README

This tool analyzes Laravel migration files and generates a summary of the database structure, including an Entity-Relationship Diagram (ERD) using Mermaid.js syntax.

NPM

COMPOSER

Package Name

The name of the package on the github repo is a portmanteau of 'Summed Up' to denote a summing up of the DB of the app.

The npm package name however is a clear and understandable 'laravel-db-summary'.

Installation

NPM:

You can install Laravel DB Summarizer globally using npm:

npm install -g laravel-db-summary

Or use it directly with npx:

npx laravel-db-summary

COMPOSER:

You can install the package via Composer:

composer require the-provost/laravel-summdb

Usage

NPM:

There are two ways to use Laravel DB Summarizer:

1. Interactive Mode: Run the tool without any arguments, and it will prompt you for the Laravel project path:

laravel-db-summary

1. Command Line Mode: Provide the path to your Laravel project as an argument:

laravel-db-summary /path/to/your/laravel/project

COMPOSER

After installation, you can use the Laravel SummDB command:

php artisan db:summarize

This command will analyze your Laravel migration files and generate a summary.

Output

The script generates three files in a 'db-summary' directory:

1. text-summary.txt: A text summary of each table, its columns, and foreign key relationships.
2. erd.mmd: Mermaid.js ERD code that can be visualized using tools like the Mermaid Live Editor.
3. erd.png: A PNG image of the Entity-Relationship Diagram (requires Mermaid CLI to be installed).

If you don't have Mermaid CLI installed, you can still use the erd.mmd file to generate the diagram online.

Requirements

• Node.js (version 12.0.0 or higher)
• A Laravel project with migration files

Integrating with CI/CD Pipeline

NPM:

To include Laravel DB Summarizer as part of your CI/CD pipeline, follow these steps:

1. Install Laravel DB Summarizer in your CI environment: Add this to your CI configuration file (e.g., .gitlab-ci.yml, .github/workflows/main.yml):

   - js install -g laravel-db-summary

2. Run Laravel DB Summarizer: Add a step in your CI pipeline to run the tool:

   - laravel-db-summary /path/to/your/laravel/project

3. Archive the generated files: Configure your CI to archive the db-summary directory as an artifact. For example, in GitLab CI:

   artifacts:
     paths:
       - db-summary/

4. Optional: Generate PNG in CI: If you want to generate the PNG in your CI pipeline, ensure Mermaid CLI is installed:

   - js install -g @mermaid-js/mermaid-cli

5. Example GitLab CI configuration:

   stages:
     - build
     - test
     - document
   
   document_db:
     stage: document
     script:
       - js install -g laravel-db-summary @mermaid-js/mermaid-cli
       - laravel-db-summary .
     artifacts:
       paths:
         - db-summary/

6. Example GitHub Actions workflow:

   name: Document Database
   on: [push]
   jobs:
     document:
       runs-on: ubuntu-latest
       steps:
       - uses: actions/checkout@v2
       - name: Use Node.js
         uses: actions/setup-node@v2
         with:
           node-version: '14'
       - run: js install -g laravel-db-summary @mermaid-js/mermaid-cli
       - run: laravel-db-summary .
       - uses: actions/upload-artifact@v2
         with:
           name: db-summary
           path: db-summary/

COMPOSER:

To include Laravel SummDB as part of your Laravel CI/CD pipeline, you can add the command to your build process. For example, in GitLab CI:

stages:
  - build
  - test
  - document

document_db:
  stage: document
  script:
    - php artisan db:summarize
  artifacts:
    paths:
      - db-summary/

By following these steps, you'll ensure that every build of your Laravel application includes an up-to-date database summary and ERD.

This script parses migration files statically and may not capture all complex scenarios or dynamic schema modifications. It's designed as a quick summary tool and may not reflect the exact state of a database that has undergone manual modifications or complex migrations.
