Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@ngx-smz/core

v21.3.0

Published

This project was generated using [Angular CLI](https://github.com/angular/angular-cli) version 19.2.0.

Readme

NgxSmzUi

This project was generated using Angular CLI version 19.2.0.

Code scaffolding

Angular CLI includes powerful code scaffolding tools. To generate a new component, run:

ng generate component component-name

For a complete list of available schematics (such as components, directives, or pipes), run:

ng generate --help

Building

To build the library, run:

ng build ngx-smz-ui

This command will compile your project, and the build artifacts will be placed in the dist/ directory.

PDF export setup

SmzDocumentBuilder and smz-document-viewer use html2pdf.js and jspdf as peer dependencies. Install them in the host application:

npm install html2pdf.js@^0.14.0 jspdf@^4.2.0

Do not add html2pdf.bundle.js to angular.jsonscripts. The library imports html2pdf.js as an ES/CJS module; the Angular bundler resolves html2canvas, jspdf, and dompurify from node_modules.

If the build warns about CommonJS dependencies, add them to allowedCommonJsDependencies in angular.json:

[
  "html2pdf.js",
  "html2canvas",
  "jspdf",
  "dompurify",
  "canvg",
  "raf",
  "core-js",
  "rgbcolor"
]

See the demos app route /document for working examples of the html2pdf renderer.

Publishing the Library

Once the project is built, you can publish your library by following these steps:

  1. Navigate to the dist directory:

    cd dist/ngx-smz-ui
  2. Run the npm publish command to publish your library to the npm registry:

    npm publish

Running unit tests

To execute unit tests with the Karma test runner, use the following command:

ng test

Running end-to-end tests

For end-to-end (e2e) testing, run:

ng e2e

Angular CLI does not come with an end-to-end testing framework by default. You can choose one that suits your needs.

smz-form-group: eventos de alteração e statusChanges

O seletor smz-form-group expõe três saídas (@Output) que parecem relacionadas, mas respondem a gatilhos e comparações diferentes. Todas emitem SmzFormsResponse (o mesmo retorno de getData()), com data, isValid, hasUnsavedChanges, validationMessagesByField, etc.

statusChanges

  • O que é: um EventEmitter do componente — não é o statusChanges do FormGroup do Angular exposto diretamente no template.
  • Quando dispara: após o FormGroup notificar mudança de status, com debounce (config.behaviors.debounceTime, padrão 400 ms). Nesse ciclo o componente roda validação customizada (customValidator), customBehavior, visibilidade e avisos, e em seguida emite o payload atual.
  • Também no carregamento: na primeira carga, em geral emite uma vez com os dados iniciais, exceto se config.behaviors.skipEmitChangesOnLoad estiver ativo ou se runCustomFunctionsOnLoad alterar esse fluxo.
  • Uso típico: reagir a cada ciclo de revalidação/reprocessamento do formulário (ex.: sincronizar UI com erros globais ou com o resultado de customBehavior).

initialStateChanged

  • O que significa: o snapshot atual dos dados (serializado) é diferente do estado inicial guardado quando o formulário realizou resetState() (por exemplo logo após a montagem ou após você restaurar a linha base com APIs do componente).
  • hasUnsavedChanges: no SmzFormsResponse emitido/atualizado, esse flag está alinhado a “mudou em relação ao estado inicial”.
  • Uso típico: habilitar “Salvar” apenas quando há alterações em relação ao registro/modelo original, ou alertar que há rascunho não persistido desde a última baseline.

previousStateChanged

  • O que significa: o snapshot atual dos dados é diferente do estado no ciclo anterior de updateHasChanges() (internamente compara com o último valor conhecido antes de atualizar essa cópia).
  • Contraste com initialStateChanged: não olha apenas para o “primeiro estado após load”, e sim para “mudou desde a última vez que o componente avaliou mudanças” — granularidade passo a passo a cada ciclo que chama updateHasChanges.
  • Uso típico: lógicas que precisam detectar variações incrementais entre emissões consecutivas (por exemplo atualizar apenas um campo derivado quando algo mudou desde o último processamento).

Emitir todas as saídas no primeiro load

Com config.behaviors.emitAllOutputsOnLoad === true, no carregamento o componente pode emitir initialStateChanged, previousStateChanged e statusChanges com o mesmo getData(), para inicializar fluxos que dependem desses handlers sem esperar o primeiro debounce interativo.

Resumo rápido

| Evento | Comparado com | Gatilho principal | |-------------------------|-----------------------------------------------------|----------------------------------------------------------------| | statusChanges | (não é comparação de snapshot) | Ciclo pós mudança de status do formulário (+ debounce) + carga inicial conforme comportamentos | | initialStateChanged | Baseline da última resetState() / estado inicial | Mudança do payload atual em relação a esse baseline | | previousStateChanged | Snapshot do ciclo anterior de updateHasChanges | Mudança desde o último processamento de “has changes” |

Para detalhes de implementação (ordem das chamadas, emitChanges, runStatusChangesOnConfigUpdate, etc.), consulte form-group.component.ts e form-viewdata.ts.
