Core Concept

Zero-Latency Normalization

Boundary removes the need for "glue code" by enforcing a strict schema on API inputs/outputs.

The Problem

API A returns { user_id }, API B returns { id }. This fragmentation breaks apps.

The Solution

Boundary standardizes these into a single, predictable interface with consistent type safety.

Code Comparison

normalization_demo.ts

// Without Boundary
const userA = await apiA.fetchUser(); // { user_id: "123" }
const userB = await apiB.fetchUser(); // { id: "456" }

// With Boundary
const userA = await boundary.users.get("123"); // { id: "123" }
const userB = await boundary.users.get("456"); // { id: "456" }
