Overview

Halide is a declarative BFF (Backend for Frontend) runtime built on Hono. It standardizes how SPAs communicate with backend services by providing a shared, predictable structure for auth, routing, proxying, and security.

When to use: You have a SPA (Angular, React, Vue, Svelte) and need a BFF layer between it and your backend services.

When not to use: You need direct HTTP layer control, multi-service routing, circuit breakers, load balancing, or TLS termination — use an API gateway or service mesh instead.

Installation

npm install halide

Or use the CLI to scaffold a server:

npx halide init
