react app with express.js route setup - javascript

I was using angular.js and I do this in express.js
app.get("*", function (req, res) {
res.redirect('/#' + req.originalUrl)
})
so that the browser will use the route of angular instead of express. But how to do that with react router? I have 2 folder, named server and client, server folder has express and api logic while client folder simply a react app.

You need to put the path in of the HTML file you are rendering your app to
app.get("/",(res,res) => {
res.sendFile('put the path of the html file you are rendering your app into here');
}
here is an example of a express server.js that works with react
var express = require('express');
var bodyParser = require('body-parser');
var logger = require('morgan');
var app = express();
var PORT = process.env.PORT || 3000;
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended:true}));
app.use(bodyParser.text());
app.use(bodyParser.json({type: 'application/vnd.api+json'}));
app.use(express.static('./public'));
app.get('/', function(req,res){
res.sendFile('./public/index.html');
});
app.listen(PORT, function(){
console.log("Listening on port: " + PORT);
});

Express js router not working

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.

Unable to render index.html file from my view folder in angular2

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;

How to use express middleware to handle all routes?

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

Node + Express JS API is not working

I'm a beginner in node.js but I try a little harder to setup a structure in node + express js.I start doing with the front-end and separate API structure.I put a single app.js for both API and front-end.But my API is not working. it gives error Cannot GET /api/users when i call http://localhost:3000/api/users. please help
api
-controllers
-helpers
-middlewares
-models
-routes.js
app.js
controllers
helpers
middlewares
models
node_modules
package.json
public
views
app.js
var express = require('express')
, app = express()
, bodyParser = require('body-parser')
, port = process.env.PORT || 3000
var path = require('path');
app.set('views', path.join(__dirname, 'views/'));
app.set('view engine', 'ejs')
app.use(express.static(__dirname + '/public'))
app.use(bodyParser.json())
app.use(bodyParser.urlencoded({extended: true}))
app.use(require('./controllers'))
var routes = require('./api/routes');
app.use('/api', routes);
app.listen(port, function() {
console.log('Listening on port ' + port)
})
routes.js
var express = require('express')
, router = express.Router()
var usersController = require('./controllers/users');
module.exports = function (app) {
app.get('/users', usersController.getUser);
};
module.exports = router;
users.js(controller)
module.exports = {
getUser: function (req, res) {
console.log("sdfdsfdsfsd");
res.setHeader('Content-Type', 'application/json');
res.send(JSON.stringify({"msg": "welcome user"}));
}
}
In your routes.js file you are exporting two things. Try to only export the router
var express = require('express')
, router = express.Router()
var usersController = require('./controllers/users');
router.get('/users', usersController.getUser);
module.exports = router;

Express routing error Cannot Get /api/name

Having some trouble setting up the restful API for my express app.
Here is my app.js:
var express = require('express'),
app = express(),
bodyParser = require('body-parser'),
methodOverride = require('method-override');
routes = require('./routes'),
api = require('./routes/api'),
port = process.env.PORT || 3000;
app.use(express.static(__dirname + '/public'));
app.use(bodyParser.json());
app.use(methodOverride());
app.use(bodyParser.urlencoded({extended: true}));
// Page Routes
app.get('/', routes.index);
app.get('/partials/:filename', routes.partials);
// // API Routes
app.get('/api/name', api.name);
app.listen(port, function() {
console.log('Listening on port ' + port);
});
In /routes/api.js I have the following test function:
exports.name = function (req, res) {
res.json({
name: 'Test'
});
};
Currently I get the following error when i go to http://my_ip/api/name
Cannot GET /api/name
Any ideas?
Thanks
The following code is working for me. I think there is some issue with your routes package. Can you share the code of 'routes' package and file structure ?
app.js
var express = require('express'),
app = express(),
routes = require('./routes');
api = require('./routes/api'),
port = process.env.PORT || 3000;
// Page Routes
app.get('/', routes.index);
// API Routes
app.get('/api/name', api.name);
app.listen(port, function() {
console.log('Listening on port ' + port);
});
/routes/api.js
exports.name = function (req, res) {
res.json({
name: 'Test'
});
};
/routes.js
exports.index = function (req, res) {
res.json({
name: 'Index'
});
};
