Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

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
}

    options: {
      mongos: true,
    },
