We feel build `--build-optimizer` is stable enough to not be experimental anymore.
This PR defaults `build-optimizer` when using Angular 5+ on a production build with `--aot`.
It can still be turned off with `--no-build-optimizer` (or `--build-optimizer=false`).
Fix#8050
This flag allows people who know what theyre doing to bundle the
server build together with all dependencies. It should only be
used when the whole rendering process is part of the main.ts
or one of its dependencies.
Fixes#7903.
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.
Adds following defaults to `.angular-cli.json` under `defaults`: `sourcemaps`, `baseHref`, `progress`, `poll`, `deleteOutputPath`, `preserveSymlinks`, `showCircularDependencies`.
They can be set via `ng set defaults.build.KEY = VALUE`.
Also removes `apps.0.showCircularDependencies`. This is not a breaking chance since it was only added in 1.3.0-beta.0.

This PR adds tsconfigs for each separate application:
- `src/tsconfig.app.json`: configuration for the Angular app.
- `src/tsconfig.spec.json`: configuration for the unit tests. Defaults to the Angular app config.
- `e2e/tsconfig.e2e.json`: configuration for the e2e tests.
There is an additional root-level `tsconfig.json` that is used for editor integration.
For Angular version 4 projects, these tsconfigs will use inheritance since it's available with TypeScript 2.1.
This is not a breaking change. Existing projects should not be affected.
Currently dev builds use `--output-hashing=none` by default.
This can cause image resources to be overwritten in dev if they have the same same.
This wasn't much of a problem before when only images in global CSS would be treated as resources, but now component css also does that.
Production builds are unaffected since they already use `--output-hashing=all`.
BREAKING CHANGE: dev builds will hash relative resources from CSS (images, etc).
