Static

Renders items that are written to the terminal once and never updated. Useful for logs, progress outputs, or any content that should remain visible while the main UI updates below.

Import

import { Static } from "silvery"

Usage

<Static items={logs}>{(log, index) => <Text key={index}>{log}</Text>}</Static>

Props

Prop	Type	Default	Description
items	T[]	required	Array of items to render
children	(item: T, index: number) => ReactNode	required	Render function called for each item
style	Record<string, unknown>	-	Style props to apply to the container

Examples

Log Output

const [logs, setLogs] = useState<string[]>([])

function addLog(message: string) {
  setLogs(prev => [...prev, `[${new Date().toISOString()}] ${message}`])
}

// Logs appear above and scroll up as new ones are added
<Static items={logs}>
  {(log, index) => (
    <Text key={index} color="gray">{log}</Text>
  )}
</Static>

// Main UI stays at the bottom
<Box borderStyle="single">
  <Text>Current status: processing...</Text>
</Box>

Output (logs scroll up, status bar stays at bottom):

[2024-01-15T10:30:01.000Z] Loading configuration

Build Progress

interface BuildStep {
  name: string
  status: "success" | "error"
  duration: number
}

const [completedSteps, setCompletedSteps] = useState<BuildStep[]>([])

<Static items={completedSteps}>
  {(step, index) => (
    <Text key={index}>
      <Text color={step.status === "success" ? "green" : "red"}>
        {step.status === "success" ? "✓" : "✗"}
      </Text>
      {" "}{step.name} ({step.duration}ms)
    </Text>
  )}
</Static>

<Text>Building: {currentStep}...</Text>
