API

npmName(name, options?)

Check whether a package/organization name is available (not registered) on npm.

An organization name should start with @ and should not be a scoped package.

Returns a Promise<boolean> of whether the given name is available.

name

Type: string

Name to check.

options

Type: object

registryUrl

Default: User's configured npm registry URL.

Registry URL to check name availability against.

Note: You're unlikely to need this option. Most use-cases are best solved by using the default. You should only use this option if you need to check a package name against a specific registry.

npmName.many(names, options?)

Check whether multiple package/organization names are available (not registered) on npm.

Returns a Promise<Map> of name and status.

names

Type: string[]

Multiple names to check.

options

Type: object

Same as npmName().
