Headless Expense Tracker

A headless, framework-agnostic expense tracker with localStorage persistence, category management, and analytics.

What is HelpU Finance?

HelpU Finance is a free, privacy-first platform with financial tools and educational resources. No tracking, no data collection.

We believe that financial literacy should be accessible to everyone.

Installation

npm install @helpu/headless-expense-tracker

Usage

import { calculateExpenseSummary, createExpense } from '@helpu/headless-expense-tracker'

const result = createExpense({
  description: 'Groceries',
  amount: 85,
  category: 'food',
  date: '2026-01-15',
  paymentMethod: 'debit',
})

if (result.success) {
  const summary = calculateExpenseSummary([result.data])
  console.log(summary.totalAmount)
  console.log(summary.categoryBreakdown)
} else {
  console.error(result.error.message)
}

Use MemoryStorageAdapter or LocalStorageAdapter when you need persistence, and combine the filtering, sorting, and summary helpers for your application’s UI.
