What is this?

This package throws a given error.

When should I use this?

Use this package if you’re building some scripts that might theoretically get errors but frequently don’t and you keep writing if (error) throw error over and over again and you’re just really done with that.

Install

This package is ESM only. In Node.js (version 12.20+, 14.14+, or 16.0+), install with npm:

npm install bail

In Deno with Skypack:

import {bail} from 'https://cdn.skypack.dev/bail@2?dts'

In browsers with Skypack:

<script type="module">
  import {bail} from 'https://cdn.skypack.dev/bail@2?min'
</script>

Use

import {bail} from 'bail'

bail()

bail(new Error('failure'))
// Error: failure
//     at repl:1:6
//     at REPLServer.defaultEval (repl.js:154:27)
//     …

API

Types

Compatibility

ensure-error

While `ensure-error` is focused on ensuring that values are instances of Error, it shares the goal of simplifying error handling in JavaScript applications with `bail`. `ensure-error` can be used in conjunction with error handling mechanisms to ensure that all errors passed through the application's flow are properly instances of Error, complementing `bail`'s straightforward error throwing approach.
