Symfony UX Typed

Edit this page

Symfony UX Typed is a Symfony bundle integrating Typed in Symfony applications. It is part of the Symfony UX initiative.

Typed is a complete and easy to use animated typed texts. Just enter the strings you want to see typed, and it goes live without complexity.

Typed showing messages

Installation

Caution

Before you start, make sure you have StimulusBundle configured in your app.

Install the bundle using Composer and Symfony Flex:

1
$ composer require symfony/ux-typed

If you're using WebpackEncore, install your assets and restart Encore (not needed if you're using AssetMapper):

1
2
$ npm install --force
$ npm run watch

Usage

Typed works using a list of strings and will manage typing them on your page. It comes with a lot of parameters to customize the way the strings are typed: speed, cursor, delays and smart backspace are some incredible parameters you can use.

The main usage of Symfony UX Typed is to use its Stimulus controller to initialize Typed:

<div>
    I created this UX component because
    <span {{ stimulus_controller('symfony/ux-typed', {
        strings: ['I ❤ Symfony UX', 'Symfony UX is great', 'Symfony UX is easy']
    }) }}></span>
</div>

That's it! Typed now shows the messages defined in the strings argument. You can customize the way those messages are typed. Parameters are exactly the same as for the typed library

        smartBackspace: true,
        startDelay: 100,
        backSpeed: 20,
        backDelay: 100,
        loop: true,
        showCursor: true,
        cursorChar: '✨'
    }) }}></span>
</div>

Extend the JavaScript Controller

Symfony UX Typed allows you to extend its default behavior using a custom Stimulus controller:

// assets/controllers/mytyped_controller.js

import { Controller } from '@hotwired/stimulus';

export default class extends Controller {
    initialize() {
        this._onPreConnect = this._onPreConnect.bind(this);
        this._onConnect = this._onConnect.bind(this);
    }

    connect() {
        this.element.addEventListener('typed:pre-connect', this._onPreConnect);
        this.element.addEventListener('typed:connect', this._onConnect);
    }

    disconnect() {
        // You should always remove listeners when the controller is disconnected to avoid side-effects
        this.element.removeEventListener('typed:connect', this._onConnect);
        this.element.removeEventListener('typed:pre-connect', this._onPreConnect);
    }

    _onPreConnect(event) {
        // Typed has not been initialized - options can be changed
        console.log(event.detail.options); // Options that will be used to initialize Typed
        event.detail.options.onBegin = (typed) => {
            console.log("Typed is ready to type cool messages!");
        };
        event.detail.options.onStop = (typed) => {
            console.log("OK. Enough is enough.");
        };
    }

    _onConnect(event) {
        // Typed has just been intialized and you can access details from the event
        console.log(event.detail.typed); // Typed instance
        console.log(event.detail.options); // Options used to initialize Typed
    }
}

Then in your template, add your controller to the HTML attribute:

<html lang="en">
    <head>
        <title>Typed</title>
        {# ... #}
    </head>
    <body {{ stimulus_controller('mytyped')|stimulus_controller('symfony/ux-typed', {
        strings: ['...'],
    }) }}>
        {# ... #}
    </body>
</html>

Note

Be careful to add your controller before the Typed controller so that it is executed before and can listen on the typed:connect event properly.
