  • Check if a file exists
  • Set content-length, content-type, and last-modified headers
  • 304 based on last-modified
  • Handle HEAD requests

  • Check for malicious paths or hidden files
  • Support directory indexes
  • Cache control

API

sendfile(context, filename)

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 if (context.status).

const sendfile = require('koa-sendfile')

app.use(async function (ctx, next) {
  const stats = await sendfile(ctx, '/Users/jong/.bash_profile')
  if (!ctx.status) ctx.throw(404)
})
