# useMeta
Adds getters to easily retrieve `` meta value.
Simply list at the top of your controller the list of meta name you need (`static metaNames = []`)
Getters are then automatically defined by the mixin.
- Getter name is a camelized conversion of the meta name with an optional `Meta` suffix. `user_id` becomes `userIdMeta`
- Values are automatically cast so getters return: String, Number, Boolean or Object
**Options:**
| Option| Description | Default value |
|-----------------------|-------------|---------------------|
| `suffix` | prepend or not `Meta` to the getter name. Default is true to remain consistent with `Value` and `Class` API |true|
**Example**
```js
useMeta(this, { suffix: false })
```
## Usage
**Composing**
Given some `` html
```html
...
...
```
```js
import { Controller } from '@hotwired/stimulus'
import { useMeta } from 'stimulus-use'
export default class extends Controller {
static metaNames = ['userId', 'admin', 'email', 'snake_case_name']
connect() {
useMeta(this)
// individual getters
this.userIdMeta // 123456 -> Number
this.adminMeta // true -> Boolean
this.emailMeta // "joe@doe.com" -> String
this.snakeCaseNameMeta // "are camelized"
// get all metas in one object
this.metas
// {
// userId: 123456,
// admin: true,
// email: "joe@doe.com",
// snakeCaseName: "are camelized"
// }
}
}
```
