Intellisnese for node.js in WebStorm

I'm having trouble with intellisense in WebStorm for express package and also for sequelize package. I have also tried VS code and problem there is same. For example with imported package

const express = require('express');
const app = express();

then I get no suggestion for app.get() or any other method. Even worst I get the get() method underline in WebStorm with warning saying Unresolved method or function

Code runs fine though. There are also other problems with other packages like sequelize. I kinda managed to fixed express intellisense by adding .application in import which however crash the app

const express = require('express').application;

Another approach I tried was to add enable after initialisation. That doesn't crash the app and intellisense start works even warning is gone

const app = express().enable();

I know this works for others by watching video online. Nobody had to add anything into import or initialisation to make that intellisense work so I guess there is some problem with setting and I just can't figure out what it is

Here are some pictures of my stetting

Solution

  • Adding TypeScript definition files usually helps IDEs to resolve methods that are otherwise hard to resolve based on the static code analysis.

    In WebStorm, you can press Alt-Enter on require('express') and select Install TypeScript definitions for better type information – this will download @types/express and configure it in the IDE. Alternatively, you can add @types/express to your package.json file.
