# Serve static file through koa-router
[![Build Status](https://travis-ci.org/OwenCalvin/static-koa-router.svg?branch=master)](https://travis-ci.org/OwenCalvin/static-koa-router)

## Installation
```
npm i static-koa-router
```
```
yarn add static-koa-router
```

### Usage
`Serve(dirPath: string, router: Router, options?: Options)`
You simply need to pass the **dir path** at the first parameter, the **router instance** (koa-router) at the second parameter and optionaly the **options** at third parameter.

##### Options
 - `maxage` Browser cache max-age in milliseconds. defaults to 0
 - `hidden` Allow transfer of hidden files. defaults to false
 - `index` Default file name, defaults to 'index.html'
 - `defer` If true, serves after `return next()`, allowing any downstream middleware to respond first.
 - `gzip`  Try to serve the gzipped version of a file automatically when gzip is supported by a client and if the requested file with .gz extension exists. defaults to true.
 - `br`  Try to serve the brotli version of a file automatically when brotli is supported by a client and if the requested file with .br extension exists (note, that brotli is only accepted over https). defaults to true.
 - `extensions` Try to match extensions from passed array to search for file when no extension is sufficed in URL. First found is served. (defaults to `false`)
 - [setHeaders](https://github.com/koajs/send#setheaders) Function to set custom headers on response.
