- Language Server Protocol Tutorial: From VSCode to Vim (Publication)The main artifact of all your work is most likely plain text files. So why don't you use Notepad to create them? Find out how the Language Server Protocol can transform text editors into code editors, without coupling.
- Write Code to Rewrite Your Code: jscodeshift (Publication)How many times have you used the find-and-replace functionality (or RegEx) across a directory to make changes to JavaScript source files? Up your refactoring game by using codemods, scripts used to rewrite other scripts. In this article, Toptal Freelance Developer Jeremy Greer walks us through three common uses of codemods, using the toolkit “jscodeshift.”
