Dynamic path in express routes
Using middleware is impossible. When a request comes, expressjs will search a registered path first.So here we go why that code not running as well.
For example, I'm as an user request : localhost:2018/test/123
Please following my comment in below
const json = require('./routes.json')const _ = require('lodash')routes.use(function(req, res, next) { let str = req.path let path = str.split('/')[1] // [Request] => /test/123 console.log(path) // [Result] => test let test = _.find(json.routes, function(item) { return item.path.match(new RegExp('^/' + path + '*')) }) console.log(test) //{"path" : "/test/:id", "target" : "localhost:2018", "message" : "This is Test Response" }, //And now, the routes has been registered by /test/:id. //But, you never get response because you was hitting the first request and you need a second request for see if that works. But you can't do a second request, this method will reseting again. Correctmeifimwrong routes.get(test.path, function(req, res) { res.json("Done") })})
How to approach this goal then? However, we need a registering our routes inside app.use
or routes.use
. So far what i got, we can using loop in here.
//Now, we registering our path into routes.use_.find(json.routes, function(item) { routes.use(item.path, function(req, res) { res.json("Done") })})//The result become/** * routes.use('/test:id/', function(req, res, next){ res.json("Done")})routes.use('/hi/', function(req, res, next){ res.json("Done")})*/

Thanks anyway, leave me a comment if there's something wrong with this method :D
