# @thefarce/loom

## What is this?

Loom is a tool for weaving form data with content data in nodejs.  It does
this by using elements of the Unified.js toolkit for parsing text into
abstract syntax trees (AST).

The fundamental idea of Loom is that presentation and content are orthogonal
dimensions of data.  A communication has values in these two dimensions
integrated into a coherent whole.

## When should I use this?

When you want to blend form (such as HTML) with content (such as JSON) into
a single document.  Unlike other systems, Loom does not require writing to
or reading from files.

## Installation

`$` `npm install @thefarce/loom`

## Usage Example

For more thorough usage examples, see the `examples` directory and refer to
the [documentation](./docs/usage.md).

```js
import {
	interpolateTree,
	transform,
} from '@thefarce/loom'

const initial = htmlToAst('<p>Hello, {name}!</p>'),

const transformed = interpolateTree(
	transform(initial, ...transformers),
	{ name: 'Othello' },
);

console.log(astToHtml(transformed));
```

Running this script produces the following output:

```html
<p>Hello, Othello!</p>
```
