Insomnia is a free cross-platform desktop application that takes the pain out of interacting with HTTP-based APIs. Insomnia combines an easy-to-use interface with advanced functionality like authentication helpers, code generation, and environment variables.

Passport is authentication middleware for Node.js. Extremely flexible and modular, Passport can be unobtrusively dropped in to any Express-based web application. A comprehensive set of strategies support authentication using a username and password, Facebook, Twitter, and more.

HTTP assertions made easy via superagent.

The motivation with this module is to provide a high-level abstraction for testing HTTP, while still allowing you to drop down to the lower-level API provided by superagent.

Using Javascript on the server side like that requires that you use callbacks. You cannot "return" them like you want, you can however write a function to perform actions on the results.

sequelize.query(query).success(function(row) {
    // Here is where you do your stuff on row
    // End the process
    process.exit();
}

A more practical example, in an express route handler:

// Create a session
app.post("/login", function(req, res) {
    var username = req.body.username,
        password = req.body.password;
    // Obviously, do not inject this directly into the query in the real
    // world ---- VERY BAD.
    return sequelize
      .query("SELECT * FROM users WHERE username = '" + username + "'")
      .success(function(row) {
          // Also - never store passwords in plain text
          if (row.password === password) {
              req.session.user = row;
              return res.json({success: true});
          }
          else {
              return res.json({success: false, incorrect: true});
          }
      });
});

Ignore injection and plain text password example - for brevity.

Functions act as "closures" by storing references to any variable in the scope the function is defined in. In my above example, the correct res value is stored for reference per request by the callback I've supplied to sequelize. The direct benefit of this is that more requests can be handled while the query is running and once it's finished more code will be executed. If this wasn't the case, then your process (assuming Node.js) would wait for that one query to finish block all other requests. This is not desired. The callback style is such that your code can do what it needs and move on, waiting for important or processer heavy pieces to finish up and call a function once complete.

EDIT

The API for handling callbacks has changed since answering this question. Sequelize now returns a Promise from .query so changing .success to .then should be all you need to do.

WebPerl uses the power of WebAssembly and Emscripten to let you run Perl in the browser!

WebPerl does not translate your Perl code to JavaScript, instead, it is a port of the perl binary to WebAssembly, so that you have the full power of Perl at your disposal!

<script src="webperl.js"></script>
<script type="text/perl">

print "Hello, Perl World!\n";  # goes to JavaScript console by default

js('document')->getElementById('my_button')
    ->addEventListener('click', sub {
        js('window')->alert("You clicked the button!");
    } );
</script>

Analyze and debug JavaScript (or Sass or LESS) code bloat through source maps.

The source map explorer determines which file each byte in your minified code came from. It shows you a treemap visualization to help you debug where all the code is coming from.

We help developers, and the companies they work for, stay up-to-date via our variety of publications, across the web, social and by email.

meson press publishes research on digital cultures and networked media. Our open access publications challenge contemporary theories and advance key debates in the humanities of today.

We combine a rigorous peer-review with hybrid formats and collaborative production methods. As a cooperative, meson press is organized in a participated setup. This allows scholars to take part in a publishing venture by academics for academics and for everyone else who is curious about theory.

In the hybrid environment of today’s scholarly publishing, form follows function in a new manner. meson press books take pride in the haptic elegance of print and are designed to transfer this to a digital set-up. To ensure this, our print and digital editions have been developed in collaboration with the Berlin based book and web designers Torsten Köchlin and Silke Krieg.

meson press books are printed on-demand and distributed worldwide to be available far beyond Europe including the UK, US, and South America. Our digital editions are available for free download on the internet. To ensure the authors’ rights as well as the openness of published monographs, meson press is committed to publish under a Creative Commons CC-BY-SA license if possible.

meson press is a cooperative initiated by Mercedes Bunz, Marcus Burkhardt and Andreas Kirchner, and grew out of the Hybrid Publishing Lab, Leuphana University of Lüneburg that looked into the effects of digitalization on academic communication and publishing.
