Development Workflow

This document outlines the development workflow for the DeepLint project, including the process for planning, implementing, testing, and releasing changes.

Development Lifecycle

The DeepLint development lifecycle follows these stages:

1. Planning

Before writing any code, we plan the changes to ensure they align with the project's goals and architecture:

• Feature Planning: Define the scope, requirements, and acceptance criteria

• Architecture Design: Design the high-level architecture and component interactions

• Task Breakdown: Break down the work into manageable tasks

• Issue Creation: Create GitHub issues for each task

2. Implementation

During implementation, we follow these practices:

• Branch Creation: Create a feature branch from the main branch

• Test-Driven Development: Write tests before implementing features

• Incremental Development: Make small, focused commits

• Documentation: Update documentation alongside code changes

• Code Quality: Follow the coding standards

3. Testing

Testing is an integral part of the development process:

• Unit Testing: Test individual components in isolation

• Integration Testing: Test interactions between components

• End-to-End Testing: Test the entire application flow

• Manual Testing: Perform manual testing for user experience

4. Code Review

All changes undergo code review before integration:

• Pull Request Creation: Create a pull request with a clear description

• Code Review: At least one team member reviews the changes

• Addressing Feedback: Address all feedback from reviewers

• Approval: Obtain approval from reviewers

5. Integration

Once approved, changes are integrated into the main branch:

• Merge: Merge the feature branch into the main branch

• CI/CD: Continuous integration runs tests and builds

• Deployment: Deploy to staging environment for further testing

6. Release

Releases follow a structured process:

• Version Bump: Update version numbers according to semantic versioning

• Changelog: Update the changelog with new features and fixes

• Release Notes: Create detailed release notes

• Tag: Create a Git tag for the release

• Publish: Publish the package to npm

Git Workflow

DeepLint follows a GitHub Flow-based workflow:

Branch Types

• main: The primary branch containing the latest stable code

• feature/*: Feature branches for new features

• fix/*: Fix branches for bug fixes

• docs/*: Documentation branches for documentation changes

• refactor/*: Refactoring branches for code improvements

Branch Lifecycle

1. Creation: Create a branch from the main branch

2. Development: Make changes and commit them

3. Push: Push the branch to the remote repository

4. Pull Request: Create a pull request for review

5. Review: Address feedback from reviewers

6. Merge: Merge the branch into the main branch

7. Cleanup: Delete the branch after merging

Release Process

DeepLint follows semantic versioning (MAJOR.MINOR.PATCH):

• MAJOR: Incompatible API changes

• MINOR: Backward-compatible new features

• PATCH: Backward-compatible bug fixes

Release Steps

1. Version Bump:

   pnpm version [major|minor|patch]

2. Update Changelog: Update CHANGELOG.md with the changes in the new version.

3. Create Release Commit:

   git add CHANGELOG.md
   git commit -m "Release vX.Y.Z"

4. Create Tag:

   git tag vX.Y.Z

5. Push Changes:

   git push origin main --tags

6. Create GitHub Release: Create a new release on GitHub with the release notes.

7. Publish to npm:

   pnpm publish

Continuous Integration

DeepLint uses GitHub Actions for continuous integration:

CI Workflow

1. Checkout: Check out the code

2. Setup: Set up Node.js and pnpm

3. Install: Install dependencies

4. Lint: Run linting checks

5. Test: Run tests

6. Build: Build the project

7. Publish: Publish to npm (for releases)

CI Configuration

The CI configuration is defined in .github/workflows/ci.yml:

name: CI

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v4
      - name: Use Node.js
        uses: actions/setup-node@v4
        with:
          node-version: "22.x"
      - name: Setup pnpm
        uses: pnpm/action-setup@v2
        with:
          version: 10.x
      - name: Install dependencies
        run: pnpm install
      - name: Lint
