npm-package-select

Select files inside node_modules/ reading a configuration file.

This module allows the selection of certain files of a npm-package.
It can be used with gulp to copy distribution files of packages to any destination you want.
A configuration file is used to specify all needed sources.

Install

``
$ npm install --save-dev npm-package-select
`

Prerequisites

Make sure that all configured packages are installed. npm-package-select cannot download a missing package.

Usage

1. Create a npmconfig.json specifying all needed files. The path of each file is relative to the corresponding npm-package.

Example The compiled source of requirejs is located in bin/r.js. If you want to use requirejs you have to use the mentioned path before.
In this sample js and css represent groups. Groups give the possibility to copy the specified sources into different destination directories.

`json
{
"js": [{
"requirejs": {
"files": ["bin/r.js"]
}
}],
"css": [{
"semantic-ui-css": {
"files": ["semantic.css"]
}
}]
}
`

2. Create a gulp task to copy the selected files to copy them to any destination.

`js
import {Gulpclass, Task, SequenceTask} from 'gulpclass/Decorators';
import * as gulp from 'gulp';

// Initialize npm-package-select
const NpmPackageSelect = require('npm-package-select');

@Gulpclass()
export class Gulpfile {

@Task('default', ['link'])
default() { }

@Task()
link(done: Function) {
// Read npmconfig.json
let selection = new NpmPackageSelect('./npmconfig.json');

// Read all groups of npmconfig.json
selection.groups().forEach(group => {

// Read all packages of a group
group.packages.forEach(p => {

// Pipe files of the package to a specified destination
gulp.src(p.files)
.pipe(gulp.dest(./content/assets/${group.name}/${p.name}));
})
});

done();
}
}
