I have a node.js app with express and jade templates.
Just now I've running like any-host:8000 but I need to change to any-host:8000/web/
but this causes change all href and location css,img,js...
Any idea to do something to achieve transparently
I've tried with:
app.namespace('/admin', function(){...}
but then I need change the href of all the html links in the app.
Any suggestions?
app.use('/urlbase', express.static(__dirname + '/public'));
(assuming your app is located in myapp/).

I've a node, express system installed working on a host.
All requests are going through in the app.get('/path'... format
however in the domain I've html folder with static content that I want to serve
http://domain.com/html/attendee
http://domain.com/html/sponsors
and don't want node/express to intercept these requests and let them go through directly, not even serve through nodejs, otherwise relative linking problem.
Please suggest a solution.
You can't do it that way. node doesn't serve ANY content by default - it is not like some other web servers in that regard.
Instead, you specifically configure express to serve content from certain paths directly from the file system by inserting the right middleware commands early in the middleware stack.
For example, in one of my node apps, I use this middleware:
// static routes that get no further processing
app.use('/img', express.static(__dirname + '/img'));
app.use('/lib', express.static(__dirname + '/lib'));
This tells express that any content that starts with "/img" should be served directly from the appDirectory + "/img" directory. Same for elements in "/lib". One nice thing about this is that the paths you expose to the outside world do not have to be the same as the paths you use on your server and, in fact, by changing a few characters in your code, you can easily map to different directory.
I would like to pre-render my Jade files with a Gulp task, so that my views are not rendered on-the-fly. From my understanding, if one is using the Jade view engine with Express 4, this is how the Jade templates become their HTML equivalents (please correct me if I am wrong).
I realize that the views directory is typically pointed to using the statement app.set('views', __dirname + '/views/directory');, where app is an Express app. However, I am not sure how to force Express to serve the pre-rendered HTML files instead.
Any suggestions are appreciated.
I'm writing a single page web application using node.js and express. After going through some online tutorials, I found out this is how express.js serves a client directory with HTML, javascript and css
app.use(express.static(__dirname + '/public'));
This works great except the fact that public directory has to have .html root file which is static. I'd like to know how can I serve a dynamic HTML file with this same approach.
I want to insert some data into the page for example "Hello user_name" at the top. How do I do that for this single file.
I want to only do it once, at the startup, after that my application will make rest API calls and get plain JSON responses which it will then put it in the page.
You cannot use the express static server to serve dynamic files as far as I'm aware. In order to serve a dynamic HTML you need to use a templating engine, such as jade or any of these templating engines.
Jade is pretty straightforward to use and is supported by express by default. To set up jade, include the following lines in your app configuration block:
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
The first line sets your views directory - from which the template files would be served. Since you want to serve only an index file, this directory would contain your index.jade template. The second line sets jade as the templating engine.
Now, instead of using the static server to serve the index.html, you need to create a get route '/' to serve the index file, like so:
app.get('/', function(req, res) {
res.render('index', {user_name: username});
});
I can't find an answer to this, despite it seeming rather useful.
I would like to host a site using node.js to serve compiled jade files instead of html files. Currently, I'm using:
app.get('/', function(req, res) {
app.use(express.static(__dirname));
});
How can I get it to find page.jade when someone types in domain.com/page? And furthermore, could I write links that way in the jade file (so a(href='page') link would link to the aforementioned page)?
Set your path as
app.get('/:pageName')
// more code
// then
res.render(req.params.pageName+'.jade')
req.params will contain the last part in property name pageName
Express has a number of possible options for what it calls a "view engine". In order to have it process jade files and serve them as html you must configure it to do so.
One of the easiest ways to do this, if you are starting fresh, is to simply create your project using the express command as mentioned in their guide. The default views engine is jade and the following command sets stylus as the css processor:
express --css stylus myapp
If, instead, you are configuring your own server you need to configure the views engine:
app.configure(function(){
app.set('views', path.join(staticDir,'views'));
app.set('view engine', 'jade');
... the rest of your setup ...
}
I need to parse parameters in the URL that come in this form:
localhost:8080/p/a=12345&b=acbd
After the variables are read, I load a HTML file that is in the public folder of my express server. That works ok. The problem is that my HTML file load several JS and CSS files and since the path is localhost:8080/p/ the files with relative paths can't be found.
What I need is something similar to the apache URL rewrite, where I can send the traffic to a specific file and change the URL to look in the way I want. I haven't found a node module that does that, any suggestions?
If you are using the static middleware to serve your static files, you can use
app.use('/p', express.static(__dirname + '/public'));
instead of
app.use(express.static(__dirname + '/public'));
You can see more details in the document of the Express
