Swagger documentation sample can be found at http://localhost:
Form input validation
Input validation is done through class-validator. The decorators are defined in src/dtos files. Two middleware can be used to process error responses.
- ../middlewares/validation.middleware
- ../middlewares/validationJsonResponse.middleware
validationJsonResponse will output the response in JSON format as given below:
{
message : null,
data: null,
errorCode : 201
errorMessages : {
"email": {
"isNotEmpty": "email should not be empty",
"isEmail": "email must be an email"
},
"password": {
"isString": "password must be a string"
}
}
}
validationMiddleware sends HTTP response. Usage of both middlewares can be seen in the routes/user.route.ts file
