next-approuter-context

Server component of Next.js' AppRouter, which provides a ContextAPI-like mechanism.

Context instances are created for each component tree. Contexts cannot be retrieved from ServerActions functions.

Normally page.tsx -> layout.tsx is executed in this order, but with this library layout.tsx -> page.tsx will be executed in this order.

Sample

app/context.tsx

Name the context so that it can be identified when retrieving data

import { createMixContext } from "next-approuter-context";

export const context1 = createMixContext<{ text: string; color: string }>(
  "context1"
);
export const context2 = createMixContext<number>("context2");

app/layout.tsx

Set data in Provider

import { context1, context2 } from "./context";

export default function RootLayout({
  children,
}: {
  children: React.ReactNode;
}) {
  return (
    <html lang="en">
      <body>
        <context1.Provider
          value={{ text: "Send colors and text from Layout", color: "red" }}
        >
          <context2.Provider value={123456}>{children}</context2.Provider>
        </context1.Provider>
      </body>
    </html>
  );
}

app/page.tsx

Place Server/Client components

import { Client } from "./client";
import { Server } from "./server";

const Page = () => {
  return (
    <>
      <Server />
      <Client />
    </>
  );
};

export default Page;

app/server.tsx

Server component handles retrieving values from context

"use server";

import { context1, context2 } from "./context";
import { getMixContext } from "./next-approuter-context";

export const Server = async () => {
  const { text, color } = await getMixContext(context1);
  const value = await getMixContext(context2);
  return (
    <>
      <div style={{ color }}>
        Server: {text} - {value}
      </div>
    </>
  );
};

app/client.tsx

Client component handles retrieving values from context

"use client";

import { useMixContext } from "next-approuter-context";
import { context1, context2 } from "./context";

export const Client = () => {
  const { text, color } = useMixContext(context1);
  const value = useMixContext(context2);
  return (
    <>
      <div style={{ color }}>
        Client: {text} - {value}
      </div>
    </>
  );
};
