eslint-plugin-switch-statement

Rules for making switch/case expressions for union type values exhaustively checkable at compile time.

Installation

Install eslint-plugin-switch-statement. If you want to use the included assertUnreachable in your source
code, make sure to save it as a dependency and not a devDependency.

``sh
npm install eslint-plugin-switch-statement --save-dev
`

Usage

`ts
import exhaustiveSwitch from "eslint-plugin-switch-statement";

// in your eslint flat config
{
"plugins": { "exhaustive-switch": exhaustiveSwitch }
}
`

Then configure the rule under the rules section.

`json
{
"rules": {
"exhaustive-switch/require-unreachable-default-case": [
2,
{ "unreachableDefaultCaseAssertionFunctionName": "assertNever" }
]
}
}
`

Rules

🔧 Automatically fixable by the --fix` CLI option.
