parcel-demo's Introduction

parcel-demo

parcel getting started

command

运行server,热更新,并build 默认端口号1234 parcel index.html

parcel index.html -p <port number>

热更新但不启动server parcel watch index.html

//打包 parcel build index.html 这将关闭监听模式和热模块替换,所以它只会编译一次。它还会开启 minifier 来减少输出包文件的大小。Parcel 使用的 minifiers 有 JavaScript 的 uglify-es ,CSS 的 cssnano 还有 HTML 的 htmlnano。

启动生产模式还要设置环境变量 NODE_ENV=production .

在js里import的css不生效

超过以及@import的css文件,热编译不生效,需要删除.cache后重新运行。
