Question

我有一个非常基本的服务器，可以通过三种方式运行：

[BLOCK 2 ENABLED] / [BLOCK 1 DISABLED]
在同一文件中定义接口，架构和模型。
[BLOCK 1 ENABLED] / [BLOCK 2 DISABLED]
在外部文件中定义接口，架构和模型： ./ models / user.ts

[BLOCK 2]的内容与文件的内容完全相同： ./ models / user.ts 。

另一方面，如果我将文件： user.ts 移至：
   ./ server / models / user.ts
  然后代码可以正常工作，但是出于某些特定原因，我需要在以下位置进行访问：
   ./ models / user.ts

以防万一，这里有存储库：

https://github.com/napolev/mongodb-experiments

代码如下：

./ server / server.ts [BLOCK 2 ENABLED]

import * as mongoose from 'mongoose';
import * as colors from 'colors';
/*/
// BLOCK 1:
import { User, IUserDocument } from '../models/user';
/*/
// BLOCK 2:
import { Document, Schema, Model, model} from "mongoose";
export interface IUser {
    username:   string,
    password:   string,
    email:      string,
    company:    string,
}
export interface IUserDocument extends IUser, Document {

}
export var UserSchema: Schema = new Schema({
    username:   String,
    password:   String,
    email:      String,
    company:    String,
});
export const User: Model<IUserDocument> = model<IUserDocument>("User", UserSchema);
//*/

mongoose.connect('mongodb://localhost:9100/mongodb-experiments');

User.find({}, function(err, users: IUserDocument[]){
    console.log(users);
});

let message = colors.green('Hello') + ' '  + colors.red.bgYellow.underline('World') + ' ' +  colors.blue.bgRed('!!!');

console.log(message);

// To work with the Mongo Shell:
// $ cd /path/to/mongodb/bin"
// $ mongo --port 9100
// use mongodb-experiments
// db.users.insert( { username: "bill.gates", password: "windows", email: "billgates@microsoft.com", company: "Microsoft" } )
// db.users.insert( { username: "steve.jobs", password: "mac", email: "stevejobs@apple.com", company: "Apple" } );
// db.getCollection("users").find()

./ models / user.ts

import { Document, Schema, Model, model} from "mongoose";

export interface IUser {
    username:   string,
    password:   string,
    email:      string,
    company:    string,
}
export interface IUserDocument extends IUser, Document {

}
export var UserSchema: Schema = new Schema({
    username:   String,
    password:   String,
    email:      String,
    company:    String,
});

export const User: Model<IUserDocument> = model<IUserDocument>("User", UserSchema);

假设我们在数据库中有一些虚拟数据：

$ cd /path/to/mongodb/bin"
$ mongo --port 9100
use mongodb-experiments
db.users.insert( { username: "bill.gates", password: "windows", email: "billgates@microsoft.com", company: "Microsoft" } )
db.users.insert( { username: "steve.jobs", password: "mac", email: "stevejobs@apple.com", company: "Apple" } );

如果我在启用[BLOCK 2]的情况下运行服务器：

$ ts-node server.ts

我得到以下输出：

Hello World !!!
[ { _id: 5b3561bbcde3135b908cb51b,
    username: 'bill.gates',
    password: 'windows',
    email: 'billgates@microsoft.com',
    company: 'Microsoft' },
  { _id: 5b3561c1cde3135b908cb51c,
    username: 'steve.jobs',
    password: 'mac',
    email: 'stevejobs@apple.com',
    company: 'Apple' } ]

但是如果我在启用[BLOCK 1]的情况下运行服务器：

我只得到以下输出：

Hello World !!!

没有以前的条目。

两种方法之间的唯一区别是接口，架构和模型的定义位置。

我做了一些实验：

如果有的话，使用上面提到的way 1和way 3：

$ cd ./server/
$ tsc server.ts
$ node server.js

然后我得到预期的输出。

但是如果有上述way 2，如果我这样做：

$ cd ./server/
$ tsc server.ts

我得到以下输出：

我认为存在冲突，因为目录./models/有自己的node_modules目录。

您认为有没有办法不包含依赖项：
{mongoose，@types/mongoose}在./server/目录上，只是在./models/目录上这样做以防止这些冲突？

关于如何使way 2工作的任何想法？

谢谢！

将模型放在另一个文件中时，MongoDB不返回任何内容
