Legacy Peer Deps Issue

[IbrahimAyed1]

I got a Legacy peer deps error while running npm install, there's incompatibility in the versions :

 @angular/common@"^19.0.0" from @ngrx/data@19.
 npm ERR!   @ngrx/data@"^19.2.1" from the root project

 peer @angular/common@"^19.0.0" from @ngrx/data@19.2.1
 npm ERR!   node_modules/@ngrx/data
 npm ERR!     @ngrx/data@"^19.2.1" from the root project 

i just used --legacy-per-deps.

Also while I am using v18 as mentioned in the doc i couldn't run npm run start and needed to switch to v22 to run.

Also while I am using v18 as mentioned in the doc i couldn't run npm run start and needed to switch to v22 to run.

It was solved by making these updates to package.json & deleting package.lock.json
@ngrx/{store,effects,entity,router-store,store-devtools,data,operators,schematics} → ^20.0.0
rxjs → ^7.8.1

then npm i.
nodejs version used : v22.18.0
