Installation

NPM

You can install it via NPM.

$ npm i fastest-validator --save

or

$ yarn add fastest-validator

Usage

Simple method

Call the validate method with the object and the schema.

If performance is important, you won't use this method because it's slow.

let Validator = require("fastest-validator");

let v = new Validator();

const schema = {
    id: { type: "number", positive: true, integer: true },
    name: { type: "string", min: 3, max: 255 },
    status: "boolean" // short-hand def
};

console.log(v.validate({ id: 5, name: "John", status: true }, schema));
// Returns: true

console.log(v.validate({ id: 5, name: "Al", status: true }, schema));
/* Returns an array with errors:
    [
        {
            type: 'stringMin',
            expected: 3,
            actual: 2,
            field: 'name',
            message: 'The \'name\' field length must be greater than or equal to 3 characters long!'
        }
    ]
*/

Fast method

In this case, the first step is to compile the schema to a compiled "checker" function. After that, to validate your object, just call this "checker" function.

This method is the fastest.

let Validator = require("fastest-validator");

let v = new Validator();

var schema = {
    id: { type: "number", positive: true, integer: true },
    name: { type: "string", min: 3, max: 255 },
    status: "boolean" // short-hand def
};

var check = v.compile(schema);

console.log(check({ id: 5, name: "John", status: true }));
// Returns: true

console.log(check({ id: 2, name: "Adam" }));
/* Returns an array with errors:
    [
        {
            type: 'required',
            field: 'status',
            message: 'The \'status\' field is required!'
        }
    ]
*/

Browser usage

<script src="https://unpkg.com/fastest-validator"></script>

var v = new FastestValidator();

const schema = {
    id: { type: "number", positive: true, integer: true },
    name: { type: "string", min: 3, max: 255 },
    status: "boolean" // short-hand def
};

const check = v.compile(schema);

console.log(check({ id: 5, name: "John", status: true }));
// Returns: true

Optional & required fields

Every field in the schema will be required by default. If you'd like to define optional fields, set optional: true.

const schema = {
    name: { type: "string" }, // required
    age: { type: "number", optional: true }
}

v.validate({ name: "John", age: 42 }, schema); // Valid
v.validate({ name: "John" }, schema); // Valid
v.validate({ age: 42 }, schema); // Fail because name is required

Strict validation

Object properties which are not specified on the schema are ignored by default. If you set the $$strict option to true any aditional properties will result in an strictObject error.

const schema = {
    name: { type: "string" }, // required
    $$strict: true // no additional properties allowed
}

v.validate({ name: "John" }, schema); // Valid
v.validate({ name: "John", age: 42 }, schema); // Fail

Remove additional fields

To remove the additional fields in the object, set $$strict: "remove".

Multiple validators

It is possible to define more validators for a field. In this case, only one validator needs to succeed for the field to be valid.

const schema = {
    cache: [
        { type: "string" },
        { type: "boolean" }
    ]
}

v.validate({ cache: true }, schema); // Valid
v.validate({ cache: "redis://" }, schema); // Valid
v.validate({ cache: 150 }, schema); // Fail

Root element schema

Basically the validator expects that you want to validate a Javascript object. If you want others, you can define the root level schema, as well. In this case set the $$root: true property.

Example to validate a string variable instead of object

const schema = {
    $$root: true,
    type: "string", 
    min: 3, 
    max: 6
};

v.validate("John", schema); // Valid
v.validate("Al", schema); // Fail, too short.

Sanitizations

The library contains several sanitizaters. Please note, the sanitizers change the original checked object.

Default values

The most common sanitizer is the default property. With it, you can define a default value for all properties. If the property value is null or undefined, the validator set the defined default value into the property.

Default value example:

const schema = {
    roles: { type: "array", items: "string", default: ["user"] },
    status: { type: "boolean", default: true },
};

const obj = {}

v.validate(obj, schema); // Valid
console.log(obj);
/*
{
    roles: ["user"],
    status: true
}
*/

Shorthand definitions

You can use string-based shorthand validation definitions in the schema.

const schema = {
    password: "string|min:6",
    age: "number|optional|integer|positive|min:0|max:99", // additional properties
    state: ["boolean", "number|min:0|max:1"] // multiple types
}

Built-in validators

any

This does not do type validation. Accepts any types.

const schema = {
    prop: { type: "any" }
}

v.validate({ prop: true }, schema); // Valid
v.validate({ prop: 100 }, schema); // Valid
v.validate({ prop: "John" }, schema); // Valid

array

This is an Array validator.

Simple example with strings:

const schema = {
    roles: { type: "array", items: "string" }
}

v.validate({ roles: ["user"] }, schema); // Valid
v.validate({ roles: [] }, schema); // Valid
v.validate({ roles: "user" }, schema); // Fail

Example with only positive numbers:

const schema = {
    list: { type: "array", min: 2, items: {
        type: "number", positive: true, integer: true
    } }
}

v.validate({ list: [2, 4] }, schema); // Valid
v.validate({ list: [1, 5, 8] }, schema); // Valid
v.validate({ list: [1] }, schema); // Fail (min 2 elements)
v.validate({ list: [1, -7] }, schema); // Fail (negative number)

Example with an object list:

const schema = {
    users: { type: "array", items: {
        type: "object", props: {
            id: { type: "number", positive: true },
            name: { type: "string", empty: false },
            status: "boolean"
        }
    } }
}

v.validate({
    users: [
        { id: 1, name: "John", status: true },
        { id: 2, name: "Jane", status: true },
        { id: 3, name: "Bill", status: false }
    ]
}, schema); // Valid

Example for enum:

const schema = {
    roles: { type: "array", items: "string", enum: [ "user", "admin" ] }
}

v.validate({ roles: ["user"] }, schema); // Valid
v.validate({ roles: ["user", "admin"] }, schema); // Valid
v.validate({ roles: ["guest"] }, schema); // Fail

Properties

Property	Default	Description

Custom validator

You can also create your custom validator.

let v = new Validator({
    messages: {
        // Register our new error message text
        evenNumber: "The '{field}' field must be an even number! Actual: {actual}"
    }
});

// Register a custom 'even' validator
v.add("even", function({ schema, messages }, path, context) {
    return {
        source: `
            if (value % 2 != 0)
                ${this.makeError({ type: "evenNumber",  actual: "value", messages })}

            return value;
        `
    };
});

const schema = {
    name: { type: "string", min: 3, max: 255 },
    age: { type: "even" }
};

console.log(v.validate({ name: "John", age: 20 }, schema));
// Returns: true

console.log(v.validate({ name: "John", age: 19 }, schema));
/* Returns an array with errors:
    [{
        type: 'evenNumber',
        expected: null,
        actual: 19,
        field: 'age',
        message: 'The \'age\' field must be an even number! Actual: 19'
    }]
*/

Or you can use the custom type with an inline checker function:

let v = new Validator({
    messages: {
        // Register our new error message text
        weightMin: "The weight must be greater than {expected}! Actual: {actual}"
    }
});

const schema = {
    name: { type: "string", min: 3, max: 255 },
    weight: {
        type: "custom",
        minWeight: 10,
        check(value, schema) {
            return (value < schema.minWeight)
                ? this.makeError("weightMin", schema.minWeight, value)
                : true;
        }
    }
};

console.log(v.validate({ name: "John", weight: 50 }, schema));
// Returns: true

console.log(v.validate({ name: "John", weight: 8 }, schema));
/* Returns an array with errors:
    [{
        type: 'weightMin',
        expected: 10,
        actual: 8,
        field: 'weight',
        message: 'The weight must be greater than 10! Actual: 8'
    }]
*/

Custom error messages (l10n)

You can set your custom messages in the validator constructor.

const Validator = require("fastest-validator");
const v = new Validator({
    messages: {
        stringMin: "A(z) '{field}' mező túl rövid. Minimum: {expected}, Jelenleg: {actual}",
        stringMax: "A(z) '{field}' mező túl hosszú. Minimum: {expected}, Jelenleg: {actual}"
    }
});

v.validate({ name: "John" }, { name: { type: "string", min: 6 }});
/* Returns:
[
    {
        type: 'stringMin',
        expected: 6,
        actual: 4,
        field: 'name',
        message: 'A(z) \'name\' mező túl rövid. Minimum: 6, Jelenleg: 4'
    }
]
*/

Personalised Messages

Sometimes the standard messages are too generic. You can customise messages per validation type per field:

const Validator = require("fastest-validator");
const v = new Validator();
const schema = {
    firstname: {
        type: "string",
        min: 6,
        messages: {
            string: "Please check your firstname",
            stringMin: "Your firstname is too short"
        }
    },
    lastname: {
        type: "string",
        min: 6,
        messages: {
            string: "Please check your lastname",
            stringMin: "Your lastname is too short"
        }
