To create and use environment variables in our project, we need to install a package for that such as python-dotenv for example.
pip install python-dotenv
As for the database, we could use MongoDB Atlas. If we have already an account with this modern database, we could create an environment variable for the URL to this database and connect to it using environment variable.
However, for Python to work smoothly with MongoDB Atlas, we need to install pymongo package.
pip install pymongo
To create and save user session, we can use Redis database by creating an account with Redis Enterprise platform and installing Redis package for Python.
pip install redis
One more thing, to authenticate user, we can use JSON Web Token (JWT) by installing PyJWT package.
pip install PyJWT
When everything is installed, we can create a configuration file to configure and setup database connections.
# config.py
# pip install python-dotenv
# pip install PyJWT
# pip install pymongo
# pip install redis
def settings():
setup = {
"siteTitle": "TV Channel",
"pageTitle": "",
}
return setup
import os
from dotenv import load_dotenv
load_dotenv()
secret_key = os.getenv("SECRET_KEY")
import pymongo
client = pymongo.MongoClient(os.getenv("DATABASE_URI"))
db = client[os.getenv("DB_NAME")]
import redis
redis = redis.Redis(
host = os.getenv("REDIS_URI"),
port = int(os.getenv("REDIS_PORT")),
password = os.getenv("REDIS_PASSWORD")
)
configure = {
"settings": settings,
"secret_key": secret_key,
"db": db,
"redis": redis,
}
# .env
SECRET_KEY=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
DATABASE_URI=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
DB_NAME=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
REDIS_URI=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
REDIS_PASSWORD=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
REDIS_PORT=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
We can import the configuration in the above file across different module. However, the best way is to store the configure object in the main application object. Doing so, we can use this configuration in any module through the request object.
# index.py
from bottle import static_file, get
from routes.frontend import index
import config
app = index.appIndex
app.config["myapp.config"] = config.configure
@app.get('/static/<filepath:path>')
def staticFile(filepath):
return static_file(filepath, root="public")

import socket
host = socket.getfqdn()
addr = socket.gethostbyname(host)
if(addr == '127.0.1.1'):
app.run(host='localhost', port=8000, debug=True, reloader=True)

setup["message"] = "Hello World!"
