Validio
A Node.js type less schema validation for model, objects and data formats. Also, Validio can run as Synchronous and as Promise implementation too, see more at Validio Npm.
How to install
npm install --save validio
How to test a specific suite
mocha -w -g "Extras arguments validating parsing extras content"
How to use it
First we need to generate the schema to validate an object where name
is a string
which max length
is 20
, and field age
is an int
which max value
is 100
:
var validio = require('validio')
validio.parse('req name 20, lastName 20, age int 100');
It will generate the next schema
{
name: {
validators: {
isString: {},
isLength: {
args: {length: 20}
}
},
required: true,
length: 20,
type: 'string'
},
lastName: {
validators: {
isString: {},
isLength: {
args: {length: 20}
}
},
length: 20,
type: 'string'
},
age: {
validators: {
isInt: {
args: {max: 100}
}
},
type: 'int'
}
}
In this case we will use the Person class, and will validate object instances using the schema:
function Person(name, email, age, phone, birth, height) {
this.name = name;
this.email = email;
this.age = age;
this.phone = phone;
this.birth = birth;
this.height = height;
};
Then we can validate the object using the schema, in this case it will validate the name
and age
because those are the only fields that appears on the schema.
var person = new Person('Joe', '[email protected]', 45);
var result = validio.validate(schema, person);
if(!result.isValid) {
console.log(result.errors.length == 1 ? 'There is an error:' : 'There are many errors:');
for(error in result.errors)
console.log(error);
}
else
console.log('Validation succeeded');
Validio as Promise
We can use Validio as Promise implementation, in the next sample we will use the same schema we build before.
var validio = require('validio').aspromise;
var schema = validio.parse('name 20, age int 100');
var person = new Person('Joe', '[email protected]', 45);
validio.validate(schema, person)
.then(function(result) {
console.log('Validation succeeded');
})
.catch(function(result) {
for(error of result.errors)
console.log(error);
});
