Egg's mongoose plus. 允许eggjs项目中同时使用sequelize 和mongoose 的数据库服务

Install

$ npm i egg-mongoose-plus --save

Configuration

Change {app_root}/config/plugin.js to enable egg-mongoose plugin:

exports.mongoose = {
  enable: true,
  package: 'egg-mongoose-plus',
};

Simple connection

Config

// {app_root}/config/config.default.js
exports.mongoose = {
  url: 'mongodb://127.0.0.1/example',
  options: {},
  // mongoose global plugins, expected a function or an array of function and options
  plugins: [createdPlugin, [updatedPlugin, pluginOptions]],
  model: {
    loadModel: true, //是否自动加载模型文件

    //当需要与sequelize同时使用时,必须修改下方两项配置,否则会与sequelize不兼容,而报错
    name: "mongoModel", //加载的模型文件挂载到app对象的属性名,默认是model,如果想与sequelize同时使用,最好单独定义一个名字(sequelize默认挂载app属性名就是model)
    path: "app/mongodb" //模型文件路径,相对于项目跟目录的路径,默认是app/model,如果想与sequelize同时使用,最好单独定义一个路径(sequelize默认模型路径就是app/model)
  },
};
// recommended
exports.mongoose = {
  client: {
    url: 'mongodb://127.0.0.1/example',
    options: {},
    // mongoose global plugins, expected a function or an array of function and options
    plugins: [createdPlugin, [updatedPlugin, pluginOptions]],
    model: {
      loadModel: true, //是否自动加载模型文件

      //当需要与sequelize同时使用时,必须修改下方两项配置,否则会与sequelize不兼容,而报错
      name: "mongoModel", //加载的模型文件挂载到app对象的属性名,默认是model,如果想与sequelize同时使用,最好单独定义一个名字(sequelize默认挂载app属性名就是model)
      path: "app/mongodb" //模型文件路径,相对于项目跟目录的路径,默认是app/model,如果想与sequelize同时使用,最好单独定义一个路径(sequelize默认模型路径就是app/model)
    },
  },
};

Example

// {app_root}/app/mongodb/user.js
module.exports = app => {
  const mongoose = app.mongoose;
  const Schema = mongoose.Schema;

  const UserSchema = new Schema({
    userName: { type: String  },
    password: { type: String  },
  });

  return mongoose.model('User', UserSchema);
}

// {app_root}/app/controller/user.js
exports.index = function* (ctx) {
  ctx.body = yield this.app.mongoModel.User.find({});
}

Multiple connections

Config

// {app_root}/config/config.default.js
exports.mongoose = {
  clients: {
    // clientId, access the client instance by app.mongooseDB.get('clientId')
    db1: {
      url: 'mongodb://127.0.0.1/example1',
      options: {},
      // client scope plugin array
      plugins: []
    },
    db2: {
      url: 'mongodb://127.0.0.1/example2',
      options: {},
    },
  },
  // public scope plugin array
  plugins: [],
  model: {
    loadModel: true, //是否自动加载模型文件

    //当需要与sequelize同时使用时,必须修改下方两项配置,否则会与sequelize不兼容,而报错
    name: "mongoModel", //加载的模型文件挂载到app对象的属性名,默认是model,如果想与sequelize同时使用,最好单独定义一个名字(sequelize默认挂载app属性名就是model)
    path: "app/mongodb" //模型文件路径,相对于项目跟目录的路径,默认是app/model,如果想与sequelize同时使用,最好单独定义一个路径(sequelize默认模型路径就是app/model)
  },
};

Example

// {app_root}/app/mongodb/user.js
module.exports = app => {
  const mongoose = app.mongoose;
  const Schema = mongoose.Schema;
  const conn = app.mongooseDB.get('db1'); 

  const UserSchema = new Schema({
    userName: { type: String },
    password: { type: String },
  });

  return conn.model('User', UserSchema);
}

// {app_root}/app/mongodb/book.js
module.exports = app => {
  const mongoose = app.mongoose;
  const Schema = mongoose.Schema;
  const conn = app.mongooseDB.get('db2');

  const BookSchema = new Schema({
    name: { type: String },
  });

  return conn.model('Book', BookSchema);
}

// app/controller/user.js
exports.index = function* (ctx) {
  ctx.body = yield this.app.mongoModel.User.find({}); // get data from db1
}

// app/controller/book.js
exports.index = function* (ctx) {
  ctx.body = yield this.app.mongoModel.Book.find({}); // get data from db2
}

Default config

see config/config.default.js for more detail.

Multi-mongos support

// {app_root}/config/config.default.js
exports.mongoose = {
  client: {
    url: 'mongodb://mongosA:27501,mongosB:27501',
    options: {
      mongos: true,
    },
    model: {
      loadModel: true, //是否自动加载模型文件

      //当需要与sequelize同时使用时,必须修改下方两项配置,否则会与sequelize不兼容,而报错
      name: "mongoModel", //加载的模型文件挂载到app对象的属性名,默认是model,如果想与sequelize同时使用,最好单独定义一个名字(sequelize默认挂载app属性名就是model)
      path: "app/mongodb" //模型文件路径,相对于项目跟目录的路径,默认是app/model,如果想与sequelize同时使用,最好单独定义一个路径(sequelize默认模型路径就是app/model)
