eslint-config-valorsoft

Welcome to the most strict eslint config ever

Philosophy

• contains all rules
• almost all rules enabled
• this config is highly opinionated

Where to use

• anywhere
• for tests better to add env:"node" and disable newline-per-chained-call rule

How to use

• install latest npm

  $(sudo) npm install -g npm@latest
  

• add task eslint to package.json script section

  "eslint": "./node_modules/.bin/eslint --ignore-path .gitignore  --ext js --fix . .config",
  

• add linting to tests step scripts package.json section

  "test": "npm run eslint && ..."
  

• create .eslintrc.json near to you package.json with the following content

  {
    "extends": "./node_modules/eslint-config-valorsoft/.eslintrc.json",
    "env": {
      "node": true
    }
  }
  

• run npm t to check that all is working correctly

What is disabled

• no-eq-null - duplicates eqeqeq:smart
• no-restricted-imports, no-restricted-modules, no-restricted-globals - dependant on project requirements
• id-match - not found any particular use of this rule, camelCase is enough
• jsx-quotes - I don't use jsx so I don't care
• no-plusplus - why not ++? It's nice to use when you know what you are doing
• no-restricted-syntax - duplicates no-with and disabled functional expressions
• no-ternary - why not? but not nested ternary please
• require-jsdoc- nice thing, but hard to follow
• spaced-comment - nice for meaningful comments, bad for quick code commenting
• wrap-regex - no need
• prefer-reflect - compatibility is to low to use
• newline-before-return - TBD

What is tweaked

• indent - 2 spaces rulezzz!
• max-len - extended to 120 chars
• newline-per-chained-call - extended ignoreChainWithDepth to 3
• eqeqeq - smart mode enabled
• dot-location - property mode enabled
• no-implicit-coercion - boolean implicit coercion enabled
• func-style - declaration only please
• no-use-before-define - usage of function before declarations are allowed
• no-mixed-requires- grouping and allowCall checks enabled
• linebreak-style - unix only
• one-var - never use one var|let|const per block
• padded-blocks - never add useless padding
• quote-props - quote properties only as-needed and keywords
• no-magic-numbers - ignore -1,0,1 as most often used numbers and ignoreArrayIndexes, enforceConst are enabled

Contribution

• what I really appreciate is configs for IDEs
• to change any rule you should have strong arguments and not only opinion
