通过使用process.nextTick()保证了apiCall()的回调永远能在执行完调用者其它的代码以后且在事件循环继续之前被执行。为了实现这一点, JS 调用栈可以被释放,然后立刻执行给出的回调,这个回调可以递归调用process.nextTick()而不会得到RangeError: Maximum call stack size exceeded from v8错误。 这个设计理念可以导致一...

ctx.query = { next: '/login' }; request.fresh检查请求缓存是否“新鲜”,也就是内容没有改变。此方法用于 If-None-Match / ETag,和 If-Modified-Since 和Last-Modified 之间的缓存协商。 在设置一个或多个这些响应头后应该引用它。// 新鲜度检查需要状态20x或304 ctx.status = 200; ctx.set('ETag',...

next(value); if (data.done) { return; } else { data.value.then(x => { value = x; loop(); }) } } loop(); } This function takes any generator as an argument, and keeps calling next() on it as long as there are values to yield. In this case, the yielded values are ...

The state of glPixelStore is now properly cleaned after texture updates to avoid glTexSubImage2D calls made on the same gl context acting differently at random (#5730) ...Add new stuff here... 5.3.0 ✨ Features and improvements Added getBounds to GeoJSON source to allow getting the bound...
As part of the new app router structure, Next lays out a tree of components that includes the following loop (rendering a hypothetical /path/subpath request): - Root Layout - OuterLayoutRouter - TemplateContext.Provider key="path" - Root Template - InnerLayoutRouter - Path Layout - Outer...
