此外,还会设置一个比较特殊的环境变量npm_lifecycle_event,表示正在运行的脚本名称。比如执行npm run serve的时候,process.env.npm_lifecycle_event值为serve,通过判断这个变量,可以将一个脚本使用在不同的npm scripts中。这里还要提一下上面说的钩子,npm_lifecycle_event可以和钩子配合使用,利用这个变量,在同一个脚本文...
module.exports=functionlifecycleInit(Lifecycle){Lifecycle.up.starting('foo',function(app){console.log("My module is so cool",app.config.appName);});}; 然后,在应用程序的lifecycle/foo.js 文件中, require('foo/lifecycle')(require('lifecycle')); Commands Lifecycle 提供了一个命令结构,以便您可以添...

Lifecycle sequence# The following diagram depicts the sequence of key application lifecycle events, from the time the application is bootstrapped until the node process exits. We can divide the overall lifecycle into three phases: initializing, running and terminating. Using this lifecycle, you can pl...

verbose lifecycle xxx: unsafe-perm in lifecycle true 报这个错误一般意味着程序崩掉了,大概率是因为内存不足,比如打包压缩js时很耗内存,内存耗完直接崩了。 解决办法:换一个好的环境或者去掉一些消耗内存的打包配置,比如,webpack --progress --colors --bail --profile,其中“--profile”和"--progress"都是...
