Re: [tw] Re: TW5 node.js Running out of memory
I've got the basics of lazy loading working natively with TW5 for 5.0.8 with a demo that lazily loads images, but treats other tiddlers normally. The images are still being loaded as base64 data URIs, rather than referencing the image files directly on the server. But it still seems to work pretty well.

Re: [tw] Re: TW5 node.js Running out of memory
Hi Dave Lazy loading just applies to the client-server edition - it is in effect a refinement of the interface between the browser and server, so it's the two components acting in concert.

Re: [tw] Re: TW5 node.js Running out of memory
Hi Dave It's actually not Node.js that's running out of memory here, it's the browser. It's not normal behaviour, though, and I've not seen anything like this reported before. It's certainly not something that's associated with running Node.js. You say that you've got 2000 tiddlers in there with many images, perhaps it's just that you're generating a sufficiently large TW file to confuse the browser. If you save the wiki as a standalone HTML file, how big is it? tiddlywiki --rendertiddler $:/core/save/all index.html text/plain Another possibility is that you've inadvertently set up an infinite loop - TW tries to protect you from circular transclusion, but if you somehow managed it, the symptom would likely be an out of memory error.

Re: [tw] Re: TW5 node.js Running out of memory
Hi Dave At the moment, running under Node.js is more about having the convenience of managing your tiddlers as individual files. When a TW is built it includes a representation of all tiddlers, whether it is built for serving to the browser via tiddlywiki --server, or built as a standalone HTML file. The reason that Firefox is crashing is because all of those images are packed into the TiddlyWiki file as base64 tiddlers. Unpacking and displaying them will be much less efficient than working with an ordinary independent image file. TiddlyWiki5 does support lazy loading, where the original TiddlyWiki file is built with skinny tiddlers that omit the body, but include the metadata (tags etc), and then the body is loaded on demand. Lazy loading is currently only implemented when running on TiddlyWeb/TiddlySpace, but the plan is to support it natively too. What's needed is a way of specifying tiddlers within a wiki folder that should be served skinny. For example, a new filter operation like [is[image]]. For better performance with images, it would be useful to be able to render images as ordinary img src=... tags, rather than base64. I'll investigate some quick hacks that will get things working for you, Best wishes Jeremy On Tue, Jan 28, 2014 at 7:27 PM, David Gifford dgiff...@crcna.org wrote: Still trying to drive trucks over your bridges, Jeremy!

Re: [tw] Re: TW5 node.js Running out of memory
Hi Jeremy, Last question, I promise! If you wanted to store images online and not have those images inaccessible to the public and searches, yet use a TiddlyWiki to access them, what would you do to set it up?

That's cool :) Did you optimize your images, to be used with your app? eg: they have a resolution, that is good enough to be displaied in a browser, but the browser dosn't need to resize them.
