Creating Your CI/CD Pipeline Configuration File
 

• In the Lovable code editor, create a new file in your project’s root directory named lovable-ci.yml.
• This file will tell Lovable how to build, test, and deploy your project automatically.
• Paste the following code into lovable-ci.yml:

• 
  version: "1.0"
  
  steps:
  
  name: "Install Dependencies"
  Since Lovable does not have a terminal, we add the dependency instructions here.
    run: |
  # To install dependencies, ensure you have a file named 'requirements.txt' in your project root.
  # Lovable will read this file to know which packages to install.
  pip install -r requirements.txt
  
  name: "Run Tests"
  This step runs your tests to ensure everything works.
    run: |
  # Lovable looks for a test file named 'test_app.py' in the 'tests' folder.
  pytest tests/test_app.py
  
  name: "Deploy"
  This is where deployment commands go.
    run: |
  # Replace the command below with your actual deployment commands.
  echo "Deploying your lovable project..."
  

• Make sure you save the file. This configuration file sets the entire pipeline for your project.

 
Adding Dependencies Configuration
 

• Create a file called requirements.txt in the project root if you don’t already have one.
• Add the names of the libraries your project needs. For example, if you are using Flask and pytest, your file might look like:

• 
  Flask
  pytest
        

• This file allows Lovable to know what packages to install automatically during the "Install Dependencies" step.

 
Setting Up Your Test File
 

• In your project’s file structure, create a folder named tests (if it does not exist already).
• Inside the tests folder, create a new file called test\_app.py.
• Insert the following simple test code into test\_app.py to serve as an example test:

• 
  def test_basic_functionality():
      # This test checks that basic arithmetic works as expected.
      assert 1 + 1 == 2
        

• This file is referenced in part of the CI/CD pipeline for running tests.

 
Linking CI/CD Pipeline with Lovable
 

• Lovable automatically detects the lovable-ci.yml file in your project’s root directory.
• When you push changes to your project, Lovable will read this file and follow the steps to install dependencies, run tests, and deploy your project.
• No extra terminal commands are required; all instructions are embedded in the files you created.

 
Creating the CI/CD Workflow File
 

• Inside the project’s file structure, create a new folder called .github (if it doesn’t exist already). Within that folder, create another folder called workflows.
• In the workflows folder, create a file named ci-cd.yml. This file defines the steps that your project will follow during Continuous Integration and Continuous Deployment.
• Copy and paste the following code snippet into ci-cd.yml. This snippet sets up a basic pipeline that checks out your code, sets up a Python environment, installs dependencies, runs tests, and then triggers a deployment script.

name: CI/CD Pipeline

on:
  push:
    branches: [ main ]
  pull\_request:
    branches: [ main ]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
    - name: Checkout Code
        uses: actions/checkout@v2

    - name: Set Up Python
        uses: actions/setup-python@v2
        with:
          python-version: '3.x'

    - name: Install Dependencies
        run: |
          python dependency\_manager.py

    - name: Run Tests
        run: |
          python -m pytest

    - name: Deploy Application
        run: |
          python deploy.py

 
Configuring Dependency Installation within Your Code
 

• Because Lovable does not support terminal commands directly, add a dedicated script to handle installing dependencies.
• Create a file named dependency\_manager.py in the root of your project.
• Paste the code snippet below into dependency\_manager.py. This file checks if the required dependencies (listed in requirements.txt) are installed. If not, it installs them.

import subprocess

def install\_dependencies():
    try:
        # This command installs all packages listed in requirements.txt
        subprocess.check\_call(["pip", "install", "-r", "requirements.txt"])
        print("Dependencies installed successfully.")
    except Exception as error:
        print("Error installing dependencies:", error)

if **name** == "**main**":
    install\_dependencies()

• Make sure you create a file named requirements.txt in your project root, and list all necessary libraries (for example, Flask, pytest, etc.).

 
Integrating Automated Tests
 

• To ensure your project works correctly as changes are made, create automated tests.
• Create a file called test\_app.py in your project directory. This file will contain simple tests to check the main functionalities.
• Insert the following code into test\_app.py. The basic test provided always passes, but you can add more tests as needed.

def test\_example():
    # A simple test that always passes
    assert True, "This test is meant to pass"

if **name** == "**main**":
    test\_example()
    print("Tests executed successfully.")

• The CI/CD configuration in ci-cd.yml calls these tests automatically during each build.

 
Setting Up Deployment
 

• Deployment is the process where your project is moved to a live environment after passing all tests.
• Create a new file called deploy.py in the project root.
• Copy and paste the following code into deploy.py. This script simulates deployment. You can update it with your deployment logic (for example, copying files or triggering an API).

def deploy():
    try:
        # Insert your deployment logic here
        print("Deploying your application...")
        # For example, copying files or making API calls
        print("Deployment successful!")
    except Exception as error:
        print("Deployment failed:", error)

if **name** == "**main**":
    deploy()

• The deployment step in ci-cd.yml executes deploy.py after tests pass, ensuring only tested code is deployed.

 
Adding Error Handling and Logging
 

• For troubleshooting issues, add error handling and logging in your scripts to get more information about what went wrong.
• Create or update a file called logger\_setup.py to include logging configurations.
• Insert the following snippet into logger\_setup.py. This configuration enables your scripts to log errors and other helpful messages.

import logging

Configure logging to display messages in a simple format
logging.basicConfig(level=logging.INFO,
                    format='%(asctime)s - %(levelname)s - %(message)s')

def get\_logger():
    return logging.getLogger()

if **name** == "**main**":
    logger = get\_logger()
    logger.info("Logger is set up and running.")

• Make sure to import and use this logger in your other scripts (for example, dependency\_manager.py and deploy.py) to print useful debugging information.
