This module saves time in three ways for you:

No configuration - The easier way to enforce code quality in your project. No configuration rules. It just works.
Automatically format code - Just run yarn lint-fix and say goodbye to messy or inconsistent code.
Catch style issues & programmer errors early - Reduce manual review in the code review process, and leave simple things to tools to save time.

No hesitation. No more maintenance .eslintrc. Give it a try right now!

Install

Usage

Shareable configs are designed to work with the extends feature of .eslintrc files. You can learn more about Shareable Configs on the official ESLint website.

1、Then, add this to your .eslintrc file:

{
  "extends": "dt-insight"
}

Note: We omitted the eslint-config- prefix since it is automatically assumed by ESLint.

You can not override settings. Because this is a Code Style Guide for dt-insight's project.

2、Add script to package.json:

"scripts": {
  "lint": "npx eslint './src/**/*.ts' './src/**/*.tsx'",
  "lint-fix": "npx eslint './src/**/*.ts' './src/**/*.tsx' --fix"
},

You can use yarn lint-fix to correct most code style problems.

How do I disable a rule?

In rare cases, you'll need to break a rule and hide the error generated by Code Style Guide.

eslint-config-dt-insight uses ESLint under-the-hood and you can hide errors as you normally would if you used ESLint directly.

Disable all rules on a specific line:

file = 'I know what I am doing' // eslint-disable-line

Or, disable only the "no-use-before-define" rule:

file = 'I know what I am doing' // eslint-disable-line no-use-before-define

Or, disable the "no-use-before-define" rule for multiple lines:

/* eslint-disable no-use-before-define */
console.log('offending code goes here...')
console.log('offending code goes here...')
console.log('offending code goes here...')
/* eslint-enable no-use-before-define */

Looking for something easier than this?

You can add to your yarn lint script and install eslint plugin for vscode.
