Node.js allows building scalable server-side applications using JavaScript. Node.js® is a JavaScript runtime built on Chrome’s V8 JavaScript engine. Node.js is an open-source, cross-platform, runtime environment that enables developers to write server-side applications in javascript. So Let’s start with some important concepts of Node – Express app with an introduction of Node.js. Here we will start our discussion by building an understanding of Nodejs concepts like what is node.js? How does node.js work? its benefits and then create our app. I will provide a step by step detailed guide with examples and a required screenshot of code which will help you to understand the code and concepts. What do you think?īTW no incentive was received for this post – I just love this cool little app.In this article, you will learn how to create your first Node.js app with Express. Here’s the result – not the best photo as it was taken on the fly and I wasn’t thinking of a blog post at the time. I sent my first postcard from Turkey which was delivered within 48 hours – the first time a postcard has arrived before me! The card was great quality good depth of colour and not at all flimsy. Paypal or credit card can be used or you can add credit to your account on-line. The cost is 99p per card to anywhere in the world – pretty good value when a first class stamp in the UK is currently 60p. Step 2 – Add your message and the address which you can choose from your contact list or add manually. Here’s the shot I chose which I’d taken on my phone – bit pleased with this one! Step 1 – Either take a photo or use one from your camera roll Here’s how it works…ĭownload the app to your phone (the app itself is free) and start creating your bespoke postcard.
So, when I discovered a nifty little app for i-phone, called By Post, where you can design a postcard on your i-phone, using your own photo, and send it anywhere in the world for just 99p – all within a couple of minutes – I had to give it a go. I’ve sent postcards that have arrived after I’ve returned to the UK and left again on my next trip or they’ve never arrived at all – where do those lost postcards go? It’s generally not a problem buying the card but finding a stamp and then locating a post-box can be a bit of a pain. Do you send postcards? I always try to send one to my parents when I travel – they love receiving them and it’s great going through the stash of cards that I’ve sent them over the years – the message on the back can bring back memories that the picture on the front doesn’t always trigger…īut sending a postcard can sometimes be a hassle.
