Vuito example

const { Template, required, minLength } = require("vuito") function customCheck(value) { return value !== 'alreadyUsed' } const auth = new Template({ username: [ { test: required, message: 'Username is required' }, { test: minLength(3), message: 'Username must be at least 3 characters long' }, { test: customCheck, message: 'Username is already taken' }, ], // Of course you can add as much fields as you want })

// Valid username await auth.check({ username: 'michel' }) .then(() => console.log('ok')) .catch(console.error)

// Invalid username await auth.check({ username: 'alreadyUsed' }) .then(() => console.log('ok')) .catch(console.error)

// Valid username, check only username await auth.username.check('michel') .then(() => console.log('ok')) .catch(console.error)

// Invalid username, check only username await auth.username.check('alreadyUsed') .then(() => console.log('ok')) .catch(console.error)

// No username await auth.check({}) .then(() => console.log('ok')) .catch(console.error)

// Username too small, check only username await auth.username.check('12') .then(() => console.log('ok')) .catch(console.error)
