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

Creation: Create a branch from the main branch
Development: Make changes and commit them
Push: Push the branch to the remote repository
Pull Request: Create a pull request for review
Review: Address feedback from reviewers
Merge: Merge the branch into the main branch
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

Version Bump:
```
pnpm version [major|minor|patch]
```
Update Changelog: Update CHANGELOG.md with the changes in the new version.

Create Release Commit:

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

Create Tag:
```
git tag vX.Y.Z
```
Push Changes:
```
git push origin main --tags
```
Create GitHub Release: Create a new release on GitHub with the release notes.
Publish to npm:
```
pnpm publish
```

Issue Management

Issues are tracked in GitHub and follow these guidelines:

Issue Types

Bug: Something isn't working as expected

Continuous Integration

DeepLint uses GitHub Actions for continuous integration:

CI Workflow

Checkout: Check out the code
Setup: Set up Node.js and pnpm
Install: Install dependencies
Lint: Run linting checks
Test: Run tests
Build: Build the project
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
        run: pnpm lint
      - name: Test
        run: pnpm test
      - name: Build
        run: pnpm build
