eslint-config-guard

Set of configuration files (shareable configs) for ESLint to guard/protect from problems in different areas of JavaScript development.

Includes:

• guard - contains rules for possible errors, best practices, strict mode and variables; extends eslint:recommended;
• guard/editor - rules corresponding to editor preferences (like editorconfig) such as eol-last, linebreak-style, no-trailing-spaces;
• guard/esnext - configuration for ECMAScript 6/2015+ features;
• guard/indent - configuration of indent rule;
• guard/jsdoc - contains rules related to JSDoc;
• guard/no-prettier - adds "prettier/prettier": "off" to rules; can be helpful to use with TSDX;
• guard/node - configuration related to Node.js and CommonJS;
• guard/proper-arrows - configuration for stylistic rules related to arrow functions (see @getify/eslint-plugin-proper-arrows);
• guard/react - configuration for React and JSX; extends plugin:react/recommended;
• guard/style - rules for stylistic issues;
• guard/test - appropriate for use in tests (relaxes some rules from other configs);
• guard/test-jest - appropriate for use in Jest tests; extends guard/test;
• guard/test-mocha - appropriate for use in Mocha tests; extends guard/test;

The following files are combined configs which extend other configs:

• guard/ext-style - extends guard/indent and guard/style;
• guard/optimum - extends guard and guard/ext-style;
• guard/optimum-next - extends guard/optimum and guard/esnext.

See eslint-config-ts-guard for configuration files related to TypeScript.
