API-based projects are more and more popular, and they are pretty easy to create in Laravel. But one topic is less talked about – it’s error handling for various exceptions. API consumers often complain that they get “Server error” but no valuable messages. So, how to handle API errors gracefully? How to return them in “readable” form? Main Goal: Status Code + Readable Message For APIs, correct errors are even more important than for web-only browser projects. As people, we can understand the error from browser message and then decide what to do, but for APIs – they are usually consumed by other software and not by people, so returned result should be “readable by machines”. And that means HTTP status codes. Every request to the API returns some status code, for successful requests it’s usually 200, or 2xx with XX as other number. If you return an error response, it should not contain 2xx code, here are most popular ones for errors: Status Code Meaning 404 Not Found (page or other resource doesn’t exist) 401 Not authorized (not logged in) 403 Logged in but access to requested area is forbidden 400 Bad request (something wrong with URL or parameters) 422 Unprocessable Entity (validation failed) 500 General server error Notice that if we don’t specify the status code for return, Laravel will do it automatically for us, and that may be incorrect. So it is advisable to specify codes whenever possible. In addition to that, we need to take care of human-readable messages. So typical good response should contain HTTP error code and JSON result with something like this: Ideally,...
We all are diving in the world of Smartphones and tablets. The backbone of these gadgets are –applications, which in general known as – Mobile apps. Mobile apps provide a lot of benefits to the end-users and organizations. Business owners are delivering apps for different purposes such as – customer awareness, revenue generation, workforce productivity etc. This leads to emerging demands of mobile applications and app development companies as well. Every unit of a development firm is capable and up-to-date with the latest concepts and app development trends. For the sake of all of you, we prepared a list of all the latest trends that describe the future of mobile app development. Let’s have a look – 1. IoT( Internet of things ) IoT stands for ‘Internet of Things’. It is a technology responsible for connecting physical objects with the smartphone or each other to communicate. From past some years, mobile app development is very much into IoT because of its advanced functionalities. The use of IoT is very common nowadays in electrically controlled devices. You can control these devices just with the help of your smartphone. No physical interaction required. For example, if you forgot to switch off your AC after coming out of the house, you don’t need to go there. You can turn off it with the help of your smartphone. 2. AI and Machine Learning Artificial intelligence was already booming in 2017. In 2018, it is the most common trend in app development. Brands are optimizing artificial intelligence and machine learning in their web-apps and mobile apps. The AI-powered apps can accomplish tedious tasks. Users love...
Penetration testing is becoming increasingly common as organizations are starting to embrace the requirement for stronger cybersecurity. But there are yet too many businesses that don’t understand the benefits of regular security testing. Penetration testing is vital for any kind of organization with an IT system or website. A recent survey of penetration testers reported that 88 percent of those questioned stated they could infiltrate companies and steal data within 12 hours. This explains that almost all businesses are likely to be exposed to attacks. But many people do not know what a Penetration test includes particularly the types of vulnerabilities that testing benefits to identify. In truth, there are many various types of Penetration testing, and the results can depend mainly on which type you have carried. What Is A Penetration Test? A penetration test comprises a team of security professionals who actively try to break into your company’s network by using weaknesses and vulnerabilities in your systems. Penetration tests may involve any of the following purposes: Using social engineering techniques to enter systems and related databases. Sending of phishing emails to reach critical accounts. Using unencrypted passwords distributed in the network to reach sensitive databases. These attempts can be very intrusive than a vulnerability scan and may cause a rejection of service or increased system utilization, which may decrease productivity, and damage the machines. In some instances, you may schedule penetration tests and notify staff in advance of the exercise. However, this wouldn’t be suitable if you want to examine how your internal security team reacts to a “live” threat. A penetration test can decide if certain...
By Jess Feldman Last Updated December 15, 2020 Professional musician Léo McKenna relied on odd jobs and performances to pay the bills. When the COVID-19 lockdown threw Léo’s financial stability into limbo, he turned to . Léo shares how ’ 12-week, remote web development bootcamp provided him with a new sense of purpose, and why he now feels confident about his future as a developer-musician. Plus, Léo answers the age-old question: do musicians and performing artists make great developers? As a professional musician, what inspired you to get into web development? I’ve been devoted to music since I was eight years old and I have worked professionally in choirs since I was 18, but a career in the arts is financially precarious. That said, I don’t see myself ever leaving the field permanently. I’ve done odd jobs trying to supplement my income as a bartender, mover, server, you name it! When the pandemic hit this year, it negatively impacted arts organizations and I lost my job. I’m currently studying music performance at McGill University, but I’ve always been interested in computers and programming — I just never had time to pursue that interest until now. When the pandemic hit, I jumped on the opportunity to add to my skill set. I now plan to work full-time as a developer until I complete my music training and I can pay off my student debt. There are so many coding bootcamps now — why did you choose ? Lighthouse Labs focuses on JavaScript whereas other bootcamps focus more Ruby on Rails. My mother works as a project manager and some of...
Node.js or as commonly called NodeJS, is an open source , cross platform Java Run time environment based Chrome’s V8 JavaScript engine, meant for server-side programming. It allows us to run scripts on server-side to produce dynamic web page content before the page is sent to the user’s web browser. It allows to easily develop networked applications that require back-end functionality with Java-scripts being used on both front-end & back-end. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. In this tutorial, we will learn to install Node.JS on Ubuntu & CentOS machines. (Recommended Read: – ) Pre-requisites We need to have some packages like ‘gcc, gcc-c++’ installed on our systems. Install them on CentOS using the following command, $ sudo yum install gcc gcc-c++ For Ubuntu, install them using the following command, $ sudo apt-get install build-essential Install NodeJS on Ubuntu We can install either of the two available Node.JS versions i.e. 6 (which has long term support) or 9 (which is the latest version available). For installing Node.JS, we will add the official repositories on our system, use the following command to add the repository, For Node.JS 6, $ curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash – For Node.JS 9, $ curl -sL https://deb.nodesource.com/setup_9.x | sudo -E bash – Once added, install Node.JS using the following command, $ sudo apt-get install nodejs We can also install Node.JS using the source code, method has been discussed below. Install NodeJS on CentOS On CentOS, we can either install Node.JS from EPEL repository or from official Node.JS repositories. Both methods have been shared below. Using EPEL...
