package.json in the npm package has unwanted IVY metadata

[monstrege]

Hi,

I finally figured what a bug I was experiencing since a few days was.

I was getting this when I was trying to ng build --prod with ivy in angular 8 :

ERROR in The ngcc compiler has changed since the last ngcc build.
Please completely remove `node_modules` and try again.

which I did many times without success...

I finally found out that the culprit was the ngx-permission package.json that has some ivy compiler metadata inside.

Especially this part:

"__processed_by_ivy_ngcc__": {
    "fesm2015": "8.0.0",
    "typings": "8.0.0",
    "fesm5": "8.0.0",
    "es2015": "8.0.0",
    "esm2015": "8.0.0",
    "esm5": "8.0.0",
    "module": "8.0.0"
  },

This part should just be local data, and not be something included in the npm package. (from my too small knowledge about it)

I'm not blaming anyone here :)

I just don't think that the ivy compiler should change the file and add some garbage metadata inside the package.json like that.

Can anyone remove the __processed_by_ivy_ngcc__ part from the npm package?

Thanks alot!

Temporary workaround is to change

"__processed_by_ivy_ngcc__": {
    "fesm2015": "8.0.0",
    "typings": "8.0.0",
    "fesm5": "8.0.0",
    "es2015": "8.0.0",
    "esm2015": "8.0.0",
    "esm5": "8.0.0",
    "module": "8.0.0"
  }

and put your active angular version. 8.0.3 in my case at the moment.

This is located in ./node-modules/ngx-permissions/package.json

@monstrege Hi thank You. I will look into it but just to be honest ivy is kinda broken on 8 hopefully will be fixed :-)

@monstrege - if you were deleting the node_modules folder and reinstalling the ngx-permissions package, why did it still contain the ngcc marker data? Are you saying that the published file contains these markers?

[petebacondarwin]

Oh I see that the published package.json file does indeed have these markers!!
https://unpkg.com/ngx-permissions@7.0.2/package.json

[AlexKhymenko]

@petebacondarwin i have rebuild with newest version but its still contains markers

"module_ivy_ngcc": "__ivy_ngcc__/fesm5/ngx-permissions.js",
  "__processed_by_ivy_ngcc__": {
    "module": "8.1.0",
    "typings": "8.1.0"
  } 

Using angular cli 8.1.0
ang angualr 8.1.0

is it ok?? Or i should change something?

[petebacondarwin]

Don't run ivy-ngcc on the code that you publish. ngcc is a tool for consumers of your library to use.

[petebacondarwin]

There should be no such markers in the package.json files that you publish to npm.

[AlexKhymenko]

@petebacondarwin Thank You now i understand. When im creating new version it doesn't have ngcc markers. But then im testing that everything works fine in the app and on this moment its adding this markers.

[AlexKhymenko]

@monstrege Fix in version 7.0.3 Please can You verify if everything is ok :-) Reopen the issue if there is a problem please :-)

[petebacondarwin]

Cool!

[monstrege]

@AlexKhymenko Thx!
Also, I believe that those tags will be ok when ivy will work, but not at the moment.
EDIT:
It works well now :)
