Daruk Middleware

Daruk Middleware click

import { Daruk, defineMiddleware, MiddlewareClass } from "daruk";
import { parameter } from "daruk-validate";

@defineMiddleware("daruk-validate")
class DarukValidate implements MiddlewareClass {
  public initMiddleware(daruk: Daruk) {
    // If there is no global error intercept
    // You can use this middleware to catch errors
    return parameter(daruk.app);
  }
}

Translate

You can override the translate method of parameter to implement I18n, by passing a function like this :

import { Daruk, defineMiddleware, MiddlewareClass } from "daruk";
import { parameter } from "daruk-validate";

@defineMiddleware("daruk-validate")
class DarukValidate implements MiddlewareClass {
  public initMiddleware(daruk: Daruk) {
    parameter(daruk.app, function() {
      // Same example with node-parameter
      var args = Array.prototype.slice.call(arguments);
      // Assume there have I18n.t method for convert language.
      return I18n.t.apply(I18n, args);
    }});
  }
}

Error

import { Daruk, defineMiddleware, MiddlewareClass } from "daruk";
import { errorVerify } from "daruk-validate";

@defineMiddleware("error")
class DarukValidate implements MiddlewareClass {
  public initMiddleware(daruk: Daruk) {
    // Create a global capture middleware
    return errorVerify;
  }
}
