javascript - angular2 work in background thread with custom serializable objects -


how achieve this: have potentially long computation (eg. huge json parse http resp.) , want in non-blocking way.

i tried adopt multithread.js lib background work using web worker. lib requires json serializable objects pass execution function not aware of closures, dom or other globals. eg. mt.process(longrunningjob, donecallback)(jsonserializableargforbgjob). lib rather old (3 years ago last commit). there better alternatives more suitable angular2? need target widest range of browsers including older ones (except ie/edge) service worker or lib using not option.

for serialization found cerialize lib serialize custom objects decorating props. work adds quite lot of code , seems error prone. other concern use inheritance , polymorphism , not sure if lib ready such uc. 1 expect mechanism known java: serializable interface , overriden serialize/deserialize methods. there way accomplish in typescript/angular2?

take @ vkthread plugin or on angular version ng-vkthread

with plugin can download data directly in thread, process , return result in ui.

doc , live demo vkthread

doc , live demo ng-vkthread

please let me know if have questions.
