Readers may wonder, "Why get into coding a Node.js back end?" (Aside from the learning opportunity, of course.) "Isn't there already an app for that?" If that sounds daunting, the complete Node.js project will be presented at the end readers need only learn as much as they’re interested in learning, and there will be a fair number of gentler explanations of some basics along the way that more experienced readers can skip. It’s also a Node.js back-end tutorial: a chance to learn the basics of back-end JavaScript using the Express framework and the Pug (formerly Jade) template engine. That’s where this project comes in: The opportunity to transform any smartphone-even an old one that’s otherwise useless for lack of updates-into a handy remote for the next Netflix/YouTube/Amazon Prime Video/etc. While exercise is especially important right now, sometimes, there’s nostalgia for the luxury of a good, old-fashioned remote control when the laptop is beyond easy reach.

In the second line the paragraph content is a text string concatenated with the title variable. So for example, in the first line below, the content of the h1 tag will be variable title (either defined in the file or passed into the template from Express).

If a tag is followed by the equals sign, the following text is treated as a JavaScript expression. characters like " >" are converted to their HTML code equivalents like " >") to prevent JavaScript injection or cross-site scripting attacks. The values of all attributes are escaped (e.g.

meta(name='viewport' content='width=device-width initial-scale=1').

script(type='text/javascript'), link(rel='stylesheet', href='/stylesheets/style.css').

Inside the parentheses, the attributes are defined in comma- or whitespace- separated lists of the pairs of attribute names and attribute values, for example: H2 Generate a list ul each val in li = valĮlement attributes are defined in parentheses after their associated element. Strong focus on performance and powerful features. Pug is a terse and simple template language with a else p A variable named "title" does not exist. col if title p A variable named "title" exists. p = 'Evaluated and escaped expression:' + title // You can add single line JavaScript comments and they are generated to HTML comments //- Introducing a single line JavaScript comment with "//-" ensures the comment isn't rendered to HTML p A line with a link a ( href = '/catalog/authors' ) Some link text | and some extra text.
