Framework integrations

These guides show the idiomatic way to wire the ISA SDK into a specific
framework: where to construct the client, how to share it across
requests, how to handle activation and reference data, and how to verify
webhooks against the raw request body.

Each guide assumes you have read the language quickstart for your stack
(Go, TypeScript,
Python, PHP,
C#) and want the framework-specific composition.

TypeScript / JavaScript

• Vue 3 — Composition API, useIsa() composable,
  reactive datasets.
• React — context provider, custom hooks,
  error boundary.
• Next.js — App Router, Server Actions,
  server-only credentials, Edge runtime caveats.
• Express — singleton at boot, raw-body
  webhook verification, error middleware.
• NestJS — module, injectable IsaService, webhook controller.

Python

• Django — AppConfig singleton, class-based views, webhook blueprint.
• FastAPI — lifespan singleton, dependency injection, async webhook.
• Flask — application factory, g-style singleton, webhook blueprint.

Go

• Gin — dependency struct, ShouldBindJSON, constant-time webhook verification.
• Echo — dependency struct, Bind, constant-time webhook verification.
• net/http — ServeMux, method-pattern routing (Go 1.22+), no third-party router.
• AWS Lambda — package-level singleton, API Gateway proxy, separate webhook function.

PHP

• Laravel 11 — service provider, facade,
  queued idempotency, webhook controller.

.NET

• ASP.NET Core 8 — DI singleton, exception
  filter, background webhook fan-out.
• Azure Functions — isolated worker, DI singleton, FixedTimeEquals webhook verification.
• Console / Worker Service — plain console and BackgroundService patterns.
