I’m trying to figure out the best way to register a handlebars helper for my Discourse plugin.
I have an ajax call in my initializer that determines whether the currentUser is part of a particular group. If they are, then they get an extra nav item.
I wanted to do something like this in my hbs file for the nav:
```
{{#if customHelper}}
//show nav item
{{/if}}
```
My other theories on how to do this:
1. Keep the logic in the initializer and use jquery to append the item to the nav.
2. Create a component for the nav item to only be displayed given the aforementioned logic.
So do you think registering a helper is the best to go, if so how? Or are one of my other approached better.
Thanks for any help or advise!

What would `customHelper` do? Can’t you just do something like this instead?
in your initializer
```js
export default {
initialize(container) {
const user = container.lookup('current-user:main');
Discourse.ajax("/some-url").then(result => user.set("isPartOfParticularGroup", true));
}
}
```
and in your `.hbs` file
```handlebars
{{#if currentUser.isPartOfParticularGroup}}
// your stuff
{{/if}
```

このトピックを掘り起こすのは申し訳ありませんが、私の質問にぴったり当てはまります。
プラグインを作成せずにヘルパーを登録することは可能でしょうか？例えば、テーマの HTML の head または body セクションにあるスクリプトからなどです。
ご回答をよろしくお願いいたします！

はい、通常は[テーマコンポーネント](https://meta.discourse.org/t/developer-s-guide-to-discourse-themes/93648)を使用してそれを行います。
