Initial setup. Electron app error.

Trying to run initial setup.

npm install -g @nrwl/schematics
npm install -g @angular/cli
create-nx-workspace apps-xplat

npm install @nstudio/schematics --save-dev
ng g xplat --prefix=foo --platforms=web,nativescript,ionic,electron,nest
ng g app devops
ng g app.electron devops --target=web-devops

All good until this point. But after npm i error appear.

Something related to fsevents and node 11.7 I guess. These lines are interesting I think:

In 7.3.1 I updated electron to latest v4 and ended up ensuring @angular/http is at least installed to avoid the need of using ELECTRON_BUILDER_ALLOW_UNRESOLVED_DEPENDENCIES keeping things simpler.

You can now simply run ng update @nstudio/schematics if using angular cli 7.3.x and above. If using previous angular cli version just note this here if using ng update 👍

[NathanWalker]

Ok @ph55 I have a fix for this now and am rolling into an xplat update today which updates all electron dependencies and postinstall. You can simply run ng update @nstudio/schematics now to fix or if you run into trouble with ng update you can make the following manual changes:

Open root package.json and make the following changes:

Add to dependencies

• "@angular/http": "^7.0.0",

We could keep unresolved dep flag on electron but not worth it so just add this.

Modify devDependencies as follows:

    "electron": "^4.0.5",
    "electron-builder": "^20.38.4",
    "electron-rebuild": "~1.8.4",
    "electron-installer-dmg": "~2.0.0",
    "electron-packager": "~13.1.0",
    "electron-reload": "~1.4.0",
    "electron-store": "~2.0.0",
    "electron-updater": "~4.0.6",

That updates all electron dependencies and importantly adds electron-rebuild.

Modify scripts as follows:

"postinstall": "electron-rebuild install-app-deps",

Now modify your electron app apps/electron-devops/tsconfig.json as follows:

• Add "types": ["jasmine"], so it should look like this:

{
  "compilerOptions": {
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "esModuleInterop": true,
    "target": "es5",
    "types": ["jasmine"],
    "typeRoots": ["../../node_modules/@types"],
    "lib": ["es2017", "es2016", "es2015", "dom"]
  },
  "include": ["src/index.ts"]
}

That’s needed to prevent jest types from colliding with jasmine as mentioned here.

Now clean and reinstall your workspace:

npm cache clean --force   // for good measure!
rm -rf node_modules package-lock.json 
npm i

You should now be able to run all apps including your electron app with:

npm run start.electron.devops

Lemme know if that gets you going and thanks for reporting this 👍
