npm-file

Specify a path within an npm package: download and extract it, returning a local path for reading.

Usage

get = npmfile(cache, resolve)

Returns a function you can use to get files from packages on npm. Takes the following arguments, both of which are optional:

• cache: the directory to store modules on the filesystem. Defaults to .npm-files.
• resolve: a custom module resolution function. Defaults to resolve, and expects the same function signature.

var resolve  = require('glsl-resolve')
var cachedir = __dirname + '/.cache'
var getnpm   = require('npm-file')(cachedir, resolve)

get(package, version, filename, got)

Retrieves a file from npm. Takes the following arguments:

• package: the name of the package on npm.
• version: a semver version range. May also be a fixed version, or * or latest.
• filename: the module in the package to retrieve. Uses the previously defined resolve function, so you can omit file extensions if you so please.
• got(err, path): is called when complete, returning the file path of the target module.
