Do you have an updated 'bootstrap-form-renderer.js' to work with the new validation release?

@VagyokC4 create validation rules as view-model's property:

  rules = ValidationRules
    .ensure('firstName')
      .minLength(12)
      .maxLength(12)
      .required()
    .rules;

and then use them in view:

<input type="email" class="form-control" id="email" placeholder="Email"  value.bind="email & validate:rules">

Do you have an updated bootstrap-form-renderer compatible with bootstrap 4.0.0 where they completely revamped the form classes and added compatibility for HTML5 :invalid and :valid pseudo-classes? Completely at a loss here.

@cornillemichiel I have bootstrap 4 beta 2 and it has support for is-invalid class along :invalid selector.
so here's an adjusted source

import { ValidationController } from 'aurelia-validation';
import { Container } from 'aurelia-dependency-injection';
import { ValidationControllerFactory } from 'aurelia-validation';
import {
    ValidationRenderer,
    RenderInstruction,
    ValidateResult
  } from 'aurelia-validation';
  
  export class BootstrapFormRenderer {
    render(instruction: RenderInstruction) {
      
      for (let { result, elements } of instruction.unrender) {
        for (let element of elements) {
          this.remove(element, result);
        }
      }
  
      for (let { result, elements } of instruction.render) {
        for (let element of elements) {
          this.add(element, result);
        }
      }
    }
  
    add(element: Element, result: ValidateResult) {
      if (result.valid) {
        return;
      } 

      // add the is-invalid class to the enclosing form-group div
      element.classList.add('is-invalid');
  
      const formGroup = element.closest('.form-group');      
      if (!formGroup) {
        return;
      }

      // add help-block
      const message = document.createElement('div');
      message.className = 'invalid-feedback';
      message.textContent = result.message;
      message.id = `validation-message-${result.id}`;
      formGroup.appendChild(message);
    }
  
    remove(element: Element, result: ValidateResult) {
      if (result.valid) {
        return;
      }
  
      const formGroup = element.closest('.form-group');
      if (!formGroup) {
        return;
      }
  
      // remove help-block
      const message = formGroup.querySelector(`#validation-message-${result.id}`);
      if (message) {
        formGroup.removeChild(message);
  
        // remove the is-invalid class from the enclosing form-group div
        if (formGroup.querySelectorAll('.invalid-feedback').length === 0) {
          element.classList.remove('is-invalid');
        }
      }
    }
}

export class BootstrapValidationControllerFactory extends ValidationControllerFactory {
  constructor(container: Container) {
    super(container);      
  }
  public static get(container: Container) {
      return new BootstrapValidationControllerFactory(container);
  }
  
  createForCurrentScope(): ValidationController {
      let ctrl = super.createForCurrentScope();
      ctrl.addRenderer(new BootstrapFormRenderer());        
      return ctrl;
  }
}

export class BootstrapValidationController extends ValidationController {
  public static get(container: Container) {              
      return new BootstrapValidationControllerFactory(container).createForCurrentScope();
  }
}
(BootstrapValidationController as any)['protocol:aurelia:resolver'] = true;
