How can I use lodash inside my plugin client side script?

[marcelo-lopes]

Hi,

I'm new with nodeBB and I'm writing my first plugin.
I have a question that may be simple but I just can't figure out how to use lodash or underscore inside my client side JS file.

I have the file loaded, since I put this into plugin.json:

"scripts": [
    "client/index.js"
  ],

So in my index.js file:

...
define('forum/client/plugins/my-plugin', [], function () {
    'use strict';
    require(['require', 'lodash'], function (require) {
        var _ = require('lodash');

        var Edit = {};

        Edit.init = function () {
            // an exemple code from lodash usage
            _.map([4, 8], function(n) {
                return n * n;
            });
        };
...

Can someone please point me to how to use lodash on my client side scripts?

Thanks

That's close. You would actually just put it in your define call.

define('forum/client/plugins/my-plugin', ['lodash'], function (_) {
    var Edit = {};

    Edit.init = function () {
        // an exemple code from lodash usage
        var test = _.map([4, 8], function(n) {
            return n * n;
        });

        console.log(test);
    };

    return Edit;
});

Assuming 'lodash' is a url to lodash.js

That's great. Thanks @yariplus!

@marcelo-lopes you can also define modules in plugin.json that can be required directly like define('thing', ['lodash'] instead of specifying the full url.

ahh nice! Thanks @PitaJ
I could not find any info on the docs:
https://docs.nodebb.org/en/latest/plugins/create.html

will give it a try.

Thanks
