Find package.json files in parent directories, keep finding until you find the right one using iterators.
npm install find-package-jsonEasily find package.json files that you're searching for. It spiders parent
directories for package.json files and correctly reads the results. It follows
an ES6 iterator design so it should be easy to implement.
The module is released in the public npm registry and can be installed by
running:
``
npm install --save find-package-json
We expose a single function as module interface. So in all examples we assume
that you've already required the code as illustrated in the example below:
`js
'use strict';
var finder = require('find-package-json');
`
The function accepts 1 optional argument which is the directory it should start
searching in or a module object with a filename key. If nothing is providedprocess.cwd()
it will default to as entry point.
As we're build upon the iterator interface you can simply call the .next()
function of the returned result to find the first package.json. If you don't
like the result, call again to find the next file. Please do note that
these methods do synchronous API calls in Node.js so they are blocking.
`js
var f = finder(__dirname);
console.log(f.next().value); // the package.json object
console.log(f.next().filename); // the path to the package.json file
`
You can also search for the global module object:
`js
var f = finder(module);
console.log(f.next().value); // the package.json object
console.log(f.next().filename); // the path to the package.json file
`
If there is no more package.json's to be found, the method will set the returned
done key as true;
`js
var f = finder(__dirname);
f.next().done // false
f.next().done // true
