Update Typescript in Angular2 project

Question

I have an Angular2 project using Typescript, in Visual Studio. I want to update Typescript from 1.8 to 2.0.x. In my system I have updated typescript and tsc -v logs Version 2.0.10 The package.json, among others, contains

"devDependencies": {
    ....
    "typescript": "^1.8.10",
    "typings": "^1.3.1",
    ...
}

In order to update typescript, is it enough to change the version to "typescript": "^2.0.10" in the package.json? Also, what is the relation of typescript and typings version, when it comes to update?

Answer 1

For Exact version

• npm install [email protected] --save-dev

For latest release

• npm install typescript@latest --save-dev

Answer 2

Updating the typescript version in your package.json and running npm install will be enough to upgrade the version you are using for your project.

Typescript 2.x has introduced a new way to manage types, using the @types/... qualifier npm packages - you can still use the typings you have been using before however - but you might wish to update that to the latest version which from npm at the time of writing this answer is 2.0.0
