While deploying an app recently, I experienced many frustrations with the various nuances that accompany deployment, most of which were made even more difficult by the lack of centralized information about it online. Of course, this is a result of the many ways that deployment can be done (meaning that this guide is only one way to do things).This guide is designed to be a start to finish guide for someone creating a React single page application using DigitalOcean, with every important detail. We’ll serve it with #nginx as a reverse proxy (and explain why you want to do this), PM2 as a process manager, and Serve to actually handle the serving of the app. Most of the concepts here with regards to setting up your DigitalOcean server are transferrable to the #aws EC2 platform once you have (...)

This is a short tutorial article on how to read the serial port values from arduino to in NodeJS.MotivationSo, there was a project I was working on where I had to fetch the data from serial monitor in my node console and then using web sockets display the data in a web based application. But, I was having a hard time figuring out how to fetch the data, I explored and found serialport npm module, but the output it gave was in form of buffer, not the exact word I wanted. After spending some time, I was able to figure out how to do it. Hence, I am sharing this so that it can help anyone who is trying to do the same.How does arduino and other peripherals communicate with Laptop?In most of the cases, the answer is “Serial Communication”.

What is RedisRedis is an in-memory data structure store which can be used as a #database, a cache and a message broker. Redis supports different data structures such as strings, lists, sets, hashes, bitmaps and etc. . Simply Redis uses you RAM to store data which is very fast, however if you reboot your server the values are gone, unless you enable Redis persistence. Good news by default Redis enables persistence mechanism for you (you can disable or configure persistence according to your needs.)Install Redis (Linux)Refer: ▻https://redis.io/downloadDownload, extract and compile Redis with:$ wget ▻http://download.redis.io/releases/redis-4.0.9.tar.gz$ tar xzf redis-4.0.9.tar.gz$ cd redis-4.0.9$ makeThe binaries that are now compiled are available in the src directory.

Here’s a problem you might run into while using React Native: Let’s say you want to use the crypto module to create some hashes. It might seem natural to do something like this:▻https://medium.com/media/68d54b356fea87b72ea19a1aa7b00233/hrefBut this doesn’t work, because crypto is a core Node JS module, which means it’s probably C++ code bundled with the Node JS binary, not #javascript. The React Native packager can’t package it[1] along with your app’s Javascript bundle, so you get a runtime error: Unable to resolve module ’crypto’.This makes core modules like crypto, stream etc. and the thousands of npm modules that depend on them unusable from React Native. Fortunately, there’s a solution to this problem, but it takes some work.SolutionIf you’re familiar the module bundler Browserify, (...)

“Scalability in Node.js is not an afterthought. It’s something that’s baked into the core of the runtime. Node is named Node to emphasize the idea that a Node application should comprise multiple small distributed nodes that communicate with each other.”

#IOJS, and #NodeJs foundation —

La fin prochaine du « spork » ?

Joyent, Inc., the container infrastructure software company and corporate steward of the Node.js open source project, today announced that it will move to establish a formal open governance model for Node.js with the creation of an independent foundation. Joyent will join forces with IBM, PayPal, Microsoft Corp, Fidelity and The Linux Foundation to establish the Node.js Foundation, which will be committed to the continued growth and evolution of Node.js, while maintaining a collaborative environment to benefit all users.
