在npm安装期间检测node-webkit [英] Detecting node-webkit during npm install
问题描述
我正在为主要作为本机模块构建的node.js库工作.因此，当人们尝试将其包含在node-webkit项目中时，他们必须使用nw-gyp而不是node-gyp重新编译它.我知道我们可以在构建的代码运行时使用以下特定方式检测到node-webkit:
I'm working on a library for node.js that is build primarily as a native module. As such, when people try to include it in node-webkit projects, they have to recompile it using nw-gyp instead of node-gyp. I know we can detect node-webkit specifically when our built code runs using something like this:
try {
isNodeWebkit = (typeof require('nw.gui') !== "undefined");
} catch(e) {
isNodeWebkit = false;
}
try {
isNodeWebkit = (typeof require('nw.gui') !== "undefined");
} catch(e) {
isNodeWebkit = false;
}
但是，我想在我们的安装脚本(由npm install运行)中检测到此错误.或者，我们查看自己的package.json，但是也许有办法查看根项目的package.json吗?这样，我们至少可以查看某些属性，也许是engine之类的东西?
However, I would like to detect this inside of our install script (run by npm install). Alternatively, we look in our own package.json, but is there maybe a way to look at the root project's package.json? That way we could at least look at some property, maybe engine or something?
推荐答案
我最终编写了一个模块来执行此操作: https://github.com/maxkorp/which-native-nodish (还支持atom-shell和重命名的nw.js)
I ended up writing a module to do this: https://github.com/maxkorp/which-native-nodish (also supports atom-shell and the renamed nw.js)
要点是，只要您是node_modules文件夹的子级(该文件夹是具有package.json的文件夹的子级)的子目录，便从该模块的父目录开始，并继续向上移动.进入根目录级别后，请检查package.json中的engines属性以获取atom-shell，node-webkit或nwjs属性.不能保证能正常工作(最远的祖先项目必须指定是否以这种方式使用节点式引擎)，但是总比没有好，而且是我见过的唯一的即用型解决方案.
The gist is that you start at the parent directory to the module, and keep going up as long as you are a child of a node_modules folder which is a child of a folder with a package.json. Once at the root level, check the engines property in the package.json for an atom-shell, node-webkit or nwjs property. Not guaranteed to work (The farthest ancestor project must specify if its using a node-ish engine in this way), but it's better than nothing, and the only out of the box solution I've seen.
