How to fix “Task is not in your gulpfile” error when using npm link?

Question

We have a bunch of applications sharing common gulp logic, so we made a gulp plugin that contains a bunch of custom tasks.

However we\'d like to avoid installing gulp+o

Answer 1

Alternatively to the accepted answer, you can do it the way that was popular in grunt times, where you inject gulp to the plugin:

In plugin: wrap everything with:

module.exports = function(gulp) {
    gulp.task('foo', function () {
        ...
    })
    ...
}

and remove require('gulp') from the plugin's file.

In gulpfile that depends on plugin you then do:

var gulp = require('gulp');
require('my-gulp-plugin')(gulp)

That way

• you can have multiple plugins in the main gulpfile, because you don't override gulp.tasks.
• plugins don't have to declare gulp a package.json dependency in each of the plugins (less work for npm install)

Answer 2

Figured it out. Added the following line at the bottom of my module:

module.exports = gulp;

And my gulpfile in each module looks like this:

var gulp = require('gulp'); 
var mygulpplugin = require('mygulpplugin');
gulp.tasks = mygulpplugin.tasks;
