It can vary depending on which gadgets are being rendered. There's no way for an individual gadget to know what libraries other gadgets rendered at the same time need, so the container has to tell each gadget which libraries to use. If you didn't do this, shindig would have to load a different library set for *every* gadget render, resulting in really poor performance. > > 2008/6/26 Chris Chabot <[EMAIL PROTECTED]>: > > Actually what shindig does is it looks at the gadget xml and distills a > list > > of required features (and their dependencies) > > > > loop through all required_and_optional_features: > > if the lib is included in the libs=...:..:.. > > append it to the $external_libs_string > > else > > append the javascript code to $inlined_javascript > > > > echo <script src="/gadgets/js/$external_libs.js"> > > echo $inline_libs > > > > So it's not a 'if their not specified on the url things break' kind of > thing > > at all, why would we make something broken by design ? :-) > > > > It's just a way to specify which libs should be included through an > external > > reference, and which should be inlined into the document. > > > > When in doubt, you can always look at the source, in this case it's in > > src/gadgets/http/GadgetRenderingServlet.php line 154. > > > > -- Chris > > > > On Jun 26, 2008, at 11:50 AM, Kevin Brown wrote: > > > >>> I meant, what if SNS does not provide "libs" param in gadget url inside > >>> iframe. > >>> Shindig still should be able to detect required "libs" since they are > >>> in config.php and can ommit unnecessary features gadget XML requires > >>> when rendering. > >> > >> > >> If you don't provide it, shindig will automatically figure out what to > use > >> -- you'll just get fewer cache hits and overall worse performance. > > > > >
