Updates for all angular.io links to the new angular.dev domain. Additionally, adjustment to new resources where the equivalent does not exist on the new site (e.g. Tour of Heroes tutorial)
G3 is now using RXJS version 7 which makes it possible for the CLI to also be updated to RXJS 7.
NB: this change does not remove all usages of the deprecated APIs.
Closes#24371
This reduces the number of imports for the Node.js file host classes. The `fs` default
import was only used in one place and named imports were already in use for `node:fs`
which allowed the one use to be converted to a named import. The type only import for
`chokidar` was also only used in one type annotation and was moved to the type
annotation directly.
Prepares the `@angular-devkit/core` package for the eventual change of enabling the
TypeScript `useUnknownInCatchVariables` option. This option provides additional
code safety by ensuring that the catch clause variable is the proper type before
attempting to access its properties. Similar changes will be needed in the other
packages in the repository prior to enabling `useUnknownInCatchVariables`.
Node.js v12 will become EOL on 2022-04-30. As a result, Angular CLI v14 will no longer support Node.js v12.
BREAKING CHANGE:
Support for Node.js v12 has been removed as it will become EOL on 2022-04-30. Please use Node.js v14.15 or later.
The `NodeJsSyncHost`/`NodeJsAsyncHost` classes' `delete` method uses `fs.rmdirSync`/`fs.rmdir` to delete directories. However, Node.js v16's `fs.rmdirSync`/`fs.rmdir` will now throw an `ENOENT` error if the path does not exist. `fs.rmSync`/`fs.rm` is now the preferred option when using Node.js v16 but since this function is not available on Node.js v12 both are tried with `fs.rmSync`/`fs.rm` given preference.
Once Node.js 12 support is dropped, the `delete` method could potentially be refactored to avoid the `isDirectory` check and only use `fs.rmSync`/`fs.rm` which supports both files and directories.
All TypeScript files have been updated to pass the new eslint-based linting checks. eslint compatible disabling comments have also been added in place of the previous tslint comments.
This fixes a few error surfaced by adding `"strict": true` to `tsconfig.json`.
* `_callFs(fs.readdir, /* ... */)` needs explicit types because `fs.readdir` has a few overloads, which was confusing type inference.
* `TempScopedNodeJsSyncHost._sync` is an uninitialized property, but it was already being checked for `undefined`, so I simply made its type optional.
* `TempScopedNodeJsSyncHost.files` had an incorrect type assertion, but was otherwise correct. I just removed the assertion and let type inference do the trick.
It is unused within our code, as webpack will do the file watching.
This removes 1.4 MB from the download size of the package.

BREAKING CHANGE:
Users who rely on angular-devkit/core to do the file watching must add chokidar to their devDependencies.
