CJ Silverio, que deixou o cargo de diretora t\u00e9cnica da NPM Inc no final do ano passado, apresentou<\/a><\/noindex> um novo reposit\u00f3rio de pacotes Entropic<\/a><\/noindex>, que se desenvolve como uma alternativa distribu\u00edda ao NPM, n\u00e3o controlada por uma empresa espec\u00edfica. O c\u00f3digo Entropic \u00e9 escrito em JavaScript e \u00e9 distribu\u00eddo<\/a><\/noindex> licenciado sob a Apache 2.0. O projeto est\u00e1 em desenvolvimento h\u00e1 apenas um m\u00eas e est\u00e1 na fase inicial de prot\u00f3tipo, mas j\u00e1 suporta opera\u00e7\u00f5es b\u00e1sicas, como conex\u00e3o, publica\u00e7\u00e3o e instala\u00e7\u00e3o de pacotes.<\/p>\n

A raz\u00e3o dada para a cria\u00e7\u00e3o do Entropic \u00e9 a completa depend\u00eancia do ecossistema JavaScript\/Node.js da NPM Inc, que controla o desenvolvimento do gerenciador de pacotes e a manuten\u00e7\u00e3o do reposit\u00f3rio NPM. Formou-se uma situa\u00e7\u00e3o em que uma empresa voltada para o lucro controla unilateralmente um sistema do qual dependem milh\u00f5es de desenvolvedores e aplicativos em JavaScript, e que processa bilh\u00f5es de downloads de pacotes por semana.<\/p>\n

Uma recente onda de demiss\u00f5es, mudan\u00e7as na lideran\u00e7a e a intera\u00e7\u00e3o da NPM Inc com investidores geraram uma sensa\u00e7\u00e3o de incerteza sobre o futuro da NPM e desconfian\u00e7a de que a empresa defender\u00e1 os interesses da comunidade, e n\u00e3o dos investidores. Segundo Silverio, o neg\u00f3cio da NPM Inc n\u00e3o \u00e9 confi\u00e1vel, pois a comunidade n\u00e3o tem meios de responsabiliz\u00e1-la por suas a\u00e7\u00f5es. Al\u00e9m disso, a orienta\u00e7\u00e3o para obter lucro dificulta a implementa\u00e7\u00e3o de possibilidades que s\u00e3o primordiais do ponto de vista da comunidade, mas que n\u00e3o geram dinheiro e exigem recursos adicionais, como suporte \u00e0 verifica\u00e7\u00e3o via assinatura digital. <\/p>\n

Silv\u00e9rio tamb\u00e9m duvida que a NPM Inc esteja interessada em otimizar a intera\u00e7\u00e3o com seu backend, pois isso levaria \u00e0 redu\u00e7\u00e3o dos fluxos de dados potencialmente interessantes do ponto de vista da monetiza\u00e7\u00e3o. A cada execu\u00e7\u00e3o do comando «npm audit<\/a><\/noindex>» o conte\u00fado do arquivo \u00e9 enviado para fora package-lock<\/a><\/noindex>, que inclui muitas informa\u00e7\u00f5es interessantes sobre o que o desenvolvedor est\u00e1 fazendo. Como resposta, alguns membros proeminentes da comunidade JavaScript\/Node.js come\u00e7aram a desenvolver uma alternativa que n\u00e3o est\u00e1 sob o controle de empresas espec\u00edficas.<\/p>\n

O sistema Entropic utiliza o princ\u00edpio de uma rede federativa, onde o desenvolvedor pode implantar um servidor com um reposit\u00f3rio de pacotes utilizados em suas pr\u00f3prias instala\u00e7\u00f5es e conect\u00e1-lo a uma rede distribu\u00edda comum, unindo reposit\u00f3rios privados dispersos em um todo. O Entropic pressup\u00f5e a conviv\u00eancia de muitos reposit\u00f3rios, com os quais a intera\u00e7\u00e3o ocorre no \u00e2mbito do fluxo de trabalho habitual. <\/p>\n

Todos os pacotes s\u00e3o separados usando namespaces e incluem informa\u00e7\u00f5es sobre o host no qual seu reposit\u00f3rio prim\u00e1rio est\u00e1 hospedado.
\n O espa\u00e7o de nomes representa, na ess\u00eancia, o nome do propriet\u00e1rio do pacote ou do grupo de mantenedores que t\u00eam o direito de lan\u00e7ar atualiza\u00e7\u00f5es. Em termos gerais, o endere\u00e7o do pacote tem a forma «namespace@repohost.com\/pkg-name».
\nOs metadados e as informa\u00e7\u00f5es sobre depend\u00eancias s\u00e3o definidos no formato TOML<\/a><\/noindex>.<\/p>\n

No caso de um pacote hospedado em um reposit\u00f3rio local com depend\u00eancias de outros reposit\u00f3rios, esses pacotes s\u00e3o espelhados no reposit\u00f3rio local. Assim, o reposit\u00f3rio local torna-se autossuficiente e inclui c\u00f3pias de todas as depend\u00eancias necess\u00e1rias. H\u00e1 uma camada para a intera\u00e7\u00e3o com o reposit\u00f3rio NPM cl\u00e1ssico, que \u00e9 tratado como um arquivo dispon\u00edvel apenas para leitura. Al\u00e9m disso, \u00e9 poss\u00edvel instalar pacotes do NPM usando ambientes Entropic implantados localmente. <\/p>\n

Uma ferramenta de linha de comando \u00e9 fornecida para facilitar a implanta\u00e7\u00e3o de reposit\u00f3rios em sua rede local. O Entropic oferece um API orientado a arquivos<\/a><\/noindex> e um sistema de armazenamento que minimiza a quantidade de dados transferidos pela rede. O Entropic \u00e9 apresentado como um sistema universal que pode ser aplicado para criar reposit\u00f3rios de pacotes em quaisquer linguagens de programa\u00e7\u00e3o, mas, ainda assim, o Entropic \u00e9 desenvolvido com foco em JavaScript e se adapta melhor a projetos nessa linguagem. <\/p>\n
