In this tutorial, we will see how to setup automated code coverage metrics collection for your Ember addons using Coveralls and Github Actions. Why Code coverage? In simple terms, code coverage is the fraction or percentage of code paths executed by some test or test suite of a program. It is generally measured by a tool which executes the test and logs the lines of code, the test “touches” while running.

Snowpack is a post-install tool. It runs after npm install, and it essentially exists to convert your npm packages (in your “nodemodules/” directory) into JS files that run in the browser without a bundler (written to a “webmodules/” directory). Creating a sample app In this tutorial we are going to create a simple demo app which is going to make use of a library called finance. We are going to create an app to calculate simple interest from principal, rate and time.

In this article, we are going to take a look at a tool called JARVIS which will profoundly transform the way how you write codemods. This is a continuation post for AST Finder which is a tool to generate an api to find AST nodes automatically from source code. If you want to know more about codemods, their building blocks and how they work, please check out this detailed post about codemods.

In this article, we are going to take a look at a tool called ‘AST Finder’ which will significantly improve the developer experience for writing codemods. This is a continuation post for AST Builder which is a tool to generate AST nodes automatically from source code. If you want to know more about codemods, their building blocks and how they work, please check out this detailed post about codemods. What? AST Finder is actually a playground for finding AST nodes using source code.

In this article, we are going to take a look at a tool called ‘AST Builder’ which will significantly improve the developer experience for writing codemods. Codemod is a tool/library to assist you with large-scale codebase refactors that can be partially automated but still require human oversight and occasional intervention. Codemod was developed at Facebook and released as open source. If you want to know more about codemods, their building blocks and how they work, please check out this detailed post about codemods.

In this article, we are going to take a glimpse at the ember-codemods-telemetry-helpers package and how it helps to create more advanced codemods for Ember.js. If you want a more in-depth introduction to codemods, you can checkout this post detailing the why’s and how’s of codemods. Telemetry for layman First we will take a look at what Telemetry is all about. According to Wikipedia, Telemetry is the collection of measurements or other data at remote or inaccessible points and their automatic transmission to receiving equipment for monitoring.

In this post, we are going to share you a mind map of the book called The Craftsman by Richard Sennett. Richard Sennett is a prime observer of society … one of his great strengths, the thing that makes his narrative so gripping, is the sheer range of his thinking and his brilliance in relating the past to the present. The Craftsman is a complex but very rewarding read about craftsmanship, pride in one’s work and the differences between individual work and mechanical production, and the intellectual investment in the former versus the more mechanistic approach in the latter.

This post is the second in the series of posts called PlantUML in Spacemacs. In this post we are going to see how we can create awesome Mind maps in Spacemacs using PlantUML. Mind map diagrams is the new feature recently rolled out in PlantUML and they are still in the beta* stage. And you will find only minimal documentation in the official site related to mind map diagrams. This post gives you some additional bonus information such as adding colors to your mind map, creating high resolution mind maps and so on.

This article is the first in the series of articles about including and using PlantUML in Spacemacs to do some amazing things. In this article we will see how to setup PlantUML in Spacemacs and use it. In the upcoming posts we will see some advanced usage of PlantUML and some awesome stuff you can do with it. Spacemacs Spacemacs is a community-driven Emacs distribution. It is a new way to experience Emacs with a sophisticated and polished set-up focused on ergonomics, mnemonics and consistency.

Coming from a vim world with tmux, I had really missed the multiple split window layout in Spacemacs. But after knowing how to define custom layouts this seemed to be an easy exercise for me. So I thought, I should write a blog post about it to help others setup awesome layouts and workspaces with Spacemacs. Some Terminology Here I want to make some clarifications on the terminology surrounding vim, tmux and Emacs on windows, layouts, panes and buffers.
