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]],

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

},
};
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({

}
// app/controller/user.js
exports.index = function* (ctx) {

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