J'ai adopté la philosophie de Svelte : plutôt que gérer les langues au runtime, j'en ai fait un maximum à la compilation pour avoir le code le plus léger possible. Dans cette conf' je vais donc vous parler de comment j'ai utilisé Rollup, Babel, svelte-i18n et autres joyeusetés pour avoir une application multilingue qui pèse moins 1kb de plus que l'application simple. I adopted the Svelte philosophy: instead of managing languages at runtime, I did as much as possible at compile time to get the lightest possible code. In this talk, I'm going to tell you how I used Rollup, Babel, svelte-i18n, and other fun tools to create a multilingual app that's less than 1kb larger than the single-language version.
