:sparkles: Features

• :zap: Multi runtime support (Deno, Node.js)
• :books: Pure TypeScript and provides type definition
• :package: Optimized, super slim size
• :page_facing_up: TSDoc-style comments

Currently providing validators for the following package registries: Check each for detailed validation rules.

• npm
• deno.land
• nest.land

:zap: Overview

isValid*

The isValid* function returns a boolean if the package name is valid as a package.

isValidNpm('is-valid-package-name') // true
isValidNpm('node_modules') // false

isValidDenoLand('is_valid') // true
isValidDenoLand('is-valid') // false

isValidNestLand('oak') // true
isValidNestLand('o') // false

validate*

The validate* function returns tuple of boolean and error message.

validateNpm('is-valid-package-name') // [ true, "" ]
validateNpm('node_modules') // [ false, "Name is blacklisted" ]

validateDenoLand('is_valid') // [ true, "" ]
validateDenoLand('is-valid') // [ false, "Name contains only the characters a-z, 0-9 and _" ]

validateNestLand('oak') // [ true, "" ]
validateNestLand('o') // [ false, "Name length must be greater than 1" ]

import { isValidNpm ,validateNpm, isValidDenoLand, validateDenoLand, isValidNestLand, validateNestLand } from "https://x.nest.land/is_valid_package_name/mod.ts";

:package: Node.js

Install

npm i is-valid-package-name
or

:globe_with_meridians: Browser

The module that bundles the dependencies is obtained from skypack.
