eslint-plugin-chai-friendly

eslint-plugin-chai-friendly

This plugin overrides no-unused-expressions to make it friendly towards chai expect statements.

// this
expect(foo).to.be.true;

// instead of this
expect(foo).to.be.true; // eslint-disable-line no-unused-expressions

Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-chai-friendly:

$ npm install eslint-plugin-chai-friendly --save-dev

Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-chai-friendly globally.

Usage

Add chai-friendly to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "chai-friendly"
    ]
}

Then disable original no-unused-expressions rule and configure chai-friendly replacement under the rules section.

{
    "rules": {
        "no-unused-expressions": 0,
        "chai-friendly/no-unused-expressions": 2
    }
}
