# [](https://github.com/arcanis/mono-layout)
> Fast implementation of a browser-like text layout engine, for Node and browsers
[]() []()
## Features
- Soft-wraps any text to the given width
- Automatically justifies the text to fit the specified width if requested
- Can collapse text on demand (`white-space: pre`, but more configurable)
- Keeps an internal state to map between the original and transformed text coordinates
- Only updates the part of the text that has changed for better performances
- Shipped as NPM package using WebAssembly (portable, even accross browsers)
- Also available as a zero-dependencies C++ library
Currently not implemented:
- Font width support (all characters are assumed monospaces)
- Unicode support (all characters are assumed to be ASCII)
## Installation
```
$> yarn add mono-layout
```
## Usage
```js
const {TextLayout} = require(`mono-layout/sync`);
const faker = require(`faker`);
const textLayout = new TextLayout();
textLayout.setConfiguration({columns: 80, justifyText: true});
textLayout.setSource(faker.lorem.paragraphs(10, `\n\n`));
console.log(textLayout.getTransformedSource());
```
Note that the library is also available through an asynchronous endpoint (used by default when requiring `mono-layout`). You typically will want to use this endpoint if your code is expected to work within browsers, since they may disallow WebAssembly to be compiled in the main thread. Here's what the code looks like with the asynchronous initialization:
```js
const tlPromise = require(`mono-layout/async`);
const faker = require(`faker`);
tlPromise.then(({TextLayout}) => {
const textLayout = new TextLayout();
textLayout.setConfiguration({columns: 80, justifyText: true});
textLayout.setSource(faker.lorem.paragraphs(10, `\n\n`));
console.log(textLayout.getTransformedSource());
});
```
## Tests
### Testing the library
```
$> apt-get install catch
$> make tests DEBUG=1
```
### Testing the JS module
```
$> yarn
$> node sources/run-tests.js
```
