ruby-on-rails - Webpacker 在公共/资产中缓慢和重复文件

问题描述

使用 Rails / Webpacker 编译资产。

Webpacker 开始变得非常慢（3 分钟编译时间）。我注意到该public/assets文件夹​​中充满了指纹资产，例如..

application-1e69eb85a81f4a963fde.js application-828cf61e1e6dc295ffee.js application-95ba1bc02eaf571bca3d.js

每次页面刷新都会创建新的。

我在开发模式下启动服务器，我不确定为什么每次刷新都会产生一个新的指纹资产。但我的猜测是这就是导致问题的原因。

有没有人经历过这个？

解决方案

我正在添加这个答案，以便它可以帮助其他用户。

如果您不想在不重新加载浏览器的情况下更新 js 文件，请关闭 hmr 设置。

hmr: false

In RAILS, webpacker.yml has different settings, and one of those is hmr, which is Hot Module replacement, a Webpack feature that updates your Javascript without a browser reload. The 'module' in hot module replacement just refers to each of your Javascript source code files. To make these updates happen, Webpack installs the HMR Runtime into your output bundle.
