Closes #42

Can you please add type: module in package.json, this would also require changes to be made in tsconfig.
Here is a link to the TS docs that can help: ECMAScript modules in Node.js

type: module

Tried this change, getting the error

app.ts(3,28): error TS2792: Cannot find module './middlewares'. Did you mean to set the 'moduleResolution' option to 'node', or to add aliases to the 'paths' option?

which requires all module imports to be explicitly imported with .js extension. Any idea around this?

Or can we merge the changes in the current PR first if the type module changes are not a blocker?
