Shareable configurations

Recommended

This plugin exports a recommended configuration that enforces Canonical type good practices.

To enable this configuration use the extends property in your .eslintrc config file:

{
  "extends": [
    "plugin:canonical/recommended"
  ],
  "plugins": [
    "canonical"
  ]
}

See ESLint documentation for more information about extending configuration files.

Rules

id-match

The --fix option on the command line automatically fixes problems reported by this rule.

Note: This rule is equivalent to id-match, except for addition of ignoreNamedImports.

This rule requires identifiers in assignments and function definitions to match a specified regular expression.

Options

• "properties": false (default) does not check object properties
• "properties": true requires object literal properties and member expression assignment properties to match the specified regular expression
• "classFields": false (default) does not class field names
• "classFields": true requires class field names to match the specified regular expression
• "onlyDeclarations": false (default) requires all variable names to match the specified regular expression
• "onlyDeclarations": true requires only var, function, and class declarations to match the specified regular expression
• "ignoreDestructuring": false (default) enforces id-match for destructured identifiers
• "ignoreDestructuring": true does not check destructured identifiers
• "ignoreNamedImports": false (default) enforces id-match for named imports
• "ignoreNamedImports": true does not check named imports

no-restricted-strings

Disallow specified strings.

The following patterns are considered problems:

// Options: [["bar"]]
var foo = "bar"
// Message: Disallowed string: 'bar'.

// Options: [["bar"]]
const foo = `bar ${baz}`;
// Message: Disallowed string in template: 'bar'.

The following patterns are not considered problems:

const foo = "bar";

Options

The 1st option is an array of strings that cannot be contained in the codebase.

sort-keys

The --fix option on the command line automatically fixes problems reported by this rule.

Note: This rule is equivalent to sort-keys, except that it is fixable.

This rule requires identifiers in assignments and function definitions to match a specified regular expression.

Options

The 1st option is "asc" or "desc".

• "asc" (default) - enforce properties to be in ascending order.
• "desc" - enforce properties to be in descending order.

The 2nd option is an object which has 3 properties.

• caseSensitive - if true, enforce properties to be in case-sensitive order. Default is true.
• minKeys - Specifies the minimum number of keys that an object should have in order for the object's unsorted keys to produce an error. Default is 2, which means by default all objects with unsorted keys will result in lint errors.
• natural - if true, enforce properties to be in natural order. Default is false. Natural Order compares strings containing combination of letters and numbers in the way a human being would sort. It basically sorts numerically, instead of sorting alphabetically. So the number 10 comes after the number 3 in Natural Sorting.
