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.
