I encountered a lot of instances of my problem, however none of them worked for me. Where is my server root, if both of these paths don't work? Static files aren't found neither under la-wars > public > css > file, nor under the more relative public > css > file.
This is how I use express for the purpose:
app.use(express.static(path.join(__dirname, 'public')));
And it results in the second 404 result below. With the first one, I had express.static() commented out and tried an absolute path in the markup.
EDIT: The entire entry point app:
var express = require('express'),
app = require('express')(),
ejs = require('ejs'),
path = require('path'),
cookieParser = require('cookie-parser'),
util = require('util'),
port = process.env.PORT || 3000,
user = require('./models/user.js'),
formidable = require('formidable'),
router = express.Router();
app.use(express.static(path.join(__dirname, 'public')));
app.set('views', __dirname + '/views');
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
//app.use(require('.middleware/auth.js'));
app.use(require('./routes')(express));
app.listen(port);
It depends what the url is you put on your html pages, but from the console's error window, I'm going to guess this (notice extra first argument) solves your problem:
app.use("/public", express.static(__dirname + '/public'));
It seems you use both "/public" (for the js) and "public" (for the css) in your html file. The code above should at least fix one of the two errors.
The call:
app.use(express.static(path.join(__dirname, 'public')));
is saying that it could serve your files in the 'public' folder directly, so you can keep this but in the html files remove the "public/" from the urls and begin them with "/" directly.
You will find slider.jsat the url of http://localhost:3000/js/slider.js - that's how it works.

Is there any way to exclude sub directory from express static middleware in express 4.8.5.
For example if I have :
app.use(express.static(__dirname + 'public'));
And my public directory is like this :
- public
- css
- images
- scripts
- index.html
- exclude_me
- scripts
- views
- index.html
So I need to exclude last sub directory and when user does :
GET /exclude_me
It should call my route rather than returning directory automatically.
I can't just remove it from public dir because it depends on stuff inside it because public directory is angular application and exclude_me is another angular application that fetches scripts from /exclude_me/scripts AND from /public/scripts.
I know it is little confusing but it is how it is and I cannot just remove it from public dir because it won't see public/scripts any more which are needed and I cannot leave it because I cannot authorize it then (all authorization is in public/scripts)
If there is some smarter way to do this, feel free to let me know :)
You can add your own middleware. Here's what I did to exclude some folders:
app.use('/public', (req, res, next) => {
if (env !== 'development') {
var result = req.url.match(/^\/js\/(maps|src)\/.+\.js$/)
if (result) {
return res.status(403).end('403 Forbidden')
}
}
next()
})
app.use('/public', express.static(path.join(__dirname, '/public')))
It's possible by adding regular expressions to the first optional param of use method.
According with Express 4.x API path documentation.
Example, I don't want to give access to my secure folder inside public folder:
var express = require('express');
var app = express();
app.use([/^\/public\/secure($|\/)/, '/public'], express.static(__dirname + '/public'));
This will allow you to access all files but not the ones in the secure folder.
You can use it also to restrict a file extension, example files that ends with .js.map:
app.use([/(.*)\.js\.map$/, '/public'], express.static(__dirname + '/public'));
And you also can add multiple rules, like this example where secure folder and files that end with .js.map are ignored from the static folder:
app.use([/^\/public\/secure($|\/)/, /(.*)\.js\.map$/, '/public'], express.static(__dirname + '/public'));
I had a similar problem, which may be the answer you were seeking. Given the following directory:
public
css/
images/
secure/
index.html
The Express Middleware stack I wanted was this:
1. Static files (except the `secure/` directory)
2. Logging
3. Authentication
4. `secure/` static files
Here's how I solved it:
var express = require('express');
var path = require('path');
var app = express();
// path.join here makes it work cross platform with Windows / Linux / etc
var statics = express.static(path.join(__dirname, 'public'));
function secureStatic(secure) {
return function (req, res, next) {
if (/^\/secure/.test(req.path) === !!secure) return statics(req, res, next);
return next();
};
}
// add public files
app.use(secureStatic());
app.use(logging());
app.use(authentication());
// add secured files
app.use(secureStatic(true));
This will only serve public files when unauthenticated, and only serve secure files after authentication.
Most solutions above are to use a middleware.
However, there is a just easier way to solve this.
Don't serve static assests directly with the dir public rather than serve dir just what you want to serve with a virtual path prefix .
You can serve like below
var express = require('express');
var app = express();
app.use('/public', __dirname + 'css');
app.use('/public', __dirname + 'images');

Is it possible in any way to use hogan.js as template engine with layouts something like
"Razor or master pages in .NET"?
I would get a result like this:
layout.hjs:
contains "header" & "footer"
and
index.hjs:
will include layout.hjs and contain only page content.
sure:
layout.hjs:
{{> header}}
{{$content}}
default content
{{/content}}
{{> footer}}
index.hjs:
{{<layout}}
{{$content}}
your content goes here
{{/content}}
{{/layout}}
see the hogan test file for all it can do:
https://github.com/twitter/hogan.js/blob/master/test/index.js
btw. this is Hogan#3.0.0, get it with a git url with mpn
I'm not sure what you mean, "Razor or master pages in .NET"? What are you looking to do, use view partials?
But the basic way of setting up Hogan.js for Express is as follows:
var express = require('express');
var app = express();
app.set('views', __dirname + '/views');
app.set('view engine', 'hjs');
app.use(app.router);
app.use(express.static( __dirname + '/public' ));
app.get('/', function( req, res, next ) {
res.render('index');
});
app.listen(3000);
You will have to npm install express [--save], npm install hjs [--save], depending if it's inside your package.json already or not.
Then you just make a views directory and throw an index.hjs file and you're set.
Let me know what you want to do with your templates and we can work from there.
I'm trying to run my first express app, but can't seem to get my webpage to show. I have the following code:
var fs = require("fs");
var config = JSON.parse(fs.readFileSync("files/config.json"));
var host = config.host;
var port = config.port;
var express = require("express");
var app = express();
app.use(app.router);
app.use(express.static(__dirname + "/public"));
app.get("/", function(request, response){
response.send("hello!");
});
app.listen(port, host);
console.log("Listening on port" + port);
Here is my directory tree
nodejs/
js/
javascript.js
public/
index.html
I know the server is running because I get my "Hello!" response in the browser when I run 127.0.0.01:1337
But when I try and type the webpage 1227.0.0.1:1337/index.html, I get Cannot GET /index.html displayed in the browser
So I'm guessing it's something wrong with the name value in my get method, but can't figure out what it is and how to fix it.
Your app will only route page requests that are set up at the time of your app.use(app.router) call. So reorder your app.use calls to be one of the following:
Express 3
app.use(express.static(__dirname + "/public"));
app.use(app.router);
__dirname is the directory that the executing script resides in, so because that lives in the js directory that's a peer to public your code would need to be:
app.use(express.static(__dirname + "/../public"));
app.use(app.router);
Express 4
Express 4 removes the need to manually do app.use(app.router). With Express 4 you just need:
app.use(express.static(__dirname + "/../public"));
I had this issue .... after a lot of trouble I find that if you run two workspaces or project at t time then it will create this scenario. so you might open only a workspace at a time and not just file ... open the hole folder then run the specific file.make the following change in your VS code setting.
setup the settings
For 64bit system.
{
"liveServer.settings.AdvanceCustomBrowserCmdLine: ": "C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe",
"liveServer.settings.NoBrowser": false
}
For 32bit system.
{
"liveServer.settings.AdvanceCustomBrowserCmdLine: ": "C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe",
"liveServer.settings.NoBrowser": false
}
I cannot get this simple app.js to work: static files are served but jade and styl files are not compiled.
Here the __dirname ls:
damianomacbook:www damiano$ ls
app.jade app.js app.styl config.xml johnd.jpg
.jade and .styl files are served normally and plain.
Here what happens when curling css and html files (which the middlewares functions are supposed to generate on the fly):
damianomacbook:www damiano$ curl localhost:8080/app.css
curl: (52) Empty reply from server
damianomacbook:www damiano$ curl localhost:8080/app.html
Cannot GET /app.html
What's missing?
Guilty code:
var express = require('express');
var stylus = require('stylus');
var nib = require('nib');
var app = express();
function compile(str, path) {
return
stylus(str)
.set('filename', path)
.use(nib());
}
app.use(express.logger('dev'));
app.set('views', __dirname);
app.set('view engine', 'jade');
app.use(stylus.middleware({
src: __dirname,
compile: compile
}));
app.use(express.static(__dirname));
app.listen(8080);
Your GET /app.html is failing because serving HTML pages is done with the express router, not middleware, and you don't have any routes defined. The static middleware doesn't convert anything (thus the name), so it's not going to serve /app.html unless there's an actual app.html file on disk. To get /app.html working, add:
app.get('/app.html', function (req, res) { res.render('app');});
//or you probably want app.get('/', ...if you want this to be your home page
//you probably also don't want/need ".html" in your URLs as this has fallen out of style
Your stylus problem is the automatic semicolon insertion monster. You must not put the "return" keyword on a line by itself. Your compile function is returning undefined instead of a stylus instance. Keep the compile formatted as it is on the nib documentation and all is well.
I'm serving static video files (.ogv and .mov) with node.js and video.js plugin. However, node.js keeps crashing with below error message:
node: ../deps/uv/src/unix/stream.c:1319: uv_read_stop: Assertion `!uv__io_active(&stream->io_watcher, 4) || !(&stream->write_completed_queue == (&stream->write_completed_queue)->prev) || !(&stream->write_queue == (&stream->write_queue)->prev) || stream->shutdown_req != ((void *)0) || stream->connect_req != ((void *)0)' failed.
This is node.js code:
app.configure (function () {
app.set ('views', path.join (__dirname, 'templates'));
app.set ('view engine', 'jade');
app.use (express.favicon (path.join (__dirname, '/img/favicon.ico')));
app.use ('/video', express.static (path.join (__dirname, 'public')));
app.use (express.static (path.join (__dirname, 'public')));
//bodyParser, methodOverride, cookieParser and session calls here
app.use (app.router);
});
my node.js version is "v0.10.4"
Directory structure:
/myApp
/myApp/public
/myApp/public/video
A pretty straight forward static file serving. Tried placing express.static after app.router, and above favicon, no such luck.
Appreciate any advice render.
So, for the sake of completeness: This is a known bug in libuv which has been solved since 0.10.9. There has been a similar issue which is resolved since 0.10.11.
