Check if a file exists

[Hunam6]

I would like to do something like this:

app.use(async ctx => {
  if (await send(ctx, ctx.request.url.pathname, {root: './assets'}) != undefined) await send(ctx, ctx.request.url.pathname, {root: './assets'})
  else ctx.response.body = '404'
})

Any idea?

Sorry my bad, nothing to do with Oak, just use fs.
If anyone intrested:

import {exists} from 'https://deno.land/std/fs/mod.ts'
app.use(async ctx => {
  if (await exists('./assets' + ctx.request.url.pathname)) await send(ctx, ctx.request.url.pathname, {root: './assets'})
  else {
    ctx.response.body = 'error 404'
    ctx.response.status = 404
  }
})
