RunKit + 
Try any Node.js package right in your browser
This is a playground to test code. It runs a full Node.js environment and already has all of npm’s 1,000,000+ packages pre-installed, including validy. Try it out:
const validy = require('validy');
const book = { // object to validate
name: 'The Adventures of Tom Sawyer',
author: {
name: 123456 // 'Mark Twain'
},
reviews: [
{
// author: 'Leo Tolstoy',
text: 'Great novel'
},
{
author: 'Fyodor Dostoyevsky',
text: 'Very interesting'
}
]
};
const schema = {
name: {
$validate: {
required: true,
string: true
}
},
author: {
$validate: {
required: true
},
name: {
$validate: {
required: true,
string: true
}
}
},
reviews: [{ // define schema for array items
author: {
$validate: {
required: true,
string: true
}
},
text: {
$validate: {
required: true,
string: true
}
}
}]
};
validy(book, schema)
.then(errors => {
if (errors) {
// you have validation errors ("errors" is plain object)
console.log('Validation errors', errors);
} else {
// no errors ("errors" is undefined)
console.log('Everything is valid');
}
})
.catch(err => {
// application error (something went wrong)
console.log('Application error', err);
});
