 13 | 
 14 | ## Setting Up Development Environment
 15 | 
 16 | ### Environment variables
 17 | 
 18 | All environment variables are stored in `.env`.
 19 | This is where we store sensitive information that we do not want to include in the source code, such as database login information.
 20 | 
 21 | 1. Create a copy of `.env.example` and rename it as `.env`.
 22 | 
 23 | 2. Fill in the missing information, such as database login username and password.
 24 | 
 25 | To access variables defined in `.env`, package `python-dotenv` is used.
 26 | 
 27 | ```py
 28 | from dotenv import load_dotenv
 29 | 
 30 | load_dotenv()
 31 | ```
 32 | 
 33 | Access ENVIRONMENT variable for example
 34 | 
 35 | ```py
 36 | ENVIRONMENT = os.environ['ENVIRONMENT']
 37 | ```
 38 | 
 39 | ### React GUI
 40 | 
 41 | 1. Install yarn
 42 | <https://classic.yarnpkg.com/en/docs/install/#windows-stable>
 43 | 
 44 | 2. Install node dependencies
 45 | 
 46 |     ```sh
 47 |     yarn
 48 |     ```
 49 | 
 50 | 3. Run react app
 51 | 
 52 |     ```bash
 53 |     yarn start
 54 |     ```
 55 | 
 56 | ### PyQt Web Server
 57 | 
 58 | 1. Install virtualenv
 59 | 
 60 |     ```bash
 61 |     pip install virtualenv
 62 |     ```
 63 | 
 64 | 2. Create virtualenv
 65 | 
 66 |     ```bash
 67 |     python -m venv ./venv
 68 |     ```
 69 | 
 70 | 3. Activate virtualenv
 71 | 
 72 |     ```bash
 73 |     # win
 74 |     venv/Scripts/activate.bat
 75 | 
 76 |     # mac
 77 |     source venv/bin/activate
 78 |     ```
 79 | 
 80 | 4. Install python dependencies
 81 | 
 82 |     ```bash
 83 |     pip install -r requirements.txt
 84 |     ```
 85 | 
 86 | 5. Run Application
 87 | 
 88 |     ```bash
 89 |     python main.py
 90 |     ```
 91 | 
 92 | ## Packaging for distribution
 93 | 
 94 | ### Build react app
 95 | 
 96 | Static files will be built in the `./build` directory
 97 | 
 98 | ```bash
 99 | yarn build
100 | ```
101 | 
102 | ### Build PyQt app
103 | 
104 | (I am still figuring this out)
105 |

/server/api/README.md:
--------------------------------------------------------------------------------
  1 | # API
  2 | 
  3 | ## Creating new API group
  4 | 
  5 | 1. Create new file in this directory
  6 | 
  7 |     For example, `server/api/foo.py`
  8 | 
  9 | 2. Create new PyQt Widget using the following template
 10 | 
 11 |     Rename Foo to the API group's name and foo to the API's name accordingly.
 12 | 
 13 |     ```py
 14 |     import json
 15 | 
 16 |     from PyQt5.QtCore import pyqtSlot, QObject
 17 | 
 18 | 
 19 |     class Foo(QObject):
 20 |         def __init__(self, parent=None):
 21 |             super().__init__(parent)
 22 | 
 23 |         @pyqtSlot()
 24 |         def foo(self):
 25 |             print('bar')
 26 |     ```
 27 | 
 28 | 3. Export API group from api module
 29 | 
 30 |     ```py
 31 |     # server/api/__init__.py
 32 | 
 33 |     from .foo import *
 34 |     ```
 35 | 
 36 | 4. Add API group as channel to PyQt Web Server
 37 | 
 38 |     ```py
 39 |     # main.py
 40 | 
 41 |     from server.api import Foo  # Add this line
 42 | 
 43 |     class WebEngineView(QWebEngineView):
 44 | 
 45 |         def __init__(self):
 46 |             super().__init__()
 47 | 
 48 |             ...
 49 | 
 50 |             # setup channel
 51 |             self.channel = QWebChannel()
 52 |             self.channel.registerObject('foo', Foo(self))  # Add this line
 53 |             self.page().setWebChannel(self.channel)
 54 | 
 55 |             self.show()
 56 |     ```
 57 | 
 58 | ## pyqtSlot
 59 | 
 60 | There is not a lot of examples found online regarding pyqtSlot. You may reference to the following documentation.
 61 | <https://doc.qt.io/qtforpython-6/PySide6/QtCore/Slot.html>
 62 | 
 63 | But for our purpose, the following guide should suffice.
 64 | 
 65 | ### Add arguments
 66 | 
 67 | To add a new argument, first specify the argument type in the pyqtSlot decorator `[float, int, str]`
 68 | 
 69 | ```py
 70 | @pyqtSlot(str, int)
 71 | def foo(self, mystr):
 72 |     print(mystr)
 73 | ```
 74 | 
 75 | I haven't figured out how to pass python or node.js object into slots yet, for now, you may make use of json.
 76 | 
 77 | ```py
 78 | import json
 79 | 
 80 | ...
 81 | 
 82 | # Receive
 83 | 
 84 | @pyqtSlot(str)
 85 | def foo(self, myobjectjson):
 86 | 
 87 |     myobject = json.loads(myobjectjson)
 88 |     print('My Object', myobject)
 89 | 
 90 | 
 91 | # Return
 92 | 
 93 | @pyqtSlot(result=str)
 94 | def foo(self, myobjectjson):
 95 |     myobject = {
 96 |         'text': 'some text',
 97 |         'list': ['1', 2],
 98 |     }
 99 |     myobjectjson = json.dump(myobject)
100 | 
101 |     return myobjectjson
102 | ```
103 |
