I have created a folder testint
My testint/app.js having following code
const express = require('express'); const path = require('path');
const bodyParser = require('body-parser'); const cors = require('cors');
const passport = require('passport'); const mongoose = require('mongoose');
const app = express(); const port = 7000; app.use(cors());
app.use(bodyParser.json());
app.use('/users', users); //Not working
app.get('/',(req,res) => {
res.send("Invalid Endpoint");
});
app.listen(port, () =>{
console.log('Server started on port '+ port);
});
testint/routes/users.js contains :
const express = require('express'); const router = express.Router();
res.send('Authenticate');
router.get('/register',(req, res, next) => {
res.send('REGISTER');
});
module.exports = router;
If I run http://localhost:7000/users/register
Am getting :
Cannot GET /users/register
I dint know where am wrong and am new to node any help will be appreciated.
I got solution. I didn't include
const users = require('./routes/users');
in app.js
and res.send('Authenticate'); in users.js is not required for instance.

My index.js file:
//Dependencies
const express = require('express');
const cors = require('cors');
const bodyParser = require('body-parser');
const posts = require('./routes/api/posts.js');
//Configuration
const port = process.env.PORT || 5000;
//App object
const app = express();
//Middleware
app.use(bodyParser.json());
app.use(cors());
//Main app
app.use('api/posts',posts);
//Starting server
app.listen(port,()=>{
console.log(`server running at ${port}`);
});
My Api file:
//Dependencies
const express = require('express');
const mongodb = require('mongodb');
//Mini app
const router = express.Router();
//Get post
router.get('/',(req,res)=>{
res.send('hello');
});
//Add post
//Delete post
module.exports = router;
I'm expecting to get "hello" in my browser but constantly getting "Cannot GET /api/posts/" in firefox and postman. What should I do now?
Correction :-
//Main app
app.use('/api/posts',posts);
I have a problem with my post data to the server. Not sure why i get an error for get when i changed my rout to post.
routes/feedback.js
const express = require("express");
const router = express.Router();
const { emailFeedback } = require("../controllers/feedback");
router.post("/feedback", emailFeedback);
module.exports = router;
server.js
const express = require("express");
const morgan = require("morgan");
const bodyParser = require("body-parser");
const cors = require("cors");
require("dotenv").config();
// import routes
const feedbackRoutes = require("./routes/feedback");
// app
const app = express();
// middlewares
app.use(morgan("dev"));
app.use(bodyParser.json());
app.use(cors());
// routes
app.use("/api", feedbackRoutes);
// port
const port = process.env.PORT || 8000;
app.listen(port, () => console.log(`Server is running on port ${port}`));
I believe the usual syntax for an express post route is as follows:
router.post("/feedback", function(req, res){
//grabbing the request body
console.log(req.body);
console.log(req.bodt);
//posting the request
res.json(req.body);
});
A callback function needs to be passed in and receive those request and response parameters (req, res).
In a nodejs project I'm getting this error : 'app.use() requires a middleware function error at the line 7 of this file :
const Router = require('./route');
const express = require('express');
const app = express();
const port = 3001;
app.use(express.json());
app.use(Router);
app.listen(port, () => {
console.log(`Example app listening at http://localhost:${port}`);
});
and I really don't get why I'm getting this error.
here are the routes files
const ProduitRouter = require('./produit');
const router = require("express").Router();
router.use("/produit", ProduitRouter);
module.exports = router;
const ProduitControleur = require("../controleur/produitDB");
const Router = require("express-promise-router");
const router = new Router;
//const router = require("express").Router();
router.get('/:id', ProduitControleur.getProduit);
router.post('/', ProduitControleur.postProduit);
router.patch('/', ProduitControleur.updateProduit);
router.delete('/', ProduitControleur.deleteProduit);
module.exports = router;
Try this.
In app.js
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const cors = require('cors');
const http = require('http');
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: true}));
app.use(cors());
require('./routes')(app); // path of file in which all your routes are defined.
module.exports = app;
in router file where all routes are define.
const express = require('express');
const router = express.Router();
const controller = require('path of controller');
router.post('/upload/file', verifyToken, controller .functionName);
module.exports = router;
As I can see, there is no imports for Router file
I'm trying to set the base URL for an Express app on startup.
I can hardcode the base URL and it works just fine:
app.use("/mybaseurl", routes);
However, if I try to use a variable instead which I can export on startup, it fails:
const baseUrl = "/mybaseurl";
app.use(baseUrl, routes);
The above doesn't work.
What am I missing?
test this code, work for me: http://localhost:3000/test
app.js:
const express = require('express');
const userRouter = require('./user');
const app = express();
app.use(express.json());
const baseUrl = '/test';
app.use(baseUrl, userRouter);
app.listen(3000, ()=> {
console.log('Server is up on port ', 3000)
});
user.js:
const express = require('express');
const router = new express.Router();
router.get('/', async (req, res) => {
res.status(200).send('hello');
});
module.exports = router;
how I can render my "firstsolution.ejs" page?
I have "server.js", "routes" folder which contain "firstsolution.ejs" and "views" folder which contain "solutions" folder and solutions folder contain "solution1.ejs"
enter image description here
server.js code is:
const fisrtsolution = require("./routes/firstsolution");
firstsolution.ejs code is:
const express = require("express")
const router = express.Router();
router.get("/", function(req, res) {
res.render("./solutions/solution1");
});
module.exports = router;
but when I try to enter "http://localhost:3000/firstsolution" I see "Cannot GET /firstsolution"
You forgot to include the route in the app :
const express = require("express");
const bodyParser = require("body-parser");
const mongoose = require("mongoose");
require('dotenv/config');
const app = express();
app.use(bodyParser.urlencoded({
extended: true
}));
app.use(express.static("public"));
app.set("view engine", "ejs"); // IMPORT ROUTES
const firstsolution = require("./routes/firstsolution");
app.use('/firstsolution', firstsolution); // <--------- here
mongoose.connect( process.env.DB_CONNECTION,{ useUnifiedTopology: true,useNewUrlParser: true }, () => console.log("connected to DB") );
const port = 3000;
app.listen(port, () => console.log(server ${port}))
Try this, I hope my code will help you.
server.js code is:
app.use(require('./routes/firstsolution'));
firstsolution.ejs code is:
const express = require("express")
const router = express.Router();
router.get("/", function(req, res) {
res.render("solutions/solution1");
});
module.exports = router;
