typescript-crud-example

Basic CRUD server using TypeScript, class-validator, mybatis-mapper.

Usage

1. git clone ~
2. import sql file in db directory
3. change the .env
4. npm i
5. npm start

※ if MODULE_NOT_FOUND happens then go back to 5(You will do it only one time after clone this)

Note

Why MODULE_NOT_FOUND error can be occured

package.json:

...
  "scripts": {
    "start": "concurrently \"tsc -w\" \"nodemon dist/app\"",
    "test": "echo \"Error: no test specified\" && exit 1"
  },
...

concurrently \"tsc -w\" \"nodemon dist/app\"

concurrently executes the command (almost) at the same time.

So tsc -w and nodemon dist/app will be executed simultaneously, it can be happen that

nodemon dist/app can be executed before tsc -w is executed.

Test with Postman

BODY should be raw-json type.

{
    "name": "John",
    "age": 44,
    "job": "Freeloader"
}

For the sake of class-validation. If you don't send the request with raw-json, validation will be failed because all integers which is supposed to be integer send as string.
