No luck there. Here's my tsconfig 
{
    "compilerOptions": {
      "module": "commonjs",
      "esModuleInterop": true,
      "target": "es6",
      "moduleResolution": "node",
      "sourceMap": true,
      "outDir": "dist",
      "declaration": false,
      "strict": true,
    },
    "lib": ["es2015"]
  }
{
    "compilerOptions": {

    },
    "lib": ["es2015"]
  }

Excuse me, but how exactly do I do that? Sort of new to Express and TS

"Note that CommonJS (cjs) isn't supported. Use ECMAScript Modules (ESM) by setting "type": "module" in your package.json or configuring your tsconfig.json to use ES modules." You cant use commonjs.

@j_slno hello, I changed to modules, and I'm still getting the same errors tsconfig: 
{
    "compilerOptions": {
      "module": "es2015",
      "esModuleInterop": true,
      "target": "es6",
      "moduleResolution": "node",
      "sourceMap": true,
      "outDir": "dist"
    },
    "lib": ["es2015"]
  }
{
    "compilerOptions": {
      "module": "es2015",
      "esModuleInterop": true,
      "target": "es6",
      "moduleResolution": "node",
      "sourceMap": true,
      "outDir": "dist"
    },
    "lib": ["es2015"]
  }
And in package.json I have "type": "module",

Have you tried to delete node_modules and your lock file and reinstall again? lib should be inside compilerOptions also make sure to set declarations to false

@j_slno Thanks for your help. I just created the entire project from scratch, and did some more research, and I finally got the server to run it seems. I do, however have a new issue which is this 
No overload matches this call.
  The last overload gave the following error.
    Argument of type '(req: Request<{}, any, any, ParsedQs, Record<string, any>>, res: Response<any, Record<string, any>, number>) => Promise<Response<any, Record<...>, number>>' is not assignable to parameter of type 'Application<Record<string, any>>'.
      Type '(req: Request<{}, any, any, ParsedQs, Record<string, any>>, res: Response<any, Record<string, any>, number>) => Promise<Response<any, Record<...>, number>>' is missing the following properties from type 'Application<Record<string, any>>': init, defaultConfiguration, engine, set, and 63 more.ts(2769)

Try assign types from express import {Request, Response} from 'express'; then use (req:Request,res:Response)

Just solved the issue. Was using express 4 but express types 5, and apparently they are not compatible
