Quick Start

Requirements

• npm or Yarn
• Node.js
• Next.js 9.5+

Installation

npm install next-safe

# OR

yarn add next-safe

Usage

next-safe exports a single function that generates all of your headers. In your next.config.js file, you can pass these directly into the headers key for any route you want to set the headers on.

const nextSafe = require("next-safe");

const isDev = process.env.NODE_ENV !== "production";

module.exports = {
  async headers() {
    return [
      {
        source: "/:path*",
        headers: nextSafe({ isDev })
      }
    ];
  }
};

By default, this sets all of the headers you need and provides substantial protections for your Next.js application. However, the defaults are also super strict. See the Configuration section for details on how to make next-safe a bit more flexible.
