Error due to reference to types core-js about in-memory-web-api HOT 13 CLOSED

error appears since "angular-in-memory-web-api": "0.1.14"

try to replace with "angular-in-memory-web-api": "0.1.13" in package.json

fix pb for me

from in-memory-web-api.

I think we fixed in v.0.1.16

from in-memory-web-api.

The problem seems to come from the line /// <reference types="core-js" /> of in-memory-backend.service.d.ts.
I don't know the utility of this line but its deletion seems to fix the problem.

from in-memory-web-api.

Yeah, removing it fix the problem...

But the problem is worse than I though, because it cause an error during the ng serve --aot true and a corrupted build with ng build --aot true.

I experienced the same issue with missing core-js typings after upgrading an angular-cli beta.18 project to beta.19-3. Thx @cqst. for now, reverting back to "angular-in-memory-web-api": "0.1.13" fixed the issue.

Downgrading to .18 did not help (re: ng-lightning/ng-lightning#265)

ᐅ rm node_modules -Rfv
ᐅ yarn install
ᐅ ng version
angular-cli: 1.0.0-beta.18
node: 7.1.0
os: linux x64
ᐅ ng build
(...)
Error in bail mode: [default] /(...)/node_modules/ng-lightning/config/config.d.ts:1:0 
Cannot find type definition file for 'core-js'.
(...)

workaround by removing the core-js reference from the affected dependencies (ng-lightning in my case) could be verified.

I had the same issue...

My environment:

angular-cli: 1.0.0-beta.19-3
node: 6.8.1
os: win32 x64

Steps to fix Tour of Heroes with angular-cli (in my case):

1 - npm i angular-in-memory-web-api
2 - npm i @types/core-js
3 - Edit package.json file and add the dependency: angular-in-memory-web-api": "0.1.14"
4 - On tsconfig.json, change lib settings to: "lib": ["es5", "dom"],

Downgrading to "angular-in-memory-web-api": "0.1.13" worked fine

from in-memory-web-api.

Issue is in file:

node_modules/angular-in-memory-web-api/in-memory-backend.service.d.ts

Just remove:
/// <reference types="core-js" />

and all will work fine.

This is sooooo fragile solution so don't use in production !!!

Downgrading to 0.1.13 until this pretty critical bug is fixed.

from in-memory-web-api.

@wardbell Could this bug be fixed please (removing the offending line at detailed above)?

from in-memory-web-api.

I've proposed a PR ( #65 ) to do that, but no one merge it... 😢

from in-memory-web-api.

Yes, I have this issue also. Please merge #65. Thanks!

from in-memory-web-api.

FYI, if this is an urgent issue for anyone and you don't want to wait for #65 to get merged, you can just create your own fork of this repo, apply the fix yourself, and use your forked repo in your package.json until #65 (or some other fix) does get merged. That's what I did.
