next-https

This is a simple HTTPS proxy to be used with Next.js in local development.

Motivation

A secure HTTP connection is necessary when interfacing with certain Web APIs restricted to secure contexts. This package simply starts an HTTP proxy pointing at your Next.js server instance to simplify local development.

Getting Started

Install the package

yarn add next-https

Inside your Next.js configuration file:

// next.config.js
const useHttps = require("next-https");

// You can pass options here
const withHttps = useHttps({
  enabled: process.env.NODE_ENV === "development",
});

// pass your Next.js options here
module.exports = withHttps({
  reactStrictMode: true,
});

NOTE: When using the default configuration options, you'll have to accept the self-signed certificate the first time you access the page. This is safe to do in a local development environment only.

Configuration

You can use next-https with default configuration options.

name	required	description
enabled	no	Defaults to process.env.NODE_ENV === 'development'
host	no	Next.js server hostname, defaults to localhost
target	no	Next.js port target, defaults to 3000
key	no	Path to the key, defaults to this package's key file
cert	no	Path to the certificate, defaults to this package's cert file

Using custom certificates

If you want to use a custom domain name or to remove the initial warning from your browser, you'll need to setup your own certificates.

To avoid the warnings you need to install the local root CA in your computer in order for your browser to trust the certificates.

For this you can use mkcert

brew install mkcert

Install the local CA

mkcert -install

Create the certificate files

mkcert example.com "*.example.com" example.test localhost 127.0.0.1 ::1

And pass your custom certificate and key

// next.config.js
const nextHttps = require("next-https");

// You can pass options here
const withHttps = nextHttps({
  host: "example.com",
  key: './path/to/example-key.pem'),
  cert: './path/to/example-cert.pem'),
});

// pass your Next.js options here
module.exports = withHttps({
  reactStrictMode: true,
});
