The goal of the project is to allow you to write awesome modern ES6 Javascript taking advantage of classes, decorators, arrow functions, and best of all, many of the vast array of NPM packages available using the standard ES6 module imports. You can then take that code and use in directly from QML, just as you would with plain, old, QML-specific Javascript. You can even build a library using ES6 and NPM packages, and then distribute that as a standard QML module or QPM package for other developers to use in regular QML or QML-specific Javascript. For those who would prefer to stick with standard QML-specific Javascript, you can also do that and still use the Quickly library, which gives you promises, the fetch API, and many polyfills. This is great for longtime QML devel- opers or existing projects that just want to drop in some easy-to-use features from modern JS core libraries.

  • Npm Packages As Ingredients: a Recipe-Based Approach
    npm Packages as Ingredients: a Recipe-based Approach Kyriakos C. Chatzidimitriou, Michail D. Papamichail, Themistoklis Diamantopoulos, Napoleon-Christos Oikonomou, and Andreas L. Symeonidis Electrical and Computer Engineering Dept., Aristotle University of Thessaloniki, Thessaloniki, Greece fkyrcha, mpapamic, thdiaman, [email protected], [email protected] Keywords: Dependency Networks, Software Reuse, JavaScript, npm, node. Abstract: The sharing and growth of open source software packages in the npm JavaScript (JS) ecosystem has been exponential, not only in numbers but also in terms of interconnectivity, to the extend that often the size of de- pendencies has become more than the size of the written code. This reuse-oriented paradigm, often attributed to the lack of a standard library in node and/or in the micropackaging culture of the ecosystem, yields interest- ing insights on the way developers build their packages. In this work we view the dependency network of the npm ecosystem from a “culinary” perspective. We assume that dependencies are the ingredients in a recipe, which corresponds to the produced software package. We employ network analysis and information retrieval techniques in order to capture the dependencies that tend to co-occur in the development of npm packages and identify the communities that have been evolved as the main drivers for npm’s exponential growth. 1 INTRODUCTION Given that dependencies and reusability have be- come very important in today’s software develop- The popularity of JS is constantly increasing, and ment process, npm registry has become a “must” along is increasing the popularity of frameworks for place for developers to share packages, defining code building server (e.g.

  • Building-Frontend-Pipeline Short
    Building a Frontend Pipeline Nathaniel T. Schutta @ntschutta Ah JavaScript! It used to be so simple right? 1,500 line main.js. Our apps aren’t like that anymore though are they? JavaScript is a first class citizen now. Modern applications are many thousands of lines of JavaScript. We incorporate many libraries and frameworks. https://mobile.twitter.com/joeerl/status/930774515512201216 NPM all the things. JavaScript itself is evolving. Browsers are still an issue… The struggle is real. What do we do about it? Why do we need a pipeline at all? Not your older sister’s web apps. No longer a few thousands lines of JavaScript and jQuery. Adhoc approach can’t keep up with the complexity of modern JS apps. Apply the level of discipline to the frontend that we use on the backend. Linters to ensure our code doesn’t fall prey to common errors. Unit tests to ensure our changes didn’t break anything. Bundlers to minimize asynchronous requests to our servers. Transpilers so we can leverage ES6 in older browsers. Task runers to help tie it all together. JavaScript usage has exploded. Number one language on GitHub? Yep. Not a new phenomena either. We cannot afford to treat JavaScript as a one off. The same engineering discipline we use on “server side” code must apply. Of course for many of us, JavaScript *is* our server side language too! More than a few options. Try and clear some of that up today. Linters. Certain mistakes can be caught automatically. Static code analysis. Find bad patterns. Check style adherence.

These are the steps you’ll need to follow: 1. Setting up npm 2. Writing your mutation 3. Setting up Webpack 4. Publishing your mutation to npm Mutations allow our users to have ultimate flexibility with their note taking styles. A mutation can change most aspects of Aurora. For instance, if you like taking notes in a cornell style format, you can write a mutation that will allow you to do that. Don’t like the way the previews look? You can write a mutation to change that. 1.1 Plugins as NPM Packages First you’ll need to install node if you don’t already have it. That can be done with this link: node download Node comes with a version of npm, but you will need to check if it is the latest version. That can be done with entering this command in your terminal npm install npm@latest -g To test if it updated enter the command npm -v The version should be higher than 2.1.8 Once you have npm downloaded and updated you can then you can start creating your mutation.

Marshall Space Flight Center (MSFC) Marshall Space Flight Center Alabama 35812 for Management and Display of Four-Dimensional ' Environmental Data Sets Using blcIDAS Contract _NAS8-36292 University of Wisconsin Account #144X669 for the period of 2/28/86 thru 8/31/90 submitted by William L. Hibbard David Santek Verner E. Suomi Space Science and Engineering Center at the University of Wisconsin - Madison 1225 West Dayton Street Madison, Wisconsin 53706 (608) 262-0544 November 1990 v I. INTRODUCTION Over the past four years, great strides have been made in the areas of data management and display of 4-D meteorological data sets. When the current contract went into effect in early 1986, the displays consisted of wind trajectories and moisture mesh surfaces from upper air data over a topographical map. Now the software can produce multi-parameter displays of transparent surfaces, trajectories as streamers, density surfaces, 2-D contours and text, in stereo or mono (with color). Also, we have made the move from single image processing on the mainframe computer to real-time interaction on the Stardent computer. This report summarizes the work accomplished under this contract with details contained in the appendices. II. WORK SUMMARY The Statement of Work for this contract read as follows: TASK 1: Inventory of 4-dimensional data setr. Survey of available and planned 4-D meteorological data sources.
