# Slot text A React component in [Beamline](https://beamline.io/)'s [Content & display](https://beamline.io/components/display) category. Live demo: https://beamline.io/components/slot-text Text and numbers that roll into their new value on reels, digit by digit from the right; other characters fade. Read as plain text by assistive tech. ## Use it for - A figure that changes now and then: a total, a price, a status word. ## Not for - Values changing several times a second (plain tabular text). ## Anatomy - isolated value root (content direction independent of page layout) - reels - sr-only value ## States - rest - rolling - RTL page (numeric order and content direction preserved) ## Keyboard - Not interactive ## Motion Reels roll over 700 ms with a 40 ms stagger; reduced motion swaps the value. ## Props | Prop | Type | Default | Description | | --- | --- | --- | --- | | `value / format` | `string \| number / (n) => string` | — | | | `duration / stagger / spins` | `number` | — | | | `align` | `"start" \| "end"` | — | | | `announce` | `boolean` | — | | | `dir` | `"ltr" \| "rtl" \| "auto"` | — | Text direction of the isolated value. Numeric values and digit/punctuation-only strings default to ltr; other text uses auto so an RTL page does not reverse Latin labels. | | `style / ref` | `CSSProperties / native Ref` | — | native HTMLSpanElement | | `classNames` | `SlotTextClassNames` | — | | ## Dependencies `motion` ## Import ```tsx import { SlotText } from "@/components/slot-text/slot-text"; ``` ## Get it Slot text is part of Beamline: 190 React components and screens your coding agent (Claude Code, Codex, Cursor or any MCP client) installs into your app through Beamline's MCP server, as a ready-built package or as plain React source you can change. $49 one payment (regular $200), no subscription, a year of updates, one licence for your whole team.
