load-plugin

Load a submodule, plugin, or file. Like Node’s require and require.resolve, but from one or more places, and optionally global too.

Install

npm:

npm install load-plugin

When bundled for the browser, a small file is included to warn that, when any of the below functions are invoked, the action is unsupported.

Use

Say we’re in this project (with dependencies installed):

var load = require('load-plugin')

load.resolve('lint', {prefix: 'remark'})
// => '/Users/tilde/projects/oss/load-plugin/node_modules/remark-lint/index.js'

load.resolve('@babel/function-name', {prefix: 'helper'})
// => '/Users/tilde/projects/oss/load-plugin/node_modules/@babel/helper-function-name/index.js'

load.resolve('./index.js', {prefix: 'remark'})
// => '/Users/tilde/projects/oss/load-plugin/index.js'

load.require('lint', {prefix: 'remark'})
// => [Function: lint]

API

`loadPlugin(name[, options])`

Uses the standard node module loading strategy to require name in each given cwd (and optionally the global node_modules directory).

If a prefix is given and name is not a path, prefix-name is also searched (preferring these over non-prefixed modules). If name starts with a scope (@scope/name), the prefix is applied after it: @scope/prefix-name.

`options`

`options.prefix`

Prefix to search for (string, optional).

`options.cwd`

Place or places to search from (string, Array.<string>, default: process.cwd()).

`options.global`

Whether to look for name in global places (boolean, optional, defaults to whether global is detected). If this is nully, load-plugin will detect if it’s currently running in global mode: either because it’s in Electron, or because a globally installed package is running it.

Note: Electron runs its own version of Node instead of your system Node. That means global packages cannot be found, unless you’ve set-up a prefix in your .npmrc or are using nvm to manage your system node.

Returns

The results of requireing the first path that exists.

Throws

If requireing an existing path fails, or if no existing path exists.

`loadPlugin.resolve(name[, options])`

Search for name. Accepts the same parameters as loadPlugin but returns an absolute path for name instead of requiring it, and null if it cannot be found.
