router sample

const crud = require("../controllers/reuseCRUD");
module.exports = (app) => {
  const db = require("../models");
  app.use("/api/customers", crud(db.customers));

It's very convenient and inituitive to tag and edit later. Just add comment above each apis or create seperate documents for comments.
