Prevent default fetch() behaviours
You'll first need to install ESLint:
$ npm i eslint --save-dev
Next, install eslint-plugin-fetch-options:
$ npm install eslint-plugin-fetch-options --save-dev
Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-fetch-options globally.
Add fetch-options to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:
{
    "plugins": [
        "fetch-options"
    ]
}
Then configure the rules you want to use under the rules section.
{
    "rules": {
        "fetch-options/no-fetch-credentials": 2
    }
}
