    image: mongo:3

    ports:

    - "27017:27017"

项目初始化

yarn  init -y

添加依赖

yarn add @graphql-mesh/cli @graphql-mesh/mongoose @graphql-mesh/runtime graphql mongoose ts-node 

yarn add @types/mongoose @types/node typescript --dev

package.json

启动mongo 服务

docker-compose up -d 

集成使用

.meshrc.yml 文件

require:

  - ts-node/register/transpile-only

sources:

  - name: Mongoose

    handler:

      mongoose:

        connectionString: mongodb://localhost:27017/test

        models:

          - name: User

            path: ./src/models.ts#User

模型定义
src/models.ts

 
import { Schema, model } from 'mongoose';

​

const LanguagesSchema = new Schema(

  {

    language: String,

    skill: {

      type: String,

      enum: ['basic', 'fluent', 'native'],

    },

  },

  {

    _id: false, // disable `_id` field for `Language` schema

  }

);

​

const AddressSchema = new Schema({

  street: String,

  geo: {

    type: [Number], // [<longitude>, <latitude>]

    index: '2dsphere', // create the geospatial index

  },

});

​

export const UserSchema = new Schema(

  {

    name: {

      type: String,

      index: true,

    },

    age: {

      type: Number,

      index: true,

    },

    languages: {

      type: [LanguagesSchema], // you may include other schemas (also as array of embedded documents)

      default: [],

    },

    contacts: {

      // another mongoose way for providing embedded documents

      email: String,

      phones: [String], // array of strings

    },

    gender: {

      // enum field with values

      type: String,

      enum: ['male', 'female', 'ladyboy'],

    },

    address: {

      type: AddressSchema,

    },

    someMixed: {

      type: Schema.Types.Mixed,

      description: 'Some dynamic data',

    },

    salaryDecimal: {

      type: Schema.Types.Decimal128,

      index: true,

    },

  },

  {

    collection: 'user_users',

  }

);

​

UserSchema.index({ gender: 1, age: -1 });

​

export const User = model('User', UserSchema);
