Question

I am trying to use expressjs in my app.

After installing it using typings install express --ambient --save, I run tsc, but I get two errors:

Answer 1

With Typescript 2.0(https://blogs.msdn.microsoft.com/typescript/2016/09/22/announcing-typescript-2-0/), now it is different:

If you install typescript with the following command:

npm install -g typescript@2.0

You will have to install express typings with command

npm install --save @types/express

Instead of typings getting installed with ambient/global like in earlier releases. The typings get installed in node_modules/@types/express directory

Your package.json will have the following fragment after doing npm install of types :

"dependencies": {
    "@types/express": "^4.0.33"
  }
