Lazy loading
Locked
 
|
Greetings,
-- I have an app with about 450 screens. I must lazy load them as any particular use usually only uses a dozen or fewer screens but which group they use is case specific. So, I'd like to be able to lazy load screens/functionality. I believe Smalltalk on the desktop has an all-or-nothing image file. I sense that Amber has a similar attitude. This won't work for my use-case. Is there a way to do this with Amber? Thanks! Blake McBride You received this message because you are subscribed to the Google Groups "amber-lang" group.

So, I'd like to be able to lazy load >screens/functionality. I understand. Basically, two main possibilities here - SPA that loads parts of code lazily, or actually different pages served from different urls (which then load only subset of code, but each of them loads Amber, of course). The second is a bit strange, but I am mentioning it for completeness. >I believe Smalltalk on the desktop has an all-or-nothing image file. I Yes. >sense that Amber has a similar attitude. This won't work for my Attitude, yes. Implementation - not completely so. AFAICT most SPAs build a single .js bundle, to load faster. Amber does this as well, with `grunt deploy`. So, what you find problematic, namely, not to have everything bundled and have ability to lazy-load, is IMO not Amber-specific. To be more precise about "image" and Amber - there is no image and code is loaded from .ja files. In depliy scenario mentioned earlier, the whole app is bundled. In development scenario, packages are loaded separately, each from its own file. Amber is, from Javascripter PoV, just a set of AMD libraries. >use-case. >Is there a way to do this with Amber? Lazy-loading in-process is not working atm (https://lolg.it/amber/amber/issues/1197), but if you chose to use Amber, I may look into it, as I often fix Amber issues only after they actually block someone's work. With the above issue fixed, you should be able to load packages programmatically. >Thanks! > >Blake McBride Herby -- You received this message because you are subscribed to the Google Groups "amber-lang" group.

However, code & layout for each page gets lazy-loaded as it Again, IMO, but, aren't good SPAs nowadays using HTML5 history API so they actually do have different URL for each screen (thus looking as if each screen loaded different page, and using this info when doing server-side render)? Amber dev server for example allows such SPAs to be developed by supplying fallback url. >is >requested. > >So, the lazy-load feature of Amber would be required. Will take some time, but I presume it's doable (by initializing every uninitialized package at once). >Thanks for the great system and communicating with me! > >Blake McBride > > > >On Tuesday, May 1, 2018 at 9:48:05 AM UTC-5, Herby wrote: >> >> >> >> On May 1, 2018 4:17:10 PM GMT+02:00, Blake McBride <[hidden email] > >> <javascript:>> wrote: >> >Greetings, >> >> Hi, >> > > > > >> >> >I have an app with about 450 screens.

Thank you very much! Do you have a short overview of how to use it?
