PrimeReact is a collection of rich UI components for React. PrimeReact is a sibling of the popular PrimeNG (Angular) and PrimeFaces (JSF) components suites.

A quick collection of all the fake Orly book covers I find around on the internet.

I am seriously considering writing content for the “Expert Excuses for Not Writing Unit Tests” one.

EDIT - I actually did write some content for it https://boyter.org/posts/expert-excuses-for-not-writing-unit-tests/

CSV & JSON convertor tool

This is a full-featured CSV parsing tool running entirely on your brower. No data leave your computer ! Use it also to learn how to use our packages and to test the various options interactively.

In shell, you can do it in many ways:

cat input | xargs echo | tr ' ' ,

or

perl -pe 's/\r?\n/,/' input > output

I know you wanted this to be longer, but I don't really see the point of writing multi line script to solve such simple task - simple regexp (in case of perl solution) is fully workable, and it's not something artificially shortened - it's the type of code that I would use on daily basis to solve the issue at hand.

Free Bootstrap Admin Template

The only Bootstrap Admin Template you need to create amazing user interfaces.

CoreUI is an open source Bootstrap 4 based admin template.

jq is like sed for JSON data - you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text.

jq is written in portable C, and it has zero runtime dependencies. You can download a single binary, scp it to a far away machine of the same type, and expect it to work.

jq can mangle the data format that you have into the one that you want with very little effort, and the program to do so is often shorter and simpler than you’d expect.

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.
