Tadashi Shigeoka · Sat, December 28, 2019
I’ll introduce the steps for installing and initially setting up ESLint in an Express (Node.js) project.
Background for ESLint Introduction
I’m introducing ESLint for purposes like “improving code quality” and “organizing code style.”
- Official site: ESLint - Pluggable JavaScript linter
I’ll explain the complete flow from ESLint installation to initial setup for an Express (Node.js) project based on the following GitHub Pull Request:
ESLint Installation
npm install eslint --save-dev
npm install eslint —save-dev · Pull Request #9 · codenote-net/expressjs-sandbox
ESLint Initial Setup
$(npm bin)/eslint --init
? How would you like to use ESLint? To check syntax, find problems, and enforce code style
? What type of modules does your project use? CommonJS (require/exports)
? Which framework does your project use? None of these
? Does your project use TypeScript? No
? Where does your code run? Node
? How would you like to define a style for your project? Use a popular style guide
? Which style guide do you want to follow? Standard: https://github.com/standard/standard

$(npm bin)/eslint —init · Pull Request #9 · codenote-net/expressjs-sandbox
Add eslint --fix to npm-scripts
Add “lint”: “eslint .” to npm scripts · Pull Request #9 · codenote-net/expressjs-sandbox
npm run lint:fix
That’s all from the Gemba.
