Readme
#load-package-async Asynchronously find-up and load the package.json associated with a given directory.
- Stops looking when the first package.json file is found
- Returns a promise which resolves to the loaded package.json object
- Stores a cache of promises associated with each directory requested.
Usage
The function returned by require('load-package-async')
takes a single argument,
the path to the directory where you want to start looking:
var loadPackage = require('load-package-async');
loadPackage('/a/b/c/d/e/f')
.then(function(package){
if (package)
console.log(package.name);
else
console.log('package not found');
})
.catch(function(error){
console.log('there was an error')
})
If an incorrect path is given or a correct path is given but no package.json file is found, the promise resolves to null.
If you wish to get the package.json for the current module:
loadPackage('./')
If you wish to purge the cache, you can call the flush
method:
loadPackage.flush()
