next-extra is a utility package that allows you to enhance your Next.js projects with additional methods not found in the core package.
npm install next-extra
function createAction(fn: Function): ActionFunc;
function actionError(code: string, message: string): never;
function cookies(): ResponseCookies;
function clientIP(): Promise<string | null>;
// -- actions.ts
'use server';
import { actionError, createAction } from 'next-extra/action';
export const hello = createAction(async (name: string) => {
if (!name) {
actionError('NAME_REQUIRED', 'Name is required');
}
return `Hello, ${name}!`;
});
// -- page.tsx
import { hello } from './actions';
export default async function Page() {
const { data, error } = await hello('John');
if (error) {
return <h1>ERROR: {error.message}</h1>;
}
return <h1>{data}</h1>;
}
This module provides utilities for passing serializable data from the server layout to client page components in the Next.js App Router. It is particularly useful for sharing context-specific data across your application without the need to re-fetch data, thereby saving computing resources and improving performance.
function PageContext<T>(props: PageContextProps<T>): JSX.Element;
function usePageContext<T>(): Readonly<T>;
function useServerInsertedContext<T>(): Readonly<T | undefined>;
// -- layout.tsx
import { PageContext } from 'next-extra/context';
export default async function RootLayout({ children }: { children: React.ReactNode }) {
return <PageContext data={{ ts: Date.now() }}>{children}</PageContext>;
}
// -- quotes/layout.tsx
import { PageContext } from 'next-extra/context';
export default async function Layout({ children }: { children: React.ReactNode }) {
return <PageContext data={{ quote: 'Guillermo Rauch is a handsome dude!' }}>{children}</PageContext>;
}
// -- quotes/page.tsx
'use client';
import { useServerInsertedContext, usePageContext } from 'next-extra/context';
interface Context {
message: string;
}
interface InsertedContext extends Context {
ts: number;
}
export default function Page() {
const insertedCtx = useServerInsertedContext<InsertedContext>();
console.log(insertedCtx); // undefined in server or Object { ts: ..., message: "..." }
const ctx = usePageContext<Context>();
console.log(ctx); // Object { message: "..." }
return <h3>Message: {ctx.message}</h3>;
}
Access pathname
and searchParams
of the incoming request for server-side components in the App Router.
function pathname(): Promise<string>;
function searchParams(): Promise<ReadonlyURLSearchParams>;
import { pathname, searchParams } from 'next-extra/pathname';
export default async function Layout({
children,
}: Readonly<{ children: React.ReactNode }>) {
// Assuming a request to "/hello?name=John"
const route = await pathname(); // /hello
const params = await searchParams(); // ReadonlyURLSearchParams { 'name' => 'John' }
return children;
}
