If a project has both an `.npmignore` and `.gitignore` file, npm will **only** use the `.npmignore` file.

From [the documentation](https://docs.npmjs.com/misc/developers#keeping-files-out-of-your-package):

&gt; Use a `.npmignore` file to keep stuff out of your package. If there&#39;s no `.npmignore` file, but there *is* a `.gitignore` file, then npm will ignore the stuff matched by the `.gitignore` file. If you *want* to include something that is excluded by your `.gitignore` file, you can create an empty `.npmignore` file to override it.

In simpler terms, npm *prefers* the `.npmignore` file if it is there, but will fall back to the `.gitignore` file.

In many cases, both Git and npm can ignore the same files, so it makes sense to just use a `.gitignore` file on its own. If there&#39;s ever a discrepancy (i.e. npm and Git need to ignore different files), then you need to maintain separate `.gitignore` and `.npmignore` files.

More information on what to put in `.npmignore` files: https://stackoverflow.com/questions/25124844/should-i-npmignore-my-tests

For anyone reading this trying to ignore a file/dir from git but wish to include it in npm publish and have tried using an empty `.npmignore` file with no luck. This works.

In your `.gitignore` file, add the file/dir you wish to exclude `**/build` for example and in your `.npmignore` file make sure you specify the same file/dir but with the `!` prefix so for the build example you would include `!**/build`

I am only using one line of jQuery in my application:

    $(&quot;div.printArea&quot;).printArea();

But this is giving me a Typescript error:

   &gt;The property &#39;printArea&#39; does not exist on type JQuery?

Can someone tell me how I can stop this error appearing?



How can I stop &quot;property does not exist on type JQuery&quot; syntax errors when using Typescript?

I want to be able to use two columns on one table to define a relationship. So using a task app as an example. 

**Attempt 1:**

    class User &lt; ActiveRecord::Base
      has_many :tasks
    end

    class Task &lt; ActiveRecord::Base
      belongs_to :owner, class_name: &quot;User&quot;, foreign_key: &quot;owner_id&quot;
      belongs_to :assignee, class_name: &quot;User&quot;, foreign_key: &quot;assignee_id&quot;
    end

So then `Task.create(owner_id:1, assignee_id: 2)`

This allows me to perform `Task.first.owner` which returns *user one* and `Task.first.assignee` which returns *user two* but `User.first.task` returns nothing. Which is because task doesn&#39;t belong to a user, they belong to *owner* and *assignee*. So,

**Attempt 2:**


    class User &lt; ActiveRecord::Base
      has_many :tasks, foreign_key: [:owner_id, :assignee_id]
    end

    class Task &lt; ActiveRecord::Base
      belongs_to :user
    end

That just fails altogether as two foreign keys don&#39;t seem to be supported. 

So what I want is to be able to say `User.tasks` and get both the users owned and assigned tasks. 

Basically somehow build a relationship that would equal a query of `Task.where(owner_id || assignee_id == 1)`

Is that possible?

# Update
I&#39;m not looking to use `finder_sql`, but this issue&#39;s unaccepted answer looks to be close to what I want: https://stackoverflow.com/questions/3421873/rails-multiple-index-key-association

So this method would look like this,

**Attempt 3:**

    class Task &lt; ActiveRecord::Base
      def self.by_person(person)
        where(&quot;assignee_id =&gt; :person_id OR owner_id =&gt; :person_id&quot;, :person_id =&gt; person.id
      end 
    end

    class Person &lt; ActiveRecord::Base

      def tasks
        Task.by_person(self)
      end 
    end

Though I can get it to work in `Rails 4`, I keep getting the following error:

    ActiveRecord::PreparedStatementInvalid: missing value for :owner_id in :donor_id =&gt; :person_id OR assignee_id =&gt; :person_id

I have a file that is generated by `npm install` command (using `preinstall` task). I don&#39;t want to add it in the git repository, nor in the NPM project.

Supposing the file name is `foo.json`, I added it in `.gitignore` file as `foo.json`.

Is this enough to avoid uploading it on NPM registry?

I know I can add `.npmignore` file that will surely ignore the file, but I won&#39;t add it if `.gitignore` already does this.

Does NPM ignore files listed in .gitignore?

Tl;Dr - The Question:
-----------------

**What is the right way to handle streaming a video file to an html5 video player with Node.js *so that the video controls continue to work?***

I *think* it has to do with the way that the headers are handled. Anyway, here&#39;s the background information. The code is a *little* lengthy, however, it&#39;s pretty straightforward.

Streaming small video files to HTML5 video with Node is easy
-----------------------------------

[I learned how to stream small video files to an HTML5 video player very easily.][1] With this setup, the controls work without any work on my part, and the video streams flawlessly. A working copy of the fully working code with sample video is [here, for download on Google Docs][2].

**Client:**
    
    &lt;html&gt;
      &lt;title&gt;Welcome&lt;/title&gt;
        &lt;body&gt;
          &lt;video controls&gt;
            &lt;source src=&quot;movie.mp4&quot; type=&quot;video/mp4&quot;/&gt;
            &lt;source src=&quot;movie.webm&quot; type=&quot;video/webm&quot;/&gt;
            &lt;source src=&quot;movie.ogg&quot; type=&quot;video/ogg&quot;/&gt;
            &lt;!-- fallback --&gt;
            Your browser does not support the &lt;code&gt;video&lt;/code&gt; element.
        &lt;/video&gt;
      &lt;/body&gt;
    &lt;/html&gt;

**Server:**

    // Declare Vars &amp; Read Files

    var fs = require(&#39;fs&#39;),
        http = require(&#39;http&#39;),
        url = require(&#39;url&#39;),
        path = require(&#39;path&#39;);
    var movie_webm, movie_mp4, movie_ogg;
    // ... [snip] ... (Read index page)
    fs.readFile(path.resolve(__dirname,&quot;movie.mp4&quot;), function (err, data) {
        if (err) {
            throw err;
        }
        movie_mp4 = data;
    });
    // ... [snip] ... (Read two other formats for the video)

    // Serve &amp; Stream Video

    http.createServer(function (req, res) {
        // ... [snip] ... (Serve client files)
        var total;
        if (reqResource == &quot;/movie.mp4&quot;) {
            total = movie_mp4.length;
        }
        // ... [snip] ... handle two other formats for the video
        var range = req.headers.range;
        var positions = range.replace(/bytes=/, &quot;&quot;).split(&quot;-&quot;);
        var start = parseInt(positions[0], 10);
        var end = positions[1] ? parseInt(positions[1], 10) : total - 1;
        var chunksize = (end - start) + 1;
        if (reqResource == &quot;/movie.mp4&quot;) {
            res.writeHead(206, {
                &quot;Content-Range&quot;: &quot;bytes &quot; + start + &quot;-&quot; + end + &quot;/&quot; + total,
                    &quot;Accept-Ranges&quot;: &quot;bytes&quot;,
                    &quot;Content-Length&quot;: chunksize,
                    &quot;Content-Type&quot;: &quot;video/mp4&quot;
            });
            res.end(movie_mp4.slice(start, end + 1), &quot;binary&quot;);
        }
        // ... [snip] ... handle two other formats for the video
    }).listen(8888);

But this method is limited to files &lt; 1GB in size. 

&lt;!-- groups.google.com/forum/#!topic/nodejs/BQ5dSm8lITQ --&gt;

Streaming (any size) video files with `fs.createReadStream`
------------------------------------------------------------------------

By utilizing `fs.createReadStream()`, the server can read the file in a stream rather than reading it all into memory at once. This sounds like the right way to do things, and the syntax is extremely simple:

**Server Snippet:**

    movieStream = fs.createReadStream(pathToFile);
    movieStream.on(&#39;open&#39;, function () {
        res.writeHead(206, {
            &quot;Content-Range&quot;: &quot;bytes &quot; + start + &quot;-&quot; + end + &quot;/&quot; + total,
                &quot;Accept-Ranges&quot;: &quot;bytes&quot;,
                &quot;Content-Length&quot;: chunksize,
                &quot;Content-Type&quot;: &quot;video/mp4&quot;
        });
        // This just pipes the read stream to the response object (which goes 
        //to the client)
        movieStream.pipe(res);
    });
    
    movieStream.on(&#39;error&#39;, function (err) {
        res.end(err);
    });

This streams the video just fine! But the video controls no longer work.

So, I want my first level catch to be the one that handles the error. Is there anyway to propagate my error up to that first catch?

Reference code, not working (yet):

	Promise = require(&#39;./framework/libraries/bluebird.js&#39;);

	function promise() {
		var promise = new Promise(function(resolve, reject) {
			throw(&#39;Oh no!&#39;);
		});

		promise.catch(function(error) {
			throw(error);
		});
	}

	try {	
		promise();
	}
	// I WANT THIS CATCH TO CATCH THE ERROR THROWN IN THE PROMISE
	catch(error) {

In Bluebird&#39;s [`util.js` file](https://github.com/petkaantonov/bluebird/blob/7454401269cfa47e5b001354388c062509103de7/src/util.js#L180), it has the following function:

    function toFastProperties(obj) {
        /*jshint -W027*/
        function f() {}
        f.prototype = obj;
        ASSERT(&quot;%HasFastProperties&quot;, true, obj);
        return f;
        eval(obj);
    }

For some reason, there&#39;s a statement after the return function, which I&#39;m not sure why it&#39;s there.

As well, it seems that it is deliberate, as the author had silenced the JSHint warning about this:

&gt; Unreachable &#39;eval&#39; after &#39;return&#39;. (W027)

What exactly does this function do? Does `util.toFastProperties` really make an object&#39;s properties &quot;faster&quot;?

I&#39;ve searched through Bluebird&#39;s GitHub repository for any comments in the source code or an explanation in their list of issues, but I couldn&#39;t find any.

How does Bluebird&#39;s util.toFastProperties function make an object&#39;s properties &quot;fast&quot;?

It seems like you can do just about everything else directly on GitHub using the web interface, like edit and create and delete files, but I am unable to find a way to revert a commit, like you can in the GitHub local apps (Windows, and Mac) and like you can do on the git command line.

I&#39;m just wondering am I just missing something. Is the revert button hidden?

I tried searching online and came across something that seemed to suggest that this was to prevent synchronization errors when working with lots of people. Is this correct?

I was attempting to upgrade `phonegap` via `npm` when I started running into trouble. Long story short, there are two `node_modules` directories on my computer.

    /usr/local/lib/node_modules
    /usr/local/share/npm/lib/node_modules

When I run `npm upgrade -g phonegap`, it appears that `npm` updates the copy of the package that resides in `/usr/local/lib/node_modules`. However, if I `which phonegap` I find that the symlink points to the older installation at `/usr/local/share/npm/lib/node_modules`.

Also, when I attempt to install a stand alone package such as `express`, the files are installed in the `/usr/local/lib/node_modules` directory, &lt;strike&gt;but no symlink to the executable is created in anywhere in my `$PATH`.&lt;/strike&gt;

Two questions:

 - Which is the proper directory for node modules on Mac OS X?
 - &lt;strike&gt;How can I configure `npm` to link executables in my `$PATH` when it installs software?&lt;/strike&gt;

Bonus points: Does the method of installing `node` affect the configuration? There are a [lot of options][1].

&lt;hr&gt;

**EDIT**: I figured out that symlinks were being created in my `/usr/local/bin`, but my `.bash_profile` was setup with `/usr/local/share/npm/bin` ahead of `/usr/local/bin` in my `$PATH`. I vaguely remember adding that path to my profile at some point, but I&#39;m not sure why.

So the question now becomes: how did I end up with two different `node_modules` directories on my computer and why would I want to have my `node_modules` in the `share/npm/lib` subdirectory instead of right in `/usr/local/lib`?
