[twn39]

配置：

const indexTemplate = readFileSync(assetsPath + '/index.html', {encoding: 'utf-8'});
let compiled = Handlebars.compile(indexTemplate);

const indexHandler = async (request: FastifyRequest, reply: FastifyReply) => {
  let indexHtml = await app.ioredis.get('index.html');
  if (indexHtml == null) {
    indexHtml = compiled({env: process.env['APP_ENV']});
    await app.ioredis.setex('index.html', 300, indexHtml);
  }
  return reply.type('text/html').send(indexHtml);
}

app.get('/', indexHandler);

app.setNotFoundHandler(indexHandler);
