I’m thrilled to announce the newest member of the Laravel ecosystem: Laravel Nova . Nova is a beautifully designed administration panel for Laravel. We’ve sweat the small details and carefully crafted Nova to not only look great, but to be a joy to work with.In this post, I’ll go over the key features of Nova; however, be sure to watch the recording of my Laracon talk for an in-depth demo of Nova’s features . Preface Nova is installed via Composer as a Laravel package. It doesn’t interfere with your existing application in any way. In fact, you can install Nova into existing Laravel 5.6 applications that you have already built.On the front-end, Nova is powered by Vue.js, Vue Router, and Tailwind.css. This makes for a powerful, flexible combination, especially in regards to customization — it’s a breeze to build custom tools, cards, and fields.Each Eloquent model in your application has a corresponding Nova “resource” class which defines its fields, actions, filters, lenses, and cards. Nova is configured entirely using simple PHP classes. No configuration is stored in the database. Resource Management Of course, a primary feature of Nova is the ability to create, read, update, and delete resources in your database. We have worked hard to cover all of the edge-cases in this regard. Need to update the data on the “intermediate / pivot” table of a polymorphic many-to-many relationship? We have you covered. Nova has wonderful support for all of the various Eloquent relationship types.Resource detail views give you instant access to a resource’s information, as well as its related resources — all with lightning fast search, pagination,...
The radical increase in mobile users has entailed the improvement of the mobile app industry. Mobile application development agencies help businesses in planning and designing exclusive and robust mobile apps that can fulfill the requirements of clients. People are depending more on mobile apps for performing daily jobs. And these applications consume lots of data. To assess and handle this data effectively, you need a unique data management tool. This is where big data analytics plays a role. It helps organizations get data-driven understanding from apps. What is Big Data? These days, tools, devices, and people create a diverse and dynamic volume of data. And this amount of data requires scalable, creative, enhanced, and new technology for analytics, hosting, and collection. The big data technology processes data gathered for deriving rich and real-time business information associated with productivity management, performance, profit, users, augmented shareholder value, and risk. Speed is the main factor in the world of Big Data. Generally, conventional analytics concentrates on the assessment of historical data, while, you can encompass the real-time data, using Big Data Analytics. Some top international brands that have used Big Data for boosting the operations of their organizations are: Netflix Capital One American Express Starbucks Amazon What is The Requirement Of Big Data In Mobile App Development? As per a Statista survey report, the global number of mobile application downloads is predicted to increase to 258.2 billion by 2022 and was 205 billion in 2018. This wide mobile app user base creates large volumes of raw data. Raw or unstructured type of data requires high-level analytics for testing the numbers and creating...
You may have come across Ruby on Rails, NodeJS, AngularJS, JavaScript, and perhaps the “MEAN” stack — MongoDB, ExpressJS, AngularJS, NodeJS — in your research of the different programming technologies. Newcomers will often gravitate towards learning only JavaScript — a single programming language — but it’s often mistaken as a shortcut to becoming a full-stack web developer. Yet, the “MEAN” stack can provide simpler solutions to a wider variety of problems. I frequently get asked questions like this: If I learn JavaScript and not the “MEAN” stack — MongoDB, ExpressJS, AngularJS, NodeJS — will web development be 4x easier for me? If I focus my time on JavaScript, will I be 4x better than any developer who uses those four technologies? It seems intuitive that we would be 4x better off as a full-stack JavaScript developer, but this is a common misconception. That’s okay, let’s explore why. Domain Specific Knowledge Learning JavaScript alone is not a fast track to full-stack web development. Learning only a programming language’s syntax — domain specific knowledge — doesn’t mean we’ll become a better full-stack web developer. Domain specific knowledge alone will make our skill progression a negligible amount easier in the grand scheme of any developer’s career. There is a better approach. Procedural Knowledge The smart way to becoming a full-stack web developer is by first learning how to figure out the things that we don’t know — procedural knowledge — and how to teach ourselves foreign concepts. If we want to make the long-term decision that will benefit the growth of our developer careers, we need to think of programming languages differently....
We are happy to have reached this milestone and thank you all for using our package over the last 6,5 years! Cheers to many more imports and exports! Laravel Excel 3.1.20 In other news, we have released Laravel Excel 3.1.20 with some improvements for running imports on Vapor and working with row numbers, along with some fixes and changes. You can find a write up about this new release here. New features Re-sycing remote temporary file When dealing with a multi server setup (and thus using a remote temporary file), it’s possible for the clean up that occurs after entire queue has been run to only cleanup the server that the last AfterImportJob runs on. The rest of the server would still have the local temporary file stored on it. In this case your local storage limits can be exceeded and future imports won’t be processed (This is especially an issue with Vapor). To mitigate this you can set the new config settings (force_resync_remote) to true. After every queued chunk the local temporary file will be deleted on the server that processed it. Without this setting it will only happen at the end of the process. Remember row number A new trait was added that helps keeping track of the current row number. This can be especially useful when dealing with the ToModel concern. You can get the current row number by using the `$this->rowNumber` property. Remember chunk offset In additional to the row number trait also a chunk offset trait was added. It keeps track of the start row of the current chunk. This can be especially helpful...
We live in a mobile-driven world. Tasks which earlier took several minutes or hours can now be fulfilled in the blink of an eye thanks to advanced app development services. The thriving mobility platform is evolved by leaps and bounds by implementing several features of emerging technologies like AR, VR, AI, IoT, and Blockchain. These technologies have made our life easier than before and brought revolutionary changes in the way we do business. In this article, we will discuss the role of Augmented Reality in mobile-app development. But before that, let’s highlight the basic concept of Augmented Reality. Augmented Reality is a simulation of the real world, which is made enhanced and more informative with the help of computer-generated incessant data, targeting multiple sensory systems like that of sight, hearing, olfactory (smell), haptic (grabbing), etc. The overall information can be both constructive (adding more data into the real-world) or can be destructive (masking data from the real world). Augmented Reality finds its application in varieties of sectors like the gaming industry, military for enhanced combat facilities, commercial sectors like education, travel & tourism, organizing meetings, etc. Let us now analyze the growing importance of Augmented Reality in mobile-app development. One of the most widely used implementations of AR concept is the development of Facial Recognition-based mobile applications. Users can readily access such apps as their face can act as a password. Another example is providing services based on facial recognition, like Lenskart, where the users can try any frame using the AR face recognition feature. Here, the frames are shown to the users after scanning their face. In this...
I’ve been playing with my new “CrowPi” from Elecrow. It’s a great Raspberrry Pi STEM kit that is entirely self-contained in a small case. It includes a touch screen and a TON of sensors, LCDs, matrix display, sensors, buzzers, breadboard, etc. NOTE: I talked to the #CrowPi people and they gave me an Amazon COUPON that’s ~$70 off! The coupon is 8EMCVI56 and will work until Jan 31, add it during checkout. The Advanced Kit is at https://amzn.to/2SVtXl2 #ref and includes everything, touchscreen, keyboard, mouse, power, SNES controllers, motors, etc. I will be doing a full review soon. Short review is, it’s amazing. I was checking out daily builds of the new open source .NET Core System.Device.Gpio that lets me use C# to talk to the General Purpose Input/Output pins (GPIO) on the Raspberry Pi. However, my “developer’s inner loop” was somewhat manual. The developer’s inner loop is that “write code, run code, change code” loop that we all do. If you find yourself typing repetitive commands that deploy or test your code but don’t write new code, you’ll want to try to optimize that inner loop and get it down to one keystroke (or zero in the case of automatic test). In my example, I was writing my code in Visual Studio Code on my Windows machine, building the code locally, then running a “publish.bat” that would scp (secure copy) the resulting binaries over to the Raspberry Pi. Then in another command prompt that was ssh’ed into the Pi, I would chmod the resulting binary and run it. This was tedious and annoying, however as programmers sometimes we...
