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 🙏

Demo

Prerequisites

  • node >=18
  • nextjs >= 9

Install

yarn add next-validations

Features

  • Support for Multiple Validation Libraries: This package is designed to work seamlessly with a variety of popular validation libraries. These include Yup, Fastest-Validator, Joi, Zod, and Valibot. This means you can choose the library that best suits your project's needs.

  • Integration with TypeSchema: next-validations integrates with TypeSchema - Universal adapter for TypeScript schema validation. This allows for even more flexibility and compatibility with additional validation libraries.

Usage

Validation of multiple modes

yarn add yup joi next-validations @typeschema/yup @typeschema/yoi
import Joi from 'joi';
import { NextApiRequest, NextApiResponse } from 'next';
import { createRouter } from 'next-connect';
import { withValidations } from 'next-validations';
import * as yup from 'yup';

const querySchema = yup.object().shape({
  type: yup.string().oneOf(['email', 'sms']).required(),
});

const validateQuery = {
  schema: querySchema,
  type: 'Yup',
  mode: 'query',
} as const;

const bodySchema = Joi.object({
  phone: Joi.string().required(),
  email: Joi.string().email().required(),
  name: Joi.string().required(),
});

const validateBody = {
  schema: bodySchema,
  type: 'Joi',
  mode: 'body',
} as const;

const validate = withValidations([validateQuery, validateBody]);

const handler = (req: NextApiRequest, res: NextApiResponse) => {
  res.status(200).json({ ...req.body, ...req.query });
};

export default connect().post(validate(), handler);

Validate custom API endpoint with Yup

yarn add yup next-validations @typeschema/yup
import { NextApiRequest, NextApiResponse } from 'next';
import { withValidation } from 'next-validations';
import * as yup from 'yup';

const schema = yup.object().shape({
  name: yup.string().required(),
});

const validate = withValidation({
  schema,
  type: 'Yup',
  mode: 'query',
});

const handler = (req: NextApiRequest, res: NextApiResponse) => {
  res.status(200).json(req.query);
};

const router = createRouter();

router.post(validate(), handler);

export default router.handler({
  onError: (err, _req, _event) => {
    return new NextResponse('Something broke!', {
      status: (err as any)?.statusCode ?? 500,
    });
  },
});

Validate custom API endpoint with Zod

yarn add zod next-validations @typeschema/zod
import { NextApiRequest, NextApiResponse } from 'next';
import { withValidation } from 'next-validations';
import { z } from 'zod';

const schema = z.object({
  username: z.string().min(6),
});

const validate = withValidation({
  schema,
  type: 'Zod',
  mode: 'body',
});

const handler = (req: NextApiRequest, res: NextApiResponse) => {
  res.status(200).json(req.body);
};

export default validate(handler);

Validate custom API endpoint with Valibot

yarn add valibot next-validations @typeschema/valibot
import { NextApiRequest, NextApiResponse } from 'next';
import { withValidation } from 'next-validations';
import * as valibot from 'valibot';

const schema = valibot.object({
  name: valibot.string([valibot.minLength(4)]),
});

const validate = withValidation({
  schema,
  type: 'Valibot',
  mode: 'query',
});

const handler = (req: NextApiRequest, res: NextApiResponse) => {
  res.status(200).json(req.query);
};

export default validate(handler);

Validate custom API endpoint with fastest-validator

yarn add fastest-validator next-validations @typeschema/fastest-validator
import { NextApiRequest, NextApiResponse } from 'next';
import { withValidation } from 'next-validations';

const schema = {
  name: { type: 'string', min: 3, max: 255 },
  email: { type: 'email' },
  age: 'number',
};

const validate = withValidation({
  schema,
  type: 'FastestValidator',
  mode: 'body',
});

const handler = (req: NextApiRequest, res: NextApiResponse) => {
  res.status(200).json(req.body);
};

export default validate(handler);

Validate custom API endpoint with joi

yarn add joi next-connect next-validations @typeschema/joi
import Joi from 'joi';
import { NextApiRequest, NextApiResponse } from 'next';
import { createRouter } from 'next-connect';
import { withValidation } from 'next-validations';

const schema = Joi.object({
  dob: Joi.date().iso(),
  email: Joi.string().email().required(),
  name: Joi.string().required(),
});

const validate = withValidation({
  schema,
  type: 'Joi',
  mode: 'body',
});

const handler = (req: NextApiRequest, res: NextApiResponse) => {
  res.status(200).json(req.body);
};

const router = createRouter();

router.post(validate(), handler);

export default router.handler({
  onError: (err, _req, _event) => {
    return new NextResponse('Something broke!', {
      status: (err as any)?.statusCode ?? 500,
    });
  },
});
