[Solved] Nodejs/Express: Unresolved function or method

Hello,

just downloaded latest Webstorm Version and created new empty Project.

After creation i executed: npm init --yes

Added express as dependency in package.json and executed: npm install
Then i've copied this example: https://expressjs.com/en/starter/hello-world.html

I can execute the code but Webstorm shows me this Error:

 

How can I fix this "error"? I have same issues with pg package

 

BR

The problem is that these properties are not defined in Express module - they are added dynamically in runtime. That's why WebStorm can't resolve them using static analysis.

Installing express typings (@types/express) should make things better: hit Alt+Enter on "express" in require('express'), choose Install Typescript definitions for better type information.
