News: javascripts.store Launches Component Marketplace for Micro-UIs

Today we launched a new marketplace aimed at helping engineering teams discover, purchase, and integrate production-ready JavaScript micro-components. The marketplace focuses on accessibility, design-token compatibility, and long-term maintenance guarantees. With the proliferation of micro-frontends and distributed design systems, teams need reliable, reusable pieces that ship quickly without sacrificing quality.

What we are shipping: The marketplace lists components across categories: data grids, charting components, form atoms, authentication UI, and performance-optimized image loaders. Each listing includes the following: standardized documentation, automated accessibility reports, a build artifact captured with deterministic hashes, and an optional support contract from the author.

Why a marketplace?

Teams frequently re-invent common UI elements. The marketplace helps reduce duplication by curating components that pass a baseline of quality checks. We require all sellers to submit automated a11y reports, provide a migration guide, and pin peer dependencies. Buyers receive a clear upgrade path and a support channel for security or performance issues.

“We built the marketplace because we saw a gap between experimental components and production-grade integrations.”

— Maya Chen, Product Lead

Security and verification

Security is a key focus. Each component undergoes static analysis, dependency auditing, and signed artifact release. Buyers can view a security summary and a report of transitive dependencies. We also provide an optional vulnerability monitoring subscription that alerts buyers when critical transitive dependencies require updates.

Design-token compatibility

To integrate with corporate design systems, listings include a token mapping guide. Authors can provide theme adapters for common token models (CSS variables, JSON tokens, Theme UI). This reduces friction when adopting components across applications with different theming mechanisms.

Support and SLAs

Many marketplace listings offer optional support plans with SLAs, patch guarantees, and upgrade assistance. Support plans are provided by authors or third-party integrators and allow teams to buy a contractual level of maintenance for mission-critical components.

Launch partners

At launch, we partnered with several respected component authors and small studios that specialize in accessible UI. Early listings include a virtualized data grid optimized for large datasets, a composable charting toolkit, and an authentication UI with multiple providers prewired.

How to get started

For buyers: browse by category, view the health checks and audits, and install using the provided package spec. For authors: submit your component with the required documentation, and pass the automated checks. Authors can opt into co-marketing programs and commercial support lanes.

Closing

We aim to make component adoption safer and faster. If you build or maintain components, consider listing them—quality components with clear documentation and support will get preferential placement. If you are looking to accelerate a product launch, explore the marketplace to find audited pieces you can trust.
