# frontpage (name pending)
The front page of your self-hosted server.
This app fits the use case of having multiple applications with access gated by
an OIDC provider, and showing a user what applications they have access to.
## Usage
```sh
frontpage -c CONFIG.TOML
```
where a minimal config file looks like:
```toml
[oidc]
client_id = "some_id"
client_secret = "some_secret"
issuer = "https://auth.example.com/oauth"
scopes = [ "groups" ]
```
Applications are defined using the `apps` keys:
```toml
[apps.login]
name = "Login portal"
url = "https://auth.example.com"
description = "Update your user details"
groups = [ "users" ]
```
In this example, only users whose OIDC groups claim includes `users` will be
allowed to see a link to the login portal. Protection of the link, should a user
gain access to it otherwise, is expected to be done externall (e.g., via an
ingress controller).
