Top TypeScript Testing Libraries

Storybook is an open-source tool for building UI components and pages in isolation, making it easier to develop, test, and document React, Vue, Angular, and other web applications.

Code Example

import { Button } from './Button';

export default {
  component: Button,
  title: 'Components/Button',
};

export const Primary = () => <Button primary>Click me</Button>;

Pros

• Storybook offers a comprehensive UI development environment with support for multiple frameworks, unlike more specialized tools like Ladle or framework-specific boilerplates.
• It provides extensive documentation and a large ecosystem of addons, making it more versatile than many other projects in the list.
• Storybook's isolated component development approach can lead to better code organization and reusability compared to full-stack boilerplates or testing-focused tools.

Cons

• Storybook has a steeper learning curve compared to simpler alternatives like Ladle or framework-specific boilerplates.
• It can add complexity to a project's setup, which might be unnecessary for smaller applications or teams preferring integrated solutions like Next.js boilerplates.
• Storybook focuses primarily on UI components and may not provide the full-stack testing capabilities offered by tools like TestCafe or Artillery.

Bun is an all-in-one JavaScript runtime, bundler, and package manager designed for speed and efficiency.

Code Example

import { serve } from "bun";

serve({
  fetch(req) { return new Response("Hello World!"); }
});

Pros

• Significantly faster execution and bundling compared to Node.js and other JavaScript runtimes.
• Built-in package manager that outperforms npm and yarn in speed and efficiency.
• Comprehensive toolkit combining runtime, bundler, and package manager in one solution.

Cons

• Less mature ecosystem compared to established projects like Node.js or webpack.
• Limited compatibility with some existing Node.js packages and APIs.
• Smaller community and fewer resources compared to more established JavaScript tools.

PostHog is an open-source product analytics platform that helps teams understand user behavior and improve their products.

Pros

• Offers a comprehensive suite of product analytics tools, including feature flags and session recording, which many other projects don't provide.
• Self-hosted option available, giving more control over data and privacy compared to SaaS-only solutions.
• Integrates well with various data sources and platforms, making it versatile for different tech stacks.

Cons

• More complex to set up and maintain compared to some lighter-weight analytics solutions.
• May have a steeper learning curve for teams new to product analytics.
• Resource-intensive for smaller projects or teams compared to simpler alternatives.

AdonisJS is a full-featured MVC framework for Node.js, focusing on developer productivity and elegant syntax.

Code Example

import { HttpContextContract } from '@ioc:Adonis/Core/HttpContext'

export default class UsersController {
  public async index({ response }: HttpContextContract) {
    return response.json({ message: 'Hello from AdonisJS' })
  }
}

Pros

• Provides a complete ecosystem with built-in authentication, database ORM, and testing tools, unlike some other projects that focus on specific aspects.
• Offers a more opinionated structure compared to flexible boilerplates like Next.js Boilerplate or SaaS Boilerplate, potentially speeding up development.
• Has a strong focus on TypeScript support, similar to ts-jest but applied across the entire framework.

Cons

• May have a steeper learning curve compared to more lightweight alternatives like Bun or Express-based setups.
• Less flexible for customization than generic boilerplates or lower-level tools like Hardhat for blockchain development.
• Smaller community and ecosystem compared to more widely adopted frameworks like Next.js or testing tools like Jest.

ixartz/Next-js-Boilerplate is a starter template for Next.js projects with TypeScript, ESLint, Prettier, and other best practices pre-configured.

Code Example

import { NextPage } from 'next';
import { Main } from '@/templates/Main';

const Index: NextPage = () => {
  return <Main meta={<Meta title="Home" description="Welcome to Next.js Boilerplate" />}>
    <h1>Welcome to Next.js Boilerplate</h1>
  </Main>;
};

Pros

• Provides a comprehensive, production-ready setup for Next.js projects, saving development time.
• Includes modern tooling and best practices out of the box, ensuring code quality and consistency.
• Regularly updated and maintained, keeping up with the latest Next.js features and ecosystem changes.

Cons

• More opinionated and less flexible compared to some other boilerplates or frameworks like AdonisJS or Vuesion.
• Lacks some advanced features found in enterprise-level boilerplates like Blazity/next-enterprise.
• May have a steeper learning curve for beginners compared to simpler setups or vanilla Next.js projects.
