    🆕 New Validator configuration

    🔧 The validator has the same module configuration in broker options as other modules. It means you can configure the validation constructor options via broker options (moleculer.config.js).

    0️⃣ Default usage:

    //moleculer.config.js
module.exports = {
    nodeID: "node-100",
    validator: true // Using the default Fastest Validator
}

    Using built-in validator name:

    //moleculer.config.js
module.exports = {
    nodeID: "node-100",
    validator: "FastestValidator" // Using the Fastest Validator
}

    Example with options:

    //moleculer.config.js
module.exports = {
    nodeID: "node-100",
    validator: {
        type: "FastestValidator",
        options: {
            useNewCustomCheckerFunction: true,
            defaults: { /*...*/ },
            messages: { /*...*/ },
            aliases: { /*...*/ }
        }
    }
}

    Example with custom validator

    //moleculer.config.js
const BaseValidator = require("moleculer").Validators.Base;

class MyValidator extends BaseValidator {}

module.exports = {
    nodeID: "node-100",
    validator: new MyValidator()
}
