eslint-plugin-no-new-instance

ESLint rule for disallowing new instances of configured classes

Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-no-new-instance:

$ npm install eslint-plugin-no-new-instance --save-dev

Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-no-new-instance globally.

Usage

Add no-new-instance to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "no-new-instance"
    ]
}

Then configure the rules you want to use under the rules section.

{
    "rules": {
        "no-new-instance/no-new-instance": ["error", ["Event", "AnotherClass"]]
    }
}

When using this rule the following code is a considered problem:

window.dispatchEvent(new Event('resize'));

The following code is considered okay:

window.dispatchEvent(new CustomEvent('resize'));
