gulp-load-plugins
Loads gulp plugins from package dependencies and attaches them to an object of your choice.
Node Version Requirements
Due to the native support of ES2015 syntax in newer versions of Node, this plugin requires at least Node v8. If you need to maintain support for older versions of Node, version 1.6.0 of this plugin is the last release that will support Node versions less than 8.
Install
NPM:
$ npm install --save-dev gulp-load-plugins
Yarn:
$ yarn add -D gulp-load-plugins
Usage
Given a package.json
file that has some dependencies within:
{
"dependencies": {
"gulp-jshint": "*",
"gulp-concat": "*"
}
}
Adding this into your Gulpfile.js
:
const gulp = require('gulp');
const gulpLoadPlugins = require('gulp-load-plugins');
const plugins = gulpLoadPlugins();
Or, even shorter:
const gulp = require('gulp');
const plugins = require('gulp-load-plugins')();
Will result in the following happening (roughly, plugins are lazy loaded but in practice you won't notice any difference):
plugins.jshint = require('gulp-jshint');
plugins.concat = require('gulp-concat');
You can then use the plugins just like you would if you'd manually required them, but referring to them as plugins.name()
, rather than just name()
.
This frees you up from having to manually require each gulp plugin.
Options
You can pass in an object of options that are shown below: (the values for the keys are the defaults):
gulpLoadPlugins({
DEBUG: false,
pattern: ['gulp-*', 'gulp.*', '@*/gulp{-,.}*'],
overridePattern: true,
config: 'package.json',
scope: ['dependencies', 'devDependencies', 'peerDependencies'],
replaceString: /^gulp(-|\.)/,
camelize: true,
lazy: true,
rename: {},
renameFn: function (name) { ... },
postRequireTransforms: {},
maintainScope: true
});
Multiple config
locations
While it's possile to grab plugins from another location, often times you may want to extend from another package that enables you to keep your own package.json
free from duplicates, but still add in your own plugins that are needed for your project. Since the config
option accepts an object, you can merge together multiple locations using the lodash.merge package:
const merge = require('lodash.merge');
const packages = merge(
require('dep/package.json'),
require('./package.json')
);
const $ = gulpLoadPlugins({
config: packages
});
postRequireTransforms
(1.3+ only)
This enables you to transform the plugin after it has been required by gulp-load-plugins.
For example, one particular plugin (let's say, gulp-foo
), might need you to call a function to configure it before it is used. So you would end up with:
const $ = require('gulp-load-plugins')();
$.foo = $.foo.configure(...);
This is a bit messy. Instead you can pass a postRequireTransforms
object which will enable you to do this:
const $ = require('gulp-load-plugins')({
postRequireTransforms: {
foo: function(foo) {
return foo.configure(...);
}
}
});
$.foo
Everytime a plugin is loaded, we check to see if a transform is defined, and if so, we call that function, passing in the loaded plugin. Whatever this function returns is then used as the value that's returned by gulp-load-plugins.
For 99% of gulp-plugins you will not need this behaviour, but for the odd plugin it's a nice way of keeping your code cleaner.
Renaming
From 0.8.0, you can pass in an object of mappings for renaming plugins. For example, imagine you want to load the gulp-ruby-sass
plugin, but want to refer to it as just sass
:
gulpLoadPlugins({
rename: {
'gulp-ruby-sass': 'sass'
}
});
Note that if you specify the renameFn
options with your own custom rename function, while the rename
option will still work, the replaceString
and camelize
options will be ignored.
npm Scopes
gulp-load-plugins
comes with npm scope support. By default, the scoped plugins are accessible through an object on plugins
that represents the scope. When maintainScope = false
, the plugins are available in the top level just like any other non-scoped plugins.
Note: maintainScope
is only available in Version 1.4.0 and up.
For example, if the plugin is @myco/gulp-test-plugin
then you can access the plugin as shown in the following example:
const scoped = require('gulp-load-plugins')({
maintainScope: true,
});
scoped.myco.testPlugin();
const nonScoped = require('gulp-load-plugins')({
maintainScope: false,
});
nonScoped.testPlugin();
Lazy Loading
In 0.4.0 and prior, lazy loading used to only work with plugins that return a function. In newer versions though, lazy loading should work for any plugin. If you have a problem related to this please try disabling lazy loading and see if that fixes it. Feel free to open an issue on this repo too.
Override Pattern
In 1.4.0 and prior, configuring the pattern
option would override the built-in ['gulp-*', 'gulp.*', '@*/gulp{-,.}*']
. If overridePattern: false
, the configured pattern
will now extends the built-in matching.
For example, both are equivilant statements.
const overridePlugins = require('gulp-load-plugins')({
overridePattern: true,
pattern: ['gulp-*', 'gulp.*', '@*/gulp{-,.}*', 'foo-bar']
});
const extendedPlugins = require('gulp-load-plugins')({
overridePattern: false,
pattern: ['foo-bar']
});
Credit
Credit largely goes to @sindresorhus for his load-grunt-plugins plugin. This plugin is almost identical, just tweaked slightly to work with Gulp and to expose the required plugins.
