### Build

Uses the Angular compiler (`ngc`) in partial-compilation mode so published
JavaScript and declarations contain the Angular metadata required by both JIT
and AOT consumers.
Built with `ng-packagr` via the Angular CLI (`@angular/build:ng-packagr`
builder): partial-compilation FESM bundles plus type declarations for the
main entry and each plugin secondary entry point. Plugin entry points use
named exports because the Angular Package Format strips `export default`
from entry points (e.g. `import { math, Math } from '@comark/angular/plugins/math'`).

Use one publish-directory setting.

npm.publishPath makes release-it publish from dist, while packages/comark-angular/package.json also sets publishConfig.directory to dist. ng-packagr 22 copies that setting into dist/package.json. The release command can therefore target dist/dist; publishing from dist also leaves the generated comark: "workspace:*" dependency outside its workspace resolution context. Remove publishPath and publish from the package root using its publishConfig.directory setting. (github.com)

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In `@packages/comark-angular/.release-it.json` at line 14, Remove the
npm.publishPath setting from the release-it configuration so publishing starts
from the package root and uses the existing publishConfig.directory setting.
Keep the package’s publishConfig.directory unchanged.

site:angular.dev tools libraries creating libraries application Angular version same or newer than dependent libraries partial compilation

💡 Result:

<search_synthesis>
When developing and consuming Angular libraries, the Angular version used to build an application must always be the same as or newer than the version used to build any of its dependent libraries [1]. For instance, an application using Angular 15 can consume a library built with Angular 14, but an application using Angular 14 cannot reliably consume a library built with Angular 15 [1]. Partial Compilation and Compatibility To ensure libraries can be consumed across different Angular versions, they should be distributed using the partial-Ivy compilation format [1][2]. 1. Partial-Ivy (&quot;compilationMode&quot;: &quot;partial&quot;): This is the recommended mode for publishing libraries to npm [1]. It produces a stable, intermediate format that is not tied to a specific Angular runtime version [2]. During the application build process, the Angular CLI takes this partial code and compiles it into fully compiled code using the application&#39;s specific Angular version [1][2]. This ensures that the application and all its libraries effectively use a single, consistent version of the Angular compiler [1]. 2. Full-Ivy (&quot;compilationMode&quot;: &quot;full&quot;): This mode generates fully AOT-compiled code tied to the specific version of Angular used at the time of compilation [3][2]. Because the generated Ivy instructions are not part of the public API and may change between patch versions, full-Ivy libraries are generally not safe to publish to npm [1]. This mode is only appropriate for mono-repository environments where the library and application are built from source using the exact same version of Angular [1][3]. Best Practices for Versioning To maintain compatibility and manage updates effectively, follow these practices: - Use ng update to keep library dependencies current [4]. If libraries have interdependencies, updating them in the correct order is critical [4]. - Provide update schematics for your libraries if you introduce breaking changes [5][6]. These allow consumers to use ng update to automatically migrate their projects, ensuring a smoother transition for the end user [5][6]. - When publishing libraries, add tslib as a direct dependency because the version of tslib is tied to the TypeScript version used during the library&#39;s compilation [2]. - Be mindful of import cycles; when using partial compilation, "remote scoping" code (which handles complex component interactions) cannot be used, and import cycles will trigger an NG3003 error [7]. Top_results: [1][3][4][2][5]

<title>Creating Libraries • Angular</title> https://angular.dev/tools/libraries/creating-libraries Angular libraries should list any `@angular/*` dependencies the library depends on as peer dependencies. This ensures that when modules ask for Angular, they all get the exact same module. If a library lists `@angular/core` in `dependencies` instead of `peerDependencies`, it might get a different Angular module instead, which would cause your application to break. ... IMPORTANT: The CLI `build` command uses a different builder and invokes a different build tool for libraries than it does for applications. ... - The build system for applications, `@angular/build`, is based on `esbuild`, and is included in all new Angular CLI projects - The build system for libraries is based on `ng-packagr`. It is only added to your dependencies when you add a library using `ng generate library my-lib`. ... a built application ... For this reason, an application that depends on a library should only use TypeScript path mappings that point to the built library. TypeScript path mappings should not point to the library source `.ts` files. ... distribution formats to use when publishing a library: ... | Distribution formats | Details | | --- | --- | | Partial-Ivy (recommended) | Contains portable code that can be consumed by Ivy applications built with any version of Angular from v12 onwards. | | Full-Ivy | Contains private Angular Ivy instructions, which are not guaranteed to work across different versions of Angular. This format requires that the library and application are built with the exact same version of Angular. This format is useful for environments where all library and application code is built directly from source. | ... For publishing to npm use the partial-Ivy format as it is stable between patch versions of Angular. ... ## Ensuring library version compatibility The Angular version used to build an application should always be the same or greater than the Angular versions used to build any of its dependent libraries. For example, if you had a library using Angular version 13, the application that depends on that library should use Angular version 13 or later. Angular does not support using an earlier version for the application. ... If you intend to publish your library to npm, compile with partial-Ivy code by setting `"compilationMode": "partial"` in `tsconfig.prod.json`. This partial format is stable between different versions of Angular, so is safe to publish to npm. Code with this format is processed during the application build using the same version of the Angular compiler, ensuring that the application and all of its libraries use a single version of Angular. ... An application installs many Angular libraries from npm into its `node_modules` directory. However, the code in these libraries cannot be bundled directly along with the built application as it is not fully compiled. To finish compilation, use the Angular linker ... t use the Angular CLI, ... -cli/ <title>Angular Package Format • Angular</title> https://angular.dev/tools/libraries/angular-package-format APF enables a package to work seamlessly under most common scenarios that use Angular. Packages that use APF are compatible with the tooling offered by the Angular team as well as wider JavaScript ecosystem. It is recommended that third-party library developers follow the same npm package format. ... HELPFUL: APF is versioned along with the rest of Angular, and every major version improves the package format. You can find the versions of the specification prior to v13 in this google doc. ... Developers can rely on Angular CLI and ng-packagr (a build tool Angular CLI uses) to produce packages in the Angular package format. See the Creating Libraries guide for more details. ... ## Partial compilation ... Libraries in the Angular Package Format must be published in "partial compilation" mode. This is a compilation mode for `ngc` which produces compiled Angular code that is not tied to a specific Angular runtime version, in contrast to the full compilation used for applications, where the Angular compiler and runtime versions must match exactly. ... To partially compile Angular code, use the `compilationMode` flag in the `angularCompilerOptions` property of your `tsconfig.json`: ... ``` { … "angularCompilerOptions": { "compilationMode": "partial", } } ... Partially compiled library code is then converted to fully compiled code during the application build process by the Angular CLI. ... If your build pipeline does not use the Angular CLI then refer to the Consuming partial ivy code outside the Angular CLI guide. ... As of APF v10, it is recommended to add tslib as a direct dependency of your primary entry-point. This is because the tslib version is tied to the TypeScript version used to compile your library. <title>Angular compiler options • Angular</title> https://angular.dev/reference/configs/angular-compiler-options ### `compilationMode` ... Specifies the compilation mode to use. The following modes are available: ... | Modes | Details | | --- | --- | | `&`#39`;full&`#39`;` | Generates fully AOT-compiled code according to the version of Angular that is currently being used. | | `&`#39`;partial&`#39`;` | Generates code in a stable, but intermediate form suitable for a published library. | ... The default value is `&`#39`;full&`#39`;`. ... For most applications, `&`#39`;full&`#39`;` ... the correct compilation mode. ... Use `&`#39`;partial&`#39`;` for independently published libraries, such as npm packages. `&`#39`;partial&`#39`;` compilations output a stable, intermediate format which better supports usage by applications built at different Angular versions from the library. Libraries built at "HEAD" alongside their applications and using the same version of Angular such as in a mono-repository can use `&`#39`;full&`#39`;` since there is no risk of version skew. ... When `true`, ... style.js`) for `.d ... ` files with a ... ` file. The default value ... `true`. <title>Using Libraries • Angular</title> https://angular.dev/tools/libraries/using-libraries Using Libraries • Angular # Usage of Angular libraries published to npm When you build your Angular application, take advantage of sophisticated first-party libraries, as well as a rich ecosystem of third-party libraries. Angular Material is an example of a sophisticated first-party library. ## Install libraries Libraries are published as npm packages, usually together with schematics that integrate them with the Angular CLI. To integrate reusable library code into an application, you need to install the package and import the provided functionality in the location you use it. For most published Angular libraries, use the `ng add <lib_name>` Angular CLI command. The `ng add` Angular CLI command uses a package manager to install the library package and invokes schematics that are included in the package to other scaffolding within the project code. Examples of package managers include npm or yarn. Additional scaffolding within the project code includes import statements, fonts, and themes. A published library typically provides a `README` file or other documentation on how to add that library to your application. For an example, see the Angular Material documentation. ### Library typings Typically, library packages include typings in `.d.ts` files; see examples in `node_modules/@angular/material`. If the package of your library does not include typings and your IDE complains, you might need to install the `@types/<lib_name>` package with the library. For example, suppose you have a library named `d3`: ``` npm install d3 --save npm install `@types/d3` --save-dev ``` Types defined in a `@types/` package for a library installed into the workspace are automatically added to the TypeScript configuration for the project that uses that library. TypeScript looks for types in the `node_modules/@types` directory by default, so you do not have to add each type package individually. If a library does not have typings available at `@types/`, you may use it by manually adding typings for it. To do this: 1. Create a `typings.d.ts` file in your `src/` directory. This file is automatically included as global type definition. 2. Add the following code in `src/typings.d.ts`: ``` declare module &`#39`;host&`#39`; { export interface Host { protocol?: string; hostname?: string; pathname?: string; } export function parse(url: string, queryString?: string): Host; } ``` 3. In the component or file that uses the library, add the following code: ``` import * as host from &`#39`;host&`#39`;; const parsedUrl = host.parse(&`#39`;https://angular.dev&`#39`;); console.log(parsedUrl.hostname); ``` Define more typings as needed. ## Updating libraries A library is able to be updated by the publisher, and also has individual dependencies which need to be kept current. To check for updates to your installed libraries, use the `ng update` Angular CLI command. Use `ng update <lib_name>` Angular CLI command to update individual library versions. The Angular CLI checks the latest published release of the library, and if the latest version is newer than your installed version, downloads it and updates your `package.json` to match the latest version. When you update Angular to a new version, you need to make sure that any libraries you are using are current. If libraries have interdependencies, you might have to update them in a particular order. See the Angular Update Guide for help. ## Adding a library to the runtime global scope If a legacy JavaScript library is not imported into an application, you may add it to the runtime global scope and load it as if it was added in a script tag. Configure the Angular CLI to do this at build time using the `scripts` and `styles` options of the build target in the `angular.json` workspace build configuration file. For example, to use the Bootstrap 4 library 1. Install the library and the associated dependencies using the npm package manager: ``` npm install jquery --save npm install popper.js --save npm install boo…[truncated] <title>Generating code using schematics • Angular</title> https://angular.dev/tools/cli/schematics Generating code using schematics • Angular # Generating code using schematics A schematic is a template-based code generator that supports complex logic. It is a set of instructions for transforming a software project by generating or modifying code. Schematics are packaged into collections and installed with npm. The schematic collection can be a powerful tool for creating, modifying, and maintaining any software project, but is particularly useful for customizing Angular projects to suit the particular needs of your own organization. You might use schematics, for example, to generate commonly-used UI patterns or specific components, using predefined templates or layouts. Use schematics to enforce architectural rules and conventions, making your projects consistent and interoperative. ## Schematics for the Angular CLI Schematics are part of the Angular ecosystem. The Angular CLI uses schematics to apply transforms to a web-app project. You can modify these schematics, and define new ones to do things like update your code to fix breaking changes in a dependency, for example, or to add a new configuration option or framework to an existing project. Schematics that are included in the `@schematics/angular` collection are run by default by the commands `ng generate` and `ng add`. The package contains named schematics that configure the options that are available to the CLI for `ng generate` sub-commands, such as `ng generate component` and `ng generate service`. The sub-commands for `ng generate` are shorthand for the corresponding schematic. To specify and generate a particular schematic, or a collection of schematics, using the long form: ``` ng generate my-schematic-collection:my-schematic-name ``` ``` ng generate my-schematic-name --collection collection-name ``` ### Configuring CLI schematics A JSON schema associated with a schematic tells the Angular CLI what options are available to commands and sub-commands, and determines the defaults. These defaults can be overridden by providing a different value for an option on the command line. See Workspace Configuration for information about how to change the generation option defaults for your workspace. The JSON schemas for the default schematics used by the CLI to generate projects and parts of projects are collected in the package `@schematics/angular`. The schema describes the options available to the CLI for each of the `ng generate` sub-commands, as shown in the `--help` output. ## Developing schematics for libraries As a library developer, you can create your own collections of custom schematics to integrate your library with the Angular CLI. - An add schematic lets developers install your library in an Angular workspace using `ng add` - Generation schematics can tell the `ng generate` sub-commands how to modify projects, add configurations and scripts, and scaffold artifacts that are defined in your library - An update schematic can tell the `ng update` command how to update your library&`#39`;s dependencies and adjust for breaking changes when you release a new version For more details of what these look like and how to create them, see: ### Add schematics An add schematic is typically supplied with a library, so that the library can be added to an existing project with `ng add`. The `add` command uses your package manager to download new dependencies, and invokes an installation script that is implemented as a schematic. For example, the `@angular/material` schematic tells the `add` command to install and set up Angular Material and theming, and register new starter components that can be created with `ng generate`. Look at this one as an example and model for your own add schematic. Partner and third party libraries also support the Angular CLI with add schematics. For example, `@ng-bootstrap/schematics` adds ng-bootstrap to an app, and `@clr/angular` installs and sets up Clarity from VMWare. An add schematic can also update a project with configuration chan…[truncated]

Align the peer range with the Angular build version.

The production build uses Angular 22 and compilationMode: "partial". Partial compilation avoids full-Ivy exact-version coupling, but it does not make an older application compiler supported. Angular requires the application version to be the same as or newer than the version used to build its libraries.

The package currently admits Angular 19–21, although the repository builds and tests it with Angular 22. Build and test with Angular 19 to support the full range, or narrow the peer range:

Proposed fix 
-    "`@angular/common`": ">=19.0.0 <23.0.0",
-    "`@angular/core`": ">=19.0.0 <23.0.0",
+    "`@angular/common`": ">=22.0.0 <23.0.0",
+    "`@angular/core`": ">=22.0.0 <23.0.0",

Declare @angular/build directly.

angular.json selects @angular/build:ng-packagr and @angular/build:unit-test, but the package manifest declares only @angular-devkit/build-angular. The latter has @angular/build as a transitive dependency, but pnpm’s isolated layout can keep it unavailable to workspace-level builder resolution. This can make ng build, ng test, and prepack fail.

   "devDependencies": {
+    "`@angular/build`": "catalog:",
     "`@angular-devkit/build-angular`": "catalog:",
