Various utility and helper types for Next.js projects

Usage no npm install needed!

<script type="module">
  import ergodarkNextTypes from 'https://cdn.skypack.dev/@ergodark/next-types';


npm version


This package contains various utility and helper types that can be imported by a Next.js project.

This package only contains TypeScript types. This package also exports all the types from @ergodark/types, so there is no need to install both packages.


npm install @ergodark/next-types


You can use this library's types in your TypeScript projects like so:

import type { TypeNameHere } from '@ergodark/next-types'

const variable: TypeNameHere;
import type * as ErgoDark from '@ergodark/next-types'

const variable: ErgoDark.TypeNameHere;

Type Glossary

Along with the types exposed by @ergodark/types, this library provides the following types:


Represents an object with well-defined NextApiRequest and NextApiResponse properties where generic type T is passed to NextApiResponse<T>.

Specifying T is optional. By default, T = Record<string, unknown>.

import type { NextParamsRR } from '@ergodark/next-types'

export async function addToRequestLog({ req, res }: NextParamsRR) {


Adds a config property to type T. Useful for dealing with Next endpoints that require custom configuration when writing unit tests.

import * as Endpoint from 'pages/api-endpoint'

import type { WithConfig } from '@ergodark/next-types'

const endpoint: WithConfig<typeof Endpoint.default> = Endpoint.default;
endpoint.config = Endpoint.config;
