- remove tether import in .angular-cli.json
- add umd version popper.js import in .angular-cli.json instead of tether
Closes#7584
This adds the new parameter `missingTranslation` for AoT that was added in angular/angular/pull/15987 and that lets you define the MissingTranslationStrategy
ECMAScript 2017 was released at the end of June. Standard library support for ES 2017 is around in TypeScript for quite a while now. Even `typescript@~2.0.0` which is used by the Angular 2 template supports a subset of ES 2017. Hence, it seems reasonable to update to the latest standard library version.
- change the URL for the API search
- use google search when --search option is true, since angular.io doesn't have a search page anymore
- improve the help and doc of the doc command
Followup to #6881
Allow controlling chunk naming via the `--named-chunks` flag, which can be set on `.angular-cli.json` as well.
Defaults to true in development, false in production.
Adds the new flag `--build-optimizer` (`--bo`), usable only with `--aot` (or `--prod` since it auto enables `--aot`).
This feature is experimental, and may not work correctly on your project. Should it work, total bundle size should go down. Savings are heavily dependent on the project.
See https://github.com/angular/devkit/tree/master/packages/angular_devkit/build_optimizer for details about all the optimizations applied.
Usage: `ng build --prod --build-optimizer`. Disabling the vendor chunk has been shown to improve total savings, and is done automatically when `--bo` is specified unless `--vendor-chunk` has a value.
Please let us know if using `--build-optimizer` breaks your project so we can improve it further. Repos are very welcome.
Circular dependencies, like `app.module.ts` importing `app.component.ts` which in turn imports `app.module.ts`, now display a warning during builds:
```

```
It is important to detect and eliminate circular dependencies because leaving them in might lead to `Maximum call stack size exceeded` errors, or imports being `undefined` at runtime.
To remove these warnings from your project you can factor out the circular dependency into a separate module.
For instance, if module A imports `foo` from module B, and module B imports `bar` from module A, it is enough to extract `foo` into module C.
You can turn off these warnings by running ng set apps.0.hideCircularDependencyWarnings=true. This will add the "hideCircularDependencyWarnings": true value to your .angular-cli.json and disable the warnings.
Fix#6309Fix#6739
If there is a need to define multiple entries or otherwise more complex configuration a js file can be used to configure the proxy. These changes document how to do so.
* for several options that are saved in .angular-cli.json, I've added an explanation of what setting in the json file controls that options.
* added an explanation about what --dry-run will output.
* added possible values for --style option
* added respective documentation in the command
* also added less, sass and styl(stylus) as possible style extensions
The motivation for this change is that sometimes people would want to change some of the settings set by the cli durig ng new, that they might have not known or cared about, for example, prefix.
* add an explanation about what --dry-run will output
* add an explanation about what --lint-fix will do
* add an explanation about how to set default to use lint always
* add an explanation about what --verbose will do
Two new flags are added to `ng serve`:
- `--public-host` (aliased by `--live-reload-client): Specify the URL that the browser client will use.
- `--disable-host-check`: Don't verify connected clients are part of allowed hosts.
Setting `--disable-host-check` will output a warning:
```
WARNING Running a server with --disable-host-check is a security risk. See https://medium.com/webpack/webpack-dev-server-middleware-security-issues-1489d950874a for more information.
```
See #6070 for more context about this change.
