使用 Playwright 的视频录制功能,配合注入的光标覆盖层、自然的节奏和叙事流程,录制精美的 Web 应用演示视频。
每个演示都需经历三个阶段:探索 -> 排练 -> 录制。切勿直接跳至录制阶段。
在编写任何脚本之前,先探索目标页面,了解实际内容。
你无法为未见过的内容编写脚本。字段可能是 <input> 而非 <textarea>,下拉菜单可能是自定义组件而非 <select>,评论框可能支持 @mentions 或 #tags。假设会无声地破坏录制。
导航至流程中的每个页面,并转储其交互元素:
// Run this for each page in the flow BEFORE writing the demo script
const fields = await page.evaluate(() => {
const els = [];
document.querySelectorAll('input, select, textarea, button, [contenteditable]').forEach(el => {
if (el.offsetParent !== null) {
els.push({
tag: el.tagName,
type: el.type || '',
name: el.name || '',
placeholder: el.placeholder || '',
text: el.textContent?.trim().substring(0, 40) || '',
contentEditable: el.contentEditable === 'true',
role: el.getAttribute('role') || '',
});
}
});
return els;
});
console.log(JSON.stringify(fields, null, 2));
<select>、<input>、自定义下拉菜单还是组合框?value="0" 或 value="",看起来非空。使用 Array.from(el.options).map(o => ({ value: o.value, text: o.text }))。跳过文本包含"选择"或值为 "0" 的选项。@mentions、#tags、Markdown 或表情符号?检查占位符文本。required、*,并尝试提交空表单以查看验证错误。"Submit"、"Submit Request" 或 "Send"。input[type="number"] 映射到其列标题,而不是假设所有数字输入都表示相同含义。每个页面的字段映射,用于在脚本中编写正确的选择器。示例:
/purchase-requests/new:
- 预算代码: <select> (页面上的第一个下拉框,4个选项)
- 期望交付日期: <input type="date">
- 背景说明: <textarea> (非输入框)
- BOM表: 可内联编辑的单元格,包含 span.cursor-pointer -> input 模式
- 提交: <button> 文本="提交"
/purchase-requests/N (详情):
- 评论: <input placeholder="输入消息..."> 支持 @用户 和 #PR 标签
- 发送: <button> 文本="发送" (在输入内容前处于禁用状态)
在不录制的情况下运行所有步骤。验证每个选择器都能解析。
静默的选择器失败是演示录制中断的主要原因。排练可以在浪费录制之前发现它们。
使用 ensureVisible,一个记录日志并大声报错的包装器:
async function ensureVisible(page, locator, label) {
const el = typeof locator === 'string' ? page.locator(locator).first() : locator;
const visible = await el.isVisible().catch(() => false);
if (!visible) {
const msg = `REHEARSAL FAIL: "${label}" not found - selector: ${typeof locator === 'string' ? locator : '(locator object)'}`;
console.error(msg);
const found = await page.evaluate(() => {
return Array.from(document.querySelectorAll('button, input, select, textarea, a'))
.filter(el => el.offsetParent !== null)
.map(el => `${el.tagName}[${el.type || ''}] "${el.textContent?.trim().substring(0, 30)}"`)
.join('\n ');
});
console.error(' Visible elements:\n ' + found);
return false;
}
console.log(`REHEARSAL OK: "${label}"`);
return true;
}
const steps = [
{ label: 'Login email field', selector: '#email' },
{ label: 'Login submit', selector: 'button[type="submit"]' },
{ label: 'New Request button', selector: 'button:has-text("New Request")' },
{ label: 'Budget Code select', selector: 'select' },
{ label: 'Delivery date', selector: 'input[type="date"]:visible' },
{ label: 'Description field', selector: 'textarea:visible' },
{ label: 'Add Item button', selector: 'button:has-text("Add Item")' },
{ label: 'Submit button', selector: 'button:has-text("Submit")' },
];
let allOk = true;
for (const step of steps) {
if (!await ensureVisible(page, step.selector, step.label)) {
allOk = false;
}
}
if (!allOk) {
console.error('REHEARSAL FAILED - fix selectors before recording');
process.exit(1);
}
console.log('REHEARSAL PASSED - all selectors verified');
仅在探索和排练通过后,才创建录制。
将视频规划为一个故事。遵循用户指定的顺序,或使用此默认顺序:
4s3s2s1.5-2s3s25-40ms注入一个跟随鼠标移动的 SVG 箭头光标:
async function injectCursor(page) {
await page.evaluate(() => {
if (document.getElementById('demo-cursor')) return;
const cursor = document.createElement('div');
cursor.id = 'demo-cursor';
cursor.innerHTML = `<svg width="24" height="24" viewBox="0 0 24 24" fill="none" xmlns="http://www.w3.org/2000/svg">
<path d="M5 3L19 12L12 13L9 20L5 3Z" fill="white" stroke="black" stroke-width="1.5" stroke-linejoin="round"/>
</svg>`;
cursor.style.cssText = `
position: fixed; z-index: 999999; pointer-events: none;
width: 24px; height: 24px;
transition: left 0.1s, top 0.1s;
filter: drop-shadow(1px 1px 2px rgba(0,0,0,0.3));
`;
cursor.style.left = '0px';
cursor.style.top = '0px';
document.body.appendChild(cursor);
document.addEventListener('mousemove', (e) => {
cursor.style.left = e.clientX + 'px';
cursor.style.top = e.clientY + 'px';
});
});
}
每次页面导航后调用 injectCursor(page),因为覆盖层会在导航时被销毁。
切勿瞬移光标。在点击前移动到目标:
async function moveAndClick(page, locator, label, opts = {}) {
const { postClickDelay = 800, ...clickOpts } = opts;
const el = typeof locator === 'string' ? page.locator(locator).first() : locator;
const visible = await el.isVisible().catch(() => false);
if (!visible) {
console.error(`WARNING: moveAndClick skipped - "${label}" not visible`);
return false;
}
try {
await el.scrollIntoViewIfNeeded();
await page.waitForTimeout(300);
const box = await el.boundingBox();
if (box) {
await page.mouse.move(box.x + box.width / 2, box.y + box.height / 2, { steps: 10 });
await page.waitForTimeout(400);
}
await el.click(clickOpts);
} catch (e) {
console.error(`WARNING: moveAndClick failed on "${label}": ${e.message}`);
return false;
}
await page.waitForTimeout(postClickDelay);
return true;
}
每次调用都应包含描述性的 label 以便调试。
可见地输入,而非瞬间填充:
async function typeSlowly(page, locator, text, label, charDelay = 35) {
const el = typeof locator === 'string' ? page.locator(locator).first() : locator;
const visible = await el.isVisible().catch(() => false);
if (!visible) {
console.error(`WARNING: typeSlowly skipped - "${label}" not visible`);
return false;
}
await moveAndClick(page, el, label);
await el.fill('');
await el.pressSequentially(text, { delay: charDelay });
await page.waitForTimeout(500);
return true;
}
使用平滑滚动而非跳跃:
await page.evaluate(() => window.scrollTo({ top: 400, behavior: 'smooth' }));
await page.waitForTimeout(1500);
展示仪表盘或概览页面时,将光标移过关键元素:
async function panElements(page, selector, maxCount = 6) {
const elements = await page.locator(selector).all();
for (let i = 0; i < Math.min(elements.length, maxCount); i++) {
try {
const box = await elements[i].boundingBox();
if (box && box.y < 700) {
await page.mouse.move(box.x + box.width / 2, box.y + box.height / 2, { steps: 8 });
await page.waitForTimeout(600);
}
} catch (e) {
console.warn(`WARNING: panElements skipped element ${i} (selector: "${selector}"): ${e.message}`);
}
}
}
在视口底部注入一个字幕栏:
async function injectSubtitleBar(page) {
await page.evaluate(() => {
if (document.getElementById('demo-subtitle')) return;
const bar = document.createElement('div');
bar.id = 'demo-subtitle';
bar.style.cssText = `
position: fixed; bottom: 0; left: 0; right: 0; z-index: 999998;
text-align: center; padding: 12px 24px;
background: rgba(0, 0, 0, 0.75);
color: white; font-family: -apple-system, "Segoe UI", sans-serif;
font-size: 16px; font-weight: 500; letter-spacing: 0.3px;
transition: opacity 0.3s;
pointer-events: none;
`;
bar.textContent = '';
bar.style.opacity = '0';
document.body.appendChild(bar);
});
}
async function showSubtitle(page, text) {
await page.evaluate((t) => {
const bar = document.getElementById('demo-subtitle');
if (!bar) return;
if (t) {
bar.textContent = t;
bar.style.opacity = '1';
} else {
bar.style.opacity = '0';
}
}, text);
if (text) await page.waitForTimeout(800);
}
每次导航后,将 injectSubtitleBar(page) 与 injectCursor(page) 一起调用。
使用模式:
await showSubtitle(page, 'Step 1 - Logging in');
await showSubtitle(page, 'Step 2 - Dashboard overview');
await showSubtitle(page, '');
指南:
Step N - Action 格式以保持一致性。'use strict';
const { chromium } = require('playwright');
const path = require('path');
const fs = require('fs');
const BASE_URL = process.env.QA_BASE_URL || 'http://localhost:3000';
const VIDEO_DIR = path.join(__dirname, 'screenshots');
const OUTPUT_NAME = 'demo-FEATURE.webm';
const REHEARSAL = process.argv.includes('--rehearse');
// Paste injectCursor, injectSubtitleBar, showSubtitle, moveAndClick,
// typeSlowly, ensureVisible, and panElements here.
(async () => {
const browser = await chromium.launch({ headless: true });
if (REHEARSAL) {
const context = await browser.newContext({ viewport: { width: 1280, height: 720 } });
const page = await context.newPage();
// Navigate through the flow and run ensureVisible for each selector.
await browser.close();
return;
}
const context = await browser.newContext({
recordVideo: { dir: VIDEO_DIR, size: { width: 1280, height: 720 } },
viewport: { width: 1280, height: 720 }
});
const page = await context.newPage();
try {
await injectCursor(page);
await injectSubtitleBar(page);
await showSubtitle(page, 'Step 1 - Logging in');
// login actions
await page.goto(`${BASE_URL}/dashboard`);
await injectCursor(page);
await injectSubtitleBar(page);
await showSubtitle(page, 'Step 2 - Dashboard overview');
// pan dashboard
await showSubtitle(page, 'Step 3 - Main workflow');
// action sequence
await showSubtitle(page, 'Step 4 - Result');
// final reveal
await showSubtitle(page, '');
} catch (err) {
console.error('DEMO ERROR:', err.message);
} finally {
await context.close();
const video = page.video();
if (video) {
const src = await video.path();
const dest = path.join(VIDEO_DIR, OUTPUT_NAME);
try {
fs.copyFileSync(src, dest);
console.log('Video saved:', dest);
} catch (e) {
console.error('ERROR: Failed to copy video:', e.message);
console.error(' Source:', src);
console.error(' Destination:', dest);

}
await browser.close();
