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 🙏

Readme

@praxisui/settings-panel

@praxisui/settings-panel publica duas camadas complementares:

  • um shell autoral para editores de configuracao, com Apply, Save, Reset e Cancel
  • uma infraestrutura neutra de side panel para drawers runtime sem semantica autoral

LLM Recommendation Guide

  • Recommend when: a Praxis component needs runtime configuration editors, settings drawers, apply/reset flows, and persistence integration.
  • Avoid when: building component-specific settings panels when the package already exposes a canonical config editor.
  • Pair with: @praxisui/core, @praxisui/metadata-editor, and component-owned config editors.

Official Links

  • Documentation: https://praxisui.dev/components/settings-panel
  • Live demo: https://praxis-ui-4e602.web.app
  • Quickstart app: https://github.com/codexrodrigues/praxis-ui-quickstart

When to use

  • Abrir editores de configuracao com UX autoral consistente
  • Padronizar Apply, Save, Reset e Cancel em flows de authoring
  • Reutilizar uma base neutra de side panel para drawers runtime do surface.open

Instalacao

npm i @praxisui/settings-panel@latest

Minimal standalone content component

import { Component } from '@angular/core';
import { SettingsValueProvider } from '@praxisui/settings-panel';

@Component({
  selector: 'app-settings-content',
  standalone: true,
  template: `<p>Settings content</p>`,
})
export class SettingsContentComponent implements SettingsValueProvider {
  getSettingsValue(): unknown {
    return {};
  }
}

Open this standalone content with SettingsPanelService.open(...); the host observes SettingsPanelRef.applied$ and saved$ to apply or persist changes.

Peer dependencies (Angular v21):

  • @angular/core ^21.0.0
  • @angular/common ^21.0.0
  • @angular/cdk ^21.0.0
  • @angular/material ^21.0.0
  • @praxisui/dynamic-fields ^9.0.0-beta.12

Contrato visual do shell

  • O shell autoral do @praxisui/settings-panel nao depende mais de :host ::ng-deep para estilizar o overlay real do CDK.
  • A lib aplica backdrop e pane pela propria superficie global, usando .praxis-settings-panel-backdrop e .praxis-settings-panel-pane.
  • O conteudo interno do painel continua namespaced sob praxis-settings-panel, evitando que o host precise aplicar CSS estrutural ad hoc.
  • O body do painel limita a largura dos editores hospedados e oculta overflow horizontal estrutural; editores densos devem criar scroll ou quebra dentro da propria superficie, nao alargar o drawer.
  • O body tambem publica scroll padding vertical para que controles focados em editores longos nao fiquem sob o header ou o footer fixos; ajuste esse espaco por token quando o host alterar alturas ou densidade do shell.
  • Quando o host nao publica tokens --md-sys-color-*, a lib usa fallbacks internos para superficie, texto, borda e scrim. Isso evita drawers transparentes em hosts que publicam apenas tokens proprios.
  • Hosts devem tratar esses fallbacks como baseline operacional; customizacao visual continua sendo opt-in por token ou por classes canonicas da lib, nao por override local do app consumidor.

Visao Geral

1. Shell autoral

  • Abra um painel com SettingsPanelService.open(...) informando um componente standalone como conteudo.
  • O componente implementa SettingsValueProvider para habilitar ou desabilitar as acoes do rodape.
  • O host observa SettingsPanelRef.applied$ e saved$ para aplicar e persistir mudancas.
  • O shell autoral agora pode ligar resize horizontal compartilhado pela base comum, com resizable, minWidth, maxWidth e persistSizeKey.
  • O ref base pode observar sizeChanged$ quando o host precisar reagir a resize programatico ou interativo.
  • expanded: true abre o painel ja expandido de forma efetiva, respeitando maxWidth.
  • Expandir temporariamente o painel nao substitui a preferencia persistida do usuario; apenas o resize manual continua sendo persistido.
  • Quando um editor autoral tentar abrir outro painel sobre o atual, o shell passa pela mesma mediacao de fechamento do proprio painel. Se onBeforeClose vetar o fechamento, a substituicao nao acontece.

2. Drawer runtime

  • A infraestrutura base neutra fica disponivel por BaseSidePanelService.
  • O shell runtime dedicado fica disponivel por SurfaceDrawerComponent.
  • O bridge canonico de runtime e providePraxisSurfaceDrawerBridge().
  • Esse drawer runtime nao deve mostrar Apply, Save, Reset ou Cancel por heranca.
  • O runtime drawer aceita width, minWidth, maxWidth, resizable e persistSizeKey; o handle visual so aparece quando resizable=true.
  • Quando persistSizeKey estiver presente, a largura volta no proximo open do mesmo painel.

Fronteira canonica

  • SettingsPanelService e SETTINGS_PANEL_BRIDGE pertencem a authoring/configuracao.
  • SURFACE_DRAWER_BRIDGE pertence ao runtime de surface.open.
  • Ambos compartilham a mesma infraestrutura base de side panel, mas com shells diferentes.

Customizacao visual

Tokens autorais

  • --pfx-settings-panel-width
  • --pfx-settings-panel-width-expanded
  • --pfx-settings-panel-max-width
  • --pfx-settings-panel-header-height
  • --pfx-settings-panel-body-padding
  • --pfx-settings-panel-footer-padding
  • --pfx-settings-panel-scroll-padding-start
  • --pfx-settings-panel-scroll-padding-end
  • --pfx-backdrop
  • --pfx-backdrop-blur

Tokens neutros de side panel

  • --pfx-side-panel-width
  • --pfx-side-panel-max-width
  • --pfx-side-panel-header-height
  • --pfx-side-panel-backdrop
  • --pfx-side-panel-motion-duration-enter
  • --pfx-side-panel-motion-duration-exit

Hosts devem inferir skin, densidade, spacing e motion sobre os tokens --pfx-side-panel-* quando o objetivo for drawer runtime compartilhado.

Classes canonicas de overlay

  • .praxis-settings-panel-backdrop: scrim e blur do overlay real anexado no cdk-overlay-container
  • .praxis-settings-panel-pane: posicionamento, altura e z-index do pane autoral

Regra de integracao:

  • prefira tokens CSS para skin e densidade
  • use as classes canonicas acima apenas quando precisar ajustar o overlay autoral inteiro
  • nao reintroduza :host ::ng-deep no host para tentar alcancar o backdrop real do CDK

API principal de authoring

Servico

  • open(config: SettingsPanelConfig): SettingsPanelRef
    • config.id: string
    • config.title?: string
    • config.expanded?: boolean
    • config.resizable?: boolean
    • config.persistSizeKey?: string
    • config.minWidth?: string
    • config.maxWidth?: string
    • config.diagnostics?: SettingsPanelDiagnosticsConfig
    • config.content: { component: Type<any>; inputs?: Record<string, any> }

Ref

  • applied$: Observable<any>
  • saved$: Observable<any>
  • closed$: Observable<SettingsPanelCloseReason>
  • sizeChanged$: Observable<{ width: string }>
  • apply(value: any)
  • save(value: any)
  • reset()
  • updateSize(width, options?)
  • close(reason?: SettingsPanelCloseReason)

Injection Tokens

  • SETTINGS_PANEL_DATA
  • SETTINGS_PANEL_REF

Contrato do editor

O componente hospedado deve expor:

  • isDirty$: Observable<boolean>
  • isValid$: Observable<boolean>
  • isBusy$: Observable<boolean>
  • getSettingsValue(): any

Opcionais:

  • onSave?()
  • reset?()
  • suggestExpanded$?
  • preferredWidth$?
  • requiresFullHeight$?
  • onPanelResize?
  • onBeforeClose?
  • onFocusChange?
  • customActions$?
  • hideDefaultButtons$?

Agentic Authoring Contract

praxis-settings-panel publica um manifesto executavel em PRAXIS_SETTINGS_PANEL_AUTHORING_MANIFEST.

Esse contrato governa somente o shell autoral:

  • identidade e titulo do painel
  • modo de abertura e substituicao mediada por onBeforeClose
  • largura, resize e persistencia de tamanho
  • comportamento de Apply
  • comportamento de Save
  • comportamento de Reset
  • envelope do editor hospedado
  • diagnosticos baseados em dirty, valid e busy

O manifesto nao define semantica de FormConfig, TableConfig, ListConfig ou qualquer outro documento de consumidor. Quando a intencao do usuario alterar a configuracao interna de um editor hospedado, a operacao deve ser delegada para o manifesto do componente dono daquele documento.

Regras do contrato:

  • Apply emite applied$ com getSettingsValue() e nao fecha o painel.
  • Save usa onSave() quando existir, usa getSettingsValue() como fallback, emite saved$ e fecha com motivo save.
  • Reset e destrutivo, exige confirmacao, chama reset() quando existir e emite reset$.
  • Apply e Save continuam bloqueados por dirty=false, valid=false ou busy=true.
  • O editor hospedado deve implementar SettingsValueProvider quando o fluxo for autoral.
  • Inputs persistidos do editor devem permanecer serializaveis.
  • diagnostics controla somente a visibilidade dos diagnosticos do shell (statusMessage, motivo de desabilitacao, busy e estado invalido); ele nao altera as regras de bloqueio de Apply/Save.

Diagnostics

SettingsPanelConfig.diagnostics e opcional e preserva o comportamento historico quando omitido:

{
  showStatusMessage?: boolean;
  showDisabledReason?: boolean;
  showBusyState?: boolean;
  exposeValidationState?: boolean;
}

Use essa configuracao para ajustar a superficie visual do shell autoral. O estado canonico continua vindo de SettingsValueProvider.isDirty$, isValid$ e isBusy$.

onBeforeClose

onBeforeClose pertence ao contrato canonico de authoring. Ele pode:

  • permitir cleanup antes do fechamento
  • vetar o fechamento retornando false
  • ser usado tanto no Cancel local quanto na tentativa de substituir um painel autoral ja aberto

Na pratica:

  • Cancel, Esc e backdrop continuam passando pela confirmacao de descarte quando houver dirty
  • antes disso, o shell consulta onBeforeClose
  • se onBeforeClose retornar false, o painel continua aberto e o host nao substitui silenciosamente a sessao atual

Exemplo de authoring

const ref = this.settingsPanel.open({
  id: `filter.${this.configKey}`,
  title: "Configuracoes do filtro",
  content: { component: FilterSettingsComponent, inputs: currentConfig },
});

ref.saved$.pipe(take(1)).subscribe((cfg: FilterConfig) => {
  const safe = validateConfig(cfg);
  applyChanges(safe);
  persistConfig(safe, "Configuracoes salvas");
});

Resize e persistencia

  • resizable fica ligado por padrao no shell autoral
  • persistSizeKey controla a restauracao da largura no proximo open do mesmo painel
  • sizeChanged$ emite a largura aplicada de fato
  • resize manual persiste a largura
  • expanded e toggleExpand() nao sobrescrevem a largura persistida; eles sao tratados como estado transitório de layout
