eslint-plugin-no-interpolation-spacing v1.0.4

eslint-plugin-no-interpolation-spacing

A custom ESLint plugin to enforce no spacing between Angular-style interpolations ({{ }}) and HTML elements, ensuring clean and consistent coding standards for your Angular templates.

Installation

Install the plugin using npm:

npm install eslint-plugin-no-interpolation-spacing --save-dev

Or using yarn:

yarn add eslint-plugin-no-interpolation-spacing --dev

Usage

Add the Plugin to Your ESLint Configuration

Add no-interpolation-spacing to your ESLint configuration file. Below is an example using .eslintrc.json:

{
    "plugins": ["no-interpolation-spacing"],
    "rules": {
        "no-interpolation-spacing/no-space-between-interpolation-and-element": "error"
    }
}

Or if you use eslint.config.js:

const noInterpolationSpacingPlugin = require('eslint-plugin-no-interpolation-spacing');

module.exports = {
  plugins: {
    'no-interpolation-spacing': noInterpolationSpacingPlugin,
  },
  rules: {
    'no-interpolation-spacing/no-space-between-interpolation-and-element': 'error',
  },
};

Configuration

This plugin is primarily designed for Angular templates and HTML files. Make sure your ESLint configuration targets .html files.

Example in eslint.config.js:

module.exports = [
  {
    files: ['**/*.html'], // Apply only to HTML files
    plugins: {
      'no-interpolation-spacing': require('eslint-plugin-no-interpolation-spacing'),
    },
    rules: {
      'no-interpolation-spacing/no-space-between-interpolation-and-element': 'error',
    },
  },
];

Rule no-space-between-interpolation-and-element

This rule ensures there are no spaces or newlines between Angular-style interpolations ({{ }}) and adjacent elements in HTML files.

Example:

✅ Correct:

<div>{{value}}</div>
<span>Hello {{name}}</span>

❌ Incorrect:

<div> {{value}}</div>
<span>Hello {{ name }}</span>
