输入net start mysql或sc start mysql

启动mysql服务

ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘123456’;

nest generate controller messages/messages –flat 不会产生新的文件夹

执行的时候都会变为js，那么类型就不存在了。那这是怎么做到的呢？

所以并不是所有的ts都不会被编译到js里面

后面发现需要的话就会重用实例

database

user resource

save和remove就是为instance设计的

更新的逻辑，效率有点低

大项目

小项目

以后的发展

https://www.notion.so

因此需要创建拦截器

https://www.notion.so

e2e测试跳过了main.ts file

换成下面的这种

以便让e2e运行pipe和cookie-session

多数据库

需要注意并行运行e2e测试，并行访问sqlite文件会报错，因此改为串行--maxWorkers=1

onetomany 数据库没有改变，Manytone，数据库有改变

验证和授权

需要转换为middleware

typeorm cli中不能获取到connection options

没有能力读取json、yml格式的文件
不应该用ts，因为直接运行的是js,其实现在已经可以了
不能利用环境变量来设置类型

测试的时候使用这个执行的，会报错

dev—js

test—ts

npm install -g ts-node
