* Move type to image component
* Add types/global.d.ts to excludes too
* Undo global exclude as it's using internally
* Don't add root imports for module augmentations
Currently, we print warnings during `next dev` for every render of `next/image`, which can quickly fill the console making it really unfriendly to developers trying to read the logs.
This PR changes the behavior so that each unique warning prints at most once.

In PR #26968, we added Set of loaded images that was removed in #33474 erroneously.
We still need to track loaded images since we can't rely on `img.complete`, especially if the parent uses `react-virtualized`.
Tested on https://nextjs.org/showcase
* Added 'rootEl' oprional property to next/Image component resembling 'root' option of the Intersection Observer API
* changed 'rootEl' to 'lazyBoundary' and its type as well
* added test, fixed initial root detection
* Update test/integration/image-component/default/test/index.test.js

* prop names changed
* added 'lazyroot' prop to the documentation
* removed unused import
* Apply suggestions from code review
* Update docs with lazyRoot added in 12.0.9

The image prop `onLoadingComplete()` was unexpectedly called multiple times because it uses a [callback ref](https://reactjs.org/docs/refs-and-the-dom.html#callback-refs).
This could lead to an infinite loop if `onLoadingComplete()` calls `setState()` as demonstrated in the updated test.
The solution is to handle refs with `useRef()` and `useEffect` so `onLoadingComplete()` is called at most once per component instance.

This PR is a follow up to PR #32623 to fix the remaining blur styles.
These are unlikely to be overridden by the user but this PR is necessary to make `placeholder=empty` (default behavior) and `placeholder=blur` end up with the same inline styles on the loaded image.

Some libraries, like react-slick, render their content to a detached element before attaching it to the dom. If the content of such libraries is Image components, they will report warnings because the display/position properties are undefined. This PR squelch the warnings for such cases.
## Bug
Fixes#31892
react 18: requires camelcase for those props
```
Warning: Invalid DOM property `imagesrcset`. Did you mean `imageSrcSet`
```
react 17: requires lowercase for those props
```
Warning: React does not recognize the `imageSrcSet` prop on a DOM element.

### Utils
* Add command `yarn next-react-18 test/integration/any-react-18-app/`
* Add util `withReact18`
```js
const withReact18 = require('../../react-18/test/with-react-18')
module.exports = withReact18({
experimental: {
concurrentFeatures: true,
},
})

Some users reported false hits when using complex loaders that implement Art Direction.
We can relax the warnings so that query string params named width should not warn.
As a follow up to #30041 which changed `<div>` to `<span>`, this PR makes sure that unexpected styles are not applied to the image wrapper or sizer spans.
For example: `.content span {}` would apply to all spans and incorrectly style the image wrapper.
This PR adds [`all: initial`](https://developer.mozilla.org/en-US/docs/Web/CSS/all) to effectively reset the span styles.
This type was added in PR #28269 but doesn't need to be public and was causing conflicts with `@types/react@17`.
We currently use `@types/react@16` so ideally we should upgrade to `@types/react@17` and then remove the `ts-ignore`.
Fixes#28647
This PR does a few things:
- Moves `<noscript>` usage below the blur image since so that the `<noscript>` image renders on top of the blur image
- Remove the `isVisible` check for `<noscript>` since we can't rely on client-side JS
- Add `loading=lazy` to the `<noscript>` image to take advantage of native lazy loading (can't rely on JS lazy loading)
Fixes#28251
This PR resurrects #23622 which has not been updated in a while. Makes the `Image` component handle `blob:` object urls.

This PR adds a single data attribute to the image element generated by the image component `data-nimg`) which just serves to signal that this image element is from the component. Currently it's hard to quickly/programmatically determine with certainty whether an image is from the component or not, so this change should make it easier for us to diagnose and improve performance issues related to the image component.
We've never supported the `style` prop as seen in the docs https://nextjs.org/docs/api-reference/next/image#other-props
TS users already get a build error but JS users were left in the dark.
This PR adds a warning so its clear during `next dev`.
This PR adds `lazyBoundary` prop on Image Component.
This feature is to load the images earlier.
I'm not good at English. So, I couldn't explain enough in the documentation what `lazyBoundary` is.

We shouldn't be setting `placeholder=blur` styles when JS is disabled because we'll have no way to know when the image is loaded and it will be stuck in blur permanently as mentioned in [this comment](https://github.com/vercel/next.js/pull/19052#issuecomment-882886068).
This PR avoids blur styles on the `<noscript>` version of the image.
Since we are no longer accepting new built-in loaders, users may wish to use a different cloud provider.
So this PR renames `dangerously-unoptimized` to `custom` to handle this case as well as the intention of `next export`.
If the user doesn't add a `loader` prop, we throw an error.
If the user adds a `loader` prop but it doesn't return the width, we print a warning.

### Description
This changes the strict TS types to a looser implementation such that the user can pass `src` without TS errors.
### Pros vs Cons
- **Pros**: better support for wrapping `next/image` so that TS won't report false errors
- **Cons**: using `src: string` without `blurDataURL` will no longer show TS errors and instead fail with a runtime error
### Issues
- Fixes#26892
- Related to #26991
### Description
This changes the strict TS types to a looser implementation such that the user can always pass `width` and `height` (even when `layout=fill`) without TS errors.
### Pros vs Cons
- **Pros**: better support for wrapping `next/image` so that TS won't report false errors with `layout=fill`
- **Cons**: omitting width/height when using other `layout` will no longer show TS errors and instead fail with a runtime error
### Issues
- Fixes#26531
- Fixes#25440
fixes#19074
This change disables image lazy-loading when both of the following are true:
1) A image is being rendered following a client-side page transition
2) The image has been previously loaded during this session.
Before this change, all images with lazy-loading enabled have a visible flicker during client-side page transitions, even though they're already loaded.
With this change, there's are two performance risks:
1) There's a chance that some offscreen images will have lazy-loading disabled unnecessarily because they were previously loaded. I think the performance hit here is pretty negligible and the situation is unlikely to come up very often.
2) There's a chance a different-sized version of the image will be selected by the browser, but lazy-loading will be disabled anyway. This seems even more unlikely to me, and anyway the performance hit from a stray un-lazy-loaded image (on a client-side transition) is very minor.
In both cases, I think the performance risk is outweighed by the UX improvement of getting rid of the image flicker on page transition.
If the `Image` src url had existing query params, the imgix loader would simply append another query string with `?` causing both query strings to break.
This PR adds a way to safely merge query strings if needed using [URLSearchParams](https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams).
