1.快速搭建 Http API服务

var HttpServer = require("../plugin/app").HttpServer;

var httpS = new HttpServer(9090, "127.0.0.1", {        filtersFunc: [            function (message) {                return true;            }        ]    }, Path.join(__dirname, "./httpServerTest"));    httpS.createServer();    httpS.on("ready", function (data) {        logger.info("Http", data);    });    httpS.on("error", function (data) {        logger.info("Http", data);    });    httpS.on("connect-connect", function (data) {        logger.info("Http", data);    });    httpS.on("connect-error", function (error) {        logger.info("Http", error);    });    httpS.on("connect-disconnect", function (data) {        logger.info("Http", data);    });    httpS.on("connect-response", function (data) {        logger.info("Http", data);    });    httpS.on("connect-errorcode", function (code) {        logger.info("Http", code);    });

说明：

自动生成 httpServerTest文件夹：

根据请求在get 或者post下面添加文件即可，支持过滤器，session,https

2.快速搭建 express web服务

基于express框架

var ExpressPlugin = require("../app");var Path = require("path");var d = new ExpressPlugin('localhost', 9095, Path.join(__dirname, "../expressTest"));d.start(function () {    console.log("ready");});d.on('uncaughtException', function (err) {    console.error('Got uncaughtException', err.stack, err);    if (d.env() == 'development') {        process.exit(1);    }});

自动生成express环境目录：

支持多层路由,例如：http://localhost:9095/user/login

3.快速搭建 热加载器服务 JadeLoader

代码中无处不在的require 和重复的require 增加了编码重复性，现在只要启动JadeLoader，即可在其他地方同种方式调用模块，同时可做简单内存（单进程，暂时不支持多进程），存储一些用户全局变量

var Path = require('path');var JadeLoader = require("../plugin/app").JadeLoader;JadeLoader.init(Path.join(__dirname, "../"), true, 60, function () {    JadeLoader.Jader('utils').get('file-utils').readAsync("c://start_nginx-php7.bat", function (err, resp) {        console.log(err, resp)    });    /**     * 测试httpclient     */var Singleton = require("./utils/app").Singleton;    var HttpClient = Singleton.getDemon(JadeLoader.Jader('utils').get('httpclient-utils'), '127.0.0.1', 9090, 2);    setInterval(function () {        HttpClient.Post("index", "zjw", function (err, resp) {            console.log("http post response:", err, resp);        });    }, 2000);});JadeLoader.on("error", function (err) {    console.error(err);});JadeLoader.on("hotLoad", function (resp) {    console.log(resp);});

说明：

JadeLoader.init 的第一个参数是让加载器接管的全局文件夹路径，它会扫描改文件夹下所有的名为：jadeContext.json 文件：

文件内容如下：

scan-dir:是否扫描当前文件夹，false则启用scan-dir-list字段，dir-name:文件夹名，app-name：文件名，hot:是否热加载

{  "scan-dir": true,  "scan-dir-list": [    {      "dir-name": "obj-utils",      "app-name": "app.js",      "hot": true    },    {      "dir-name": "singleton-utils",      "app-name": "app.js",      "hot": true    },    {      "dir-name": "time-utils",      "app-name": "app.js",      "hot": true    },    {      "dir-name": "type-utils",      "app-name": "app.js",      "hot": true    },    {      "dir-name": "timer-utils",      "app-name": "app.js",      "hot": true    }  ]}

调用方法：

JadeLoader.jader(模块所处文件夹名).get(模块文件名)

4.快速搭建 moogoose 数据库服务

地址：https://github.com/zhengjinwei123/mnode/tree/develop/mnode/mnode/utils/db-mongodb

/** * Created by 郑金玮 on 2016/12/13. */var Mongoose = require('mongoose');var Schema = Mongoose.Schema;var poolModule = require('generic-pool');var Util = require("util");var Emitter = require("events").EventEmitter;var FileUtil = require("../app").File;var Path = require("path");var _ = require("lodash");var MongodbUtil = function (host, port, db, userOption, runPath) {    Emitter.call(this);    this.host = host || '127.0.0.1';    this.port = port || 27017;    this.db = db;    this.dbUrl = null;    if (userOption == undefined) {        this.dbUrl = Util.format("mongodb://%s:%d/%s", this.host, this.port, db);    } else {        if (userOption['user'] && userOption['password']) {            this.dbUrl = Util.format("mongodb://%s:%s@%s:%d/%s", userOption.user, userOption.password, this.host, this.port, db);        }    }    if (this.dbUrl == null) {        throw new Error("args error");    }    this.runPath = runPath || Path.join(__dirname, "/schemas");    var _error = null;    try {        if (!FileUtil.isExists(this.runPath)) {            FileUtil.createDirectory(this.runPath);            var templateContent = FileUtil.readSync(Path.join(__dirname,"/template.js"));            FileUtil.writeSync(Path.join(this.runPath,"/demon.js"),templateContent);        }    } catch (e) {        _error = e.message;    } finally {        if (_error) {            console.error(_error);            process.exit(1);        }    }    var self = this;    self.connected = false;    this.pool = poolModule.Pool({        name: 'mongoose',        create: function (callback) {            var conn = Mongoose.createConnection(self.dbUrl);            conn.on('error', function (error) {                callback(error);            });            conn.once('connected', function () {                callback(null, conn);            });            conn.on('disconnected', function () {                console.error('disconnected');            });        },        destroy: function (db) {            db.close();        },        max: 20,        idleTimeoutMillis: 30000,        log: false    });    this.runList = {};    this.modelName = null;    this.loadSchema();};MongodbUtil.prototype.loadSchema = function () {    var schemaFileList = FileUtil.traverseSync(this.runPath);    var self = this;    schemaFileList.forEach(function (f) {        var scheme = require(f.path);        if (scheme['table'] && scheme['schema']) {            self.runList[scheme.table] = self.runList[scheme.table] || scheme.schema;        }    });};MongodbUtil.prototype.exec = function (callback) {    var self = this;    this.pool.acquire(function (err, client) {        var release = function () {            self.pool.release(client);        };        if (!err) {            callback(null, client, release);        } else {            release();            callback(err.stack);        }    }, 0);};MongodbUtil.prototype.schema = function (modelName) {    if (this.runList[modelName]) {        this.modelName = modelName;        return this;    } else {        throw new Error(modelName + " is not undefine");    }};MongodbUtil.prototype.model = function (callback) {    if (this.modelName == null) {        callback("please call schema method first");    } else {        var self = this;        this.exec(function (err, client, release) {            if (!err) {                callback(null, client.model(self.modelName, self.runList[self.modelName]), release);            } else {                callback(err);            }        });    }};module.exports = MongodbUtil;

template.js:

/** * Created by zhengjinwei on 2016/12/15. */var Mongoose = require('mongoose');var schemeTable = {    name: {type: String},    age: {type: Number}};var schema = new Mongoose.Schema(schemeTable, {});schema.statics.getData = function (callback) {    var condition = {};    var view = {_id: 0};    this.find(condition, view).lean().exec(function (err, docs) {        callback(err, docs);    })};schema.statics.insertData = function (callback) {    var newData = new this();    newData.name = 'zhengjinwei';    newData.age = 26;    newData.save(newData,function (err, resp) {        callback(err, resp);    })};module.exports = {    "table": 'student',    'schema': schema};

自动在指定路径下生产schema文件夹，你只要的这个文件夹下写你的数据库操作逻辑即可,look:

测试用例：

/***** * 测试用例 */var MongodbUtil = require("./app");var d = new MongodbUtil("localhost", 27017, 'mydb');d.schema('student').model(function (err, model, release) {    if (!err) {        model.getData(function (err, docs) {            console.log(err, docs);            release();        })    } else {        console.error(err);    }});d.model(function (err, model, release) {    if (!err) {        model.insertData(function (err, docs) {            console.log(err, docs);            release();        })    } else {        console.error(err);    }});

此外，还有其他各种工具类和服务，例如websocket（包括客户端，服务端），UDP(包括客户端，服务端)，
单例生成器（Singleton），redis,mysql,mongodb 连接池客户端等等
