Usage

Here's a basic example of how to use xterm-svelte in your SvelteKit application:

<script lang="ts">
    import { Xterm, XtermAddon } from '@battlefieldduck/xterm-svelte';
    import type {
        ITerminalOptions,
        ITerminalInitOnlyOptions,
        Terminal
    } from '@battlefieldduck/xterm-svelte';

    let terminal: Terminal;

    let options: ITerminalOptions & ITerminalInitOnlyOptions = {
        fontFamily: 'Consolas'
    };

    async function onLoad() {
        console.log('Child component has loaded');

        // FitAddon Usage
        const fitAddon = new (await XtermAddon.FitAddon()).FitAddon();
        terminal.loadAddon(fitAddon);
        fitAddon.fit();

        terminal.write('Hello World');
    }

    function onData(data: string) {
        console.log('onData()', data);
    }

    function onKey(data: { key: string; domEvent: KeyboardEvent }) {
        console.log('onKey()', data);
    }
</script>

<Xterm bind:terminal {options} {onLoad} {onData} {onKey} />

FAQ

When should I use onLoad()?

The onLoad() function fires when the xterm terminal is first initialized. You can use this function to perform actions such as initializing xterm addons.

Why is the terminal undefined?

One possible cause is that you called the terminal function before it was initialized. For example, if you run the terminal function in the onMount function without wrapping it with if (terminal !== undefined), it can lead to this issue.
