Creating A CI Workflow To Detect Project Build Errors

by ADMIN 54 views

Introduction

In software development, Continuous Integration (CI) is a crucial practice that ensures code quality and reliability by automating the build, test, and deployment process. One of the key aspects of CI is detecting project build errors, which can significantly impact the overall development process. In this article, we will explore how to create a CI workflow to detect project build errors using GitHub Actions and a Makefile.

GitHub Workflow for CI Checks

The GitHub workflow is a YAML file that defines the CI pipeline for your project. It consists of several steps that perform various tasks, such as checking out the repository, setting up Node.js, installing dependencies, and running the build.

name: Project Build Checker

on:
  push:
    branches: [ main, master, development ]
  pull_request:
    branches: [ main, master, development ]
  workflow_dispatch:  # Allow manual triggering

jobs:
  build-check:
    runs-on: ubuntu-latest
    
    steps:
    - name: Checkout repository
      uses: actions/checkout@v3
      
    - name: Set up Node.js
      uses: actions/setup-node@v3
      with:
        node-version: '18'
        cache: 'npm'
        
    - name: Install dependencies
      id: install
      run: |
        npm ci
      continue-on-error: true
      
    - name: Check for dependency installation errors
      if: steps.install.outcome == 'failure'
      run: |
        echo "::error::Dependency installation failed"
        npm ci --verbose > dependency-error.log 2>&1
        echo "## Dependency Installation Error" > error-report.md
        echo "\`\`\`" >> error-report.md
        cat dependency-error.log >> error-report.md
        echo "\`\`\`" >> error-report.md
        exit 1
        
    - name: Analyze package.json
      id: analyze
      run: |
        echo "## Package.json Analysis" > package-analysis.md
        echo "### Project Dependencies:" >> package-analysis.md
        jq '.dependencies' package.json >> package-analysis.md
        echo "### Dev Dependencies:" >> package-analysis.md
        jq '.devDependencies' package.json >> package-analysis.md
        echo "### Scripts:" >> package-analysis.md
        jq '.scripts' package.json >> package-analysis.md
        
    - name: Run build
      id: build
      run: |
        npm run build
      continue-on-error: true
      
    - name: Report build errors
      if: steps.build.outcome == 'failure'
      run: |
        echo "::error::Build failed! See the error report for details."
        npm run build --verbose > build-error.log 2>&1
        echo "## Build Error Report" > error-report.md
        echo "\`\`\`" >> error-report.md
        cat build-error.log >> error-report.md
        echo "\`\`\`" >> error-report.md
        
    - name: Upload error report
      if: steps.install.outcome == 'failure' || steps.build.outcome == 'failure'
      uses: actions/upload-artifact@v3
      with:
        name: error-report
        path: |
          error-report.md
          package-analysis.md
          
    - name: Fail workflow build failed
      if: steps.build.outcome == 'failure'
      run: exit 1

Makefile for Local Build Error Detection

The Makefile is a file that defines a set of rules for building and testing your project. It provides a convenient way to perform checks locally before committing changes.

.PHONY: check-build check-dependencies analyze-package full-check clean

# Default target
help:
	@echo "Available commands:"
	@echo "  make check-build         - Check for build errors"
	@echo "  make check-dependencies  - Check for dependency issues"
	@echo "  make analyze-package     - Analyze package.json"
	@echo "  make full-check          - Run all checks"
	@echo "  make clean               - Remove log files"

# Check for build errors
check-build:
	@echo "Checking for build errors..."
	@npm run build > build.log 2>&1 || (echo "⛔ Build failed! See build.log for details"; cat build.log | grep -i "error"; exit 1)
	@echo "✅ Build successful!"

# Check for dependency issues
check-dependencies:
	@echo "Checking dependencies..."
	@npm ci > dependencies.log 2>&1 || (echo "⛔ Dependency installation failed! See dependencies.log for details"; cat dependencies.log | grep -i "error"; exit 1)
	@echo "✅ Dependencies installed successfully!"

# Analyze package.json
analyze-package:
	@echo "Analyzing package.json..."
	@if [ ! -f package.json ]; then echo "⛔ package.json not found!"; exit 1; fi
	@echo "📦 Project dependencies:"
	@cat package.json | grep -A 100 '"dependencies"' | grep -B 100 '"devDependencies"' | grep -v '"devDependencies"'
	@echo "🔧 Dev dependencies:"
	@cat package.json | grep -A 100 '"devDependencies"' | grep -B 100 -e '"scripts"' -e '$' | grep -v '"scripts"'
	@echo "🚀 Scripts:"
	@cat package.json | grep -A 100 '"scripts"' | grep -B 100 -e '"dependencies"' -e '"devDependencies"' -e '$' | grep -v '"dependencies"' | grep -v '"devDependencies"'
	@echo "✅ Analysis complete!"

# Run all checks
full-check: check-dependencies analyze-package check-build
	@echo "🎉 All checks passed successfully!"

# Clean log files
clean:
	@rm -f build.log dependencies.log
	@echo "🧹 Logs cleaned!"

Usage Instructions

GitHub Workflow:

  1. Create a .github/workflows directory in your repository if it doesn't exist
  2. Create a new file (e.g., build-checker.yml) in that directory with the GitHub workflow content
  3. Customize branch names and build commands based on your project needs
  4. Push the changes to trigger the workflow

Makefile:

  1. Place the Makefile in the root of your project
  2. Run make help to see available commands
  3. Run make full-check to perform all checks
  4. Check output logs for detailed error information

Additional Customization:

  • Adjust the Node.js version the workflow as needed
  • Modify build commands if your project uses a different build system
  • Add additional checks for linting, testing, etc.
  • For non-Node.js projects, replace npm commands with appropriate build tools
