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.

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 article, we take a look at Codemods, a tool for making sweeping changes across your code with ease and effectiveness. Codemods are invented by a team of developers from Facebook to assist large-scale migrations in code-base, and we are going to take a deep look into a particular codemod tool called jscodeshift. Refactoring Before we dive into the codemod tools like jscodeshift, we need to understand why we need to do large-scale refactorings and what is really meant by refactoring.
