Я возился с различными функциями Webpack, и я медленно разбираюсь в вещах.
Типичный консольный вывод:
[WDS] App updated. Recompiling...
[WDS] App hot update...
[HMR] Checking for updates on the server...
[HMR] The following modules couldn't be hot updated: (They would need a full reload!)
[HMR] - 14
[HMR] Nothing hot updated.
[HMR] App is up to date.
Это происходит независимо от того, какая часть кода обновляется, JS, Stylus, шаблоны и т.д. Все проходит через преобразования (Babel, Stylus, Handlebars), но это не имеет значения.
У меня есть проект GitHub, если кто-то хочет просмотреть полный исходный код: https://github.com/SimenB/webpack-fun. npm install && npm start
, чтобы запустить его.
