Classes

Sizium

Represents the main class for handling package size.

Examples

const size = new Sizium( 'chalk' )
const data = await size.get()

console.log(data) // all data
console.log(data.size) // total size on bytes

// Directory input
const size = new Sizium( './' )
const data = await size.get()

// package.json input
const size = new Sizium( './package.json' )
const data = await size.get()

// remote package.json input
const size = new Sizium( 'https://raw.githubusercontent.com/chalk/chalk/refs/heads/main/package.json' )
const data = await size.get()

// package.json string input
const pkg = {name: 'chalk', ... }
const size = new Sizium(JSON.stringify(pkg) )
const data = await size.get()

Returns

SiziumResponse

Set Signature

set value(value: SiziumResponse): void

The package information to be filtered and sorted.

Parameters

Parameter	Type
value	SiziumResponse

Returns

void

Constructors

new SiziumFilter()

new SiziumFilter(value?: SiziumResponse): SiziumFilter

Parameters

Parameter	Type
value?	SiziumResponse

Returns

SiziumFilter

Methods

filter()

filter(filter: string): SiziumFilteredResponse

Filters the packages by the given filter string. If no filter string is given, the original package list is returned.

Parameters

Parameter	Type	Description
filter	string	The filter string.

Returns

SiziumFilteredResponse

An object with the original package list and a filtered list of packages that have a name that matches the given filter string (case-insensitive).

Throws

An error if this.value is undefined.

find()

find(input: string | {
  name: string;
  version: string;
 }): undefined | PackageInfo

Finds a package in the package list by its name and/or version. If only the name is given, the first package with that name is returned. If the version is also given, the package with that name and version is returned. If no package is found, undefined is returned.

Returns

undefined | PackageInfo

The package that matches the input or undefined if no package is found.

Examples

find( 'chalk' ) // finds the latest version of the chalk package

find( 'chalk@^5' ) // finds the latest version of the chalk package that satisfies the version constraint

find( { name: 'chalk', version: '5.0.0' } ) // finds the chalk package with version 5.0.0

find( { name: 'chalk', version: '^4.0.0' } ) // finds the chalk package with a version that satisfies the version constraint
