Question

So I have this simple require:

require(['app/'+url,'dojo/text!content/'+url], function(module,template){
        if(module.init){
                module.init({
                        container: panel, 
                        containerId: 'contentTabs_' + idOp,
                        template: template
                });
        }
});

But the template might not be there (sometimes it does). So whatever happens I’d like my require callback to be executed.

What is the AMD way to do this?

Thanks guys.

Instead of using dojo/text!, write your own plugin:

require(['foo/maybe!'+url], function(maybeTemplate) {
  if (maybeTemplate === undefined) {
    // it's there
  } else {
    // it's not there
  }
}

foo/maybe must resolve to an object with a load : function (id, require, callback) member.

load(
  id,        // the string to the right of the !
  require,   // AMD require; usually a context-sensitive require bound to the module making the plugin request
  callback   // the function the plugin should call with the return value once it is done
) -> undefined

You can use an XHR call to fetch the resource and resolve to undefined on a 404 error.
