The TypeScript `isolatedModules` option is now enabled for all TypeScript
code within the repository. As a result, all packages will now be built
with the option enabled. This does not affect projects created with the CLI
and is only related to the building of the actual Angular CLI code.
The `isolatedModules` option ensures that code can be emitted without the
TypeScript typechecker and allows tools other than TypeScript to potentially
be used. Code was updated to correct all errors after the option was enabled.
Additionally, some early code fixes were done to add function and accessor
return types to prepare for future `isolatedDeclarations` usage. More changes
would be needed to consider turning on `isolatedDeclarations`, however.
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)
The source code for the builders within the `@angular-devkit/build-webpack` package have been moved
into a `builders` subdirectory to more closely align with the structure of the builders in the
`@angular-devkit/build-angular` package. An initial `package.json` exports field definition has also
been added that currently continues to allow deep imports.
`compileComponents` is not necessary when using the CLI (as the templates are inlined) and just adds boilerplate code. So we can remove it from the test schematic and make it independent from `async/await` (only place we would have it in the CLI generated code, and in most Angular apps).
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
When performing a release via the dev-infra `ng-dev` tooling, the release
builds for the packages that will be published are now performed using bazel.
Prior to this, the release builds were performed using a custom build script
that programmatically invoked TypeScript APIs. The Bazel build and discovery
process for the releasable packages is performed by a script that is based on
the scripts from components and framework repositories. Several small modifications
were performed to match the behavior and structure of the cli repository:
* Use of `packages` as the source root in the bazel query
* Use of `pkg_npm` rule in the bazel query
* Partial transition to native Node.js `fs` APIs instead of `shelljs`
* Directory creation per package when copying output (supports multiple package scopes)
* Copying of archives (tgz) for each package
The snapshot and local build capabilities are not modified as part of this change
but will be merged in a followup as part of a larger transition to use bazel
throughout the package build process.
This commit removes the usage of environment files and `fileReplacements` in new application projects. Previously, the environment files was used to distinguish between a prod build to invoke `enableProdMode`. The `enableProdMode` however needed only for the case of JIT mode in production mode, which is a rare case as JIT mode is recommanded to be used in production.
In the CLI, calling `enableProdMode` is not needed as `ngDevMode` it's set using the minifier.
With this change we reduce the reliance on the TypeScript target compiler option to output a certain ECMA version. Instead we now use the browsers that are configured in the Browserslist configuration to determine which ECMA features and version are needed. This is done by passing the transpiled TypeScript to Babel preset-env.
**Note about useDefineForClassFields**: while setting this to `false` will output JavaScript which is not spec compliant, this is needed because TypeScript introduced class fields many years before it was ratified in TC39. The latest version of the spec have a different runtime behavior to TypeScript’s implementation but the same syntax. Therefore, we opt-out from using upcoming ECMA runtime behavior to better support the ECO system and libraries that depend on the non spec compliant output. One of biggest case is usages of the deprecated `@Effect` decorator by NGRX and potentially other existing code as well which otherwise would cause runtime failures. Dropping `useDefineForClassFields` will be considered in a future major releases. For more information see: https://github.com/microsoft/TypeScript/issues/45995.
BREAKING CHANGE: Internally the Angular CLI now always set the TypeScript `target` to `ES2022` and `useDefineForClassFields` to `false` unless the target is set to `ES2022` or later in the TypeScript configuration. To control ECMA version and features use the Browerslist configuration.
