Rule: prefer-const

Requires that variable declarations use const instead of let and var if possible.

If a variable is only assigned to once when it is declared, it should be declared using 'const'

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"'.

Rule: jsdoc-format

Enforces basic format rules for JSDoc comments.

The following rules are enforced for JSDoc comments (comments starting with /**):

• each line contains an asterisk and asterisks must be aligned
• each asterisk must be followed by either a space or a newline (except for the first and the last)
• the only characters before the asterisk on each line must be whitespace characters
• one line comments must start with /** and end with */
• multiline comments don't allow text after /** in the first line (with option "check-multiline-start")

Rationale

Helps maintain a consistent, readable style for JSDoc comments.

Config

You can optionally specify the option "check-multiline-start" to enforce the first line of a multiline JSDoc comment to be empty.

Examples

"jsdoc-format": true

"jsdoc-format": true,check-multiline-start

Rule: ordered-imports

Requires that import statements be alphabetized and grouped.

Enforce a consistent ordering for ES6 imports: - Named imports must be alphabetized (i.e. "import {A, B, C} from "foo";") - The exact ordering can be controlled by the named-imports-order option. - "longName as name" imports are ordered by "longName". - Import sources must be alphabetized within groups, i.e.: import * as foo from "a"; import * as bar from "b"; - Groups of imports are delineated by blank lines. You can use this rule to group imports however you like, e.g. by first- vs. third-party or thematically or you can define groups based upon patterns in import path names.

Notes

• Has Fix

Config

You may set the "import-sources-order" option to control the ordering of source imports (the "foo" in import {A, B, C} from "foo").

Possible values for "import-sources-order" are:

• "case-insensitive': Correct order is "Bar", "baz", "Foo". (This is the default.)
• "case-insensitive-legacy': Correct order is "Bar", "baz", "Foo".
• "lowercase-first": Correct order is "baz", "Bar", "Foo".
• "lowercase-last": Correct order is "Bar", "Foo", "baz".
• "any": Allow any order.

You may set the "grouped-imports" option to control the grouping of source imports (the "foo" in import {A, B, C} from "foo"). The grouping used is controlled by the "groups" option.

Possible values for "grouped-imports" are:

• false: Do not enforce grouping. (This is the default.)
• true: Group source imports using default grouping or groups setting.

The value of "groups" is a list of group rules of the form:

[{
    "name": "optional rule name",
    "match": "regex string",
    "order": 10
}, {
    "name": "pkga imports",
    "match": "^@pkga",
    "order": 20
}]

there is also a simplified form where you only pass a list of patterns and the order is given by the position in the list

["^@pkga", "^\.\."]

The first rule in the list to match a given import is the group that is used. If no rule in matched then the import will be put in an unmatched group at the end of all groups. The groups must be ordered based upon the sequential value of the order value. (ie. order 0 is first)

If no "groups" options is set, a default grouping is used of third-party, parent directories and the current directory. ("bar", "../baz", "./foo".)

You may set the "named-imports-order" option to control the ordering of named imports (the {A, B, C} in import {A, B, C} from "foo").

Possible values for "named-imports-order" are:

• "case-insensitive': Correct order is {A, b, C}. (This is the default.)
• "case-insensitive-legacy': Correct order is "Bar", "baz", "Foo".
• "lowercase-first": Correct order is {b, A, C}.
• "lowercase-last": Correct order is {A, C, b}.
• "any": Allow any order.

You may set the "module-source-path" option to control the ordering of imports based full path or just the module name

Possible values for "module-source-path" are:

• "full': Correct order is "./a/Foo", "./b/baz", "./c/Bar". (This is the default.)
• "basename": Correct order is "./c/Bar", "./b/baz", "./a/Foo".

Rule: no-var-keyword

Disallows usage of the var keyword.

Use let or const instead.

Rationale

Declaring variables using var has several edge case behaviors that make var unsuitable for modern code. Variables declared by var have their parent function block as their scope, ignoring other control flow statements. vars have declaration "hoisting" (similar to functions) and can appear to be used before declaration.

Variables declared by const and let instead have as their scope the block in which they are defined, and are not allowed to used before declaration or be re-declared with another const or let.

Rule: semicolon

Enforces consistent semicolon usage at the end of every statement.

Notes

• Has Fix

Config

One of the following arguments must be provided:

• "always" enforces semicolons at the end of every statement.
• "never" disallows semicolons at the end of every statement except for when they are necessary.

The following arguments may be optionally provided:

• "ignore-interfaces" skips checking semicolons at the end of interface members.
• "ignore-bound-class-methods" skips checking semicolons at the end of bound class methods.
• "strict-bound-class-methods" disables any special handling of bound class methods and treats them as any other assignment. This option overrides "ignore-bound-class-methods".

Examples

"semicolon": true,always

"semicolon": true,never

"semicolon": true,always,ignore-interfaces

"semicolon": true,always,ignore-bound-class-methods

Rule: ordered-imports

Requires that import statements be alphabetized and grouped.

Enforce a consistent ordering for ES6 imports: - Named imports must be alphabetized (i.e. "import {A, B, C} from "foo";") - The exact ordering can be controlled by the named-imports-order option. - "longName as name" imports are ordered by "longName". - Import sources must be alphabetized within groups, i.e.: import * as foo from "a"; import * as bar from "b"; - Groups of imports are delineated by blank lines. You can use this rule to group imports however you like, e.g. by first- vs. third-party or thematically or you can define groups based upon patterns in import path names.

Notes

• Has Fix

Config

You may set the "import-sources-order" option to control the ordering of source imports (the "foo" in import {A, B, C} from "foo").

Possible values for "import-sources-order" are:

• "case-insensitive': Correct order is "Bar", "baz", "Foo". (This is the default.)
• "case-insensitive-legacy': Correct order is "Bar", "baz", "Foo".
• "lowercase-first": Correct order is "baz", "Bar", "Foo".
• "lowercase-last": Correct order is "Bar", "Foo", "baz".
• "any": Allow any order.

You may set the "grouped-imports" option to control the grouping of source imports (the "foo" in import {A, B, C} from "foo"). The grouping used is controlled by the "groups" option.

Possible values for "grouped-imports" are:

• false: Do not enforce grouping. (This is the default.)
• true: Group source imports using default grouping or groups setting.

The value of "groups" is a list of group rules of the form:

[{
    "name": "optional rule name",
    "match": "regex string",
    "order": 10
}, {
    "name": "pkga imports",
    "match": "^@pkga",
    "order": 20
}]

there is also a simplified form where you only pass a list of patterns and the order is given by the position in the list

["^@pkga", "^\.\."]

The first rule in the list to match a given import is the group that is used. If no rule in matched then the import will be put in an unmatched group at the end of all groups. The groups must be ordered based upon the sequential value of the order value. (ie. order 0 is first)

If no "groups" options is set, a default grouping is used of third-party, parent directories and the current directory. ("bar", "../baz", "./foo".)

You may set the "named-imports-order" option to control the ordering of named imports (the {A, B, C} in import {A, B, C} from "foo").

Possible values for "named-imports-order" are:

• "case-insensitive': Correct order is {A, b, C}. (This is the default.)
• "case-insensitive-legacy': Correct order is "Bar", "baz", "Foo".
• "lowercase-first": Correct order is {b, A, C}.
• "lowercase-last": Correct order is {A, C, b}.
• "any": Allow any order.

You may set the "module-source-path" option to control the ordering of imports based full path or just the module name

Possible values for "module-source-path" are:

• "full': Correct order is "./a/Foo", "./b/baz", "./c/Bar". (This is the default.)
• "basename": Correct order is "./c/Bar", "./b/baz", "./a/Foo".

Rule: prefer-const

Requires that variable declarations use const instead of let and var if possible.

If a variable is only assigned to once when it is declared, it should be declared using 'const'

Notes

• Has Fix

Config

An optional object containing the property "destructuring" with two possible values:

• "any" (default) - If any variable in destructuring can be const, this rule warns for those variables.
• "all" - Only warns if all variables in destructuring can be const.

"prefer-const": true,[object Object]

Rule: no-var-keyword

Disallows usage of the var keyword.

Use let or const instead.

Rationale

Declaring variables using var has several edge case behaviors that make var unsuitable for modern code. Variables declared by var have their parent function block as their scope, ignoring other control flow statements. vars have declaration "hoisting" (similar to functions) and can appear to be used before declaration.

Variables declared by const and let instead have as their scope the block in which they are defined, and are not allowed to used before declaration or be re-declared with another const or let.

Notes

• Has Fix

Config

Not configurable.
