我想使用 mongodb-memory-server 和 mongoose 创建一个内存数据库。任何人都可以展示正确的方法。

Answer 1

从版本 7 及更高

版本

// this no longer works
const mongo = new MongoMemoryServer();
const uri = await mongo.getUri(); // ERROR: instance not started
// it is now
const mongo = await MongoMemoryServer.create();
const uri = mongo.getUri();

Answer 2

阅读此处的文档，并遇到了以下解决方案。

const mongoose = require('mongoose');
const { MongoMemoryServer } = require('mongodb-memory-server');
const mongoServer = new MongoMemoryServer();
mongoose.Promise = Promise;
mongoServer.getUri().then((mongoUri) => {
const mongooseOpts = {
useNewUrlParser: true,
useFindAndModify: false,
useCreateIndex: true,
useUnifiedTopology: true,
};
mongoose.connect(mongoUri, mongooseOpts);
mongoose.connection.on('error', (e) => {
console.log(e);
});
mongoose.connection.once('open', () => {
console.log(`MongoDB successfully connected to ${mongoUri}`);
});
});
module.exports=mongoose.connection;
