Persistent disk build cache is now enabled by default. A number of options have been added to allow fine tuning of the cache.
The options can be configuration in `cli.cache` section in the `angular.json` as shown below.
- `enabled`: Configure whether disk caching is enabled. Defaults to `true`
- `environment`: Configure in which environment disk cache is enabled. Valid values `ci`, `local` or `all`. Defaults to: `local`
- `path`: cache base path. Defaults to `.angular/cache`
DEPRECATED: `NG_BUILD_CACHE` environment variable option will be removed in the next major version. Configure `cli.cache` in the workspace configuration instead.
BREAKING CHANGE: `NG_PERSISTENT_BUILD_CACHE` environment variable option no longer have effect. Configure `cli.cache` in the workspace configuration instead.
```json
{
"$schema": "./node_modules/@angular/cli/lib/config/schema.json",
"version": 1,
"cli": {
"cache": {
"enabled": true,
"path": ".custom-cache-path",
"environment": "all"
}
}
...
}
```
The `no-useless-escape` eslint rule has now been enabled which removes unneeded characters and complexity from string literals and regular expressions. All files that were in violation of this rule have also been corrected.
With this change we allow unset a config value to be a JSON.
Example, `ng config -g schematics {}` will remove the entire `schematics` section from the configuration.
With this change we allow unset a config value when the provided value is `undefined`.
Example, `ng config -g schematics undefined` will remove the entire `schematics` section from the configuration.
BREAKING CHANGE:
Removed deprecated `typescriptMismatch` warning option. Users will be migrated off this option automatically. Users wishing to disable TypeScript version checks should use the Angular compiler option `disableTypeScriptVersionCheck`, see https://angular.io/guide/angular-compiler-options#disabletypescriptversioncheck for more information.
Some commands (like schematics) need to have custom reporting for
analytics. Schematics and Architect commands need to verify if the
schematic/architect builder run is in the safelist, for example.
Angular 5.0+ has a full peer dependencies setup (with 6.0+ also having a configurable runtime error check) to ensure that an appropriate version of typescript is available for compilation. Angular CLI 8.0+ does not support Angular versions prior to these and therefore the warning is redundant. For the case where the developer wishes to use an unsupported TypeScript version, the developer would need to adjust two similar but differently name settings in two different configuration files.
