I'm using Vue.js and the vue-router and would like to server the static files via Node.JS.
So I've create server.js with the following code:
// server.js
var express = require('express');
var path = require('path');
var serveStatic = require('serve-static');
app = express();
app.use(serveStatic(__dirname + "/dist"));
var port = process.env.PORT || 5000;
app.listen(port);
console.log('server started '+ port);
It seems to work, but only when I click around.
If I visit ex. my-url.com/some-path/another-path it fails.
Am I missing something?
Ex. I'm getting:
Cannot GET /cars with I type www.my-domain.com/cars into the address bar in the browser, but visiting www.my-domain.com and clicking on cars does work.
You need to setup your server to redirect users to the appropriate server location. Please read the Vue Router - HTML5 History Mode docs.
When using history mode, the URL will look "normal," e.g.
http://oursite.com/user/id. Beautiful!
Here comes a problem, though: Since our app is a single page client
side app, without a proper server configuration, the users will get a
404 error if they access http://oursite.com/user/id directly in
their browser. Now that's ugly.
Not to worry: To fix the issue, all you need to do is add a simple
catch-all fallback route to your server. If the URL doesn't match any
static assets, it should serve the same index.html page that your
app lives in. Beautiful, again!
The main thing that you need to do is have all routes lead to the root route. Alternatively, since you are using Express, you can leverage the connect-history-api-fallback which the Vue Router docs recommend.

I am making an application with node.js and I basically want render a canvas with node.js so I can access a json file on the server since you can't change client storage on browsers. To add on when running my files I get this weird syntax error.
Uncaught SyntaxError: Unexpected token '<'
Further examination shows that my javascript files that I am requiring (see internals folder) are being overwritten with html, thus causing the error. My question is why is it overwritting only the files I am requiring from the html I am rendering? To add on I am running on a dynamic port (65535) and on a localhost (client). My code is here
Your node server is not serving your static files, it only serves one html.
You might need to set up a static file server like or programm you server to lookup GET /internals/render.js and scaleCanvas.js
You can use express for that, it has all this out of the box.
https://expressjs.com/en/starter/static-files.html
var app, server,
express = require('express'),
path = require('path'),
host = process.env.HOST || '127.0.0.1',
port = process.env.PORT || 3000,
root = path.resolve(__dirname, '..');
app = express()
app.use(express.static(root + '/public'));
server = app.listen(port, host, serverStarted);
function serverStarted () {
console.log('Server started', host, port);
console.log('Root directory', root);
console.log('Press Ctrl+C to exit...\n');
}
This is because you are sending the index.html file for all requests in your app.js file, ignoring the request URL.
You need to properly serve the JS files. You can take a look here for more details: https://nodejs.org/en/knowledge/HTTP/servers/how-to-serve-static-files/
I have a simple webpack template vue app, and let's say I have a page with
http://localhost:8080/profile
On my local page, I can go from any page to /profile and even once on /profile I can refresh/reload the page and I get no error.
But I deployed my app on heroku and even though I can navigate from any page to any other, but if I am for example on /profile page and I hit refresh i get
Cannot GET /statement
what could be the problem?
You trying to use history mode of router without backend.
For getting things working, you may use Express JS. Previous answer is not working for me and i write my own server script.
Here is the my server.js for running Vue app with history mode.
server.js (with Express):
const express = require('express');
const path = require('path');
const history = require('connect-history-api-fallback');
const app = express();
const staticFileMiddleware = express.static(path.join(__dirname + '/dist'));
app.use(staticFileMiddleware);
app.use(history({
disableDotRule: true,
verbose: true
}));
app.use(staticFileMiddleware);
app.get('/', function (req, res) {
res.render(path.join(__dirname + '/dist/index.html'));
});
var server = app.listen(process.env.PORT || 8080, function () {
var port = server.address().port;
console.log("App now running on port", port);
});
Place this file in the root directory of your project (not src).
Run this script with Node: node server.js
Don't forget build your app for production ;)!
I think your vue-router is in HTML5 History Mode. https://router.vuejs.org/en/essentials/history-mode.html
In development mode, the webpack-dev-server handles the redirect for your but your need to configure your server used in production to redirect your routes.
I have installed node inside a folder and am forwarding it through apache. I am doing this because I have several virtualhosts run through apache, and I do not want to take the time to set up everything through node.
Apache and Node.js on the Same Server
However, I am trying to create a chat engine. I try to include some js files, but they search for http://example.org/myscript.js instead of http://example.org/chat/myscript.js
I got around this by using
<base href="/chat/">
However, now I am trying to integrate socket.io. I included socket.io from https://cdn.socket.io/socket.io-1.3.5.js because I could not get the locally serverd /socket.io/socket.io.js to properly be located.
Now socket.io is trying to connect to http://example.org/socket.io
That dierectory does not exist. If anything, the proper path should be http://example.org/chat/socket.io
I have been looking all over the internet for a solution. There must be something fundamental or obvious about how nodejs/express operates that I am missing. Thanks a million!
Server.js - This is the file I start with node.
var express = require('express');
var path = require('path');
var app = express();
var http = require('http').createServer(app);
var io = require('socket.io').listen(http, { log: true, resource:'/socket.io/'});
app.use('/socket.io', express.static(path.join(__dirname,'/node_modules/socket.io/lib/')));
app.use('/bootstrap', express.static(path.join(__dirname,'/node_modules/bootstrap/dist/')));
app.use('/', express.static(__dirname));
var server = app.listen(8000);
io.sockets.on('connection', function(socket) {
console.log('A user connected!');
})
I am new to expressjs and am trying to get my express application (done with the express generator) working on my website, I currently uploaded the directory which is is contained in like so..
http://www.example.com/express-app-here
so I could see it working online. However, when I navigate to where the App is, I seem to only get the directory structure, and express isn't routing me to the appropriate place like it is when I go to localhost:3000.
I take it this has something to do with the fact that express isn't executing my application? Locally,
npm start
needs to be run on the console in order to get it to run, is there some kind of log I need to execute this command in? Or something I need to change in the app.js or /bin directory?
As it was said in the comments, you need to have nodejs installed on your server. It's not as simple as just copying the node app directory over to the server.
You will have to install node and npm on the server, and then run your app from the server, probably using npm start like you were doing on your local machine.
From there, you will want to go into your app code and make sure a route exists for /express-app-here unless you want www.example.com:3000 to take you directly to the express app.
Basically do it like this:`
var express = require('express');
var http = require('http');
var app = express();
var server = http.createServer(app);
var port = process.env.PORT || config.webServer.port || 3000;
server.listen(port, function () {
console.log('server running');
console.log(port);
console.log(server);
});
exports.module = exports = app;
save it app.js
Go to path via cmd. Now run:-
1)npm install express
2)npm install http
3)node app.js
Will be enough to run express server
I'm trying to run a node.js application on my freebsd server, but I can't get the socket.io library to work with it. I've tried including:
<script src="/socket.io/socket.io.js"></script>
Which gives a 404 error, and if i link directly to the file (i.e. where it is in my public_html folder) I get the io not defined error.
Thanks in advance
Try creating another node.js application that has this single line in it and then run it with node.js
var io = require('socket.io').listen(8000);
Then in your browser visit http://127.0.0.1:8000 and you should get the friendly "Welcome to socket.io." greeting. If you are getting this then socket.io is running and will serve the socket.io.js file.
The only other thing that I can think of that might be happening is that you might not be linking to the alternate port in your client file. Unless you're running the socket.io server on express which is running on port 80. For now create a client file that has the script source for socket.io set to
<script src="http://127.0.0.1:8000/socket.io/socket.io.js"> </script>
This should connect to the socket.io server running on port 8000 and get the socket.io.js file.
Your node.js application still has to serve it - it does not get served automagically. What do you have in your server? It should be something like
var app = require('express').createServer();
var io = require('socket.io').listen(app);
or similar (the listen is important). The location is not a real location on the disk - socket.io library should intercept the URL and serve its clientside library, as far as I understand.
Add the following after body parser:
, express.static(__dirname + "/public")
So something like:
var app = module.exports = express.createServer(
express.bodyParser()
, express.static(__dirname + "/public")
);
For those who got the same kind of issue if they run (open) your html file directly from your local file directory(ex: file:///C:/Users/index.html).
Solution: You have to run(open) the file through localhost (ex: http://localhost:3000/index.html) where the server is listening to.
Below code snippet shows how to create a server and how to wire together with the express and socket.io
const express = require("express");
const app = express();
const httpServer = require("http").createServer(app);
const io = require("socket.io")(httpServer);
///////////////////////////////////////////////////////////////
// Any other server-side code goes here //
//////////////////////////////////////////////////////////////
httpServer.listen(3000, () => {
console.log(`Server listening to port 3000`);
});
