Creating `AudioContext` in Next.js

I've had quite a lot of trouble creating an

AudioContext

AudioContext

AudioContext

AudioContext object in my nextjs project. I'm expanding on the ReactFlow Audio API guide https://reactflow.dev/learn/tutorials/react-flow-and-the-web-audio-api which uses ReactFlow as a UI to connect

AudioNode

AudioNode

AudioNodes.

I have a component that contains my ReactFlow component that I dynamically load in with

{ssr: false}

{ssr: false}

{ssr: false}

{ssr: false} on a page. There's a snippet at the top of the flow file

// flow.tsx
let ctx: AudioContext | undefined = undefined;
if (typeof window !== "undefined") {
  ctx = new AudioContext();
}
export default function Flow() {
  if (!ctx) {
    return null;
  }  
  store.setup({ctx})
  // ...
}

// flow.tsx
let ctx: AudioContext | undefined = undefined;
if (typeof window !== "undefined") {
  ctx = new AudioContext();
}
export default function Flow() {
  if (!ctx) {
    return null;
  }  
  store.setup({ctx})
  // ...
}

// flow.tsx
let ctx: AudioContext | undefined = undefined;
if (typeof window !== "undefined") {
  ctx = new AudioContext();
}
export default function Flow() {
  if (!ctx) {
    return null;
  }  
  store.setup({ctx})
  // ...
}

// flow.tsx
let ctx: AudioContext | undefined = undefined;
if (typeof window !== "undefined") {
  ctx = new AudioContext();
}
export default function Flow() {
  if (!ctx) {
    return null;
  }  
  store.setup({ctx})
  // ...
}

(that I think should only run once, but I'm not sure)

// page.tsx
"use client";

import dynamic from "next/dynamic";

const DynamicFlow = dynamic(() => import("~/components/flow"), {
  loading: () => <div>Loading</div>,
  ssr: false,
});

export default function FlowPage() {
  return <DynamicFlow />;
}

// page.tsx
"use client";

import dynamic from "next/dynamic";

const DynamicFlow = dynamic(() => import("~/components/flow"), {
  loading: () => <div>Loading</div>,
  ssr: false,
});

export default function FlowPage() {
  return <DynamicFlow />;
}

// page.tsx
"use client";

import dynamic from "next/dynamic";

const DynamicFlow = dynamic(() => import("~/components/flow"), {
  loading: () => <div>Loading</div>,
  ssr: false,
});

export default function FlowPage() {
  return <DynamicFlow />;
}

// page.tsx
"use client";

import dynamic from "next/dynamic";

const DynamicFlow = dynamic(() => import("~/components/flow"), {
  loading: () => <div>Loading</div>,
  ssr: false,
});

export default function FlowPage() {
  return <DynamicFlow />;
}

There isn't a lot of documentation on this, I've read

In some parts of my zustand store I need to use the context

// store.ts
// ...
const node = context.createOscillator();

// store.ts
// ...
const node = context.createOscillator();

// store.ts
// ...
const node = context.createOscillator();

// store.ts
// ...
const node = context.createOscillator();

What/where is the best way to construct an

AudioContext

AudioContext

AudioContext

AudioContext object, and is there any way for me to always have a valid

AudioContext

AudioContext

AudioContext

AudioContext in my zustand store?
