Build a custom React component in the bestax/Bulma style. In an app using @allxsmith/bestax-bulma — compose existing components, helper props, public hooks (useBulmaClasses, usePrefixedClassNames), and --bulma-* CSS variables. In the bestax monorepo — the full component pipeline (SCSS partial, stories, tests, docs, wiring). Use when creating a component beyond stock Bulma or extending one.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Building a custom component the bestax way

This skill teaches how to build a component that isn't in the library — composed from bestax
pieces in an app, or as a full library "extra" inside the bestax monorepo.

## Which context are you in?

- **The bestax monorepo** (the repo contains `bulma-ui/src/`) → follow
  `references/library-contributor.md` instead of this file: five-file layout, SCSS partial,
  stories, jest tests, docs page, wiring.
- **An app depending on `@allxsmith/bestax-bulma`** (e.g. scaffolded by `npm create bestax`) →
  continue here. Everything below assumes public package imports and a plain Vite app.

For **form** components (Field/Control/Input/etc.) use the `bestax-form` skill instead.

## Check for an existing component first

Before building anything, **search the library for a component that already does this — or a
close synonym** — and tell the user what you found. Many requests are covered by an existing
element, or are best built by composing existing ones. Building a near-duplicate (a "label" when
`Tag` exists, a "banner" when `Notification` exists) fragments the API and is usually the wrong
call.

How to install

The exact contents, by fingerprint

mdr add allxsmith/bestax/bestax-custom-component@sha256:f89079c41374f67e

The line at the top of this page pins the label git:20261016.7549699, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
