How streaming works in Next.js, explained with a simple example

[00:00] So, in Next.js, most of the hard works [00:02] have been actually abstracted away. So, [00:05] streaming actually means by concept, it [00:07] means sending the page in pieces instead [00:09] of all at once. So, imagine a page where [00:13] the header loads fast, but the comments [00:16] take long longer. There is a header [00:17] section and a comment section. The [00:19] header can be loaded faster and the [00:21] comment section can be loaded later. So, [00:23] with streaming, Next.js sends the header [00:25] immediately so the user can see [00:27] something so that we get the FCP like [00:30] fast contentful paint. And the comments [00:32] appear later when they are ready. So, [00:34] the page feels faster even though [00:36] everything isn't finished. So, it's like [00:37] the information is actually coming part [00:40] by part, piece by piece. That's it.
