The following list contains npm commands that I use practically every day while working with packages in my node.js projects:

It is a common practice that the text of the options of a select drop-down box is a combination of a shortcut and it’s full text label.

For example consider the following array of JSON objects that a server might return:

1
2
3

    {"shortcut": "GB", "label": "Great Britain"}
];

For my personal blog, which in based on Jekyll, I created a tag-area on the top of the homepage so that the visitors are able to navigate through the different articles in a tag-page by clicking on the tag that they are interested in. With this article I would like to present you the code of the tag-area:

<div class="well well-sm">Filter the articles:
    {% for tag in site.tags %}
        <a class="btn btn-warning" type="button" href="tags/{{ site.baseurl }}{{tag | first }}">
            {{ tag | first }} <span class="badge">{{ tag | last | size }}</span>
        </a>
    {% endfor %}
</div>
