modus-angular-navbar-usage

A detailed guide for using the Modus Navbar component in Angular. It covers search expansion, button visibility, event handling, and state management.

In plain words
What is it for?
Use it when configuring navbar buttons, connecting search and menu controls, supplying user details, or synchronizing navbar state with Angular signals.
Why use it?
It helps prevent common navbar issues, such as search not expanding or controls becoming hidden because their visibility was not set.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

modus-angular-navbar-usage scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Comprehensive guide for using the Modus Navbar component in Angular, covering search expansion, button visibility, event handling, and state management.

CRITICAL: Search Input Expansion

DO: Set Both search and searchInput in Visibility

For search to expand, you MUST set both visibility flags:

<modus-navbar
  [userCard]="userCard"
  [visibility]="{ user: true, search: true, searchInput: true }"
  [searchInputOpen]="searchInputOpen()"
  (searchClick)="handleSearchClick($event)"
  (searchInputOpenChange)="handleSearchInputOpenChange($event)"
/>

DO: Two-Way Bind Search State

readonly searchInputOpen = signal<boolean>(false);

handleSearchClick(event: MouseEvent | KeyboardEvent): void {
  this.searchInputOpen.set(!this.searchInputOpen());
}

handleSearchInputOpenChange(event: boolean): void {
  if (this.searchInputOpen() !== event) {
    this.searchInputOpen.set(event);
  }
}

Button Visibility Patterns

DO: Set Visibility for Each Button

<modus-navbar
  [userCard]="userCard"
  [visibility]="{
    user: true,
    search: true,
    searchInput: true,
    help: true,
    apps: true,
    notifications: true,
    mainMenu: true
  }"
/>

Default visibility settings:

readonly visibility = input<INavbarVisibility | undefined>({
  ai: false,
  apps: false,
  help: false,
  mainMenu: false,
  notifications: false,
  search: false,
  searchInput: false,
  user: true,
});

Event Handling Patterns

DO: Handle Events with Correct Types

handleSearchClick(event: MouseEvent | KeyboardEvent): void {
  this.searchInputOpen.set(!this.searchInputOpen());
}

handleMainMenuOpenChange(event: boolean): void {
  this.mainMenuOpen.set(event);
}

handleSearchChange(event: { value: string }): void {
  this.lastSearch.set(event.value);
}

State Management Patterns

DO: Use Signals for Navbar State

export class NavbarComponent {
  readonly searchInputOpen = signal<boolean>(false);
  readonly lastSearch = signal<string>('');
  readonly mainMenuOpen = signal<boolean>(false);
  readonly notificationsMenuOpen = signal<boolean>(false);
  readonly appsMenuOpen = signal<boolean>(false);
}

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
