Generate Cold Storage Paper Wallets For Ripple XRP Coins With Angular

About a week ago I wrote about Ripple in a tutorial titled, Build a Ripple XRP Wallet for Android and iOS with Ionic Framework, which focused on mobile development as a followup to a cross-platform desktop application that I had written about before that.

There are many who would advise against storing sensitive wallet information on a computer or anything connected to the internet. As an alternative, people recommend printing your transaction signing information such as private keys and storing them on what’s called a paper wallet, destined for a locked safe in your home or the bank.

We’re going to see how to create a paper wallet for Ripple XRP coins using Angular and some packages provided by the Ripple development team.

Send And Manage DigiByte DGB Coins With Node.js

I’ve been spending a lot of time researching and watching the blockchain market because it is a very interesting subject matter. Not too long ago I had written an article titled, Create a Cross-Platform Desktop Ripple XRP Wallet with Vue.js and Electron, which focused on the Ripple, the banking network and cryptocurrency.

Ripple isn’t the only cryptocurrency that I’m following. I’m also following DigiByte, which targets digital payments and has the DGB coin. If you’re not familiar with DigiByte, the official wallet forces you to download around 12GB of data to synchronize with the network. It isn’t really appealing to anyone who just wants to sit on some DGB. The good news, is this can be avoided by building your own wallet and client.

We’re going to see how to build a DigiByte DGB client for storing, sending, and managing coins without having to synchronize with the network, using JavaScript and Node.js.

Build A Ripple XRP Wallet For Android And iOS With Ionic Framework

A few days ago I released, what turned out to be, a very popular article around developing a Ripple XRP wallet. It was titled, Create a Cross-Platform Desktop Ripple XRP Wallet with Vue.js and Electron, and it focused on cross-platform desktop application development. A popular request on Twitter was around developing a mobile Android and iOS wallet for Ripple XRP coins.

We’re going to see how to use Ionic Framework and Angular to create a Ripple XRP wallet for Android and iOS. Because our desktop application focused on the JavaScript stack, our mobile application will be able to recycle a lot of our code.

Create A Cross-Platform Desktop Ripple XRP Wallet With Vue.js And Electron

As you are probably aware, I’ve been interested in cryptocurrency and the blockchain lately. I haven’t necessarily been buying anything, but I’ve been doing a lot of watching as it has all been very interesting so far.

I decided, a few weeks ago, to purchase some Ripple (XRP) because it seems like it could do great things for the banking industry. When it came to keeping track of my XRP, there wasn’t really anything available. There is Ripple Wallet, but after having used it for a little bit, it seemed buggy. That got me thinking. What if I were to build my own wallet?

Ripple actually released a Node.js library called ripple-lib on GitHub which makes it very easy to interact with XRP. What makes things even better is that the cross-platform desktop application framework, Electron, uses Node.js.

We’re going to see how to create a cross-platform desktop application using Node.js, Vue.js, and Electron to keep track of our Ripple and how much our wallet is worth.

My Activity Report For 2017

This marks the third year that I’ve been producing content for The Polyglot Developer and all of its channels. It’s been a long year and I’ve accomplished a lot, some of which was different than previous years.

Below you’ll find my statistics that may help you if you’re planning on creating a blog or developing a course. It will give you an idea of costs and what to expect.

Deploying Native Node.js Dependencies On AWS Lambda

I was recently working on a Functions as a Service (FaaS) project using AWS Lambda and Node.js. However, I was running into an issue where my package dependencies found in my node_modules directory were for the wrong platform once deployed to Lambda. This is not the first time I experienced a problem like this. I knew the issue straight away because I encountered the same thing when trying to use a node_modules directory generated on Mac from a Windows computer.

When uploading a package developed with Node.js to AWS Lambda, the package.json file is not considered. Instead you are uploading a package that contains the node_modules directory and all dependencies. So how do you develop for AWS Lambda from Mac and Windows, but have it work once deployed?

We’re going to see how to use Docker to get our Node.js FaaS project dependencies designed for Amazon’s flavor of Linux.

Convert A Node.js RESTful API To Serverless With OpenWhisk

When it comes to serverless solutions, there are many options available. If you’re a fan of the Microsoft cloud, you could create Azure Functions. If you’ve been keeping up, I wrote a tutorial called, Take a Node.js with Express API Serverless Using AWS Lambda, which used the Amazon Web Services cloud. Another solution is Apache OpenWhisk, a solution available on IBM’s Bluemix cloud.

We’re going to see how to convert the Node.js with Express application that I had written about in a previous article, and make it serverless with OpenWhisk.
