Basic file-sending utility for koa. It does the following:
- Check if a file exists
- Set content-length, content-type, and last-modified headers
- 304 based on last-modified
- Handle HEAD requests
It does not:
- Check for malicious paths or hidden files
- Support directory indexes
- Cache control
- OPTIONS method
You must pass the koa context.
filename is the filename of the file.
sendfile returns a promise that resolves to the
fs.stat() result of the filename. If sendfile() resolves, that doesn't mean that a response is set - the filename could be a directory. Instead, check
var sendfile =app
