Installation

NPM

You can install it via NPM.

$ npm i fastest-validator --save

or

$ yarn add fastest-validator

Usage

Validate

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.

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

const v = new Validator();

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

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

Try it on Repl.it

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

Deno usage

With esm.sh, now Typescript is supported

import FastestValidator from "https://esm.sh/[email protected]"

const v = new FastestValidator();
const check = v.compile({
	name: "string",
	age: "number",
});

console.log(check({ name: "Erf", age: 18 })); //true

Supported frameworks

• Moleculer: Natively supported
• Fastify: By using fastify-fv

Optional, Required & Nullable fields

Optional

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

Nullable

If you want disallow undefined value but allow null value, use nullable instead of optional.

const schema = {
    age: { type: "number", nullable: true }
}

v.validate({ age: 42 }, schema); // Valid
v.validate({ age: null }, schema); // Valid
v.validate({ age: undefined }, schema); // Fail because undefined is disallowed
v.validate({}, schema); // Fail because undefined is disallowed

Strict validation

Object properties which are not specified on the schema are ignored by default. If you set the $$strict option to true any additional 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 sanitizers. 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.

Static 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
}
*/

Dynamic Default value: Also you can use dynamic default value by defining a function that returns a value. For example, in the following code, if createdAt field not defined in object`, the validator sets the current time into the property:

const schema = {
    createdAt: {
        type: "date",
        default: () => new Date()
    }
};

const obj = {}

v.validate(obj, schema); // Valid
console.log(obj);
/*
{
    createdAt: Date(2020-07-25T13:17:41.052Z)
}
*/

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
}

Array of X

const schema = {
    foo: "string[]" // means array of string
}

check({ foo: ["bar"] }) // true

Nested objects

const schema = {
   dot: {
      $$type: "object",
      x: "number",  // object props here
      y: "number",  // object props here
   }, 
   circle: {
      $$type: "object|optional", // using other shorthands
      o: {
         $$type: "object",
         x: "number",
         y: "number",
      },
      r: "number"
   }
};

Alias definition

You can define custom aliases.

v.alias('username', {
    type: 'string',
    min: 4,
    max: 30
    // ...
});

const schema = {
    username: "username|max:100", // Using the 'username' alias
    password: "string|min:6",
}

Default options

You can set default rule options.

var v = new FastestValidator({
    defaults: {
        object: {
            strict: "remove"
        }
    }
});

Built-in validators

any

This does not do type validation. Accepts any types.

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

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

array

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

Example for unique:

const schema = {
    roles: { type: "array", unique: true }
}

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

    grade: { type: "tuple", items: ["string", "number"] }
}

v.validate({ grade: ["David", 85] }, schema); // Valid
v.validate({ grade: [85, "David"] }, schema); // Fail (wrong position)
v.validate({ grade: ["Cami"] }, schema); // Fail (require 2 elements)

Example with a more detailed schema:

v.validate({ url: "www.facebook.com" }, schema); // Fail

Properties

uuid

This is an UUID validator.

const schema = {
    uuid: { type: "uuid" }
}

v.validate({ uuid: "00000000-0000-0000-0000-000000000000" }, schema); // Valid Nil UUID
v.validate({ uuid: "10ba038e-48da-487b-96e8-8d3b99b6d18a" }, schema); // Valid UUIDv4

Properties

objectID

You can validate BSON/MongoDB ObjectID's

const  { ObjectID } = require("mongodb") // or anywhere else 

const schema = {
    id: {
        type: "objectID",
        ObjectID // passing the ObjectID class
    }  
}

const check = v.compile(schema);
check({ id: "5f082780b00cc7401fb8e8fc" }) // ok
check({ id: new ObjectID() }) // ok
check({ id: "5f082780b00cc7401fb8e8" }) // Error

Pro tip: By using defaults props for objectID rule, No longer needed to pass ObjectID class in validation schema:

const  { ObjectID } = require("mongodb") // or anywhere else 

const v = new Validator({
    defaults: {
        objectID: {
            ObjectID
        }
    }
})

const schema = {
    id: "objectID" 
}

Properties

You can also create your custom validator.

const 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:

const v = new Validator({
    useNewCustomCheckerFunction: true, // using new version
    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, errors, schema) {
            if (value < minWeight) errors.push({ type: "weightMin", expected: schema.minWeight, actual: value });
            if (value > 100) value = 100
            return value
        }
    }
};

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'
    }]
*/
const o = { name: "John", weight: 110 }
console.log(v.validate(o, schema));
/* Returns: true
   o.weight is 100
*/

Please note: the custom function must return the value. It means you can also sanitize it.

Custom validation for built-in rules

You can define a custom function in the schema for built-in rules. With it you can extend any built-in rules.

const v = new Validator({
    useNewCustomCheckerFunction: true, // using new version
    messages: {
        // Register our new error message text
        phoneNumber: "The phone number must be started with '+'!"
    }
});

const schema = {
    name: { type: "string", min: 3, max: 255 },
    phone: { type: "string", length: 15, custom: (v, errors) => {
            if (!v.startsWith("+")) errors.push({ type: "phoneNumber" })
            return v.replace(/[^\d+]/g, ""); // Sanitize: remove all special chars except numbers
        }
    }	
};

console.log(v.validate({ name: "John", phone: "+36-70-123-4567" }, schema));
// Returns: true

console.log(v.validate({ name: "John", phone: "36-70-123-4567" }, schema));
/* Returns an array with errors:
    [{
        message: "The phone number must be started with '+'!",
        field: 'phone',
        type: 'phoneNumber'
    }]
*/

Please note: the custom function must return the value. It means you can also sanitize it.

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 customize 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"
        }
    }
}
v.validate({ firstname: "John", lastname: 23 }, schema );
/* Returns:
[
    {
        type: 'stringMin',
        expected: 6,
        actual: 4,
        field: 'firstname',
        message: 'Your firstname is too short'
    },
    {
        type: 'string',
        expected: undefined,
        actual: undefined,
        field: 'lastname',
        message: 'Please check your lastname'
    }
]
*/

Plugins

You can apply plugins:

// Plugin Side
function myPlugin(validator){
    // you can modify validator here
    // e.g.: validator.add(...)
}

// Validator Side
const v = new Validator();
v.plugin(myPlugin)
