# 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](https://docs.deeplint.com/developer-guide/broken-reference)

### 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**:

   ```bash
   pnpm version [major|minor|patch]
   ```
2. **Update Changelog**:\
   Update `CHANGELOG.md` with the changes in the new version.
3. **Create Release Commit**:

   ```bash
   git add CHANGELOG.md
   git commit -m "Release vX.Y.Z"
   ```
4. **Create Tag**:

   ```bash
   git tag vX.Y.Z
   ```
5. **Push Changes**:

   ```bash
   git push origin main --tags
   ```
6. **Create GitHub Release**:\
   Create a new release on GitHub with the release notes.
7. **Publish to npm**:

   ```bash
   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`:

```yaml
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
