How to update / upgrade from Angular 4 to Angular 5+

Question

I need to update my project from Angular 4 to Angular 5+ ,

I need to change all following dependencies to Angular 5+.

I also updated Angular CLI to 1.5.0.

I tried to create new project but it seems to create only Angular 4 project.

ng new NG5_Project

"dependencies": {
  "@angular/animations": "^4.2.4",
  "@angular/common": "^4.2.4",
  "@angular/compiler": "^4.2.4",
  "@angular/core": "^4.2.4",
  "@angular/forms": "^4.2.4",
  "@angular/http": "^4.2.4",
  "@angular/platform-browser": "^4.2.4",
  "@angular/platform-browser-dynamic": "^4.2.4",
  "@angular/router": "^4.2.4",
  "core-js": "^2.4.1",
  "rxjs": "^5.4.2",
  "zone.js": "^0.8.14"
}

What am I doing wrong.

CLI Config :

Answer 1

This specific problem was fixed with Node version update.

I had to update Node version,

sudo apt-get install nodejs

npm uninstall -g @angular/cli

npm cache clean

npm install -g @angular/cli@latest

ng new ProjectName

node --version ==> 8.9.0

ng --version ==> 1.5.0

"dependencies": {
    "@angular/animations": "^5.0.0",
    "@angular/common": "^5.0.0",
    "@angular/compiler": "^5.0.0",
    "@angular/core": "^5.0.0",
    "@angular/forms": "^5.0.0",
    "@angular/http": "^5.0.0",
    "@angular/platform-browser": "^5.0.0",
    "@angular/platform-browser-dynamic": "^5.0.0",
    "@angular/router": "^5.0.0",
    "rxjs": "^5.5.2",
    "zone.js": "^0.8.14"
}

Check Angular blog out

https://blog.angular.io/version-5-0-0-of-angular-now-available-37e414935ced

In the article, an update guide is mentioned.

You can find it here: https://angular-update-guide.firebaseapp.com/

Also, you can update your angular-CLI to 1.5.0 which will create angular v5 project. You can compare the differences with yours.

Answer 4

If you want to simply upgrade your angular4 project to angular 5 do the following.

1. Go to your project directory.
2. Open a command prompt and run the following commands
3. npm install -g npm-check-updates
4. ncu -u

This worked for me.
