Angular Service Worker 未在开发模式下注册

Question

I would like to know if it' s possible to test pwa and register the serviceworker during the dev mode ( not production)

As when i make the ng build --prod then launchhttp-server in the dist folder it works fine, but then when i do ng serve without the build it gives me the chrome error: Service Worker failed to register

Are the procedures same on prod and dev ? as with lighthouse, the audit gives me ok on serviceworker on prod but not in dev for the same project

Any helps or links would be appreciate

Thanks

This question is 2 years old but I see it wasn't answered.

You cannot run service worker with ng server. As you mentioned, it works using http-server. This is by design. See Angular documentation here .

However, if you are not testing specific service worker functionality, such as retrieving data from cache if offline, your application will still function using ng serve, including retrieving data via http.
