An easy way to deploy Yaws applications (Yapps) independently of each other. A Yapp is an Erlang application already installed, by for instance erlmerge.
To register a Yapp on the virtual server uses the command (example):
yapp_handler:add(yapp_handler, "myvirtserverid","/myYappPath", my_app_name)
where "myvirtserverid" is the the "server id" set in the opaque variable yapp_server_id in yaws.conf:
<opaque>
yapp_server_id = myvirtserverid
</opaque>
If Yaws is running on a different node use:
yapp_handler:add({yapp_handler,'node@host'}, "myvirtserverid","/myYappPath", my_app_name)
The default yapp_handler implementation is yapp_server.
The yapp_handler uses the yapp module to change the configuration on Yaws, and the yapp_registry module implementation to store the configuration.
| add/3 | Add a Yapp. |
| add/4 | Add a Yapp. |
| init_yapps/1 | Iinitalizes the Yaws Sconfs list with bootstrap_yapps and Yapps in the the registry. |
| list/2 | Lists all registered Yapps. |
| remove/3 | Remove a Yapp from Yaws. |
add(YappServer::pid(), SrvId::string(), AppName::atom()) -> ok | exit()
Add a Yapp. Adds in the virtual server with the opaque property yapp_server_id = SrvID. The root URL will become "/" ++ atom_to_list(AppName) the Name of the application.
add(YappServer::pid(), SrvId::string(), YappUrl::string(), AppName::atom()) -> ok | exit()
Add a Yapp. Adds in the virtual server with the opaque property yapp_server_id = SrvID. The YappUrl is the root path to the Yapp and the AppName is the Name of the application.
init_yapps(YappServer::pid()) -> ok | exit()
Iinitalizes the Yaws Sconfs list with bootstrap_yapps and Yapps in the the registry. The default name for YappServer is the atom yapp_handler.
list(YappServer::pid(), YawsServerId::SrvId) -> Yapps | exit()
Lists all registered Yapps.
remove(YappServer::pid(), SrvId::string(), YappUrlOrName::string()) -> ok | exit()
Remove a Yapp from Yaws. Removes in the virtual server with yapp_server_id = SrvID. The YappUrlOrName is either the root path to the Yapp or the name of it.
