eslint-plugin-better-dates

An ESlint plugin to prevent Date-related bugs.

Installation

Make sure you have TypeScript and @typescript-eslint/parser installed:

$ yarn add -D typescript @typescript-eslint/parser
$ npm i --save-dev typescript @typescript-eslint/parser

Then install the plugin:

$ yarn add -D eslint-plugin-better-dates
$ npm i --save-dev eslint-plugin-better-dates

Usage

Add @typescript-eslint/parser to the parser field, your tsconfig.json relative path to parserOptions.project, and better-dates to the plugins section of your .eslintrc configuration file, then configure the rules you want to use under the rules section.

{
  "parser": "@typescript-eslint/parser",
  "parserOptions": { "project": "./tsconfig.json" },
  "plugins": ["better-dates"],
  "rules": {
    "better-dates/ban-date-mutation": "error"
  }
}

Note: Make sure to use eslint --ext .js,.ts since by default eslint will only search for .js files.
