Nodemon手表选项损坏 [英] Nodemon watch option broken

问题描述

我正在使用 gulp-nodemon

config目录只包含一个文件server.js。

  $。nodemon（{
脚本：'config / server.js'，
 watch：['config / ** / *。 （）; 
 .on（'restart'，function（）{
 setTimeout（function（）{
 $ .livereload.changed（）; 
 }，1000）; 
}）; 
  

输出：

  [gulp] [nodemon] v1.2.1 
 [gulp] [nodemon]随时重启，输入`rs` 
 [gulp] [nodemon]正在看：config / ** /*.js 
 [gulp] [nodemon]启动`node config / server.js` 
 [gulp] [nodemon]观看34,325个文件 - 这可能会导致CPU使用率过高。减少使用 - 观察。 
  

如果我包含一个忽略选项，它会修正。

 忽略：[
'node_modules / **'，
'bower_components / **'
] 
  
 
 
 
为什么nodemon会监视所有事件>从输出中看，它只能看到配置目录 [nodemon]正在看：config / ** / *。js  
解决方案
这似乎是  nodemon  本身，因为我可以使用简单的 nodemon 命令重现它： 
 
 
 > nodemon --watch app server.js 
 [nodemon] v1.2.1 
 [nodemon]随时重启，输入`rs` 
 [nodemon]观看：app / ** / * 
 [nodemon]启动`node server.js` 
 [nodemon]观察72,981个文件 - 这可能会导致CPU使用率过高。减少使用--watch
  
默认行为 nodemon 是监视项目根目录中的所有目录
并忽略一些目录，如 node_modules ， bower_components 或 .sass_cache 。这个默认的 ignore 实际上不起作用，但是在这个PR中修复了。应用此修复程序，我的输出与预期一致。 
 
 
 > nodemon --watch app server.js 
 [nodemon] v1.2.1 
 [nodemon]随时重启，输入`rs` 
 [nodemon]观看：app / ** / * 
 [nodemon]启动`node server.js` 
  
我使用两种配置进行测试，即使发出警告，我的 nodemon 不会刷新不在指定的监视的目录中的文件更改，并且正如预期的那样工作，没有性能问题。这很可能是对我的假阳性警告。
 
 
 
但现在我建议你留在忽略直到它被合并到 nodemon 或者找到另一个解决方法。
 
 
 
这里有一些相关的问题：＃46 ，＃366 和＃32  
 
I am using gulp-nodemon

config directory includes only one file, server.js.
$.nodemon({
  script: 'config/server.js',
  watch: ['config/**/*.js']
})
.on('restart', function () {
  setTimeout(function () {
    $.livereload.changed();
   }, 1000);
 });
Output:
[gulp] [nodemon] v1.2.1
[gulp] [nodemon] to restart at any time, enter `rs`
[gulp] [nodemon] watching: config/**/*.js
[gulp] [nodemon] starting `node config/server.js`
[gulp] [nodemon] watching 34,325 files - this might cause high cpu usage. To reduce use "--watch".
If i include an ignore option it fixes.
ignore: [
  'node_modules/**',
  'bower_components/**'
]
Why does nodemon watch everything even when I tell it to watch only config directory?

Also it appears from the output it only watches the config directory [nodemon] watching: config/**/*.js
解决方案
This seems to be a bug with nodemon itself, because I was able to reproduce it using the simple nodemon command :
> nodemon --watch app server.js
[nodemon] v1.2.1
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: app/**/*
[nodemon] starting `node server.js`
[nodemon] watching 72,981 files - this might cause high cpu usage. To reduce use "--watch"
The default behavior of nodemon is to watch all the directories in the root of your project, 
and to ignore some directories like node_modules, bower_components or .sass_cache. This default ignore don't work actually, but was fixed in this PR. Applying this fix, my output was just as expected.
> nodemon --watch app server.js
[nodemon] v1.2.1
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: app/**/*
[nodemon] starting `node server.js`
I tested using both configurations, and even with the warning, my nodemon was not refreshing on a file change that is not in the specified watched directory, and working just as expected with no performance issue. It's more likely a false-positive warning to me.

But for now I advice you to stay with your ignore rule until this is merged into nodemon or another workaround is found.
