How to configure dynamic routes with express.js

Question

I have a route.js which looks like this:

module.exports = function(app) {

  app.get(\'/tip\', function(req, res) {
    res.render(\"tip\");
  });

  app.get

There are many ways to implement dynamic express routes. It depends to a great extent on the structure you have implemented in your project, here I leave an example of dynamic routes and I hope it will be useful.

RouterService.js

module.exports = (function(myCustomRoutes) {
   let express = require('express');
   let router  = express.Router();
   let methods = Object.keys(myCustomRoutes); // getting methods ('get', 'post'... etc)
   let routesMethod = null;
   let url = null;

   for(i in methods) {
      routesMethod = Object.keys(myCustomRoutes[methods[i]]);
      for(j in routesMethod) {
         url = '/' + routesMethod[j];
         url += '/:' + myCustomRoutes[methods[i]][routesMethod[j]].params.join('/:');console.log(url);
         router[methods[i]](url, myCustomRoutes[methods[i]][routesMethod[j]].controller);
      }
   }

   return router;
})();

CustomRoutes.js

module.exports = (function() {
    let routes = {get: {}, post: {}};
    let routerService = require('./RouterService');

    // GET:  /dynamic1
    routes.get.dynamic1 = {
       params: [],
       controller: function(req, res, next) {
           res.send('route 1');
       }
    };

    // GET:  /dynamic2/:param1
    routes.get.dynamic2 = {
       params: [':param1'],
       controller: function(req, res, next) {
           res.send('route 2');
       }
    };
    // POST: /dynamic3/:param1/:param1
    routes.post.dynamic3 = {
       params: ['param1', 'param2'],
       controller: function(req, res, next) {
          res.send('route 3');
       }
    };

    /*
    *  Export a router with paths
    *  GET:  /dynamic1
    *  GET:  /dynamic2/:param1
    *  POST: /dynamic3/:param1/:param1
    **/
    return routerService(routes);
})();

app.js

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


/*
 *  Option 1
 *  GET:  /dynamic1
 *  GET:  /dynamic2/:param1
 *  POST: /dynamic3/:param1/:param1
 **/
 app.use(require('CustomRoutes')());


/*
 *  Option 2
 *  GET:  /api/v1/dynamic1
 *  GET:  /api/v1/dynamic2/:param1
 *  POST: /api/v1/dynamic3/:param1/:param1
 **/
 app.use('/api/v1', require('CustomRoutes')());
