find-modules-in

Install

npm install --save find-modules-in

Usage

var find_modules = require('find-modules-in');

find_modules('some_directory').then(function(modules){
    console.log('modules =');
    console.log(modules);
}).catch(function(e){
    console.log('failed!');
    console.log(e);
});

Search in the node_modules:

var find_modules = require('find-modules-in');

find_modules('project/node_modules').then(function(modules){
    console.log('modules =');
    console.log(modules);
}).catch(function(e){
    console.log('failed!');
    console.log(e);
});

About

This modules finds modules just inside a directory. It only searches in the directory specified.

Modules that find-modules-in looks for are ones that are contained in there own directory. Some modules that people create are just a file. find-modules-in doesn't look for those kinds of modules that aren't contained in their own directory.

find-modules-in also does not check if found modules contain valid code. Once modules are found you can of course run the index.js files through a linter, but their's no guaruntee sub-modules will be valid. Which you probably knew already. :)

API

find_modules(directory, indexes) -> promise

Look for modules under directory.

indexes is optional, and default false.

If indexes is passed false modules only with package.json files will be searched for.

If indexes is passed true modules that contain index.js, or index.node files will also be searched for.

If indexes is passed an array of file name strings those are the indexed files that will be searched for when there's no package.json file.

modules

The array returned from the promise has these properties:

modules[index].directory

The directory is the one installed with npm install.

modules[index].package

If there is a package.json file this is the JSON object from that file.

package.readme

In order to keep memory size down the readme field is truncated. Some readmes are huge. If you want the full readme text you'll have to obtain it in your own code.

modules[index].index

modules[index].main

If the module doesn't have a package.json, and the indexes options is used in the find-modules-in function then the modules[index].index, and modules[index].main properties will be the main javascript file.

modules[index].packageError

If there was a JSON.parse error on the package.json contents packageError will have error text assigned to it. If no parse error happened packageError is set to null.
