Write procedural style code that does async in the background
Write procedural style code that runs asynchronously. It may look synchronous, but it's not!
var Bernhard = require'procedural-async';var models = require'./models';Bernhardasynctry// Not needed now, don't block.var current_user = modelsUserretrieveByNamereqsessionusername;var genre = modelsGenreretrieveByNamereqquerygenre;// Will wait on results.var book_results = modelsBooksearchgenre: genreid;var favorite_book_ids = current_userretrieveFavoriteBookIds;var response_data = book_resultsmapreturnid: bookidtitle: booktitleauthor: bookretrieveAuthornameis_favorite: favorite_book_idsindexOfbookid > -1;;catch ereturn nexte;resjsonresponse_data;;
Under the hood, node-procedural-async uses a combination of Proxies and node-fibers. When you call Bernhard.generate, a proxy class is dynamically generated, instanciated and returned. All calls to the proxy will yield until whatever asynchronous task you started has completed. The asynchronous/synchronous magic comes from fibers, so you must write your procedural-async code inside a function that you pass to Bernhard.async.
Returns an instance that derives from Class. You should return this instance from your asynchronous function immediately.
Call this on the instance you got from Bernhard.generate when your asynchronous function has completed.
Put all your procedural-async code inside a function that you pass to this method. Inside this function, you can try/catch any errors.
