Guia de sobrevivência JS no mundo Open SourceRio.JS Conference 2013 - Leo Balter
JS no mundo Open Source?
JS no mundo Open Source?
JS de terceiros!
WAT?
Desafio Desenvolvedor
• 1 ambiente
• 1 versão da linguagem
• sem script no nome
Desafio DesenvolvedorJavaScript
• Vários ambientes (mobile, desktop, geladeira)
• Chrome, Firefox, Opera
• IE 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17...
• Qual é mesmo a versão do JS?
JS que funciona em qualquer site, inclusive nos que não são seus!
Primeiros perigos
Same Origin Policy
HTTP HTTP
HTTPS HTTPS
www.foo.com/bla www.foo.com/bos
Same Origin PolicyHTTP HTTPS
HTTPS HTTP
bla.foo.com bos.foo.com
Como driblar o SOP?
• JSONP (Jaydson P)
• CORS (Cross Origin Resource Sharing)
• Post Message https://developer.mozilla.org/en-US/docs/DOM/window.postMessage
• easyXDM http://easyxdm.net/wp/
Como se não bastasse...
Peraí, um JS de terceiros está bloqueando a apresentação
Nunca bloquear páginas alheias

Antipatterns
http://addyosmani.com/resources/essentialjsdesignpatterns/book/#antipatterns
Antipatterns comuns
• Muitas globais poluindo o contexto da página
• Modificar os objetos nativos do JS
• JavaScript inline
• document.write()
“Knowledge of anti-patterns is critical for success. Once we are able to
recognize such anti-patterns, we're able to refactor our code to negate
them so that the overall quality of our solutions improves instantly.”
http://addyosmani.com/resources/essentialjsdesignpatterns/book/#antipatterns
Addy Osmani:
“Conhecer os antipadrões é crítico para alcançar sucesso. Uma vez que
conseguimos reconhecer os antipadrões, conseguimos refatorar nosso código para evitá-los de modo
que a qualidade geral de nossas soluções melhore instantaneamente.”

Addy Osmani (em pt-BR):
Agora para tudo e vamos falar de jQuery!
Repositório de Plugins jQuery
Como faz?
Passo a passo
• Após criar um repositório no GitHub, crie um webhook apontando para a URL:
http://plugins.jquery.com/postreceive-hook
https://help.github.com/articles/post-receive-hooks
???
Você ainda não tem conta no GitHub?
É de graça!
Passo a passo
• Repositório GitHub WebHook para http://plugins.jquery.com/postreceive-hook
• Criar um arquivo de manifesto “seu-plugin.jquery.json”
