Resize a companion

Change the rendered dimensions without recreating the companion or replacing its artwork. Use this for compact widgets and larger onboarding scenes. Try both sizes below.

Try it. It’s alive.LIVE DEMO

Drag the pet, or focus it and use arrow keys. Reduced motion follows your system settings.

Preparing example…

Signature

pet.setSize(width: number, height: number): void

Parameter or method	Behavior
width	Positive width in CSS pixels.
height	Positive height in CSS pixels.
resize event	Payload: { width, height }.

How it works

Both values must be finite and greater than zero. They control the character, not a fixed size for its speech bubble. Resizing ends the current drag, recalculates placement and emits resize. Keep the dimensions within your container on narrow screens.

Use it in your project

Choose your stack. Each example includes setup and cleanup. For Vanilla, pass a mounted container at least 360px tall and keep the returned cleanup. Method names are identical across frameworks.

Vanilla

import { createPet } from '@flowscape-ui/mimimo';
import { mochi } from '@flowscape-ui/mimimo-pet-mochi';

// Call after your container mounts.
export function mountCompanion(container: HTMLElement) {
  const lifetime = new AbortController();
  const pet = createPet({
    character: mochi,
    container,
    anchor: 'center',
  });
  pet.setSize(96, 96);
  return () => {
    lifetime.abort();
    pet.destroy();
  };
}
// Keep the returned cleanup and call it when the view is removed.

React

'use client';
import { useEffect, useRef } from 'react';
import { createPet } from '@flowscape-ui/mimimo';
import { mochi } from '@flowscape-ui/mimimo-pet-mochi';

export default function Companion() {
  const host = useRef<HTMLDivElement>(null);
  useEffect(() => {
    const container = host.current;
    if (!container) return;
    const lifetime = new AbortController();
    const pet = createPet({
      character: mochi,
      container,
      anchor: 'center',
    });
    pet.setSize(96, 96);
    return () => {
      lifetime.abort();
      pet.destroy();
    };
  }, []);
  return <div ref={host} style={{ height: 360, position: 'relative' }} />;
}

Vue

<script setup lang="ts">
import { ref, onMounted, onBeforeUnmount } from 'vue';
import { createPet } from '@flowscape-ui/mimimo';
import { mochi } from '@flowscape-ui/mimimo-pet-mochi';
const host = ref<HTMLElement | null>(null);
let cleanup: (() => void) | undefined;
onMounted(() => {
  const container = host.value;
  if (!container) return;
  const lifetime = new AbortController();
  const pet = createPet({
    character: mochi,
    container,
    anchor: 'center',
  });
  pet.setSize(96, 96);
  cleanup = () => {
    lifetime.abort();
    pet.destroy();
  };
});
onBeforeUnmount(() => cleanup?.());
</script>

<template>
  <div ref="host" style="height: 360px; position: relative" />
