&gt; Code buffered by = is escaped by
&gt; default for security, however to output unescaped return values you
&gt; may use !=

    p!= aVarContainingHTML

The syntax you need is :

    !{yourJsVariable}

if you use `#{yourJsVariable}` it shows &amp;lt; &amp;gt;, but with `!{}` it doesn&#39;t.



I am developing a website in HTML, javascript &amp; jQuery. I want to upload images to amazon s3 server in an ajax request. There is no such SDK to integrate s3 in Javascript. A PHP SDK is available, but it is not useful to me. Can anybody provide solution to this in javascript?

I have some text stored in a variable which contains some HTML.  For example, the &amp;lt;b&gt;cat&amp;lt;/b&gt; in the hat. However, when I render it in Jade, it shows up with the tags instead of rendering the formatting. How can I fix this?

Convert a directory structure in the filesystem to JSON with Node.js

npm allows us to specify [`bundledDependencies`](https://docs.npmjs.com/files/package.json#bundleddependencies), but what are the advantages of doing so? I guess if we want to make absolutely sure we get the right version even if the module we reference gets deleted, or perhaps there is a speed benefit with bundling?

Anyone know the advantages of `bundledDependencies` over normal dependencies?

I have multiple Node applications (build on Express framework).

Now I have placed them like this -

- `/var/www/app1`
- `/var/www/app2`
- `/var/www/app3`

Now I want to run these 3 apps on the same port (say 8080). Is that possible ?

One thing to note is that, Each app has common routes like these -

- `app.get(&#39;/&#39;, func...);`
- `app.get(&#39;/about&#39;, func...);`
- `app.post(&#39;/foo&#39;, func...);`
- `app.post(&#39;/bar&#39;, func...);`

Basically I want to do it like you can do with Apache/PHP setup.

So with a LAMP stack when you have -

- `/var/www/app1`
- `/var/www/app2`
- `/var/www/app3`

You can easily access them as different apps from -

- `localhost/app1`
- `localhost/app2`
- `localhost/app3`

Running multiple Node (Express) apps on same port

Say you want to install a library `lib-a` which has dependencies `dep-1` and `dep-2`. If `lib-a` has declared in its package.json to use a version of `dep-2` that is out of date (say it doesn&#39;t work on node 0.8.0 which just came out), but there is a branch of `dep-2` that works with node 0.8.0 - branch name `node0.8.0`.

So the packages in the equation are:

    git://github.com/user-a/lib-a
    git://github.com/user-b/dep-1
    git://github.com/user-c/dep-2
    git://github.com/user-c/dep-2#node0.8.0

Is there a way to tell NPM to install `lib-a`, but use `dep-2#node0.8.0` instead of `dep-2`?

With NPM you can install a specific branch of a project like this:

    npm install git://github.com/user-c/dep-2#node0.8.0

And if I were to customize the package.json of `lib-a`, you could tell it to use `dep-2#node0.8.0` like this:

    {
      &quot;name&quot;: &quot;lib-a&quot;,
      &quot;dependencies&quot;: {
        &quot;dep-1&quot;: &quot;&gt;= 1.5.0&quot;,
        &quot;dep-2&quot;: &quot;git://github.com/user-c/dep-2#node0.8.0&quot;
      }
    }

By modifying the package.json you can then run

    npm install lib-a

and it will install the node 0.8.0 compatible `dep-2` branch. But, that requires I have access to modifying `lib-a`, which for my specific case I don&#39;t. Technically, I could fork `lib-a` and make the above change to package.json. But in my specific case, `lib-a` is a dependency of _another_ library, so I&#39;d have to fork the project it&#39;s referenced in, and on and on...

So the question is, is there a way to tell NPM to install `lib-a`, and tell it to use the `node0.8.0` branch of `dep-2`? Something like this:

    npm install lib-a --overrides dep-2:git://github.com/user-c/dep-2#node0.8.0

That would be awesome. If it&#39;s not possible, that would be good to know so I can prepare myself to have to fork/customize the chain of projects.

When installing a package with NPM, can you tell it to use a different version of one of its dependencies?

I have a route on my Express app that looks like this:

    app.get(&#39;/:id&#39;, function (request, response) {
      …
    });

The ID will always be a number. However, at the moment this route is matching other things, such as `/login`. 

I think I want two things from this: 

1. to only use this route if the ID is a number, and 
2. only if there isn&#39;t a route for that specific paramater already defined (such as the clash with `/login`).

Can this be done?

How to I get rid of Jade while using Express with Node.JS? I want to just use plain html. In other articles I have seen that people recommended app.register() which is now deprecated in the latest version.

Using HTML in Express instead of Jade

I&#39;m working with Jade and Express and I would like to use a variable in my include statement. For example:

app.js

    app.get(&#39;/admin&#39;, function (req, res) {
      var Admin = require(&#39;./routes/admin/app&#39;).Admin;

      res.render(Admin.view, {
        title: &#39;Admin&#39;,
        page: &#39;admin&#39;
      });
    });

layout.jade

    - var templates = page + &#39;/templates/&#39;
    
    include templates

When I do this I get the error `EBADF, Bad file descriptor &#39;templates.jade&#39;`

I even tried

    include #{templates}

to no avail.


Use a variable in a Jade include

I am using a template as a base, and want it to be aware of some variables set in the page that is using it...

File: template.jade

    vars = vars || {some:&quot;variables&quot;}
    !!! 5
    head
        title vars.some

File: page.jade

    vars = {some:&quot;things&quot;} //- this does not get used from within template.jade
    extends template
    
I want the compiled page.jade to have a title &quot;things&quot;

how to pass variables between jade templates

Is there a way to do this inline in a jade template?

    if(typeof fromEdit != &#39;undefined&#39;)
       div#demo.collapse.in
    else
       div#demo.collapse

Would like to do this conditional check &quot;inline&quot; and the result would add the .in to the end of the div if fromEdit exists.

I need to include a javascript file to webpage. I write the following:

    (function($) {

as result. But I need:
