Corex.Clipboard (Corex v0.1.2)

Phoenix implementation of Zag.js Clipboard.

Set value for the initial string to copy. Use Corex.Clipboard.set_value/2 or corex:clipboard:set-value to change it on the client.

Anatomy

Minimal

<.clipboard class="clipboard" value="hello@example.com">
  <:label>Email</:label>
  <:copy>
    <.heroicon name="hero-clipboard" />
  </:copy>
  <:copied>
    <.heroicon name="hero-check" />
  </:copied>
</.clipboard>

Trigger only

<.clipboard
  class="clipboard"
  value="https://example.com/share"
  input={false}
  trigger_aria_label="Copy link"
>
  <:copy>
    <.heroicon name="hero-clipboard" />
  </:copy>
  <:copied>
    <.heroicon name="hero-check" />
  </:copied>
</.clipboard>

API

Requires a stable id on <.clipboard>.

Function	Action	Returns

`copy/2`	Copy current value (server)	`socket`
`set_value/2`	Set value to copy (client)	`%Phoenix.LiveView.JS{}`
`set_value/3`	Set value to copy (server)	`socket`

Events

Pick an event name and pass it to on_* on <.clipboard>.

Server events

Event	When	Payload
`on_copy="clipboard_copied"`	User copies	`%{"id" => id, "value" => value}`

on_copy

<.clipboard
  class="clipboard"
  value="info@netoum.com"
  on_copy="clipboard_copied"
>
  <:label>Copy</:label>
  <:copy>
    <.heroicon name="hero-clipboard" />
  </:copy>
  <:copied>
    <.heroicon name="hero-check" />
  </:copied>
</.clipboard>

def handle_event("clipboard_copied", %{"value" => value, "id" => _id}, socket) do
  {:noreply, assign(socket, :last_copied, value)}
end

Client events

Event	When	`event.detail`
`on_copy_client="clipboard-copied"`	User copies	`id`, `value`

Style

Target parts with data-scope and data-part, or use Corex Design: import tokens and clipboard.css, then set class="clipboard" on <.clipboard>.

[data-scope="clipboard"][data-part="root"] {}
[data-scope="clipboard"][data-part="trigger"] {}
[data-scope="clipboard"][data-part="control"] {}
[data-scope="clipboard"][data-part="input"] {}
[data-scope="clipboard"][data-part="copy"] {}
[data-scope="clipboard"][data-part="copied"] {}

@import "../corex/main.css";
@import "../corex/tokens/themes/neo/light.css";
@import "../corex/components/clipboard.css";

Stack modifiers on the host (class on <.clipboard>).
