Update .env.example file with production context details. Includes changes like modifying the CONTEXT from 'dev' to 'prod', adding MYSQL_HOST variable, and replacing MONGO_COLLECTION with MONGO_DATABASE.
This commit introduces some additional environment variables to the .env.exemple file. The new variables include settings for the application port, debug mode, context, MySQL port, and MongoDB port.
A new file, .env.example, has been added. It contains configuration for both MySQL and MongoDB, including username, password, and database information.
