# JwtSource
This is a Source-like component and with most of our Source components, the
component only needs to be added to the page in order to start the flow and is
meant to be used as such (think 'this is like an `<img />`).
The component will go through the steps of requesting a JWT token from a third
party OAuth provider. `src` should contain the full URL of the authorization
URL for the 3rd party provider including `redirect_uri`. Once the user has
logged into the 3rd party provider the `onchange` event will be fired
containing an event-like object whose data contains the JWT information.
During development you can use the `CONSUL_OIDC_PROVIDER_URL`
environment/cookie value to inject/mock the provider URL of your choice. This
var/cookie value **does not** need the `redirect_uri` parameter adding as that
will be automatically added by the UI . This URL will then be returned by our
mock API when requesting the AuthURL for **all** OIDC AuthMethods.
This component **does not store the resulting JWT**, it only emits it via
its `onchange` argument/event handler. Errors are emitted via the `onerror`
argument/event handler.
```hbs preview-template

<input
oninput={{action (mut this.value) value="target.value"}}

)
(concat '&redirect_uri=' (env 'CONSUL_BASE_UI_URL') '/oidc/callback&response_type=code&scope=openid')
)
)}}

## Arguments
| Argument | Type | Default | Description |
| --- | --- | --- | --- |
| `src` | `String` | | The **full** AuthURL for the 3rd party OIDC provider as provided by Consul (including `redirect_uri`) |
| `onchange` | `Function` | | The action to fire when the data changes. Emits an Event-like object with a `data` property containing the JWT data, in this case the `autorizationStatus`, `autorizationCode`, plus the UI added `provider` name |
