Rule: no-inferrable-types

Disallows explicit type declarations for variables or parameters initialized to a number, string, or boolean.

Rationale

Explicit types where they can be easily inferred by the compiler make code more verbose.

Notes

• TypeScript Only
• Has Fix

Config

Two arguments may be optionally provided:

• ignore-params allows specifying an inferrable type annotation for function params. This can be useful when combining with the typedef rule.
• ignore-properties allows specifying an inferrable type annotation for class properties.

Examples

"no-inferrable-types": true

"no-inferrable-types": true,ignore-params

"no-inferrable-types": true,ignore-params,ignore-properties

Schema

{
  "type": "array",
  "items": {
    "type": "string",
    "enum": [
      "ignore-params",
      "ignore-properties"
    ]
  },
  "minLength": 0,
  "maxLength": 2
}

Rule: component-selector

Component selectors should follow given naming rules.

See more at https://angular.io/guide/styleguide#style-02-07, https://angular.io/guide/styleguide#style-05-02 and https://angular.io/guide/styleguide#style-05-03.

Rationale

• Consistent conventions make it easy to quickly identify and reference assets of different types.
• Makes it easier to promote and share the component in other apps.
• Components are easy to identify in the DOM.
• Keeps the element names consistent with the specification for Custom Elements.
• Components have templates containing HTML and optional Angular template syntax.
• They display content. Developers place components on the page as they would native HTML elements and WebComponents.
• It is easier to recognize that a symbol is a component by looking at the template's HTML.

Notes

• TypeScript Only

Config

Options accept three obligatory items as an array: 1. element or attribute forces components to be used as either elements, attributes, or both (not recommended) 2. A single prefix (string) or array of prefixes (strings) which have to be used in component selectors. 3. kebab-case or camelCase allows you to pick a case.

Examples

"component-selector": true,element,my-prefix,kebab-case

"component-selector": true,element,ng,ngx,kebab-case

"component-selector": true,attribute,myPrefix,camelCase

"component-selector": true,element,attribute,myPrefix,camelCase

Schema

{
  "items": [
    {
      "enum": [
        "attribute",
        "element"
      ]
    },
    {
      "oneOf": [
        {
          "items": {
            "type": "string"
          },
          "type": "array"
        },
        {
          "type": "string"
        }
      ]
    },
    {
      "enum": [
        "camelCase",
        "kebab-case"
      ]
    }
  ],
  "maxLength": 3,
  "minLength": 3,
  "type": "array"
}
