Duplicated Code

Duplicated code can lead to software that is hard to understand and difficult to change. The Don't Repeat Yourself (DRY) principle states:

Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.

When you violate DRY, bugs and maintenance problems are sure to follow. Duplicated code has a tendency to both continue to replicate and also to diverge (leaving bugs as two similar implementations differ in subtle ways).

Tuning

This issue has a mass of 147.

We set useful threshold defaults for the languages we support but you may want to adjust these settings based on your project guidelines.

The threshold configuration represents the minimum mass a code block must have to be analyzed for duplication. The lower the threshold, the more fine-grained the comparison.

If the engine is too easily reporting duplication, try raising the threshold. If you suspect that the engine isn't catching enough duplication, try lowering the threshold. The best setting tends to differ from language to language.

See codeclimate-duplication's documentation for more information about tuning the mass threshold in your .codeclimate.yml.

} from "@angular/core";

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",
    "enum": [
      "single",
      "double",
      "backtick",
      "jsx-single",
      "jsx-double",
      "avoid-escape",
      "avoid-template"
    ]

The selector should be kebab-cased and include a dash (https://angular.io/guide/styleguide#style-05-02)

    selector: 'pcheckbox',

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

{
  "items": [
    {
      "enum": [
        "attribute",
