v1.5.0

New tuple validation rule

Thanks for @Gamote, in this version there is a new tuple. This rule checks if a value is an Array with the elements order as described by the schema.

Example

const schema = {
    grade: { type: "tuple", items: ["string", "number", "string"] }
};

const schema = {
    location: { type: "tuple", empty: false, items: [
        { type: "number", min: 35, max: 45 },
        { type: "number", min: -75, max: -65 }
    ] }
}

Define aliases & custom rules in constructor options #162

You can define aliases & custom rules in constructor options instead of using v.alias and v.add.

Example

const v = new Validator({
    aliases: {
        username: {
            type: 'string',
            min: 4,
            max: 30
        }
    },
    customRules: {
        even: function({ schema, messages }, path, context) {
            return {
                source: `
                    if (value % 2 != 0)
                        ${this.makeError({ type: "evenNumber",  actual: "value", messages })}

                    return value;
                `
            };
        })
    }
});

Support plugins

Thanks for @erfanium, you can create plugin for fastest-validator.

Example

// Plugin Side
function myPlugin(validator){
    // you can modify validator here
    // e.g.: validator.add(...)
    // or  : validator.alias(...)
}
// Validator Side
const v = new Validator();
v.plugin(myPlugin)

Changes

• Allow empty property in string rule with pattern #149
• Add empty property to url and email rule #150
• Fix custom rule issue when multiple rules #155
