var express = require('express');
var app = express();
app.get('/', function(req, res){
app.use(express.static('../../www'))
})
app.listen(8080)
according to docs this should work but it just returns a page of garbled text
It's better to use path module to join the current folder and relative path to an absolute path.
var express = require('express');
var app = express();
app.use(express.static(path.join(__dirname, '../../www')));
app.get('/', function(req, res){
res.send('done');
});
app.listen(8080);
As #bulkan comments, you use /style.css to access www/style.css.
Move the app.use(express.static('../../www')); outside of the app.get like so;
var express = require('express');
var app = express();
app.use(express.static('../../www'));
app.get('/', function(req, res){
res.send('done');
});
app.listen(8080);

This is my home.js code
// import modules
var express = require('express');
var mongoose = require('mongoose');
var bodyparser = require('body-parser');
var cors = require ('cors');
var path = require ('path');
var app = express();
const route= require('./routes/route');
//port no
const port =3000
app.use(cors());
app.use(bodyparser.json());
//static files
app.use(express.static(path.join(__dirname,'public')));
app.use('./api', route);
//testing server
app.get('/', (req,res)=>{
res.send('foober');
})
app.listen(port,()=>{
console.log('server started at port:' + port);
});
And this the route.js code
const express = require('express');
const router = express.Router();
router.get('/contacts', (req, res, next )=>{
res.send('retrieve contact');
});
module.exports =router;
But whenever I run 'localhost:3000/api/contacts' i get 'Cannot GET /api/contacts' error. I am very new at this, what am I doing wrong?
A dot in an url is there to seperate domains, if your route is mounted at ./api you would have to visit yourserver.com./api which won't work as the url is invalid.
I'm building my first Node application and having some trouble displaying the page that I want with a GET request. I have installed ejs (opinions welcome on that!) so my understanding is that I do not need to define the 'views' folder. Here is my routes file so far:
const express = require('express');
const router = express.Router();
const Event = require('../models/event')
router.get('/'), function(req, res, next){
/* Event.find({}).then(function(events){
res.send(events);
});
});*/
res.render('../../index');
};
router.post('/events', (req, res) => {
Event.create(req.body);
res.send({type: POST})
});
module.exports = router;
The database is connecting just fine, which I can see with the code that I have commented out in the get request. But for some reason I can't render my index file. My file structure is as follows:
File tree:
So I need to go up two levels, correct? I tried index, index.ejs, ../index, views/index, nothing has worked. What am I doing wrong?
EDIT: this is my server.js:
const express = require('express');
const app = express();
const bodyParser = require('body-parser');
const mongoose = require('mongoose');
const routes = require('./routes/index');
var path = require("path");
app.set('view engine', 'ejs');
app.set('views', path.join(__dirname, 'views'));
app.use(bodyParser.json());
app.use(express.static('public'));
app.use(routes);
app.use(bodyParser.urlencoded({extended: true}))
mongoose.connect('mongodb://junk:junk#ds141242.mlab.com:41242/alaska-events');
app.listen(3000, () => {
console.log('listening on 3000')
});
views folder is placed directly in root folder, and using we app.set('views', path.join(__dirname, 'views')); point it to views folder. So in render directly mention the view name.
router.get('/', function(req, res, next){
res.render('index');
});
Thanks for your help everyone, turned out to be just a typo. router.get('/'), function(req, res, next) should have been router.get('/', function(req, res, next).
I'm creating a MEAN Stack application where angular has setup in /client folder. I want that when I run npm start command in /client folder it should render index.html file from /views folder, what I'm doing wrong getting this error
Cannot GET /
Folder structure is as follows.
meanApp
----- client (angluar2 setup here but doesn't have an index.html file)
---------- app
----- views
----------index.html
----- routes
----- server.js
Codes in server.js
var express = require("express");
var path = require("path");
var bodyParser = require("body-parser");
var index = require('./routes/index');
var tasks = require("./routes/tasks");
var app = express();
//View engines
app.set("views", path.join(__dirname,'views'));
app.set("view engine", 'ejs');
app.engine("html", require("ejs").renderFile);
//Set static folder
app.use(express.static(path.join(__dirname,'client')));
// Body parser
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended:false}));
app.use('/', index);
app.use('/index', index);
app.use('/api', tasks);
//listen
app.listen(3000, function(){
console.log("Server listing # 3000");
});
Here you need to define route for express server like :
app.set('appPath', 'client'); //this is a folder where your index.html is
app.route('/*')
.get(function(req, res) {
res.sendfile(app.get('appPath') + '/index.html');
});
This will cause every call in broweser to render index file.
const http = require('http');
fs = require('fs');
var express = require('express');
var bodyParser = require('body-parser');
var expressValidator = require('express-validator');
var app = express();
app.set('appPath', 'views');
app.use(express.static(__dirname + '/views'));
app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());
app.use(expressValidator());
app.use('/*', function(req, res, next) {
res.sendfile(app.get('appPath') + '/index.html');
});
http.createServer(app).listen(3001, function() {
console.log(`Express server listening on port 3001`);
});
exports = module.exports = app;
I have issue setting up routes for user in below code, I want to use express middleware and trying routes using app.use.
index.js is invoking user controller method once api's is being called So in below code i am trying to post data api/users from client but it returns 404.
How can i fix this issue using below routes setup ?
server.js
var express = require('express');
var app = express();
var bodyParser = require('body-parser');
var methodOverride = require('method-override');
var mongoose = require('mongoose');
console.log(mongoose.connection.readyState);
var db = require('./config/db');
var port = process.env.PORT || 8080;
mongoose.connect(db.url);
app.use(methodOverride('X-HTTP-Method-Override'));
app.use(express.static(__dirname + '/public'));
require('./app/routes')(app); // configure our routes
require('./config/express')(app);
app.listen(port);
console.log('listening on port ' + port);
exports = module.exports = app;
app > routes.js
module.exports = function(app) {
app.use('api/users', require('./api/user'));
app.get('*', function(req, res) {
res.sendfile('./public/views/index.html'); // load our public/index.html file
// res.sendFile(path.join(__dirname, ''../public/views/index.html''));
});
};
config > express.js
var express = require('express');
var morgan = require('morgan');
var bodyParser = require('body-parser');
// import cookieParser from 'cookie-parser';
// import errorHandler from 'errorhandler';
var path = require('path');
// import lusca from 'lusca';
var config = require('./db');
var mongoose = require('mongoose');
//var mongoStore = connectMongo(session);
module.exports = function(app) {
// app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
app.use(methodOverride());
}
User index where i will handle all crud operation for user
app > api > user > index.js
var express = require('express');
var controller = require('./user.controller');
var router = express.Router();
router.get('/', controller.index);
router.post('/',controller.create);
module.exports = router;
1st:
To handle all request
Bind application-level middleware to an instance of the app object by using the app.use() and app.METHOD() functions, where METHOD is the HTTP method of the request that the middleware function handles (such as GET, PUT, or POST) in lowercase.
This example shows a middleware function with no mount path. The function is executed every time the app receives a request.
app.use(function(req,res)
{
res.sendfile('./public/views/index.html');
console.log("Not found....I will handle *unhandle* rout here for you");
})
// app.get('*', function(req, res) use the above function instead of this
But this function at the end so it will only excute when no route path found to the app object.
Express documentation
2nd:
To handle createuser
var express = require('express');
var controller = require('./user.controller');
var router = express.Router();
// you must define route which you want to handle in user file
router.get('/api/user', controller.index);
router.post('/',controller.create);
module.exports = router;
Update working example with some explanation
Your app.js file
var express=require('express')
var app=express()
app.use('api/user',require('./user'))
app.use('/',require('./user'))
app.use(function(req,res)
{
res.sendfile('stack10.html')
console.log("Not found....I will handle *unhandle* rout here for you");
})
app.listen(8080,function()
{
console.log("server listening on port 8080")
})
user.js
var express = require('express')
var router = express.Router()
var app=express()
router.get('/api/user', function(req, res) {
res.send('respond for ..../api/user')
});
router.get('/',function (req,res) {
res.send('respose for ..../')
})
module.exports = router;
Your app.use will be app.use(api/user) while in user will be router.get(/api/user) so when u try http://127.0.0.1:8080/api/user
your response will be respond for ..../api/user
var express = require('express'),
app = express(),
db = require('./db'),
bodyParser = require('body-parser'),
controller = require('./controller');
app.use(express.static('../public'));
app.get('/server', function (req, res) {
console.log(__dirname);
res.sendFile('/../client/index.html');
});
I have this express server set up but using the code above I get "Cannot GET /" when I view localhost:portnumber. If I change the GET method to:
app.get('/', function(req, res) {
res.sendFile(__dirname + '../client/index.html');
});
I get "'C:\Users\TC\Documents\Desktop\myapp\multiplayerWebSite\server..\client\index.html' at Error (native)" and if I change it to:
app.get('/', function(req, res) {
res.sendFile('../client/index.html');
});
I get "TypeError: path must be absolute or specify root to res.sendFile"
Error: ENOENT: no such file or directory
The server was working perfectly when I had everything in the root directory, but I wanted to change the folder structure to make it more neat/professional. If anyone could tell me what I'm doing wrong I'd appreciate it greatly. Thank you in advance!
You can use path module, there is a join method that take multiple paths to make one.
Exemple if you do:
path.join('test/musicfolder', '../videofolder/allreadyseen')
you will get 'test/videofolder/allreadyseen' .
you can see all the doc here : https://nodejs.org/api/path.html
var express = require('express'),
path = require('path'),
app = express(),
db = require('./db'),
bodyParser = require('body-parser'),
controller = require('./controller');
app.use(express.static(path.join(__dirname, '../public')));
app.get('/server', function (req, res) {
console.log(__dirname);
res.sendFile(path.join(__dirname, '../client/index.html'));
});
