--zoom ZOOM] url
+...
+```
