API

type(target: HTMLElement, ...steps: any[]) => Promise<void>;
type(target: { node: HTMLElement, textAccessor: 'textContent' | 'placeholder' }, ...steps: any[]) => Promise<void>;

The module exports a single function, type, which takes a target element as its first argument, and any number of additional arguments as the steps to perform. Additional arguments perform actions based on their type:

Usage

The most basic usage of type is providing a target element and a string to type.

import { type } from '@tomskopek/typical';

type(element, 'text');

Pausing

In order to pause typing at any point, pass a number of milliseconds to pause.

type(element, 'Hello', 1000, 'Hello world!');

Looping

In order to loop, pass type as a parameter to itself at the point at which you'd like to start looping. It can be helpful to alias type as loop to be explicit.

import {
    type,
    type as loop
};

const steps = [1000, 'Ready', 1000, 'Set', 1000, 'Go'];

type(element, ...steps, loop);

To loop a finite amount, pass your steps multiple times.

type(element, ...steps, ...steps, ...steps);

Waiting

When passed a Promise, type will wait for it to resolve before continuing. Because type itself returns a Promise, that means you can wait on a set of steps to complete before starting another.

const init = type(target, 'In a moment...', 500);

type(target, init, 'start', 500, 'looping', loop);

Functions

Function arguments are passed the target element, and can be useful for operating on the target element between steps. If you return a Promise, type will wait for it to resolve.

const toggle = (element) =>
    element.classList.toggle('is-typing');

type(target, toggle, 'Type me', toggle);
