Golang Tutorial for Node.js Developers, Part I.: Getting started

At RisingStack we’ve been building webapps for our clients with Node.js for ~5 years — therefore we’ve seen the rise of Node from a relatively unknown, edgy technology to the mainstream status it enjoys Today.

If you take a look at the history of Node.js, you can see that it is now widely used in enterprise environments as well. However, we couldn’t miss the fact, that in the past years Go emerged as the interesting and hyped new back-end language. Go is becoming the new enterprise language besides Java and C# and for a good reason.

Throughout this tutorial series, we’ll cover the basics of getting started with the Go language, while building an app and exposing it through a REST, GraphQL and GRPC API together.

Design Patterns in Node.js: a Practical Guide

Design patterns, simply put, are a way for you to structure your solution’s code in a way that allows you to gain some kind of benefit. Such as faster development speed, code reusability, and so on.

In this article, we will look at how to identify these patterns out in the wild and look at how you can start using them in your own projects.

Postman now supports GraphQL!

Postman joins the group of companies acknowledging the GraphQL qualities and has recently announced the support for GraphQL in their service. The latest release of Postman v7.2 enables:

  • sending GraphQL queries in the request body,
  • GraphQL variables,
  • GraphQL query autocompletion.

This is a great complement to the previous update which introduced schema support, all that combined makes it possible to create & store GraphQL schemas directly in Postman itself!
