Adonis.js Redirector with/withErrors Session Flasher

[devhammed]

Hello everyone!

I have just ported the with and withErrors methods from Laravel Redirector.

Make sure you have enabled Async Local Storage in config/app.ts and then add this to a service provider boot method.

import { HttpContext, Redirect } from "@adonisjs/core/http";
import type { AllowedSessionValues, SessionData } from '@adonisjs/session/types';

declare module "@adonisjs/core/http" {
  export interface Redirect {
    /**
     * Flash data to the session.
     */
    with(key: string, value: AllowedSessionValues): this;
    with(data: SessionData): this;

    /**
     * Flash errors to the session.
     */
    withErrors(key: string, error: string | string[]): this;
    withErrors(errors: Record<string, string | string[]>): this;
  }
}

Redirect.prototype.with = function (
  this: Redirect,
  keyOrData: string | SessionData,
  value?: AllowedSessionValues,
) {
  const ctx = HttpContext.get();

  if (typeof keyOrData === "string") {
    ctx?.session?.flash(keyOrData, value!);
  } else {
    ctx?.session?.flash(keyOrData);
  }

  return this;
};

Redirect.prototype.withErrors = function (
  this: Redirect,
  keyOrErrors: string | Record<string, string | string[]>,
  value?: string | string[],
) {
  const ctx = HttpContext.get();

  if (typeof keyOrErrors === "string") {
    ctx?.session?.flashErrors({ [keyOrErrors]: value! });
  } else {
    ctx?.session?.flashErrors(keyOrErrors);
  }

  return this;
};

And you should now be able to do this in any route handler:

 return response
      .redirect()
      .with('success', 'Workflow deleted successfully.')
      .toRoute('workflows.index')

Happy coding!
