f
Turboboosted view library in 2 KB with 100 % test coverage. This will probably eventually replace FRZR, but for now it's a separate project.
Install:
npm install @pakastin/fDownload:

f.el(tagName, (attributes), children...)
Creates a HTML element:
var p = f.el('p', { textContent: 'Hello world!' });You can also define children:
var div = f.el('div', null, p);You can also skip attributes:
var p = f.el('p', 'Hello world!' );var div = f.el('div', p);f.svg(tagName, attributes, children...)
Works like f.el, but creates a SVG element:
var circle = f.el('circle', { cx: 50, cy: 50, r: 50 });
var svg = f.el('svg', { width: 100, height: 100 }, circle);Creating components
Components are just POJF (plain old JavaScript functions):
function Item () {
this.el = f.el('p');
}
Item.prototype.update = function (text) {
this.el.textContent = text;
}
var item = new Item();
item.update('Hello world!');
f.mount(document.body, item); // <body><p>Hello world!</p></body>f.list(Component, key, initData);
Automatically inserts, removes and even reorders components. Previous example makes a lot more sense now:
var list = f.list(Item);
f.mount(document.body, list);
list.update([1, 2, 3]); // <body><p>1</p><p>2</p><p>3</p></body>
list.update([2, 3, 4, 5]); // <body><p>2</p><p>3</p><p>4</p><p>5</p></body>You can delay removing the elements by defining a remove-method to a component:
Item.prototype.remove = function (doRemove) {
setTimeout(doRemove, 1000); // remove after 1 second
}f.mount(target, child)
You can mount HTML elements/components to HTML elements/components.
f.mount(document.body, p);
f.mount(document.body, div);
f.mount(div, p);If a component gets mounted, Component.mount/Component.reorder gets called, if present:
Item.prototype.mount = function () {
console.log('mounted');
}
Item.prototype.reorder = function () {
// was already in the DOM when asked to mount
console.log('reordered');
}f.mountBefore(target, child, before)
f.mountBefore(document.body, svg, div);f.unmount(target, child)
Unmounts element/component from element/component. Component.unmount gets called, if present:
Item.prototype.unmount = function () {
console.log('unmounted');
}f.setChildren(target, child)
This cleverly replaces target's children. Children already in the DOM automatically gets moved / kept in place.
