A very good W3school tutorial can be found here.

Javascript – Node.js Express: Unexpected behavior when calling /newblogs endpoint

This is the code I was working on:

import express from 'express'
import * as blogControler from '../controler/blogControler.js'
import * as authControler from '../controler/authControler.js'

const blogRouter= express.Router()

blogRouter.use(authControler.isVerified)

blogRouter.route('/allblogs').get(blogControler.showallblogs)
blogRouter.route('/:id').get(blogControler.find_blog)
blogRouter.route('/newblogs').get(blogControler.newpost)


export default blogRouter;

When I tried to hit /newblogs endpoint it was throwing error.

I tried many things and finally when I changed the position of /newblogs endpoint it worked!!
The updated code is given below –

import express from 'express'
import * as blogControler from '../controler/blogControler.js'
import * as authControler from '../controler/authControler.js'

const blogRouter= express.Router()

blogRouter.use(authControler.isVerified)

blogRouter.route('/allblogs').get(blogControler.showallblogs)
blogRouter.route('/newblogs').get(blogControler.newpost)
blogRouter.route('/:id').get(blogControler.find_blog)

export default blogRouter;

It is confusing /:id and /newblogs. I noticed that when I was calling /newblogs in the first code snipet it was calling function related to /:id. I think it is confusing the route between /:id and /newblogs.

But why is that happening?

    This is happening beacuse the router interprets a requst to /newblogs as a parameter of /:id, so basicly like someone trying to get a blog with the id of newblogs. As you showed this can be fixed simply by changing the order of the routes.

    This issue due to /:id overwrite /newblog URL because /:id is dynamic URl

    so if you changing the order of the routes you will still get conflict between /:id and /newblog

    so i suggest change /:id URL as below it will solve issue

        import express from 'express'
    import * as blogControler from '../controler/blogControler.js'
    import * as authControler from '../controler/authControler.js'

    const blogRouter= express.Router()

    blogRouter.use(authControler.isVerified)

    blogRouter.route('/allblogs').get(blogControler.showallblogs)

    //route changed
    blogRouter.route('/blogs/:id').get(blogControler.find_blog)
    blogRouter.route('/newblogs').get(blogControler.newpost)
