[jira] [Created] (CB-296) Cordova.hasResouce doesn't work for
Android
Cordova.hasResouce doesn't work for Android
-------------------------------------------
Key: CB-296
URL: https://issues.apache.org/jira/browse/CB-296
Project: Apache Callback
Issue Type: Bug
Components: Android
Affects Versions: 1.5.0
Environment: Android
Reporter: Takashi Okamoto
Assignee: Joe Bowser
I tried Cordova.hasResource with Cordova 1.5.0 snapshot on Android.
I found Cordova.hasResouce doesn't work and not defined in cordova-1.5.0.js
cordova.js.base may not include cordova-1.5.0.js and
it seems build.xml problem.

[jira] [Closed] (CB-296) Cordova.hasResouce doesn't work for

------------------------
Resolution: Won't Fix
Assignee: Filip Maj (was: Joe Bowser)
hasResource is not part of the core API (see the docs).
In 1.5 for the Android implementation, we moved to using the Android build of the Cordova-JS project, a unified JavaScript layer for all Cordova platforms. You can find that project here:
https://github.com/apache/incubator-cordova-js
P.S. hasResource's implementation was literally:
{code:javascript}
function hasResource(res) {
return (window.plugins[res] !== undefined);
}
{code}
... which you can now check by calling require() on a specific plugin and seeing if it returns a truthy value.

[jira] [Commented] (CB-296) Cordova.hasResouce doesn't work for
Android

Patrick Mueller commented on CB-296:
------------------------------------
bq. ... which you can now check by calling require() on a specific plugin and seeing if it returns a truthy value.
calling {{require(<some module name>)}} when the specified module is not available will throw an exception, so ... that's not a good way to check. This should work:
{noformat}
function hasResource(moduleId) {
try {
return require(moduleId)
}
catch(e) {
return false
}
}
{noformat}
But what's the use case here? Maybe this was for a non-core plugin? How do plugins register themselves so that some other piece of code can ask if they're loaded? Do we eventually want to move them into the module system? If so, we may want to add an additional API such as {{cordova.isModuleAvailable(<some module name>)}} which would return a boolean indicating whether a module was available or not. Node.js has an API called {{require.resolve(<some module id>)}}, which resolves a module name to a file name without loading it, but also throws an error if the module isn't available.
