Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Elevate your form development with Ninja Form Kit, a powerful TypeScript library that seamlessly integrates with your theme. This robust toolkit unifies UI generation and form validation into a single configuration object, streamlining your workflow.

Installation

To install Ninja Form Kit, use npm or yarn:

npm install ninjaformkit
# or
yarn add ninjaformkit

Quick Start

To configure your form, define a formConfig object in your +page.server.ts file. This object allows you to specify form properties such as method, action, fields, and validation rules. For optimal type safety, ensure your formConfig adheres to the FormConfig interface. Important: Define formConfig outside the load function to guarantee accessibility within actions.

Define the config in loader


import { type FormConfig } from 'ninjaformkit'

const formConfig = {
	method: 'post',
	fields: {
		email: {
			type: 'text',
			variant: 'email',
			placeholder: 'Enter your email...',
			label: 'Email',
			validate: {
				required: true,
				isEmail: true
			}
		},
		message: {
			type: 'textarea',
			placeholder: 'Enter your message...',
			label: 'Message',
			validate: {
				required: true,
				minLength: 10,
				maxLength: 500
			}
		},
		submit: {
			type: 'submit',
			label: 'Submit'
		}
	}
} satisfies FormConfig;

export const load: PageServerLoad = async () => {
	return { formConfig };
};

Use the Form in your template/component


<script lang="ts">
    import { Form } from 'ninjaformkit'
    export let data;
</script>

<Form config={data.formConfig} />

Validate the form with actions


import { validate } from 'ninjaformkit'

export const actions = {
	default: async ({ request }) => {
		const { errors, hasErrors, values } = await validate(request, formConfig);

		if (hasErrors) {
                        // Errors will appears under each input that validation fails
			return fail(400, { errors });
		}

	// Process the type safe form values 
        await sendEmail({
            email: values.email, // string
            message: values.message // string
        });
        
        return redirect(301, '/');
 
	}
} satisfies Actions;
