package.json中的相对路径？

问题描述

我有一个项目，其中 src / main / webapp / com / mycompany / frontend / page / index.js 取决于 target / webjars / log4javascript / 1.4.10 / log4javascript.js 。

我添加了 package.json 和 index.js 一起放入以下内容：

  {
浏览器：
 {
log4javascript：../../../../../../../target/webjars/log4javascript/ 1.4.10 / log4javascript.js

} 
  

我已经在目标目录中有许多其他依赖项。有没有办法避免为每个依赖重复 ../../../../../../../target/ ？

解决方案

查看。

您可以使用grunt -browserify的aliasMapping选项指定应用程序的根目录：

  aliasMappings：[{
 cwd：'src'， 
 dest：'myApp'，
 src：['** / *。js'] 
}] 
  

然后您可以直接引用根路径中的所有内容，而不必使用任何可怕的 ../ 的：

  require（myApp / target / webjars / log4javascript / 1.4.10 / log4javascript.js）
  code> 

当然，这并不能解决问题，它仍然是一条很长的路。

这篇文章的下一段提到了一个很好的观点：如果你在应用程序的另一端调用了这样的方法，这是一个很好的迹象，表明事物可能没有正确构建。

你能分割功能吗进入更小的模块？也许让log4javascript成为自己的模块？

添加到我的答案中，从以下讨论：

如果log4javascript作为浏览器（非NPM）模块存在于package.json文件中，那么您应该只需要 require（'log4javascript'）

I've got a project where src/main/webapp/com/mycompany/frontend/page/index.js depends on target/webjars/log4javascript/1.4.10/log4javascript.js.

I've added package.json alongside index.js with the following contents:

{
    "browser":
        {
            "log4javascript": "../../../../../../../target/webjars/log4javascript/1.4.10/log4javascript.js"
        }
}

I've got many other dependencies in the target directory. Is there a way for me to avoid repeating ../../../../../../../target/ for every dependency?

解决方案

Check out the section Using Non-Relative Paths in this article.

You can use grunt-browserify's aliasMapping option to specify the root of your app:

aliasMappings: [{
  cwd: 'src',
  dest: 'myApp',
  src: ['**/*.js']
}]

and then you can directly refer to everything from the root path, without having to ever use any dreaded ../'s:

require("myApp/target/webjars/log4javascript/1.4.10/log4javascript.js")

Of course, this doesn't resolve the problem that it's still a very long path.

The article's next paragraph makes a very good point: if you're calling things way over at the other end of your application like that, it's a good sign that things may not be correctly architected.

Can you split the functionality into smaller modules? Perhaps make log4javascript its own module?

Add to my answer, from discussion below:

If log4javascript is in your package.json file as a browser (non-NPM) module, you should just be able to require it with require('log4javascript')
