/yafsn/ - yet another svelte navigator

Motivation

There is a lot of navigation solutions for svelte but many of them are somewhat complicated/or they provide more features than you need with a bunch of extra steps to even begin.

• Do you need "production ready" solution for navigation?
• Do you need accessibility?
• Do you need SSR?
• Do you need "insert feature you won't ever use"?

If your answer to the questions above is NO, then you are in good place.

Installation

npm install yafsn

Usage

Try it here

// App.svelte
<script>
  import { setContext } from "svelte";
  import { createNavigator, makeScreen } from "yafsn";

  import A from "./A.svelte";
  import B from "./B.svelte";

  const screens = {
    A: makeScreen({ component: A }), // Custom screen options
    B: makeScreen(B) // or simplified form
  }

  const navigator = createNavigator({
    screens,
    initialScreen: "A" // OPTIONAL, accepts route name or result of makeScreen
  });
  setContext("navigator", navigator);

  const { screen, navigate } = navigator;
  navigate("A");
</script>

<svelte:component
  this={$screen?.component}
  {...$screen?.props}
/>

// A.svelte - first screen

<script>
  import { getContext } from "svelte";
  const { navigate } = getContext("navigator");

  export let text = "World";

  function goToB() {
    navigate("B");
  }
</script>

<p>Hello {text}</p>
<button on:click={goToB}>Go to B</button>

// B.svelte - second screen
<script>
  import { getContext } from "svelte";
  const { navigate } = getContext("navigator");

  function goToA() {
    navigate("A", { text: "Earth" });
  }
</script>

<p>When we go back to A, Hello World will become Hello Earth</p>
<button on:click={goToA}>Go to A</button>

Helper components

This library exposes simple bare-bones navigator which you can tweak as much you like but if you want to just plug in the screens and call it a day there are some helper components.

Before using helper components make sure to dedupe svelte and yafsn dependency! See: rollup, vite

Navigator wrapper

<script>
  import { makeScreen } from "yafsn";
  import Navigator from "yafsn/components/Navigator.svelte";

  import A from "./A.svelte";
  import B from "./B.svelte";

  const screens = {
    A: makeScreen({ component: A }),
    B: makeScreen(B)
  }

  // All of the screen can access navigator with getContext("navigator")
</script>

<Navigator
  options={{
    screens,
    initialScreen: "A"
  }}
/>
