This removes the peer dep on `webpack` from `react-dev-overlay`, as it is for types only.
This makes the peer dep on `webpack` optional for `react-refresh-utils`, as you can provide webpack via the constructor (how Next.js does).
This picks up on the inlining work in https://github.com/vercel/next.js/pull/20598 to also include webpack loader inlining optimizations.
This includes:
* The dependencies of sass-loader
* resolve-url-loader
And for added benefit:
* babel-plugin-transform-define
* babel-plugin-transform-react-remove-prop-types
style-loader and css-loader didn't inline easily. Perhaps we can come back to these ones.

> According to https://nextjs.org/docs/basic-features/image-optimization#caching Next.js populates a cache dir when using the new <Image /> component. This is not the case when using SVG files. This results in a performance penalty.
I created a function for writing images to cache directory (`wrirteToCacheDir`) and it is called for all images.
However, vector and animated images are not optimized before writing them to cache dir

Hello friends
Ran into this bug on our production site, prerenderManifest stores revalidation info for the index as `"/": { .. }`, but the code tries to access this information as `"/index"`.
This leads to our index page always having s-max-age: 1
This pull request adds `future.strictPostcssConfiguration`, allowing users to opt-into the more strict PostCSS configuration loading.
This stricter PostCSS configuration loading ensures that CSS can be cached across builds.
Fixes#16864
The `router` can be missing in a test environment when trying to render a `Link` component. This PR bails out of `router.prefetch()` when `router` is missing.
The alternative is for users to mock `next/link` or to mock the `router` and wrap their test components.
Please let me know any feedback.
This updates the error shown when a path doesn't match the dynamic route in `getStaticPaths` to not include the `locale` since this isn't considered when matching against the dynamic route.
This ensures rewrites to API routes with i18n enabled handles as an API route correctly. This also adds tests for API routes in the i18n test suite
Fixes: https://github.com/vercel/next.js/issues/20725
This is a #19325 reconfigured to support a loader passed in via a `loader` prop on the Image component, rather than using a config-based approach.
The idea is that applications wanting to use a custom loader will create a wrapper element for the image component that incorporates that loader. See a simple example of this pattern in the integration tests.
This solution is similar to the one prototyped by @ricokahler in #20213 and described at https://github.com/vercel/next.js/issues/18606#issuecomment-720149156

Closes#19325Fixes#18606
Currently pages with `notFound: false` from `getServerSideProps` behave the same as `notFound: true`, i.e. just having the key is enough to result in a 404. This fixes the check in render.tsx and adds tests for it.
This pull request correctly assigns boolean attributes for `<script />` to match the element as it is created by a server-side render.
Prior to this pull request, we'd double-execute `<script>` tags with the `async`, `defer`, or `nomodule` property.

**What's the problem this PR addresses?**
`@next/mdx` adds the webpack loader `@mdx-js/loader` without resolving it to an absolute path
Depends on https://github.com/vercel/next.js/pull/17606
**How did you fix it?**
`require.resolve` the webpack loader before adding it
This PR is a small follow-up to #14705. It saves Next.js users from falling into a [pretty nasty trap](https://github.com/nodejs/node/issues/36620) in which I ended up last Friday. It took more than two days to investigate what was going on, so I hope I'm the last person who’s doing it 😅
Next.js-specific MWE: https://github.com/kachkaev/hanging-response-in-next-via-redirect-plus-compression (needs to be ran locally using Node 14.0.0+).
> <img width="521" alt="Screenshot 2020-12-24 at 20 50 00" src="https://user-images.githubusercontent.com/608862/103105989-a9b8dc00-4629-11eb-9be3-5108755604bf.png">
To reproduce the bug I’m fixing:
1. Pick a large http body size (64 or 128 KB)
1. Check _Call res.end() after res.redirect() in /api/redirect_
1. Navigate to a heavy page or an api handler via redirect
1. Observe that the http response is never finished.
If you set `compress` to `false` in `next.config.js` or pick a small payload size (< `zlib.Z_DEFAULT_CHUNK` after compression), the bug will not be observed. This is explained by the use of `res.on("drain", ...)` [by the `compression` package](3fea81d0ea/index.js (L193-L218)). The package itself is not the reason for an issue though, it seems to be in the Node’s built-in `http` package.
I’m happy to provide more info or GitHub CI to the MWE if needed. I was also thinking of adding some Next.js-specific testing, but could not come up with a compact and clear test plan. Happy to do this if there are any ideas.

Follow-up to https://github.com/vercel/next.js/pull/20628 this ensures `isReady` is not initially true when the query isn't present but the page is an automatically statically optimized dynamic route
Currently there is no way to add multiple meta tags with the same name attribute to the head of a page. This PR modifies the Head component to allow multiple meta tags with the same name if they have unique keys.
This is important for integrating with certain services like Google Scholar and Swiftype.
Fixes#10183
This PR fixes a bug where `next/babel` would accidentally enable development transforms for a production build (`next build`).
This is tested by the two updated unit tests (which removed a workaround for this bug, and one now properly enables dev transforms).
