Environment management in Supabase - Mini Project: Build & Apply

Environment Management with Supabase

📖 Scenario: You are working on a web app project that uses Supabase as its backend. You want to manage different environments like development and production to keep your data and settings separate and safe.

🎯 Goal: Build a simple environment management setup in Supabase by creating environment variables and using them to configure your project connection.

📋 What You'll Learn

Create a dictionary to hold environment variables for development and production

Add a variable to select the current environment

Write a function to get the correct Supabase URL and key based on the selected environment

Use the function to set up the Supabase client configuration

💡 Why This Matters

🌍 Real World

Managing different environments helps keep development and production data separate and secure, preventing accidental data loss or exposure.

💼 Career

Environment management is a key skill for cloud developers and DevOps engineers to ensure safe and reliable deployments.

1

Create environment variables dictionary

Create a dictionary called env_vars with two keys: development and production. Each key should map to another dictionary containing SUPABASE_URL and SUPABASE_KEY with these exact values:

development: SUPABASE_URL = "https://dev.supabase.co", SUPABASE_KEY = "devkey123"
production: SUPABASE_URL = "https://prod.supabase.co", SUPABASE_KEY = "prodkey456"

Supabase

# Create the env_vars dictionary with development and production keys
# Your code here

Hint

Use a dictionary with nested dictionaries for each environment.

2

Add current environment selector

Create a variable called current_env and set it to the string "development" to select the current environment.

Supabase

env_vars = {
    "development": {
        "SUPABASE_URL": "https://dev.supabase.co",
        "SUPABASE_KEY": "devkey123"
    },
    "production": {
        "SUPABASE_URL": "https://prod.supabase.co",
        "SUPABASE_KEY": "prodkey456"
    }
}
# Set current_env to 'development'
# Your code here

Hint

Just assign the string "development" to current_env.

3

Create function to get environment config

Write a function called get_supabase_config that takes no arguments and returns the dictionary of SUPABASE_URL and SUPABASE_KEY for the current environment using current_env and env_vars.

Supabase

env_vars = {
    "development": {
        "SUPABASE_URL": "https://dev.supabase.co",
        "SUPABASE_KEY": "devkey123"
    },
    "production": {
        "SUPABASE_URL": "https://prod.supabase.co",
        "SUPABASE_KEY": "prodkey456"
    }
}

current_env = "development"

# Define get_supabase_config function
# Your code here

Hint

Return the dictionary for the key current_env from env_vars.

4

Set up Supabase client configuration

Create a variable called supabase_config and set it to the result of calling get_supabase_config(). This will hold the current environment's Supabase URL and key.

Supabase

env_vars = {
    "development": {
        "SUPABASE_URL": "https://dev.supabase.co",
        "SUPABASE_KEY": "devkey123"
    },
    "production": {
        "SUPABASE_URL": "https://prod.supabase.co",
        "SUPABASE_KEY": "prodkey456"
    }
}

current_env = "development"

def get_supabase_config():
    return env_vars[current_env]

# Set supabase_config to the current environment config
# Your code here

Hint

Call the function and assign its result to supabase_config.
