🐕 bepis

Dynamic HTML + CSS in JavaScript. Implemented using a custom parser for a new HTML templating DSL.

It Is On Npm

npm i bepis

Examples

Simple keyed list, play with it here:

First, import:

import { w, clone } from "bepis";

Then set up some data:

const myItems = [
  { name: "Screw", description: "Part", key: "a3" },
  { name: "Moxie", description: "Intangible", key: "x5" },
  { name: "Sand", description: "Material", key: "p4" },
];
const newName = "Mojo";

Make some views:

const KeyedItem = item =>
  w` ${item.key} 
    li p, 
      :text ${item.description}.
      a ${{ href: item.url }} :text ${item.name}..`;

const SingletonList = items =>
  w` ${true} 
    ul :map ${items} ${KeyedItem}`;

Render the data and mount the view to the document

SingletonList(myItems)(document.body);

Make a change and see it

const myChangedItems = clone(myItems);
myChangedItems[1].name = newName;

setTimeout(() => SingletonList(myChangedItems), 2000);

:text, :map and :comp directives.

• Use :text to insert text, and :map to insert lists, as in the above example.
• Use :comp to insert components:

  w`
    main,
      h1 ${"Demo"}.
      :comp ${myChangedItems} ${SingletonList}..`

Basics

• Use template literals tagged with w. This creates a 'bepis'
• Use ',' operator to save an insertion point
• Use '.' operator to load an insertion point
• <tag name> ${attributes} ${styles} is the format.
• Whitespace is ignored.

Up next

• minimal diffing with updator functions.
