size-satisfies

Same as SemVer.satisfies but for file size!

Requirements

• Node.js v20 or higher

Getting Started

This package is available in the Node Package Repository and can be easily installed with npm or yarn.

$ npm i @nodesecure/size-satisfies
# or
$ yarn add @nodesecure/size-satisfies

Usage example

import { strict } from "assert";
import sizeSatisfies from "size-satisfies";

const { strictEqual } = strict;

strictEqual(sizeSatisfies(">= 45KB", "20MB"), true);
strictEqual(sizeSatisfies("= 1MB", "1MB"), true);
strictEqual(sizeSatisfies("= 1MB", 2000), false);

The first argument of the sizeSatisfies method is the pattern with the operator + size. Available operators are >=, <=, >, <, =.

API

sizeSatisfies(pattern: string, size: number | string): boolean

When the size is a string we convert it to a bytes number. When the argument is a number we consider the value as bytes.

Invalid pattern will always return false.
