@labz/semver v0.0.5

labz-semver-npm

Testes de publicação de pacotes npm na org @labz

npmjs.com é utilizado para armazenar e versionar assets, mas não possui CDN próprio. Para isso existem duas soluções, jsdelivr.net e unpkg.com

O pacote público npm se chama: @labz/semver utilizando Versionamento Semântico 2.0.0

Setup

O mínimo necessário para publicar um package npm é o seguinte:

mkdir semver
cd semver
npm init --scope=@labz --force
echo 'alert("@labz/semver@0.0.0")' > index.js
npm publish --access public

output:

Publish

Utilizar tag para não atrapalhar versões em produção: (dev, test, beta, alpha, next. A tag padrão é latest)

npm publish --tag dev

curl -Li https://unpkg.com/@labz/semver@dev

Apenas ver quais arquivos serão enviados no package:

npm publish --dry-run

CDN

jsdelivr faz cache que precisa ser purged para limpar

curl -I https://cdn.jsdelivr.net/npm/@labz/semver
