How to add static(html, css, js, etc) files in pyinstaller to create standalone exe file?

Question

I\'m using QtWebEngineWidgets, QtWebChannel to create PyQt5 application, which uses HTML, CSS, JavaScript.

It\'s working fine, when we run in

Answer 1

From your question you can presume that the structure of your project is as follows:

├── index.html
├── jquery.js
├── main.py
├── my_custom.js
└── styles.css

For your case there are 2 options:

1. using --add-data

   import os
   import sys
   
   from PyQt5 import QtCore, QtWidgets, QtWebEngineWidgets
   
   
   def resource_path(relative_path):
       """ Get absolute path to resource, works for dev and for PyInstaller """
       try:
           # PyInstaller creates a temp folder and stores path in _MEIPASS
           base_path = sys._MEIPASS
       except Exception:
           base_path = os.path.abspath(".")
   
       return os.path.join(base_path, relative_path)
   
   
   if __name__ == "__main__":
       import sys
   
       app = QtWidgets.QApplication(sys.argv)
       view = QtWebEngineWidgets.QWebEngineView()
   
       filename = resource_path("index.html")
       url = QtCore.QUrl.fromLocalFile(filename)
   
       view.load(url)
       view.show()
       sys.exit(app.exec_())
   

   If you want to add external resources to the executable then you must use the "--add-data" option:

   pyinstaller --onefile --windowed --add-data="index.html:." --add-data="jquery.js:." --add-data="my_custom.js:." --add-data="styles.css:." main.py
   

   For windows change ":" with ";".

2. using .qrc

   With this method you will convert the files (.html, .css, .js, etc) into .py code using pyrcc5 for this you must follow the following steps:

   2.1. Create a file called resource.qrc with the following content in the project folder:

   <RCC>
       <qresource prefix="/">
           <file>index.html</file>
           <file>jquery.js</file>
           <file>my_custom.js</file>
           <file>styles.css</file>
       </qresource>
   </RCC>
   

   2.2 Convert it to .py using pyrcc5:

   pyrcc5 resource.qrc -o resource_rc.py
   

   2.3 Import the resource_rc.py file and use the url with schema "qrc" in the main.py file:

   import os
   import sys
   
   from PyQt5 import QtCore, QtWidgets, QtWebEngineWidgets
   
   import resource_rc
   
   
   if __name__ == "__main__":
       import sys
   
       app = QtWidgets.QApplication(sys.argv)
       view = QtWebEngineWidgets.QWebEngineView()
   
       url = QtCore.QUrl("qrc:/index.html")
   
       view.load(url)
       view.show()
       sys.exit(app.exec_())
   

   2.4 Compile the project using your initial command

   pyinstaller --onefile --windowed main.py
