First, make sure you've installed the plugin as a dev dependency:

npm install eslint-plugin-rxjs-angular --save-dev
# Or using yarn
yarn add eslint-plugin-rxjs-angular --dev

Next, update your existing .eslintrc.json file by modifying the TypeScript override block (the one targeting *.ts files) to include the plugin, required parser options, and the desired rule. Here's the modified version with all necessary changes:

{
  "root": true,
  "ignorePatterns": [
    "projects/**/*"
  ],
  "overrides": [
    {
      "files": [
        "*.ts"
      ],
      "parserOptions": {
        "project": [
          "tsconfig.json",
          "e2e/tsconfig.json"
        ],
        "createDefaultProgram": true,
        "ecmaVersion": 2019,
        "sourceType": "module"
      },
      "plugins": ["rxjs-angular"],
      "extends": [
        "plugin:@angular-eslint/recommended",
        "plugin:@angular-eslint/template/process-inline-templates"
        // Uncomment below if you want to use all recommended rules from the plugin
        // "plugin:rxjs-angular/recommended"
      ],
      "rules": {
        "@angular-eslint/component-selector": [
          "error",
          {
            "prefix": "app",
            "style": "kebab-case",
            "type": "element"
          }
        ],
        "@angular-eslint/directive-selector": [
          "error",
          {
            "prefix": "app",
            "style": "camelCase",
            "type": "attribute"
          }
        ],
        "rxjs-angular/prefer-async-pipe": "error"
      }
    },
    {
      "files": [
        "*.html"
      ],
      "extends": [
        "plugin:@angular-eslint/template/recommended"
      ],
      "rules": {}
    }
  ]
}

Key Changes Explained: #

• Added plugins array: Included "rxjs-angular" to enable the plugin's rule set.
• Updated parserOptions: Added ecmaVersion: 2019 and sourceType: "module" to meet the plugin's requirements (your existing project config already covers the project setting).
• Added the target rule: Added "rxjs-angular/prefer-async-pipe": "error" to enforce the async pipe usage as specified in the plugin example.
• Optional recommended rules: If you want to enable all the plugin's pre-configured best practices instead of just one rule, uncomment the "plugin:rxjs-angular/recommended" line in the extends array.

After making these changes, run ESLint to verify everything works as expected:

ng lint
