// CJS
const spinners = require('unicode-animations');

示例

CLI 工具 — 异步工作期间的旋转器

import spinners from 'unicode-animations';
const { frames, interval } = spinners.braille;
let i = 0;
const spinner = setInterval(() => {
  process.stdout.write(\r\x1B[2K  ${frames[i++ % frames.length]} Deploying to production...);
}, interval);
await deploy();
clearInterval(spinner);
process.stdout.write('\r\x1B[2K  ✔ Deployed.\n');

可重用的加载动画辅助工具

import spinners from 'unicode-animations';
function createSpinner(msg, name = 'braille') {
  const { frames, interval } = spinners[name];
  let i = 0, text = msg;
  const timer = setInterval(() => {
    process.stdout.write(\r\x1B[2K  ${frames[i++ % frames.length]} ${text});
  }, interval);
  return {
    update(msg) { text = msg; },
    stop(msg) { clearInterval(timer); process.stdout.write(\r\x1B[2K  ✔ ${msg}\n); },
  };
}
const s = createSpinner('Connecting to database...');
const db = await connect();
s.update(Running ${migrations.length} migrations...);
await db.migrate(migrations);
s.stop('Database ready.');

多步骤管道

import spinners from 'unicode-animations';
async function runWithSpinner(label, fn, name = 'braille') {
  const { frames, interval } = spinners[name];
  let i = 0;
  const timer = setInterval(() => {
    process.stdout.write(\r\x1B[2K  ${frames[i++ % frames.length]} ${label});
  }, interval);
  const result = await fn();
  clearInterval(timer);
  process.stdout.write(\r\x1B[2K  ✔ ${label}\n);
  return result;
}
await runWithSpinner('Linting...', lint, 'scan');
await runWithSpinner('Running tests...', test, 'helix');
await runWithSpinner('Building...', build, 'cascade');
await runWithSpinner('Publishing...', publish, 'braille');

React 组件

import { useState, useEffect } from 'react';
import spinners from 'unicode-animations';
function Spinner({ name = 'braille', children }) {
  const [frame, setFrame] = useState(0);
  const s = spinners[name];
  useEffect(() => {
    const timer = setInterval(
      () => setFrame(f => (f + 1) % s.frames.length),
      s.interval
    );
    return () => clearInterval(timer);
  }, [name]);
  return {s.frames[frame]} {children};
}
// Usage: Generating response...

浏览器 — 状态指示器

import spinners from 'unicode-animations';
const el = document.getElementById('status');
const { frames, interval } = spinners.orbit;
let i = 0;
const spinner = setInterval(() => {
  el.textContent = ${frames[i++ % frames.length]} Syncing...;
}, interval);
await sync();
clearInterval(spinner);
el.textContent = '✔ Synced';

所有加载指示器

经典盲文

| 名称 | 预览 | 间隔 | |------|---------|----------| | braille | ⠋ ⠙ ⠹ ⠸ ⠼ ⠴ ⠦ ⠧ ⠇ ⠏ | 80毫秒 | | braillewave | ⠁⠂⠄⡀ → ⠂⠄⡀⢀ | 100毫秒 | | dna | ⠋⠉⠙⠚ → ⠉⠙⠚⠒ | 80毫秒 |

网格动画（盲文）

| 名称 | 帧数 | 间隔 | |------|--------|----------| | scan | 10 | 70毫秒 | | rain | 12 | 100毫秒 | | scanline | 6 | 120毫秒 | | pulse | 5 | 180毫秒 | | snake | 16 | 80毫秒 | | sparkle | 6 | 150毫秒 | | cascade | 12 | 60毫秒 | | columns | 26 | 60毫秒 | | orbit | 8 | 100毫秒 | | breathe | 17 | 100毫秒 | | waverows | 16 | 90毫秒 | | checkerboard | 4 | 250毫秒 | | helix | 16 | 80毫秒 | | fillsweep | 11 | 100毫秒 | | diagswipe | 16 | 60毫秒 |

自定义加载指示器

使用网格工具创建您自己的盲文加载指示器：

import { gridToBraille, makeGrid } from 'unicode-animations';
// Create a 4-row × 4-col grid
const grid = makeGrid(4, 4);
grid[0][0] = true;
grid[1][1] = true;
grid[2][2] = true;
grid[3][3] = true;
console.log(gridToBraille(grid)); // diagonal braille pattern

makeGrid(rows, cols) returns a boolean[][]. Set cells to true to raise dots. gridToBraille(grid) converts it to a braille string (2 dot-columns per character).

API

interface Spinner {
  readonly frames: readonly string[];
  readonly interval: number;
