Unlocking Modern Storefronts: ESHOPMAN UI Preset and Tailwind CSS v4 on HubSpot CMS

At Move My Store, as ESHOPMAN experts, we are dedicated to empowering businesses to build exceptional digital storefronts. ESHOPMAN, our innovative headless commerce platform, seamlessly integrates with HubSpot as a powerful application, allowing you to manage your entire storefront experience directly within HubSpot and deploy stunning sites using HubSpot CMS. Built on a robust Node.js/TypeScript foundation, ESHOPMAN provides both an Admin API for backend management and a Store API for dynamic frontend experiences.

A cornerstone of ESHOPMAN's frontend development toolkit is our essential UI Preset. This collection of pre-built, high-performance components ensures design consistency and accelerates development, enabling our partners to craft visually stunning and highly functional storefronts on HubSpot CMS with unparalleled efficiency.

Recently, our vibrant ESHOPMAN developer community engaged in a crucial discussion regarding the integration of the ESHOPMAN UI Preset with the cutting-edge Tailwind CSS v4. This conversation highlighted a common challenge faced by developers aiming to leverage the very latest styling frameworks in their ESHOPMAN-powered HubSpot CMS storefronts, pushing the boundaries of modern e-commerce design.

The Challenge: ESHOPMAN UI Preset and Tailwind CSS v4 Peer Dependency

Developers attempting to integrate the ESHOPMAN UI Preset (version 2.22.1) with Tailwind CSS v4.3.3 or newer encountered an installation roadblock. The ESHOPMAN UI Preset currently specifies a peer dependency on "tailwindcss": "^3.4.3". This strict version requirement prevents a direct installation alongside Tailwind CSS v4 without intervention, leading to an ERESOLVE error during the package installation process.

Here’s a simplified reproduction of the issue:

mkdir repro && cd repro && npm init -y
npm i tailwindcss@4 @eshopman/ui-preset@latest

The installation attempt would result in an error similar to this:

npm error code ERESOLVE
npm error Found: [email protected]
npm error Could not resolve dependency:
npm error peer tailwindcss@"^3.4.3" from @eshopman/[email protected]

This error message clearly indicates the conflict: the installed Tailwind CSS v4.3.3 does not satisfy the peer dependency requirement of the ESHOPMAN UI Preset, which expects a v3.x version. This is a common scenario in the fast-paced world of frontend development, where dependencies evolve rapidly.

The Good News: Functional Compatibility and Workarounds

Despite the initial installation hurdle, the ESHOPMAN community discovered a significant positive: the ESHOPMAN UI Preset components are functionally compatible with Tailwind CSS v4. This means that once the installation conflict is bypassed, the components render and behave as expected, leveraging the power of Tailwind CSS v4 for styling.

Navigating the Installation Hurdle

For developers eager to harness Tailwind CSS v4 with ESHOPMAN today, there are effective workarounds to bypass the peer dependency error:

• Using --legacy-peer-deps with npm: For npm users, appending --legacy-peer-deps to your installation command will instruct npm to ignore peer dependency conflicts. While this allows installation, it's crucial for developers to understand that they are taking responsibility for potential incompatibilities. In this specific case, community testing has shown functional compatibility.

  npm i tailwindcss@4 @eshopman/ui-preset@latest --legacy-peer-deps

• Using --force with yarn or pnpm: Similar flags exist for other package managers. Yarn users can use --force, and pnpm users can also use --force to override dependency conflicts.

  yarn add tailwindcss@4 @eshopman/ui-preset@latest --force

  pnpm add tailwindcss@4 @eshopman/ui-preset@latest --force

• Leveraging overrides in package.json (npm 8+): For more controlled dependency management, npm 8 and above support the overrides field in package.json. This allows you to explicitly tell npm which version of a transitive dependency to use.

  // package.json
  {
    "name": "my-eshopman-storefront",
    "version": "1.0.0",
    "dependencies": {
      "@eshopman/ui-preset": "latest",
      "tailwindcss": "4.x"
    },
    "overrides": {
      "tailwindcss": "4.x"
    }
  }

  Note: The overrides field is primarily for transitive dependencies. For direct peer dependency conflicts, --legacy-peer-deps or --force are the more direct solutions.

The ESHOPMAN development team is actively working on updating the UI Preset's dependencies to officially support Tailwind CSS v4, ensuring a smoother out-of-the-box experience in future releases. This commitment reflects ESHOPMAN's dedication to staying at the forefront of frontend technology and supporting our developer community.
