Introduction to Nodejs (taking javascript to the server-side) - GeexHQ 0inShare Web Technologies so far Remeber those days when we used only the basic features of html to bring texts, images, tables and few other layouts into our webpage, Later CSS came into the picture and created a huge impact or it has actually influenced the way a normal web user-interface is made. After creating webpages & designs using markups and CSS, developers turned their focus onto the data transfer techniques, thats when Ajax came into the picture. Taking Javascript to the server-side As we see there are a lot of evolutions happening with the web, now developers have thought out of the box in making javascript more than just a client side programming language.There has been considerable interest in bringing javascript onto the server side as well, thanks to the CommonJS project. However, Node.js is a bit different from these solutions, because it is event-based rather than thread based. Featuring “nodeJs†and to start interactive mode use the command p>
Express.js From Wikipedia, the free encyclopedia JavaScript framework Express.js, or simply Express, is a back end web application framework for building RESTful APIs with Node.js, released as free and open-source software under the MIT License. History[edit] Express.js was founded by TJ Holowaychuk. In June 2014, rights to manage the project were acquired by StrongLoop. Features[edit] Robust routingConcentrate on high-performanceHTTP helpers (redirection, caching, etc) Popularity[edit] Express.js is used by Fox Sports, PayPal, Uber and IBM.[10] Example[edit] The following program will respond to HTTP GET requests with the text 'Hi, your request has been received', and listen to the port the program is running on; Port 2000, in this case.

Introducing Linked Data And The Semantic Web Next: Introducing Graph Data What is Linked Data and the Semantic Web and what is all the hype about? Principally, the Semantic Web is a Web 3.0 web technology - a way of linking data between systems or entities that allows for rich, self-describing interrelations of data available across the globe on the web. In essence, it marks a shift in thinking from publishing data in human readable HTML documents to machine readable documents. How Does It Differ From The Web As It Is Today? Today, much of the data we get from the web is delivered to us in the form of web pages - HTML documents that are linked to each other through the use of hyperlinks. Enter Linked Data - Liberating Web Databases From Their Old Chains The web contains lots of information, but typically the raw data itself isn't available - rather only HTML documents constructed from data, if a web site is generated from a database at all. But Where Do I Start? It needn't be complicated.
Why Developers Should Pay Attention to Node.js There's a substantial amount of buzz and enthusiasm right now about Node.js. So what is it, and why should you care about it (well, other than "I said so")? ReadWriteWeb chatted with Javascript developer Guillermo Rauch, co-founder and CTO of LearnBoost in order to get some insights. ReadWriteWeb: So, what is Node.js? ReadWriteWeb: Why should developers care? Rauch: First of all, most web developers are already using jQuery, MooTools, or similar frameworks to leverage JavaScript on the browser. Secondly, thanks to the expressiveness of JavaScript and the concise yet powerful Node.js API, you can build programs that have been typically considered out of reach or too time consuming. And lastly, you won't be alone. ReadWriteWeb: What are the key benefits of Node.js? Rauch: There are several: Fast. ReadWriteWeb: What are some of its drawbacks - and how do you respond to criticisms about Node.js? Rauch: It's incomplete. This is the only problem I see right now. Thanks, Guillermo!
Next.js Open-source web development framework React documentation mentions Next.js among "Recommended Toolchains" advising it to developers when "building a server-rendered website with Node.js".[5] Where traditional React apps can only render their content in the client-side browser, Next.js extends this functionality to include applications rendered on the server-side. The copyright and trademarks for Next.js are owned by Vercel,[6] which also maintains and leads its open-source development.[7] Background[edit] Google has contributed to the Next.js project, including 43 pull requests in 2019.[13] As of March 2022, the framework is used by many large websites, including Walmart, Apple, Nike, Netflix, TikTok, Uber, Lyft, and Starbucks.[9] In early 2020, Vercel secured twenty-one million dollars in Series A funding to support improvements to the software.[1] The framework's original author, Guillermo Rauch, is currently the CEO of Vercel, and the project's lead maintainer is Tim Neutkens.[14]
s Python Class - Educational Materials Welcome to Google's Python Class -- this is a free class for people with a little bit of programming experience who want to learn Python. The class includes written materials, lecture videos, and lots of code exercises to practice Python coding. These materials are used within Google to introduce Python to people who have just a little programming experience. To get started, the Python sections are linked at the left -- Python Set Up to get Python installed on your machine, Python Introduction for an introduction to the language, and then Python Strings starts the coding material, leading to the first exercise. This material was created by Nick Parlante working in the engEDU group at Google. Tip: Check out the Python Google Code University Forum to ask and answer questions.

What is RESTful API? - RESTful API Explained - AWS Representational State Transfer (REST) is a software architecture that imposes conditions on how an API should work. REST was initially created as a guideline to manage communication on a complex network like the internet. You can use REST-based architecture to support high-performing and reliable communication at scale. You can easily implement and modify it, bringing visibility and cross-platform portability to any API system. API developers can design APIs using several different architectures. The following are some of the principles of the REST architectural style: Uniform interface The uniform interface is fundamental to the design of any RESTful webservice. Uniform interface imposes four architectural constraints: Requests should identify resources. Statelessness In REST architecture, statelessness refers to a communication method in which the server completes every client request independently of all previous requests.

Google Developers This morning we welcomed 6,000 developers to our 7th annual Google I/O developer conference. The crowd in San Francisco was joined by millions more watching on the livestream and 597 I/O Extended events, in 90+ countries on six continents. We're meeting at an exciting time for Google, and for our developer community. There are now one billion of you around the world who use an Android device. One billion. Today, developers got a preview of our most ambitious Android release yet. But, beyond the mobile phone, many of us are increasingly surrounded by a range of screens throughout the day--at home, at work, in the car, or even on our wrist.
