|
||||
Koa static file serving middleware, wrapper for [`koa-send`](https://github.com/koajs/send).
|
||||
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
$ npm install koa-static
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
```js
|
||||
const Koa = require('koa');
|
||||
const app = new Koa();
|
||||
app.use(require('koa-static')(root, opts));
|
||||
```
|
||||
|
||||
* `root` root directory string. nothing above this root directory can be served
|
||||
* `opts` options object.
|
||||
|
||||
### 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.
|
||||
- [setHeaders](https://github.com/koajs/send#setheaders) Function to set custom headers on response.
|
||||
- `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`)
|
||||
|
||||
## Example
|
||||
|
||||
```js
|
||||
const serve = require('koa-static');
|
||||
const Koa = require('koa');
|
||||
const app = new Koa();
|
||||
|
||||
// $ GET /package.json
|
||||
app.use(serve('.'));
|
||||
|
||||
// $ GET /hello.txt
|
||||
app.use(serve('test/fixtures'));
|
||||
|
||||
// or use absolute paths
|
||||
app.use(serve(__dirname + '/test/fixtures'));
|
||||
|
||||
app.listen(3000);
|
||||
|
||||
console.log('listening on port 3000');
|
||||
```
