Momentum Preflight

Momentum Preflight is a Laravel package that lets you implement realtime backend-driven request validation for Inertia apps.

Validate form requests using Inertia form helper just like you already do, without running controllers' code.

Installation

Laravel

Install the package into your Laravel app.

composer require based/momentum-preflight

Register the PreflightMiddleware middleware.

<?php

Route::post('register', RegisterController::class)
  ->middleware(PreflightMiddleware::class);

Vue 3

The frontend package is only for Vue 3 now due to its wide adoption within the Laravel community.

Install the frontend package.

npm i momentum-preflight
# or
yarn add momentum-preflight

Usage

Preflight works well with both FormRequests and Laravel Data. Due to the simplicity of the approach, it doesn't support the inline $request->validate(...) method.

<?php

class RegisterController
{
    public function __invoke(RegisterRequest $request)
    {
        ...
    }
}

import { useForm } from "inertia/inertia-vue3";
import { useValidate } from "momentum-preflight";

const form = useForm({ name: "" });

const validate = useValidate(form, "/register", { debounce: 500 });

watch(
  () => form.data(),
  () => validate()
);

The package performs validation for all defined rules. However, you can specify exact fields so that all errors don't appear together once you start typing.

<script setup>
import { useForm } from "inertia/inertia-vue3";
import { useValidate } from "momentum-preflight";

const form = useForm({ name: "" });

const validate = useValidate(form, "/register");
</script>

<template>
  <div>
    <input v-model="form.name" @blur="validate('name')" />

    <span v-if="form.errors.name">{{ form.errors.name }}</span>
  </div>
</template>
