ESLint: The Next-Generation JavaScript Linter
|
|
It was the summer of 2013 and I was working on a project for my employer, Box. I had just finished wiring up JSDoc as a nightly build using a plugin to detect T3 patterns in our code and document them automatically. It occurred to me that these patterns might be easy to get wrong, and I started looking for a way to automatically detect incorrect patterns. I immediately turned to JSHint because we were already using it and I thought it could support plugins. Unfortunately, it could not.
Still, I couldn’t get the idea of a linter with pluggable runtime rules out of my head. I had just spent a bunch of time learning about Esprima and abstract syntax trees (ASTs), and I thought to myself, “It can’t be all that hard to create a pluggable JavaScript linter using an AST.” It was from those initial thoughts that ESLint was born.
