Rules for safe logical expressions in JSX

Installation

You'll first need to install ESLint:

npm i eslint --save-dev

Next, install eslint-plugin-jsx-expressions:

npm install eslint-plugin-jsx-expressions --save-dev

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

{
  "plugins": ["jsx-expressions"]
}

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

{
  "rules": {
    "jsx-expressions/strict-logical-expressions": "error"
  }
}

jsx-expressions/strict-logical-expressions: Enforces logical "&&" expressions do not use potentially falsey numbers or strings.
