How do I correctly upgrade angular 2 (npm) to the latest version? - npm

Question

Recently I started Angular 2 tutorial at https://angular.io/docs/ts/latest/tutorial/.
and left off with Angular 2 beta 8.
Now I resumed the tutorial and latest beta is beta 14.
If I simply do npm update a few modules (preloaded with the tutorial) are updated but not Angular2 (I can see that with npm ls).
If I do npm update angular 2 or npm update angular2#2.0.0beta.14 it just does nothing either.

Answer 1

The command npm update -D && npm update -S will update all packages inside package.json to their latest version, according to their defined version range. You can read more about it here.
If you want to update Angular from a version prior to 2.0.0-rc.1, then you'll need to manually edit package.json, as Angular was split into several npm modules. Without this, as angular2 package points to 2.0.0-beta.21, you'll never get to use the latest version of Angular.
A list with some of the most common modules that you'll need to get started can be found in the quickstart repository.
Notes:
A cool way to stay up to date with your packages' latest version is to use npm outdated which shows you all outdated packages together with their wanted and latest version.
The reason why we need to chain two commands, npm update -D and npm update -S is to overcome this bug until it's fixed.

Answer 2

Another nice package which I used for migrating form a beta version of Angular2 to Angular2 2.0.0 final is npm-check-updates
It shows the latest available version of all packages specified within your package.json. In contrast to npm outdated it is also capable to edit your package.json, enabling you to do a npm upgrade later.
Install
sudo npm install -g npm-check-updates
Usage
ncufor display
ncu -u for re-writing your package.json

Upgrade to latest Angular 5
Angular Dep packages:
npm install #angular/{animations,common,compiler,core,forms,http,platform-browser,platform-browser-dynamic,router}#latest --save
Other packages that are installed by the angular cli
npm install --save core-js#latest rxjs#latest zone.js#latest
Angular Dev packages:
npm install --save-dev #angular/{compiler-cli,cli,language-service}#latest
Types Dev packages:
npm install --save-dev #types/{jasmine,jasminewd2,node}#latest
Other packages that are installed as dev dev by the angular cli:
npm install --save-dev codelyzer#latest jasmine-core#latest jasmine-spec-reporter#latest karma#latest karma-chrome-launcher#latest karma-cli#latest karma-coverage-istanbul-reporter#latest karma-jasmine#latest karma-jasmine-html-reporter#latest protractor#latest ts-node#latest tslint#latest
Install the latest supported version used by the Angular cli (don't do #latest):
npm install --save-dev typescript#2.4.2
Rename file angular-cli.json to .angular-cli.json and update the content:
{
"$schema": "./node_modules/#angular/cli/lib/config/schema.json",
"project": {
"name": "project3-example"
},
"apps": [
{
"root": "src",
"outDir": "dist",
"assets": [
"assets",
"favicon.ico"
],
"index": "index.html",
"main": "main.ts",
"polyfills": "polyfills.ts",
"test": "test.ts",
"tsconfig": "tsconfig.app.json",
"testTsconfig": "tsconfig.spec.json",
"prefix": "app",
"styles": [
"styles.css"
],
"scripts": [],
"environmentSource": "environments/environment.ts",
"environments": {
"dev": "environments/environment.ts",
"prod": "environments/environment.prod.ts"
}
}
],
"e2e": {
"protractor": {
"config": "./protractor.conf.js"
}
},
"lint": [
{
"project": "src/tsconfig.app.json",
"exclude": "**/node_modules/**"
},
{
"project": "src/tsconfig.spec.json",

{

}
],
"test": {
"karma": {
"config": "./karma.conf.js"
}
},
"defaults": {
"styleExt": "css",
"component": {}
}
}

UPDATE:
Starting from CLI v6 you can just run ng update in order to get your dependencies updated automatically to a new version.
With ng update sometimes you might want to add --force flag.
If you do so make sure that the version of typescript you got
installed this way is supported by your current angular version,
otherwise you might need to downgrade the typescript version.
Also checkout this guide Updating your Angular projects
For bash users only
If you are on are on Mac/Linux or running bash on Windows(that wont work in default Windows CMD) you can run that oneliner:
npm install #angular/{animations,common,compiler,core,forms,http,platform-browser,platform-browser-dynamic,router,compiler-cli}#4.4.5 --save
yarn add #angular/{animations,common,compiler,core,forms,http,platform-browser,platform-browser-dynamic,router,compiler-cli}#4.4.5
Just specify version you wan't e.g #4.4.5 or put #latest to get the latest
Check your package.json just to
make sure you are updating all #angular/* packages that you app is relying on
To see exact #angular version in your project run:
npm ls #angular/compiler or yarn list #angular/compiler
To check the latest stable #angular version available on npm run:
npm show #angular/compiler version

Answer 5

Official npm page suggest a structured method to update angular version for both global and local scenarios.
1.First of all, you need to uninstall the current angular from your
system.
npm uninstall -g angular-cli
npm uninstall --save-dev angular-cli
npm uninstall -g #angular/cli
2.Clean up the cache
npm cache clean
EDIT
As pointed out by #candidj
npm cache clean is renamed as npm cache verify from npm 5 onwards
3.Install angular globally
npm install -g #angular/cli#latest
4.Local project setup if you have one
rm -rf node_modules
npm install --save-dev #angular/cli#latest
npm install
Please check the same down on the link below:
https://www.npmjs.com/package/#angular/cli#updating-angular-cli
This will solve the problem.

Answer 6

Alternative approach using npm-upgrade:
npm i -g npm-upgrade
Go to your project folder
npm-upgrade check
It will ask you if you wish to upgrade the package, select Yes
That's simple

Answer 7

If you want to install/upgrade all packages to the latest version and you are running windows you can use this in powershell.exe:
foreach($package in #("animations","common","compiler","core","forms","http","platform-browser","platform-browser-dynamic","router")) {
npm install #angular/$package#latest -E
}
If you also use the cli, you can do this:
foreach($package in #('animations','common','compiler','core','forms','http','platform-browser','platform-browser-dynamic','router', 'cli','compiler-cli')){
iex "npm install #angular/$package#latest -E $(If($('cli','compiler-cli').Contains($package)){'-D'})";
}
This will save the packages exact (-E), and the cli packages in devDependencies (-D)

Answer 8

Just start here:
https://update.angular.io
Select the version you're using and it will give you a step by step guide.
I recommend choosing 'Advanced' to see all steps. Complexity is a relative concept - and I don't know whose stupid idea this feature was, but if you select 'Basic' it won't show you all steps needed and you may miss something important that your otherwise 'Basic' application is using.
As of version 6 there is a new Angular CLI command ng update which intelligently goes through your dependencies and performs checks to make sure you're updating the right things :-)
The steps will outline how to use it :-)

Answer 9

npm uninstall --save-dev angular-cli
npm install --save-dev #angular/cli#latest
ng update #angular/cli
ng update #angular/core --force
ng update #angular/material or npm i #angular/cdk#6
#angular/material#6 --save
npm install typescript#'>=2.7.0 <2.8.0'

Answer 10

Best way to do is use the extension(pflannery.vscode-versionlens) in vscode.
this checks for all satisfy and checks for best fit.
i had lot of issues with updating and keeping my app functioining unitll i let verbose lense did the check and then i run
npm i
to install newly suggested dependencies.

Answer 11

If you are looking like me for just updating your project to the latest these is what works form me since Angular 6:
Open the console on your project folder: If you type: ng update then you will get the below message:
We analyzed your package.json, there are some packages to update:
Name Version Command to update
--------------------------------------------------------------------------------
#angular/cli 7.0.7 -> 7.2.2 ng update #angular/cli
#angular/core 7.0.4 -> 7.2.1 ng update #angular/core
There might be additional packages that are outdated.
Run "ng update --all" to try to update all at the same time.
So I usually go straight and do:
ng update --all
Finally you can check your new version:
ng version
Angular CLI: 7.2.2
Node: 8.12.0
OS: win32 x64
Angular: 7.2.1
... animations, common, compiler, compiler-cli, core, forms
... http, language-service, platform-browser
... platform-browser-dynamic, router
