Os desenvolvedores da biblioteca JavaScript Moment.js<\/a><\/noindex> anunciaram a interrup\u00e7\u00e3o<\/a><\/noindex> do desenvolvimento e a transi\u00e7\u00e3o do projeto para um estado de manuten\u00e7\u00e3o, que implica a parada da expans\u00e3o de funcionalidades, congelamento da API e limita\u00e7\u00e3o da atividade a corre\u00e7\u00f5es de erros graves, reflex\u00f5es sobre altera\u00e7\u00f5es da base de fusos hor\u00e1rios e manuten\u00e7\u00e3o da infraestrutura para os usu\u00e1rios existentes. Para novos projetos, o uso do Moment.js n\u00e3o \u00e9 recomendado. <\/p>\n

A biblioteca Moment.js fornece fun\u00e7\u00f5es para manipula\u00e7\u00f5es de tempo e datas e \u00e9 o padr\u00e3o de fato em sua \u00e1rea. Semanalmente, a biblioteca \u00e9 baixada<\/a><\/noindex> cerca de 12 milh\u00f5es de vezes. A raz\u00e3o para a decis\u00e3o tomada foi a percep\u00e7\u00e3o de que o projeto est\u00e1 desatualizado e n\u00e3o se encaixa nas modernas paradigmas de desenvolvimento em JavaScript.
\nEntre as desvantagens, menciona-se o tamanho relativamente grande da biblioteca (329KB sem compress\u00e3o, 70KB com compress\u00e3o) e o uso de objetos mut\u00e1veis (mutable<\/a><\/noindex>, a altera\u00e7\u00e3o de uma c\u00f3pia do objeto moment leva \u00e0 modifica\u00e7\u00e3o do original). <\/p>\n

Em \u00c9 importante notar qual funcionalidade os componentes do stack oferecido possuem:<\/a><\/noindex> tamb\u00e9m s\u00e3o mencionados<\/a><\/noindex> Problemas do Moment.js, como baixa performance, confus\u00e3o na API, falta de suporte «Tree shaking<\/a><\/noindex>» (remo\u00e7\u00e3o de c\u00f3digo n\u00e3o utilizado para reduzir o tamanho da aplica\u00e7\u00e3o web) e dificuldade de depura\u00e7\u00e3o. Aparentemente, a gota d'\u00e1gua que levou os desenvolvedores a decidir colocar o Moment.js em modo de manuten\u00e7\u00e3o foi a mudan\u00e7a no sistema de auditoria de p\u00e1ginas web Lighthouse, integrado \u00e0s ferramentas de desenvolvimento web do Chrome — h\u00e1 alguns dias, o Lighthouse se tornou<\/a><\/noindex> come\u00e7ou a emitir avisos sobre a excessiva bulking do c\u00f3digo do Moment.js e sugerir alternativas de substitui\u00e7\u00e3o.<\/p>\n

Os navegadores modernos oferecem uma API embutida Intl<\/a><\/noindex> para trabalhar com localidades e fusos hor\u00e1rios. Esta API \u00e9 utilizada na biblioteca Luxon<\/a><\/noindex>, criada por um dos participantes do desenvolvimento do Moment.js e apresentada como o pr\u00f3ximo passo na evolu\u00e7\u00e3o do Moment.js. Al\u00e9m do Luxon, como op\u00e7\u00f5es de substitui\u00e7\u00e3o, s\u00e3o mencionadas as bibliotecas Day.js<\/a><\/noindex> (uma variante minimalista do Moment.js com API similar, ocupa cerca de 7KB sem plugins), date-fns<\/a><\/noindex>, js-joda<\/a><\/noindex> (porta do java.time) e os objetos JavaScript padr\u00e3o Date<\/a><\/noindex> e Intl<\/a><\/noindex>, assim como a API em rascunho Temporal<\/a><\/noindex>.<\/p>\n
