class-validator-ext
npm install class-validator-extclass validator returns errors like this
``
[{
target: / post object /,
property: "title",
value: "Hello",
constraints: {
length: "$property must be longer than or equal to 10 characters"
}
}, {
target: / post object /,
property: "text",
value: "this is a great post about hell world",
constraints: {
contains: "text must contain a hello string"
}
}]
which is hard to use, this library simplifies it to be a key:value pair of errors
`
yarn add class-validator-extension
`
import { IsNotEmpty } from 'class-validator';
import * as classValidatorExt from 'class-validator-ext';
class User {
@IsNotEmpty()
@IsEmail()
email: string;
@IsNotEmpty()
password: string;
}
(async () => {
const user = new User();
const errors = await classValidatorExt.validateAndExtract(user);
console.log(errors);
})();
`
This will return key: value errors
Invalid
`
{
isValid: false,
errors: {
"email": "email should not be empty",
"password": "password should not be empty"
}
}
Valid
`
{
isValid: true,
errors: { }
}
