Ser­vice work­ers en­able an ap­pli­ca­tion to run a back­ground process that man­ages some lower-level fea­tures. This can in­clude push no­ti­fi­ca­tions, sync­ing data in the back­ground and even pro­vid­ing an ex­pe­ri­ence for when the de­vice is off­line. The level of con­trol is up to the de­vel­oper.

Ser­vice work­ers have been around for some time on An­droid, but they have also re­cently made the jump over to IOS.

While the fo­cus is on mo­bile de­vices, they also work on desk­top. Now that the ma­jor­ity of vis­i­tors will have ac­cess to the func­tion­al­ity, there is no bet­ter time to start im­prov­ing the ex­pe­ri­ence for users. • w3.org/tr/ser­vice-work­ers-1
