getUniqueTypes

Get the unique project types present in a list of projects, in canonical order.

Signature

function getUniqueTypes(projects: ProjexProject[]): ProjectType[]

Parameters

Parameter	Type	Description
projects	ProjexProject[]	Array of projects to scan

Returns

ProjectType[] - Unique types present in projects (new array, does not mutate input)

Behavior

• Only types with at least one project are included
• Order follows the canonical PROJECT_TYPES order, not first-seen order, so filter UIs render consistently regardless of input order
• Returns an empty array if projects is empty

Example

import { getUniqueTypes } from '@manningworks/projex'

// Only the types that actually occur, in canonical order
const types = getUniqueTypes(projects)
// e.g. ['github', 'npm', 'hybrid']

PROJECT_TYPES Constant

The canonical type order, exported alongside getUniqueTypes for building custom filter UIs:

const PROJECT_TYPES = [
  'github',
  'manual',
  'npm',
  'product-hunt',
  'youtube',
  'gumroad',
  'lemonsqueezy',
  'devto',
  'hybrid',
] as const
