utils

Shared TypeScript utilities for removing repeated code across Sovereignbase codebases.

Compatibility

• Runtimes: modern JavaScript runtimes; the repository includes runtime compatibility tests for Node, Bun, Deno, Cloudflare Workers, Edge Runtime, and browsers.
• Module format: ESM and CommonJS.
• Required globals / APIs: structuredClone is required for successful safeStructuredClone() results.
• TypeScript: bundled types.

Goals

• Remove repeated utility code from Sovereignbase repositories.
• Keep shared helpers small, explicit, and side-effect free.
• Validate behavior across the runtimes used in Sovereignbase projects.

Installation

npm install @sovereignbase/utils
# or
pnpm add @sovereignbase/utils
# or
yarn add @sovereignbase/utils
# or
bun add @sovereignbase/utils
# or
deno add jsr:@sovereignbase/utils
# or
vlt install jsr:@sovereignbase/utils

Usage

prototype()

import { prototype } from '@sovereignbase/utils'

prototype(null) // 'null'
prototype({ ok: true }) // 'record'
prototype(new URL('https://sovereignbase.dev')) // 'url'

Returns a normalized lowercase runtime tag for common primitives, serializable built-ins, and selected platform objects.

isUuidV7()

import { isUuidV7 } from '@sovereignbase/utils'

const value = '018f0d1e-6c82-7d4b-91c1-8a7b5e2f4a10'

if (isUuidV7(value)) {
  value // string, confirmed UUID v7
}

Checks that a value is a syntactically valid UUID version 7 string.

safeStructuredClone()

import { safeStructuredClone } from '@sovereignbase/utils'

const result = safeStructuredClone({ ok: true, nested: { count: 1 } })

if (result[0]) {
  const clone = result[1]
  clone // deep cloned value
}

Attempts a structured clone and returns a tuple instead of throwing on unsupported values.
