带有 ts 的 nodeJS : 模块在本地声明组件，但不导出

Question

在我的 nodeJS 应用程序中，我有一个 models 和 seeders 文件夹，我创建了一个这样的 address.model.ts 模式：

export {};
const mongoose = require('mongoose');

const addressSchema = new mongoose.Schema({
  street: {
    type: String,
    required: true,
  },
  number: {
    type: String,
    required: true,
  },
  city: {
    type: String,
    required: true,
  },
  codePostal: { type: mongoose.Schema.Types.ObjectId, ref: 'codePostal'  },
  country: {
    type: String,
    required: true,
  },
  longitude: {
    type: Number,
    required: false,
  },
  latitude: {
    type: Number,
    required: false,
  }
});

const ALLOWED_FIELDS = ['id', 'street', 'number','city', 'codePostal', 'country'];


/**
 * @typedef Address
 */
const Address = mongoose.model('Address', addressSchema);
Address.ALLOWED_FIELDS = ALLOWED_FIELDS;
module.exports = Address;

和 addresses.ts 这样的种子：

import faker from 'faker'
import {
  Address
} from '../src/api/models/address.model'

export const seedAdresses = async () => {
  try {
    const quantity = 10
    const adresses = []

    for (let i = 0; i < quantity; i++) {
      adresses.push(
        new Address({
          street   : faker.address.streetName(),
          number   : faker.address.streetAddress(),
          city     : faker.address.city(),
          country  : faker.address.country(),
          longitude: faker.address.longitude(),
          latitude : faker.address.latitude(),

        })
      )
    }

  } catch (err) {
    console.log(err);
  }
}

seedAdresses()

导入地址时出错：

module '"../src/api/models/address.model"' declare 'Address' locally, but it is not exported. I don't understand why it's not exported although module.exports = Address; exist in my schema!

Answer 1

问题是您正在使用 ES6 imports/exports 的 CommonJS 导出，在 address.model.ts 中使用 export { Address }; 而不是 export {};。

您还应该考虑使用 import { Schema, model } from "mongoose" 以与 ES6 保持一致。
