Lightweight Object Validator (lov) - lighter alternative to joi
npm install lov
Validates objects based on validation schemas. Originally designed as a lightweight replacement for the popular
Joi library (which is excellent but too heavy for use with smaller/lighter environments such as AWS Lambda).
* Programatic creation of validator objects using a fluent API
* Automatic conversion of values (strings to numbers, etc.)
* Lightweight with minimal dependencies
* Low startup overhead and quick execution
* Compatible with base Joi API
* Node.js 4.3.2 compatible
Install via npm.
npm install lov --save
It's easy to start using Lov in your project:
``js
var lov = require( 'lov' );
let schema = {
id: lov.string().uuid().trim().required(),
name: lov.string().min( 1 ).max( 100 ).required(),
age: lov.number().min( 0 ).max( 120 ),
address: lov.object().keys( {
street: lov.string().max( 60 ).required(),
street2: lov.string().max( 60 ),
city: lov.string.max( 40 ).required(),
state: lov.string().max( 20 ).required(),
postal: lov.string().max( 20 ).uppercase().required(),
country: lov.string().max( 60 ).required()
}).required(),
email: lov.string().email()
};
let value = {
id: 'f09c9ea1-114f-483a-89ef-b37d34803a79',
name: ' Fred Smith ',
age: '44',
address: {
street: '1 Yonge Street',
city: 'Toronto',
state: 'ON',
postal: 'm5e 1W7',
country: 'Canada'
},
email: 'feedback@vandium.io'
}
let result = lov.validate( value, schema );
// result.error = null
// result.value = {
//
// id: 'f09c9ea1-114f-483a-89ef-b37d34803a79',
// name: 'Fred Smith', // String trimmed
// age: 44, // '44' coverted to 44
// address: {
// street: '1 Yonge Street',
// city: 'Toronto',
// state: 'ON',
// postal: 'M5E 1W7', // Uppercase letters
// country: 'Canada'
// },
// email: 'feedback@vandium.io'
// }
