Versionamento Semântico

Automatize o gerenciamento de versões e a geração de changelogs seguindo os princípios do SemVer.

Pré-requisitos

• Repositório Git com histórico de commits
• Node.js (para a maioria das ferramentas)
• Commits convencionais (recomendado)

Noções Básicas de Versionamento Semântico

Formato da Versão

MAJOR.MINOR.PATCH[-PRERELEASE][+BUILD]

Examples:
1.0.0
2.1.3
1.0.0-alpha.1
1.0.0-beta.2+build.123

Componentes da Versão

Precedência de Versão

1.0.0-alpha < 1.0.0-alpha.1 < 1.0.0-alpha.beta
< 1.0.0-beta < 1.0.0-beta.2 < 1.0.0-beta.11
< 1.0.0-rc.1 < 1.0.0 < 2.0.0

Commits Convencionais para Versão

Commit Type → Version Bump:
  feat:     → MINOR
  fix:      → PATCH
  docs:     → PATCH (or no release)
  style:    → PATCH (or no release)
  refactor: → PATCH
  perf:     → PATCH
  test:     → No release
  chore:    → No release
  
  BREAKING CHANGE: → MAJOR
  feat!:   → MAJOR
  fix!:    → MAJOR

Integração com GitHub Actions

# .github/workflows/release.yml
name: Release

on:
  push:
    branches: [main]

jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0
          persist-credentials: false

      - uses: actions/setup-node@v4
        with:
          node-version: '20'

      - run: npm ci

      - name: Release
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          NPM_TOKEN: ${{ secrets.NPM_TOKEN }}
        run: npx semantic-release

standard-version

Uso

# Primeiro lançamento
npx standard-version --first-release

# Lançamento regular (detecta automaticamente o aumento da versão)
npx standard-version

# Aumento de versão específico
npx standard-version --release-as minor
npx standard-version --release-as 1.1.0

# Pré-lançamento
npx standard-version --prerelease alpha
