This simple change seems to work for me:
```
const ignored = [
'**/.*',
'node_modules'
]
```
I believe the regex is used here to try and work on windows as well. So, I wasted a bunch of time trying to figure out how to use a regex and/or the `path` module to ignore the parent directories until I noticed the following:
> glob patterns are not filepaths. They are a type of regular language that is converted to a JavaScript regular expression. Thus, when forward slashes are defined in a glob pattern, the resulting regular expression will match windows or POSIX path separators just fine.
this is from the [anymatch](https://github.com/micromatch/anymatch) documentation which is what webpack uses accoring to this:
https://webpack.js.org/configuration/watch/#watchoptions-ignored
I've verified this glob pattern solves the problem in my environment, can someone test and verify that this works on windows?

Adds the possibility for users to copy files inside of `exportPathMap`. This allows for adding `robots.txt` `sitemap.xml` etc. another use case is for https://github.com/hanford/next-offline, currently it's manually reading the buildId in `exportPathMap`.
To allow users to do this we'll introduce a new parameter holding an object with the following keys:
- `dev` - `true` when `exportPathMap` is being called in development. `false` when running `next export`. In development `exportPathMap` is used to define routes and behavior like copying files is not required.
- `dir` - Absolute path to the project directory
- `outDir` - Absolute path to the `out` directory (configurable with `-o` or `--outdir`). When `dev` is `true` the value of `outDir` will be `null`.
- `distDir` - Absolute path to the `.next` directory (configurable using the `distDir` config key)
- `buildId` - The buildId the export is running for
Example usage:
```js
// next.config.js
const fs = require('fs')
const {join} = require('path')
const {promisify} = require('util')
const copyFile = promisify(fs.copyFile)
module.exports = {
exportPathMap: async function (defaultPathMap, {dev, dir, outDir, distDir, buildId}) {
if(dev) {
return defaultPathMap
}
// This will copy robots.txt from your project root into the out directory
await copyFile(join(dir, 'robots.txt'), join(outDir, 'robots.txt'))
return defaultPathMap
}
}
```
There's an edge case @timothyis is running into, this will show exactly what files are missing.
I currently can't reproduce, so this is a first step at providing better error messages
The current canary version shows the following warning in development mode:
```log
Warning: Each child in an array or iterator should have a unique "key" prop. See https://fb.me/react-warning-keys for more information.

```
This PR adds proper keys to the devFiles on the server.

Failing tests are expected as `@zeit/next-css` has to be updated/released first.
This implements rendering of `.css` chunks. Effectively removing the custom document requirement when adding next-css/sass/less/stylus.

This PR fixes#4615
From the issue :
> One thing we might consider is merging and showing a warning for keys not defined in exportPathMap
The behaviour after this PR is the following :
```js
// next.config.js
module.exports = {
exportPathMap: () => ({
'/': { page: '/', query: { a: 'blue' } }
})
}
```
| url called | `ctx.query` | warning ? |
|-|-|-|
| `/` | `{ a: 'blue' }` | |
| `/?a=red` | `{ a: 'blue' }` | |
| `/?b=green` | `{ a: 'blue', b: 'green' }` | `... parameter 'b' missing in exportPathMap` |
Is that the expected behaviour ? If not, I'll update the PR to shape the expected behavior.
I can't use a functional component with `_document.js`.
[is-react](https://www.npmjs.com/package/is-react) can be used for another potential implementation of the warning logic, but maybe relying on `React.createElement()` internal checks is enough.
A follow-up to #4604: the dot in the regexp was not escaped as intended. By default `*` matches greedily, so the results are the same, but the new regexp should be more clear. Sorry for the mistake.
The prepares for next-server.
I also took this as an opportunity to get all build directory paths from a single location, as they were previously scattered across webpack/babel plugins and loaders.
Fixes#4603.
Tests explain it the best:
```js
describe('development mode (no chunkhash)', () => {
it('should strip the extension from the filename', () => {
const filename = 'foo_bar_0123456789abcdef.js'
expect(getChunkNameFromFilename(filename, true)).toBe('foo_bar_0123456789abcdef')
})
it('should only strip the extension even if there\'s a hyphen in the name', () => {
const filename = 'foo-bar-0123456789abcdef.js'
expect(getChunkNameFromFilename(filename, true)).toBe('foo-bar-0123456789abcdef')
})
})
describe('production mode (with chunkhash)', () => {
it('should strip the hash from the filename', () => {
const filename = 'foo_bar_0123456789abcdef-0123456789abcdef.js'
expect(getChunkNameFromFilename(filename, false)).toBe('foo_bar_0123456789abcdef')
})
it('should only strip the part after the last hyphen in the filename', () => {
const filename = 'foo-bar-0123456789abcdef-0123456789abcdef.js'
expect(getChunkNameFromFilename(filename, false)).toBe('foo-bar-0123456789abcdef')
})
})
```
This fixes a missed bug introduced in #4510.
Because the regexp was `/-[^-]*/` and not `/-[^-]*$/`, a wrong part of the filename was being removed:
```
bad:
'foo-bar-0123456789abcdef-0123456789abcdef.js' -> 'foo-0123456789abcdef-0123456789abcdef.js'
good:
'foo-bar-0123456789abcdef-0123456789abcdef.js' -> 'foo-bar-0123456789abcdef'
```
By a stroke of luck this didn't affect the existing dynamically generated chunks. To prevent regression I've added unit tests for the function that generates the name.
Btw. in the original issue (#4433) I used the right regexp, I just used the wrong regexp in #4510.
cc @timneutkens
Fixes one of the problems described in #4433.
The old regexp was removing everything after a hyphen, so with a chunk name like so:
```
chunks/path-to-a-file-[hash].js
```
the saved chunk name was
```
chunks/path
```
This caused problems, because webpack by default changes `/` to `-` in chunk names generated e.g. by ``import(`foo/${bar}`)``.
After this change the chunk name will be
```
chunks/path-to-a-file
```
Since `_app.js` is used on every page it makes sense to move it's dependencies to the `commons.js` so that if you require a dependency in `_app.js` and in one of your pages it is not included twice in your bundles.
This PR modifies the `CommonsChunkPlugin` to move every module that is used in `_app.js` and at least in one other bundle.
