Application.cfc

A very basic script example

component {
    this.name = "AppName";
    this.datasource = "AppDataSource";
    this.sessionManagement = true;

    function onApplicationStart() {
        application.config="xyz";
    }

 }

This example uses getCurrentTemplatePath and getDirectoryFromPath to dynamically get the directory that the current Application.cfc resides in and then defines some mappings relative to that. You want to avoid using expandPath in Application.cfc because the path will be relative to the current template path not the Application.cfc path.

component {
    this.name = "AppName";
    this.appBasePath = getDirectoryFromPath(getCurrentTemplatePath());
    this.mappings["/components"] = this.appBasePath & "components";
    this.mappings["/frameworks"] = this.appBasePath & "frameworks";

}

The minimum required to create a WebSocket channel is the name attribute. A channel can also specify a custom channel listener CFC, if not specified the ChannelListener.cfc, available in wwwroot/CFIDE/websocket directory is called (Using Channel Listeners).

Note: Though you can use any number of sub-channels, you do not specify them as they are dynamically created (dot notation). To subscribe to channels you create a WebSocket object using the cfwebsocket tag in your CFM template.

component {
    this.name = "AppName";
    this.wschannels = [{name=channelName, cfclistener=channel_listener_CFC}];
}

This example shows how to map to directories that are a level up from the Application.cfc (web root) as well as how to handle an application that will need to be deployed on multiple operating systems (Mac, Unix, Windows) due to differing developer environments. It uses Find to determine if we need to use forward or back slashes in our paths and ListDeleteAt to drop the current directory from the path. We can then build the path for our mappings and custom tags using this information.

component {
    this.name = "AppName";
    this.currentPath = getDirectoryFromPath( getCurrentTemplatePath() );
    this.delim = find("/", this.currentPath) ? "/" : "\";
    this.basePath = listDeleteAt(this.currentPath, listLen(this.currentPath, this.delim), this.delim);
    this.mappings["/components"] = this.basePath & this.delim & "components";
    this.mappings["/frameworks"] = this.basePath & this.delim & "frameworks";
    this.customtagpaths = this.basePath & this.delim & "customtags";

}
