使用 express 将 tus-node-server 集成到 feathersjs 中

Question

我有一个现有且正常工作的 Feathers 项目在最新的 feathers cli ("Buzzard") 结构中。现在我正在尝试添加 tus-node-server 作为上传服务器。正如您在 link 中找到的，他们将其设置为快速中间件的说明如下：

const tus = require('tus-node-server');
const server = new tus.Server();
server.datastore = new tus.FileStore({
    path: '/files'
});

var app = express();
const uploadApp = express();
uploadApp.all('*', server.handle.bind(server));
app.use('/uploads', uploadApp);
app.listen(port, host);

按照这些说明，我尝试将其添加到我的 app.js 文件中：

// tus node server
const tus = require('tus-node-server');
const tusServer = new tus.Server();
tusServer.datastore = new tus.FileStore({
  path: '../uploads'
});

const uploadApp = express();
uploadApp.all('*', tusServer.handle.bind(tusServer));
app.use('/uploads', uploadApp);

为了完整起见，我给出了整个 app.js 文件：

const path = require('path');
const favicon = require('serve-favicon');
const compress = require('compression');
const cors = require('cors');
const helmet = require('helmet');
const logger = require('winston');

const feathers = require('@feathersjs/feathers');
const configuration = require('@feathersjs/configuration');
const express = require('@feathersjs/express');
const socketio = require('@feathersjs/socketio');

const middleware = require('./middleware');
const services = require('./services');
const appHooks = require('./app.hooks');
const channels = require('./channels');

const sequelize = require('./sequelize');

const authentication = require('./authentication');

const app = express(feathers());

// Load app configuration
app.configure(configuration());
// Enable CORS, security, compression, favicon and body parsing
app.use(cors());
app.use(helmet());
app.use(compress());
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
app.use(favicon(path.join(app.get('public'), 'favicon.ico')));

// Host the public folder
app.use('/', express.static(app.get('public')));

// Set up Plugins and providers
app.configure(express.rest());
app.configure(socketio({
  wsEngine: 'uws',
  timeout: 120000
}));
app.configure(sequelize);

// Configure other middleware (see `middleware/index.js`)
app.configure(middleware);
app.configure(authentication);
// Set up our services (see `services/index.js`)
app.configure(services);
// Set up event channels (see channels.js)
app.configure(channels);

// tus node server
const tus = require('tus-node-server');
const tusServer = new tus.Server();
tusServer.datastore = new tus.FileStore({
  path: '../uploads'
});

const uploadApp = express();
uploadApp.all('*', tusServer.handle.bind(tusServer));
app.use('/uploads', uploadApp);

// Configure a middleware for 404s and the error handler
app.use(express.notFound());
app.use(express.errorHandler({ logger }));

app.hooks(appHooks);

module.exports = app;

我收到这个错误：

# npm start

/home/usr/api_server/node_modules/@feathersjs/express/lib/index.js:11
    throw new Error('@feathersjs/express requires a valid Feathers application instance');
    ^

    at startup (bootstrap_node.js:193:16)
    at bootstrap_node.js:617:3

应该如何设置？怎么把这个最好的融入Feathers？从 this 我得到的印象是 Services & Hooks 设置比作为中间件的设置更可取！？

作为参考，GitHub issue的解决方案是使用require('@feathersjs/express').original或require('express')来初始化应用程序：

const createExpressApp = require('express');
const uploadApp = createExpressApp();

uploadApp.all('*', tusServer.handle.bind(tusServer));
app.use('/uploads', uploadApp);

或者在您的应用中访问 require('@feathersjs/express').original（@feathersjs/express 依赖的 express 模块），如下所示：

const uploadApp = express.original();

uploadApp.all('*', tusServer.handle.bind(tusServer));
app.use('/uploads', uploadApp);

使用 express 将 tus-node-server 集成到 feathersjs 中
