Question

我们有一个大型应用程序，它使用express来进行休息，使用primus进行套接字路由。立即将所有内容转换为羽毛非常困难。我正在考虑一种分阶段的方法，在该方法中，我可以采取一些路线并将其转换为服务，并且导致任何新路线都将遵循服务模式。我将慢慢迁移应用程序的其余部分。

客户端目前正在使用primus和angularjs $ http与nodejs进行通信。

我们当前的设置如下

var http = require('http');
var express = require('express');
var bodyParser = require('body-parser');
var cookieParser = require('cookie-parser');
const csrf = require('csurf');

var Primus = require('primus');
var SocketService = require('./../services/socket-service'); ////this handles existing socket routes from primus client using spark.write

var routesUtils = require('../utilities/routes-utility');
var _ = require('lodash');

module.exports = function(isClusteredDeploy) {
    var app = express();
    var server = http.createServer(app);
    var primus = new Primus(server, {transformer: 'uws'});
    var socketService = SocketService(primus); 
    var commonSocketRoute, commonRoute;

    //primus.library();
    //primus.save(__dirname + '/primus-client.js');

    app.use(bodyParser.urlencoded({
        extended: true
    }));

    app.use(bodyParser.json({
        strict: false,
        limit: '1mb'
    }));

    app.use(cookieParser());

    app.use(csrf({ cookie: true }));
    app.use(function (err, req, res, next) {
        if (err.code !== 'EBADCSRFTOKEN') {
            return next(err);
        }

        res.status(403);
        res.send();
    });
    app.use(function(req, res, next) {
        res.cookie('XSRF-TOKEN', req.csrfToken());
        next();
    });

    server.listen(config.get(constants.CONFIG_App_Port), function() {
        log.info('App server ==> %s is listening on port %d', config.get('rest_host_config.' + config.get('app_key') + '.host'),
            config.get(constants.CONFIG_App_Port));
    });

    //dynamically loading rest routes and socket routes from the file system
    var files = routesUtils.readRoutes(true);
    files.forEach(function(file) {
        if (_.includes(file, 'socket')) {
            commonSocketRoute = require('./../../' + file);
            commonSocketRoute(socketService);
        } else {
            commonRoute = require('./../../' + file);
            commonRoute(app);
        }
    });
};

我想在其中添加羽毛，然后慢慢开始转换。这可能吗？

是的，通过标准的register services框架集成，您的Feathers应用程序也将是完全兼容Express的应用程序，并且还允许@feathersjs/primus。

在您的情况下，您可以将var app = express();替换为：

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

// Create an app that is a Feathers AND Express application
const app = express(feathers());

// Set up REST services (optional)
app.configure(express.rest());

一切应该继续正常进行。下一步将使用blog框架适配器替换自定义Primus代码：

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

// Create an app that is a Feathers AND Express application
const app = express(feathers());

// Set up Primus with SockJS
app.configure(primus({ transformer: 'ws' }));

现在，您还可以将http.createServer设置替换为更简单的

const server = app.listen(config.get(constants.CONFIG_App_Port))

因为Feathers将处理所有Express和Primus初始化。 Primus实例将以app.primus的形式提供。
