构建时与运行时 - 如何与包代码本身共享包.js中的变量/代码

Question

我有一个包，它需要为包、测试以及包本身（运行时）定义一堆资产文件（在构建时）。

有没有办法共享这些变量？例如：

// package.js
// var shared across test and package def
var BrainFiles = [
    "data/begin.rive",
    "data/start.rive",
    "data/nav.rive"
  ]
Package.on_use(function(api) {
  api.addFiles(BrainFiles, ['server'], 
    {isAsset: true} 
  )
  ...
}
Package.on_test(function (api) {
  api.addFiles(BrainFiles, ['server'], 
    {isAsset: true} 
  )
  ...
}
// then within the package code i want to refer to Brainfiles

我想另一种方法是编写文件夹扫描函数，但该代码也必须在包.js和包代码之间共享。

它并不漂亮，但我会创建一个Asset文件brain-files.json

//brain-files.json
[
  "data/begin.rive",
  "data/start.rive",
  "data/nav.rive"
]

使用fs在您的package.js中读取/解析它

//package.js
Package.on_use(function(api) {
  var fs = Npm.require('fs')
  var BrainFiles = JSON.parse(fs.readFileSync('brain-files.json'));
  api.addFiles(BrainFiles, 'server', {isAsset: true});
  // sets a `BrainFiles` variable for other files that are included
  api.addFiles('brain-files.json', 'server', {isAsset: true});
  api.addFiles('read-brain-files.js', 'server');
  ...
}

并在带有Assets.getText() read-brain-files.js的 js 文件中读取/解析

//read-brain-files.js
// no var, this should be accessible by all files in your package
BrainFiles = JSON.parse(Assets.getText('/packages/my-package/brain-files.json'));
