Avoid copying directly directories, also which this change we cache `fs.existsSync` to optimize copying when a lot of file are being copied to the same destination.
Closes: #15816
In applications that make heavy use of lazy routes and ES2015 libraries, this option can improve bundle sizes. It might also break your bundles in ways we don't understand fully, so please test and report any problems you find.
NOTE: the following are known problems with experimentalRollupPass
- vendorChunk, commonChunk, namedChunks: these won't work, because by the time webpack sees the chunks, the context of where they came from is lost.
- webWorkerTsConfig: workers must be imported via a root relative path (e.g.`app/search/search.worker`) instead of a relative path (`/search.worker`) because of the same reason as above.
- loadChildren string syntax: doesn't work because rollup cannot follow the imports.
Version 10.13.0 was the first version of 10.x that was considered LTS. This also provides an improved performance baseline as well as access to newer Node.js APIs and Javascript language features which the Angular CLI will now be able to leverage.
* feat(@angular-devkit/core): update schema to support new i18n options
"projects": {
"my-app": {
"projectType": "application",
"schematics": {},
"root": "",
"i18n": {
"sourceLocale": "en-US",
"locales": {
"fr": "src/locale/messages.fr.xlf"
}
},
"sourceRoot": "src",
...
}
}
* feat(@angular-devkit/build-angular): add new i18n options to browser and server builders
With this change we add `translateLocales` as new options for i18n in browser and server builders.
We also deprecate the following options;
* i18nLocale
* i18nFormat
* i18nFile
* feat(@angular-devkit/build-angular): deprecate `i18nFormat` and `i18nLocale` options of `extract-i18n` builder
Option `i18nFormat` has been deprecated in favor of `format` and `i18nLocale` option has been deprecated in favor of the `sourceLocale` sub option of the `i18n` project level option.
* feat(@angular/cli): add alias of `i18n-extract` for `x18n` command
* refactor: rename `translateLocales` to `localize`
This is currently only supported when performing a differential loading build (no watch mode). This will eventually be expanded to cover watch mode and non-differential loading builds.
This transformer can cause size regressions when it introduces `tslib` imports across independent chunks.
It should be deprecated because tslib adoption has become more ubiquitous.
Should also speed up Build Optimizer processing time because there's one less thing to do.
Closes https://github.com/angular/angular-cli/issues/15401 without adding the warning, because some libraries like zone.js should inline the helpers.
PR #15607 removed the `_pure_getters` optimization as it no longer has effect on the framework size.
But it does have an effect on third party library.
For example a simple project using `@ng-bootstrap/ng-bootstrap` goes from `444K` uncompressed with CLI `9.0.0-next.5` to `488K` with CLI `9.0.0-next.6` which introduced the removal.
When a `__decorator` expression has no `__metadata` call, example:
```js
__decorate([
ContentChild('heading', { read: ElementRef, static: true })
], FooBarComponent.prototype, "buttons", void 0);
```
A `Cannot read property 'kind' of undefined` error will be thrown.
Closes: #15703
