Every even t application that needs that product card imports the library, ensuring visaal and behavisolaire consistency.

Setting Up Your Nx Workspace for Feature Libraries

Warunki wstępne i Installation

Before you can create reusable facilitarie libraries, you need an Nx workspace. If you 're new to Nx, starte by installing the CLI globally:

Xi1; Xi1; FLT: 0 Xi3; Xi3;

Stworzenie nowej przestrzeni roboczej with a preset that matches your tech stack. For a React- based design system using TypeScript, run:

Xiv1; Xiv1; FLT: 1 Xiv3; Xiv3;

You can also start with an empty workspace andd framework later. Nx supports monorepos with multiple frameworks, but for design considency it 's often beset to stick with on e UI framework per work workspace. The CLI will ask about CI, tect runners, andd bundler preferences - choose options that altern with your team' s existing tooling. For most desigmend- focused projects, a default setup with Jess, cypress, and Vite or Webpack work well.

Generating a New Library

One che thee workspace e s ready, generating a feature library is prospecforward. Use thee Nx generator for your framework. For React, the command is:

Xiv1; Xiv1; FLT: 2 Xiv3; Xiv3;

To jest specjalne:

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Directory Xi1; Xi1; FLT: 1 Xi3; Xi3; - a folder that groups related libraries (np., Xi1; Xi1; FLT: 3 XI3; Xi3; FOr cross- project quiures).
  • (Dz.U. L 311 z 15.11.2014, s. 1).
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; importPath Xi1; Xi1; FLT: 1 Xi3; Xi3; - definites how Xir projects will import the e library (np., Xi1; Xi1; FLT: 4 XI3; Xi3;).

Nx generates all the boilerplate - previo1; FLT: 5 supports 3; Supports 3; FLT: 6 supports 3; Supports 3; ith build / tett propports, and an initiatial apel contribuent. The library 's propments 1; FLT: 7 supports 3; Supports 3; barrel file reexport only the public API; everthing internal stays private. Thii prevents preventable coupling and enforces boundaries.

If your design workflow involves Angular or Vue, thee CLI syntax differs slightly (e.g., Xi1; Xi1; FLT: 8 X3; Xi3;), but the concepts remain identical. For a detad reference, consult the Official Agreement 1; Xi1; FLT: 0 X3; Xi3; Nx documentation X1; XIs.

Strukturing a Feature Library for Maximum Reusability

Component Organization

Inside thee generated library folder (indi.1; indiv1; FLT: 9 indiv3; indiv3;), you 'll find a entil 1; indiv1; fLT: 10 indiv3; indictory. organize contribuents into subfolders by difcuure area rather than by type. For example, if te library implements a contribuments; user profile contribute quenture, structure like this:

  • (zob. pkt 2.1.1.1 niniejszego załącznika)
  • Xi1; Xi1; FLT: 15 Xi3; Xi3; - Custom hooks: Xi1; Xi1; FLT: 16 Xi3; Xi3;, Xi1; FLT: 17 Xi3; Xi3;.
  • - API calls or state management logic.
  • - Scpedd CSS or CSS- in- JS modules.
  • - Default images, SVGs, fonts.

Keep thee surface area exposed the barrel file minimal. Only re- export thee main difficulture configuent (np., display1; disactus; FLT: 21 disabled 3; disable3;) and perhaps one e compomple object for configuation. Internal utilties should be stay hidden. Thii s prevents consumers from depensiing on implementation details that might change.

For each contribuent, write a environ1; Xi1; FLT: 22 contribution 3; Xi3; file if you use Storybook. Integrating Storybook with Nx is automatic when you generate thee workspace, and it provides a live playground for designans to review accordants with out spinning up the full application.

Shared Styles and Themes

A reusable design tokens via CSS conservenes or a theme object that can be overridden at thee application level. For example, thee library might consume a difference 1; FLT: 23 contributes our; FLT: 23 contributes; fláble the app 's roott. Nx workspaces often have a separate 1; FLT: 24 contribuild 3d; 3library the secure library ary and applications. Nx workspaces often have a separate 1; FLT: 24 contribuilmary color onplace onplace everalttes instres.

If you prefer a utility- first CSS framework like Tailwind, Nx can be configured to share thee Tailwind configuation across libraries. Create a base amend1; IF: 25 contribution 3; IM 3; in the workspace root, and each library extends it. This avoids duplicate configuration while allowing library- specific overrides for complex configurants.

Asset Management

Feature libraries częstokroć potrzebne są testy statystyczne, takie jak: foreholder images, default avatary, or szkieleton loading animations. Store these in thee employment 1; omph; FLT: 26 employ3; oms place of your library. When building thee library for publishing, Nx copie thee assets to thee out put directoria. If thee library is only consumed locally with thee monerepo, path aliases handle thee resolutionion automatically.

For SVGs, consider using inline React contribuents (via indiv1; indiv1; FLT: 27 contribution 3; indiv3;) to avoid extra HTTP requests. Nx 's build configuation supports this out of the box for React libraries.

Developing andManaging Feature Libraries

Using Nx Dependency Graph

One of Nx 's strongess facilites is the dependency graph, which visualizas how libraris and applications relate to each each teir. After creating sereal faciure libraries, run behind 1; FLT: 28 hair3; dis3; to see thee diagrams. This helps avoid circular dependencies and accorreres that your architecture behs layerer (e.g., applications depend on haire librarises, whh depended oun UI librarises, whch depended on tokens).

Nx also enforces tags andmodule boundary rules. In the indis1; In the indis1; FLT: 29 indis3; Ib3; configuation, you can define tags like 1; Ib1; FLT: 30 indis3; Ib1; Ib1; FLT: 31 indis3; Ib1; Ib1; Ib1; IbD: 32 indis3; Ib3; AND set districts (e.g., a discure librarie cannot import another dishary directly - only distrigh a shard UI layer). This prevents the messy dependidependy ency hell thatt ofter ofter ofl teen plagees monorees.

Versioning andd Publishing

When your guire library is stable enough tu be consumed by multiple teams, version it using signal 1; disag1; FLT: 0 disag3; Is stable enough tu be consumed by multiple teams, version in hand witch tools like disag1; IG: 33 disagne 3; IR 3; IR 1; OR disag1; IG: 34 dissoning 3; IG 3; IG 3; TO automate version bumps and changelogs.

Te wywody nie są zgodne z przepisami 1; Xi1; FLT: 37, Xi3; with a Xi1; Xi1; FLT: 38, Xi3; FLT: 38, Xi3; ready for npm publish. You can then push te internal registry (like Verdaccio) or to npm 's public registry. Aplikacje te są monorepo can install thee library as a regular dependency, though for maximum performance keep everthing inside thee te same workspace.

Eun if you never publish externally, versioning inside thee monorepo is valuable. Nx 's affected commands ensure thatt when you modify a library, only the applications that depend on it are rebuilt and retested. Thi' s drastically cuts down CI time for large workspaces.

Integriting Feature Libraries into Applications

Once thee featuree library is created and d populated with contribuents, integrating it into an application is a matter of adding it a dependency in thee application 's eng.1; EIG1; FLT: 39 contribution 3; IGD importing the module. For a React application, update the application 1; IGF: 40 contribution 3; IGF:

{
 "compilerOptions": {
 "paths": {
 "@myworkspace/shared/feature-library": ["libs/shared/feature-library/src/index.ts"]
 }
 }
}

Nx generators often set this up automatically, but you can manually add pats for libraries you create later. Then in your application code:

Xiv1; Xiv1; FLT: 42 Xiv3; Xiv3;

Pass required props (like user data, callbacks) and optionally override them e e via context. If thee difficulture library included des lazy- loadable modules, use ideas 1; individu1; FLT: 43 context; context; or Angular routing to load them on requite code splitting works automatically when thee library is built with the correcort module format (ESM).

Bett Practices for Designing Reusable Libraries

Creatyng truly reusable fabule libraries requires more than juss moving files around. Follow these principles to maximize your desin workflow speed:

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Definite a clear contract: Xi1; Xi1; FLT: 1 Xi3; Xi3; Each library should export a limited public API (confidents and major hooks). Keep internal module private.
  • Rex on props and slots to allow consumers to customize behavor, rather than forcing a rigid structure.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Write extensive documentation: Xi1; Xi1; FLT: 1 Xi3; Xion3; Usie Storybook storie, typedoc comments, anda README. designers andd developers need to understand props, themes, and usage examples quickling.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Version your designs too: Xi1; Xi1; FLT: 1 Xi3; Xi3; Maintain a changelog for design changes (color updates, spacing modifications) so that application teams can plan migrations.
  • Xi1; Xi1; FLT: 0 XI3; XI3; Automate visual regression testing: XI1; XI1; FLT: 1 XI3; XI3; XI3; Tools like Chromatic or Percy integrated with Nx can catch unintended style changes when a library is updated.
  • W przypadku gdy w wyniku badania nie można określić, czy dany produkt jest zgodny z wymogami określonymi w pkt 1, należy podać numer identyfikacyjny produktu, który ma być zastosowany w celu uzyskania zgodności z wymogami określonymi w pkt 1.

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Accelerated prototyping: Xi1; Xi1; FLT: 1 Xi3; Xi3; Designers can request a Xiure library, and with a sprint the e library is acceptable for all new projects. No more houting for developers to re-implement the same UI Pattern.
  • Rev.1; Xi1; FLT: 0 X3; Xi3; Consistent user experience: Xi1; Xi1; FLT: 1 XI3; XI3; Since every application consumes the same Xionent, users see identical behavor and styling across products. This is is especially valuable for entreprises with multiple customer- facing portals.
  • Reduced technical debt: index1; index1; index1; FLT: 1 index3; index3; Fixes are applied ion one place. When a bug is discrevered in thee profile Editor, the library y maintainer patches it, and all consuming apps pick up the fix after a version bump and rebuild.
  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Better collaboratioon: Xi1; Xi1; FLT: 1 Xi3; Xi3; The monorepo structure constructure construgnes designans to directly review construent implementations (via Storybook) and provide e fediback before thee library is released.
