Rule: quotemark

Enforces quote character for string literals.

Notes

• Has Fix

Config

Five arguments may be optionally provided:

• "single" enforces single quotes.
• "double" enforces double quotes.
• "backtick" enforces backticks.
• "jsx-single" enforces single quotes for JSX attributes.
• "jsx-double" enforces double quotes for JSX attributes.
• "avoid-template" forbids single-line untagged template strings that do not contain string interpolations. Note that backticks may still be used if "avoid-escape" is enabled and both single and double quotes are present in the string (the latter option takes precedence).
• "avoid-escape" allows you to use the "other" quotemark in cases where escaping would normally be required. For example, [true, "double", "avoid-escape"] would not report a failure on the string literal 'Hello "World"'.

Examples

"quotemark": true,single,avoid-escape,avoid-template

"quotemark": true,single,jsx-double

Schema

{
  "type": "array",
  "items": {
    "type": "string",

    ]
  },
  "minLength": 0,
  "maxLength": 5

Rule: indent

Enforces indentation with tabs or spaces.

Rationale

Using only one of tabs or spaces for indentation leads to more consistent editor behavior, cleaner diffs in version control, and easier programmatic manipulation.

Notes

• Has Fix

Config

One of the following arguments must be provided:

• spaces enforces consistent spaces.
• tabs enforces consistent tabs.

A second optional argument specifies indentation size:

• 2 enforces 2 space indentation.
• 4 enforces 4 space indentation.

Indentation size is required for auto-fixing, but not for rule checking.

NOTE: auto-fixing will only convert invalid indent whitespace to the desired type, it will not fix invalid whitespace sizes.

Examples

"indent": true,spaces

"indent": true,spaces,4

"indent": true,tabs,2

Schema

{
  "type": "array",
  "items": [
    {
      "type": "string",

Rule: no-empty

Disallows empty blocks.

Blocks with a comment inside are not considered empty.

Rationale

Empty blocks are often indicators of missing code.

Config

If allow-empty-catch is specified, then catch blocks are allowed to be empty. If allow-empty-functions is specified, then function definitions are allowed to be empty.

Examples

"no-empty": true

"no-empty": true,allow-empty-catch

"no-empty": true,allow-empty-functions

"no-empty": true,allow-empty-catch,allow-empty-functions

Notes

• Has Fix

Config

Several arguments may be optionally provided:

• "check-branch" checks branching statements (if/else/for/while) are followed by whitespace.
• "check-decl"checks that variable declarations have whitespace around the equals token.
• "check-operator" checks for whitespace around operator tokens.
• "check-module" checks for whitespace in import & export statements.
• "check-separator" checks for whitespace after separator tokens (,/;).
• "check-rest-spread" checks that there is no whitespace after rest/spread operator (...).
• "check-type" checks for whitespace before a variable type specification.
• "check-typecast" checks for whitespace between a typecast and its target.

Rule: unnecessary-bind

Prevents unnecessary and/or misleading scope bindings on functions.

Rationale

function expressions that are immediately bound to this are equivalent to () => arrow lambdas. Additionally, there's no use in binding a scope to an arrow lambda, as it already has one.

Notes

• Requires Type Info

• Has Fix

Config

One of the following arguments must be provided:

• spaces enforces consistent spaces.
• tabs enforces consistent tabs.

A second optional argument specifies indentation size:

• 2 enforces 2 space indentation.
• 4 enforces 4 space indentation.

Indentation size is required for auto-fixing, but not for rule checking.

NOTE: auto-fixing will only convert invalid indent whitespace to the desired type, it will not fix invalid whitespace sizes.

Examples

"indent": true,spaces

"indent": true,spaces,4

"indent": true,tabs,2

Schema

{
  "type": "array",
  "items": [
    {
      "type": "string",
      "enum": [
        "tabs",
        "spaces"
      ]
    },
    {
      "type": "number",
      "enum": [
        2,
        4
      ]
    }
  ],
  "minLength": 0,
  "maxLength": 5
}

Rule: indent

Enforces indentation with tabs or spaces.

Rationale

Using only one of tabs or spaces for indentation leads to more consistent editor behavior, cleaner diffs in version control, and easier programmatic manipulation.
