# 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:

```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. 

```json

{

    "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.
