@backpackjs/head NPM

@backpackjs/head

A pre build-time backpack plugin that auto generates and writes multiple head react components to storefront/src/head on every build.

This plugin is executed by @backpackjs/nextjs-backpack-init

The components structure is derived based on the configuration provided .via/backpack.head.js(or its default config). These global components are also already pre-imported in the projectsrc/head/index.jsx` component which is included in the via next/head

React components generated:

Metas.jsx - title, description etc..
Fonts.jsx - Custom or/and google font faces and link tags
Preconnects.jsx - dns-prefetches and pre-connects
Libs.jsx - and tags for all js and css third-party defined in the configuration

Example Fonts.jsx
