eslint-plugin-no-this-in-jsx-component-name v0.0.1

eslint-plugin-no-this-in-jsx-component-name

This ESLint rule checks JSX tags for <this.ComponentName /> since user-defined components must be capitalized.

More here: https://facebook.github.io/react/docs/jsx-in-depth.html#user-defined-components-must-be-capitalized

Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-no-this-in-jsx-component-name:

$ npm install eslint-plugin-no-this-in-jsx-component-name --save-dev

Note: If you installed ESLint globally, you must also install eslint-plugin-no-this-in-jsx-component-name globally.

Usage

Add no-this-in-jsx-component-name to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "no-this-in-jsx-component-name"
    ]
}

Then add no-this-in-jsx-component-name's only rule under the rules section.

{
    "rules": {
        "no-this-in-jsx-component-name/no-this-in-jsx-component-name": "error"
    }
}

Rule Details

This rule aims to avoid compilation errors in React when a component's name starts with "this".

The following patterns are considered warnings:

<this.ComponentName />
<this.ComponentName>Content</this.ComponentName>

The following patterns are not warnings:

<div />
<MyComponent />

As alternatives, use either of these options:

const Component = this.Component;
const { ComponentA, ComponentB } = this;
