The ViewEngine message extraction generates a variety of legacy formats
for extracted message ids. These formats have a number of issues related
to whitespace handling and reliance upon information inside the original
HTML of a template. The new message format is more resilient to things
like whitespace changes, and can be generated directly from calls to
`$localize`, which allows messages in application code to have the same
id as identical messages in templates.
As a first step in migrating projects away from the legacy id format
for i18n messages, this commit updates newly generated projects to turn
off the legacy ids.
In the future the default will be flipped and this can be removed.
Eventually the legacy message id support will be removed altogether,
probably in sync with removal of ViewEngine.
Following feedback from the community, which showed a high number of users found it hard to work with the `no-any` lint rule and also the `sideEffects` package.json file. With DevRel we decided to remove both features when generating a strict workspace and/or application.
With this change we enable stricter type checking and optimization effective coding rules when using the `--strict` option.
Changes in schematics
- `ng-new`: A prompt for the `--strict` option was added. This option is a proxy and will be passed to the application and workspace schematics.
- `application`: A `package.json` was added in the `app` folder, to tell the bundlers whether the application is free from side-effect code. When `strict` is `true`. the `sideEffects` will be set `false`.
- `workspace` When `strict` is true, we add stricter TypeScript and Angular type-checking options.
Note: AIO is already using these strict TypeScript compiler settings. PR to enable `strictTemplates` https://github.com/angular/angular/pull/36391
