brand-ui — MessageEdit

import { MessageEdit } from "@elabs-ai/components-ai";

Install

npm install @elabs-ai/components-tokens @elabs-ai/components-ui @elabs-ai/components-ai

Skipping the @source line is the most common first failure: Tailwind does not scan node_modules, so every component renders unstyled. The one-time wiring

Add the brand-ui MessageEdit component (from @elabs-ai/components-ai) to this project.

1. Read https://elabs-ai.com/llms.txt first: it maps every package and the rules. If you can use MCP servers, connect https://elabs-ai.com/mcp and use its search, docs and tokens tools. If not, run the same lookups in the terminal: `npx -y @elabs-ai/components-cli search "<what you need>"` and `npx -y @elabs-ai/components-cli docs <Component>`.
2. Look MessageEdit up before writing code: `npx -y @elabs-ai/components-cli docs MessageEdit` prints its real props, variants, what it pairs with and what to avoid.
3. If @elabs-ai/components-ai is not installed yet: `pnpm add @elabs-ai/components-tokens @elabs-ai/components-ui @elabs-ai/components-ai` (or `npm install @elabs-ai/components-tokens @elabs-ai/components-ui @elabs-ai/components-ai`). If this is the first brand-ui package in the project, wire it once: import `@elabs-ai/components-tokens/styles.css` plus the `themes/light.css` and `themes/dark.css` stylesheets in the CSS entry, add one Tailwind `@source` line per installed @elabs-ai package (Tailwind does not scan node_modules, so without it everything renders unstyled), and wrap the app root in `ThemeProvider` from `@elabs-ai/components-tokens`.
4. Use it here: [the screen or file, and what it should show]
5. Rules: use only @elabs-ai/components-* components and the semantic tokens — no raw colours, no raw font sizes, no arbitrary Tailwind values. Look up each component's real props with the docs tool before you use it; never guess a prop.
6. Done means: the typecheck passes, `npx -y @elabs-ai/components-cli audit src --strict` reports nothing, and you have opened the app and looked at every screen you touched in the light and the dark theme.

Avoid

Mutating the original message on edit — it emits `onEditSubmit(newText)`; the consumer creates a branch.
Leaving the edited turn as the only history — pair it with MessageBranch so the earlier version stays reachable.
Re-implementing the key handling — Enter submits, Shift+Enter newlines, Esc cancels, and focus returns to the trigger.

Examples

5 live examples

Editing

Editing — starts in edit mode (Enter saves · Shift+Enter newline · Esc cancels).

Trigger in a toolbar — compose the parts so the edit control lives elsewhere.

Branch On Edit

Branch on edit — editing creates a new version. The consumer owns branch state; here each save appends a version and jumps to it (compose with `MessageBranch*` in production).

Dark Theme

Dark theme — inline editor + trigger in dark.
