For the local installation of the project directory:

$npm i eslint-g

1. After installation, you can use ESLint through the eslint command in the terminal.

Configuration

2. The easiest way to configure is to set up a .eslintrc JSON file that describes all linting rules.

An example of .eslintrc:

{"env": {"node": true, "browser": true}, "globals": {"exampleGlobalVariable": true}, "rules": {"no-console": 0, "space-infix-ops": "error", "quotes": ["error", "single", {"avoidEscape": true, "allowTemplateLiterals": true}] "space-before-blocks": ["error", "always"], "semi": ["error", "never"]}, "plugins": []}

Main fields:

Parse-specifies the parser

ParserOptions-specify parser options

Env-specifies the environment in which the script runs

Root-when true, stop looking up the configuration file in the parent directory

Globals-additional global variables accessed by the script during execution

Rules-add your custom rules here
