常见的想当然
Puppeteer's device and network presets are properties on the default export, device descriptors use mobile/touch keys, and network throughput values are kilobits per second.
这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。
契约
- Puppeteer 24.4.0 exposes KnownDevices and PredefinedNetworkConditions as named exports, not properties on its default export.
- KnownDevices has separate iPhone 15 portrait and landscape descriptors whose viewport uses isMobile, hasTouch, and isLandscape.
- PredefinedNetworkConditions['Fast 3G'] records download/upload throughput in bytes per second and latency in milliseconds.
- Copying a network preset before customization leaves the process-wide preset unchanged.
