# Module `Eliom`

```ocaml
val set_app_name : string -> unit
```
Set your application name. Use this if you want to make it possible to link your Eliom application statically and to have several Eliom applications on the same Web server. See also parameter `?app_names` of `instruction` or `Eliom.run`.

```ocaml
val default_app_name : string
```
The default application name, if you don't specify any

```ocaml
val run : 
  ?app:string ->
  ?xhr_links:bool ->
  ?data_timeout:
    ([< Eliom_common.cookie_level ]
     * Eliom_common_base.scope_hierarchy option
     * float option) ->
  ?service_timeout:
    ([< Eliom_common.cookie_level ]
     * Eliom_common_base.scope_hierarchy option
     * float option) ->
  ?persistent_timeout:

```
`run ?app ()` run Eliom application `app` under current site. Use this to build a static executable without configuration file. Default value of `?app` is `default_app_name`. Other optional values correspond to Eliom configuration for this site.

When `?enable_wasm` is set to `true`, the server will generate a detection script that loads the WASM version of your client code if the browser supports WebAssembly, with automatic fallback to JavaScript otherwise. If not specified, the global default is used (see [`Eliom_config.set_enable_wasm`](./Eliom_config.md#val-set_enable_wasm)), which is `false`.
