is-alphanumerical

Build Coverage Downloads Size

Check if a character is alphanumerical.

Contents

What is this?

This is a function that checks if a given character is ASCII alphanumerical: it matches [a-zA-Z0-9].

When should I use this?

Not often, as its relatively simple to do yourself. This package exists because its needed in several related packages, at which point it becomes useful to defer to one shared function.

Install

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

npm install is-alphanumerical

In Deno with Skypack:

import {isAlphanumerical} from 'https://cdn.skypack.dev/is-alphanumerical@2?dts'

In browsers with Skypack:

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

Use

import {isAlphanumerical} from 'is-alphanumerical'

isAlphanumerical('a') // => true
isAlphanumerical('Z') // => true
isAlphanumerical('0') // => true
isAlphanumerical(' ') // => false
isAlphanumerical('💩') // => false

API

This package exports the following identifier: isAlphanumerical. There is no default export.

isAlphanumerical(character)

Check whether the given character code (number), or the character code at the first position (string), is alphanumerical.

Types

This package is fully typed with TypeScript.

Compatibility

This package is at least compatible with all maintained versions of Node.js. As of now, that is Node.js 12.20+, 14.14+, and 16.0+. It also works in Deno and modern browsers.

Security

This package is safe.
