HMR / Angular CLI and lazy routes

Hi,

is it possible to use HMR with Lazy routes?

HMR works correctly if i change something in “normally” loaded routes (components).

but if i change something in Lazy loaded module, it will refresh the entire page with error:

HMR] Cannot apply update. Need to do a full reload!(anonymous function) @ dev-server.js:33ZoneDelegate.invoke @ zone.js:232Zone.run @ zone.js:114(anonymous function) @ zone.js:502ZoneDelegate.invokeTask @ zone.js:265Zone.runTask @ zone.js:154drainMicroTaskQueue @ zone.js:401 dev-server.js:34 [HMR] Error: A platform with a different configuration has been created. Please destroy it first. at assertPlatform (http://localhost:4200/vendor.bundle.js:27579:15) at http://localhost:4200/vendor.bundle.js:27564:16 at bootstrap (http://localhost:4200/main.bundle.js:273:132) at hmrBootstrap (http://localhost:4200/main.bundle.js:1091:5) at Object.<anonymous> (http://localhost:4200/main.bundle.js:277:90) at Object.494 (http://localhost:4200/main.bundle.js:288:30) at __webpack_require__ (http://localhost:4200/inline.bundle.js:686:30) at hotApply (http://localhost:4200/inline.bundle.js:613:14) at hotUpdateDownloaded (http://localhost:4200/inline.bundle.js:311:13) at hotAddUpdateChunk (http://localhost:4200/inline.bundle.js:291:13)(anonymous function) @ dev-server.js:34ZoneDelegate.invoke @ zone.js:232Zone.run @ zone.js:114(anonymous function) @ zone.js:502ZoneDelegate.invokeTask @ zone.js:265Zone.runTask @ zone.js:154drainMicroTaskQueue @ zone.js:401 dev-server.js:49[HMR] Waiting for update signal from WDS...

But strange is, it wont work if i change something in my “SharedModule” with shared components - across all modules (lazy loaded too)

if (!platform.injector.get(requiredToken, null)) { throw new Error('A platform with a different configuration has been created. Please destroy it first.'); } it will drop (requiredToken is “Platform: browserDynamic”)

I have solution from there: https://medium.com/@beeman/tutorial-enable-hrm-in-angular-cli-apps-1b0d13b80130#.jbftda8bb

Thanks for your work.

Is there any progress regarding this issue?

Please check out this example I’ve put together that shows how to reload lazy-loaded routes and lazy/manual-loaded components. It doesn’t maintain component state, but has really helped our development team increase their speed of local development.
