We have a constructor function for the App <\/strong>prototype, which will use the default configuration as a base, and then replace any base functionality (name, urlTest, appKey, pageKey, db, path, handler). This means that it might be a good idea to get rid of the default app configuration from the configuration files and then include it in this function directly. That would simplify the file structure a little bit and the default app configuration is kind of hidden at the bottom of the file it’s defined in anyways, so that change could be made without too much modification to the current configuration.<\/p>\n\n\n\nAs for the concept of Apps in general, I’ve very tempted to remove this functionality as much as possible as it seems like a better idea to host a single application on a single Jaxer instance and try not to overload Jaxer too much. However in the case of hosting multiple subdomains on the same server, it might actually be useful functionality. <\/p>\n\n\n\n
For the ‘App’ functionality I think it can be minimized and left in for now, as the basic default application that is provided to the user and can be used as-is without changes. And then if this functionality can be taken advantage of in the future, then the ground-work can be there. Though in general I think the main way to take advantage of it is basically to provide a default database implementation for a specific path or URL, so the database connection parameters don’t need to be included under the public directory path.<\/p>\n\n\n\n
Though a very similar effect can be achieved by defining a ‘connect.js’ file that is defined as ‘run-at=server’ and placed in a ‘jaxer-include’ folder where it’s needed. And this would provide almost exactly the same functionality as the concept of what Aptana defined as Apps, that would be a lot more simple and intuitive to use as opposed to having to edit the server configuration for the ‘App’ to be implemented. So in general I think it’s generally a good idea to continue to minimize this functionality. <\/p>\n","protected":false},"excerpt":{"rendered":"
