How to render multiple static files in express?

I am trying to use express to render a few different html files from my public folder. These are all static files. I also want to render a 404 page if a route is an invalid route is called. Here is my code.
const express = require("express")
const app = express()
app.use(express.static("public"))
app.get("/", (req, res) => {
res.render("index")
})
app.get("/about", (req, res) => {
res.render("about")
})
app.get("/contact-me", (req, res) => {
res.render("contact-me")
})
app.get("*", (req, res) => {
res.status(404).send("404 for all pages not defined in routes")
})
app.listen(8080)
The first route to render index.html works and the 404 status works, but all the other routes give me an error of "No default engine was specified and no extension provided." I tried added an ejs view engine, but the code still doesn't work. All html files are named properly and live in the "public" folder. Any help on this would be amazing! Thanks much!

You need to use handlebars for handling it. To see an example check this repo

Express in NodeJS: URL param breaks routing

I'm trying to use express to serve my index.html, its dependancies as well as handle url params. For some reason, adding a URL param seems to break the pathing.
My basic nodeJS webapp has the following folder structure:
|- server.js (nodeJS server code)
|- public (dir)
| - app.js (app logic dependancy)
| - index.html (base HTML file to be served from server.js)
index.html is importing app.js as follows:
<script type="text/javascript" src="app.js"></script>
My express routes are as follows:
app.use(express.static(__dirname + '/public'));
app.get('/', (req, res) => {
res.sendFile(__dirname + '/index.html');
});
app.get('/:country', (req, res) => {
res.sendFile(__dirname + '/index.html', {country:req.params.country});
}
I want the app to be served even when the country param is used.
However, when I add the URL param route, the above route stops working because express looks for index.html in the folder root, resulting in a 404.
Eg: http://localhost:3000/usa
Error: ENOENT: no such file or directory, stat '/Users/john/Projects/TestApp/index.html'

However, when I add the URL param route, the above route stops working because express looks for index.html in the folder root, resulting in a 404. Eg: http://localhost:3000/usa
Error: ENOENT: no such file or directory, stat '/Users/john/Projects/TestApp/index.html'
You should add public to the directory path, then.
app.get('/', (req, res) => {
res.sendFile(__dirname + '/public/index.html');
});
Or, to work cross-platform:
const path = require("path")
app.get("/", (req, res) => {
res.sendFile(path.join(__dirname, "public", "index.html"))
})

Different Path for Serving Static HTML files in Express

Just a quick question. Say I have 2 different static HTML files that I want to serve in Express, index.html and contact.html. I've been fiddling around and I currently use this barebone Express code to serve them:
const express = require('express');
const path = require('path');
const app = express();
app.use(express.static('public'))
app.get('/', function (req, res) {
res.sendFile('/index.html');
});
app.get('/contact', function (req, res) {
res.sendFile(__dirname + '/public/contact.html');
});
app.listen(3000, function () {
console.log('runnning on port 3000')
});
Question is, I tried to serve contact.html using
app.get('/contact', function (req, res) {
res.sendFile(__dirname + '/contact.html');
});
but it always resort to the root directory instead of the public directory. OTOH, I can server index.html just fine without having to explicitly adding /public in the response.
Can anybody point me what's the cause for that?
Thanks.

For the given file structure:
yourapp
|-- contact.html
|-- index.html
`-- server.js
The following code would work just fine:
app.get('/', function (req, res) {
res.sendFile(__dirname + '/index.html');
});
app.get('/contact', function (req, res) {
res.sendFile(__dirname + '/contact.html');
});
Assuming both index.html and contact.html have read access.
Remember, sendFile requires an absolute path and __dirname refers to your app directory. Make sure you give references according to your file location.

ExpressJS cannot get /route in Openshift, but locally it is working

My project have this following structure.
server.js
/node_modules
/build
vendor.js
main.js
index.html
I'm using express, and AngularJS's ui-router.
In server.js I have this code:
app.get('/*', function(req, res) {
res.sendFile(__dirname + '/build/index.html');
});
And locally it is working if I pass localhost:8080/hellothere, I get the correct page but when I've deployed, it doesn't.
Within the application if use the links to navigate the routes run, the URL is modified to /hellothere, but if I update the page or try to go straight to the absolute URL I get:
Cannot GET /hellothere
I'm already have tryied put:
app.get('/page1', function(req, res) {
res.sendFile(__dirname + '/build/index.html');
});
app.get('/page2', function(req, res) {
res.sendFile(__dirname + '/build/index.html');
});
...
And the behavior is the same of '/*'. Fine local, broke on cloud.
Any idea what's happening here?

And locally it is working if I pass localhost:8080/hellothere, I get
the correct page but when I've deployed, it doesn't.
The possible reason might be after deploying your base url might be domainname.com/appname and your local code is for localhost:portNumber not for localhost:portNumber/appname
So modify your path to
app.get('/appname/hellothere', function(req, res) {
res.send("hellothere is working");
});
instead of
app.get('/hellothere', function(req, res) {
res.send("hellothere is working");
});
To run it locally, now you will need localhost:portNumber/appname/hellothere

How come my views are not returned when exported from a file in my routes directory?

I'm just experimenting with basic routing in ExpressJS and so far I have two routes:
app.get('/', function(req,res) {
res.render('index');
});
app.get('/pics', function(req,res) {
res.render('pics');
});
When defined like this, in my app.js, everything works fine, but when exported as below, from individual files in my routes subdirectory, I get the error message that a callback function was expected, but an Object undefined was returned.
index.js:
exports.index = function(req,res) {
res.render('index');
});
pics.js
exports.pics = function(req, res) {
res.render('pics');
};
app.js
var routes = require('./routes');
app.get('/', routes.index);
app.get('/pics', routes.pics);
What am I doing wrong in the latter example to break everything?

The index route is working but your pics route isn't because you are trying to import it from index.js.
The route directory has index.js which means that if you do require('./route') you are actually doing require('./route/index'). This happens because index.js has a special meaning in Node.js.
So to get pics working you need to do:
app.get('/pics', require('./routes/pics').pics);
This can be really confusing and is a question that gets asked a lot on the IRC channel.

require('./routes') only loads ./routes/index.js, not ./routes/pics.js. So routes.pics will be undefined.

require() will try to load index.js.
Here is a small coffeescript snippet that you can paste (convert it to js) in index.js. It will autoload all your files(routes) in the current directory:
index.coffee
module.exports = (app) =>
require("fs").readdirSync(__dirname).forEach (file) ->
i = file.lastIndexOf('.')
ext = if (i < 0) then '' else file.substr(i)
if (ext == ".js" or ext == ".coffee") and file != "index"+ext
require("./" + file)(app)
app.js
require("./routes")(app)
someRoutes.js
app.get('/', function(req,res) {
res.render('index');
});
