Next Export Lang

A simple npm package to add the HTML lang attribute to all export files after building to satisfy the Lighthouse accessibility rule for SEO.

Installation and Usage

Global CLI Usage

1. Run npm install -g next-export-lang
2. Example: run next-export-lang en-US when in a Next.JS project after running the next export command to add HTML 'lang' attributes to all HTML files in the 'out' folder.

Local Project Installation

The next-export-lang package can be installed in a Node project so it can be integrated as part of your build process.

1. Run npm install -D next-export-lang
2. Add next-export-lang to your build command (after next export). For example, in your package.json, update your build script, adding && next-export-lang en to the end, replacing 'en' with the language you want to add to your HTML files: "build": "next export && next-export-lang".

A lang attribute with the defined language will be added to all HTML files in the 'out' folder generated from the next export command.
