web-deploy

Purpose

This skill automates deployment of web applications to platforms like Cloudflare Pages/Workers, Vercel, Netlify, Docker, and GitHub Actions CI/CD pipelines. It focuses on streamlining the process from code commit to live deployment, handling configurations, builds, and environment integrations.

When to Use

Use this skill for deploying static sites, serverless functions, or containerized apps. Apply it when setting up CI/CD for frequent updates, migrating projects to cloud platforms, or automating deployments in response to GitHub events. Ideal for web-dev workflows involving version control and cloud services.

Key Capabilities

• Deploy static sites to Cloudflare Pages using Git integration or CLI.
• Handle serverless deployments to Cloudflare Workers via API or Wrangler CLI.
• Automate Vercel deployments with CLI commands and environment variables.
• Set up Netlify for site builds and deploys using their API or CLI.
• Containerize applications with Docker and orchestrate CI/CD via GitHub Actions.
• Manage pipelines that include build steps, testing, and deployment triggers.

Usage Patterns

Follow these patterns to integrate deployments into your workflow:

• For new projects, initialize with a platform-specific config file (e.g., vercel.json for Vercel).
• In CI/CD, trigger deployments on pull requests or merges using GitHub Actions workflows.
• Use environment variables for secrets, like $CLOUDFLARE_API_TOKEN for authentication.
• Example 1: Deploy a React app to Vercel—Clone repo, run npx vercel in project root, select options, and push changes.
• Example 2: Set up CI/CD for a Dockerized app—Create a .github/workflows/deploy.yml file with steps to build Docker image and deploy to Netlify via API call.

Common Commands/API

Use these exact commands and APIs for tasks:

• Cloudflare Pages: Run npx wrangler pages deploy ./build --project-name=my-site to deploy a build folder; API endpoint: POST https://api.cloudflare.com/client/v4/accounts/{account_id}/pages/projects/{project_name}/deployments with JSON body {"files": [...]}, auth via $CLOUDFLARE_API_TOKEN.
• Vercel: Execute npx vercel deploy --prod from project directory; config in vercel.json: {"version": 2, "builds": [{"src": "package.json", "use": "@vercel/node"}]}, auth with $VERCEL_TOKEN.
• Netlify: Command: netlify deploy --dir=build --prod; API: POST https://api.netlify.com/api/v1/sites/{site_id}/deploys with form data, using $NETLIFY_ACCESS_TOKEN.
• Docker: Build image with docker build -t my-app:latest .; Push to registry: docker push my-repo/my-app:latest.
• GitHub Actions: In YAML file, use: run: echo "::set-env name=GITHUB_TOKEN::${{ secrets.GITHUB_TOKEN }}" then run: gh workflow run deploy.yml; Example snippet:

  jobs:
    build:
      runs-on: ubuntu-latest
      steps:
        - uses: actions/checkout@v2
        - run: docker build . -t my-app

• For CI/CD, add workflow triggers: on: [push, pull_request] in .github/workflows/main.yml.

Integration Notes

Integrate by setting environment variables in your CI/CD config, e.g., add env: { API_KEY: ${{ secrets.SERVICE_API_KEY }} } in GitHub Actions. For multi-platform setups, use a monorepo with separate configs (e.g., netlify.toml and vercel.json). Link with GitHub by adding webhooks: POST to https://api.github.com/repos/{owner}/{repo}/hooks with JSON payload. Ensure Docker images are tagged correctly for deployments, like docker tag my-app:latest registry.example.com/my-app:1.0. For API integrations, handle rate limits by checking response headers like X-RateLimit-Remaining.

Error Handling

Handle errors by checking exit codes and logs; for CLI commands, use try-catch in scripts (e.g., in Bash: if ! npx vercel deploy; then echo "Deployment failed"; exit 1; fi). Common issues: Authentication failures—verify env vars like $CLOUDFLARE_API_TOKEN is set; resolve with export CLOUDFLARE_API_TOKEN=your_key. For API errors, parse responses (e.g., if status code is 429, wait and retry). In GitHub Actions, use continue-on-error: true for non-critical steps, then check outputs. Example snippet for error logging:

  try {
    await fetch('https://api.cloudflare.com/...', { headers: { Authorization: `Bearer ${process.env.CLOUDFLARE_API_TOKEN}` } });
  } catch (error) {
    console.error('API error:', error.message);
  }

Debug deployments by enabling verbose modes, like npx vercel deploy --debug.

Graph Relationships

• Related to cluster: web-dev (e.g., shares nodes with skills like web-build or api-integration).
• Connected via tags: deployment (links to ci-cd skills), ci-cd (connects to github-actions tools), cloudflare (associates with web-hosting skills), web (ties to frontend-dev capabilities).
