serve-tpl-attachment
==================
```js
var serveIndex = require('serve-index')({
template: require('serve-tpl-attachment')()
});
```
A fork of the original `serve-index` template that, in combination with `serve-static`,
provides support for direct file downloads (using the Content-Disposition attachment header).
### Example Usage
```js
var serveTpl = require('serve-tpl-attachment');
var serveIndex = require('serve-index')('./public', { template: serveTpl() });
app.use('/', function (req, res, next) {
// enable direct downloads for express.static()
if (req.query.download) {
res.setHeader('Content-Type', 'application/octet-stream');
res.setHeader('Content-Disposition', 'attachment; filename="'+
path.basename(req.url.replace(/\?.*/, ''))
+'"');
}
next();
}, express.static('./public'), serveIndex);
```
Additional Options
==================
### privatefiles
As an additional security precaution you can ignore files which are not world-readable.
For example, this would prevent files in a `~/.ssh` from being read even when `dotfiles` are allowed.
`{ privatefiles: 'ignore' }`
```js
var serveTpl = require('serve-tpl-attachment');
var serveTemplate = serveTpl({ privatefiles: 'ignore' })
```
This is most effective on Unix-based systems (macOS, Linux, Android).
Windows may rely on ACLs instead of user-group-other style permissions.
