In Node.js, how can a module get data from an application's package.json?

Question

I have a module. Inside it, I'd like to access data from my parent application's package.json file. What's the best practice way to do that? I've done this the janky way by going up 2 levels and requiring the file (or using the nconf configuration loader). ``` var appdir = path.resolve(__dirname, '../../'); nconf.file('app', path.join(appdir, 'package.json')); ``` But that seems like it could break easily. Also I heard about pkginfo, it will automatically grab info from my own module's package.json, but I'm looking to get data from the parent application's. Thanks for any help! EDIT: I suppose another way of asking is, how can I get the application's path (instead of the module path) ?

Accepted Answer

You can use

```
require.main.require './package'
```

But it'll work only if your parent application's file is in a root of it's directory.

You can also wrap it into `try ... catch` and add `../` to path till you find `package.json`.
