如何使用 serveFile 在 Deno 中提供文件？

Question

My script as follows, which compiles without errors, is suppose to serve index.html, however nothing is ever sent to the browser while the page is showing it's loading.

import { serve } from "https://deno.land/std@0.91.0/http/server.ts";
import { serveFile } from 'https://deno.land/std@0.91.0/http/file_server.ts';

const server = serve({ port: 8000 });
console.log("http://localhost:8000/");

for await (const req of server) {
  console.log(req.url);
  if(req.url === '/')
    await serveFile(req, 'index.html');
}

So why is serveFile not working in this instance?

Answer 1

The call to serveFile only creates a Response (status, headers, body) but doesn't send it.

You have to send it with a separate call to req.respond() :

import { serve } from "https://deno.land/std@0.91.0/http/server.ts";
import { serveFile } from 'https://deno.land/std@0.91.0/http/file_server.ts';

const server = serve({ port: 8000 });
console.log("http://localhost:8000/");

for await (const req of server) {
  console.log(req.url);
  if(req.url === '/') {
    const response = await serveFile(req, 'index.html');
    req.respond(response)
  }
}
