This guide covers:

Basic Atoms
Dependent Atoms
Async Atoms with loadable
Scoped Providers
Accessing Jotai Atoms Outside Components

Prerequisites

You’ll need:

TypeScript set up in your React project.
Install Jotai with npm install jotai jotai/utils.

Setting Up

Organize the project with a scalable folder structure.

src/
│
├── atoms/
│   ├── counterAtom.ts        # Basic counter atom
│   ├── dependentAtom.ts      # Dependent atom example
│   ├── dropdownAtoms.ts      # Async atoms with loadable
│   ├── scopedCounterAtom.ts  # Scoped counter atom
│
├── components/
│   ├── Counter.tsx           # Component for basic atom
│   ├── DependentCounter.tsx  # Component for dependent atom
│   ├── AsyncDropdown.tsx     # Component for async dropdowns
│   ├── ScopedCounter.tsx     # Component for scoped counters
│
└── App.tsx                   # Main app file

Basic Atom (Primitive Atom)

Step 1: Define the Atom in TypeScript

// src/atoms/counterAtom.ts
import { atom } from 'jotai';

export const counterAtom = atom<number>(0);

Step 2: Create the Counter Component

// src/components/Counter.tsx
import React from 'react';
import { useAtom } from 'jotai';
import { counterAtom } from '../atoms/counterAtom';

const Counter: React.FC = () => {
  const [count, setCount] = useAtom(counterAtom);

  return (
    <div>
      <h2>Count: {count}</h2>
      <button onClick={() => setCount((prev) => prev + 1)}>Increment</button>
    </div>
  );
};

export default Counter;

Step 3: Use the Counter Component in App.tsx

// src/App.tsx
import React from 'react';
import Counter from './components/Counter';

const App: React.FC = () => {
  return (
    <div>
      <h1>Jotai Basics</h1>
      <Counter />
    </div>
  );
};

export default App;

Creating Dependent Atoms

Step 1: Define Dependent Atom (dependentAtom.ts)

// src/atoms/dependentAtom.ts
import { atom } from 'jotai';
import { counterAtom } from './counterAtom';

export const doubleCounterAtom = atom((get) => get(counterAtom) * 2);

Step 2: Create Dependent Counter Component

// src/components/DependentCounter.tsx
import React from 'react';
import { useAtom } from 'jotai';
import { doubleCounterAtom } from '../atoms/dependentAtom';

const DependentCounter: React.FC = () => {
  const [doubleCount] = useAtom(doubleCounterAtom);

  return (
    <div>
      <h2>Double Count: {doubleCount}</h2>
    </div>
  );
};

export default DependentCounter;

Step 3: Add to App.tsx

// src/App.tsx
import React from 'react';
import Counter from './components/Counter';
import DependentCounter from './components/DependentCounter';

const App: React.FC = () => {
  return (
    <div>
      <h1>Jotai Basics</h1>
      <Counter />
      <DependentCounter />
    </div>
  );
};

export default App;

Async Atom with `loadable` for Cascaded Dropdowns

Using loadable, we can manage async atoms without needing Suspense, which is ideal for showing loading states directly within the component.

Step 1: Define Async Atoms with `loadable` (dropdownAtoms.ts)

// src/atoms/dropdownAtoms.ts
import { atom } from 'jotai';
import { loadable } from 'jotai/utils';

export const countryAtom = atom<string | null>(null);

export const stateAtom = loadable(
  atom(async (get) => {
    const selectedCountry = get(countryAtom);
    if (!selectedCountry) return [];

    const response = await fetch(`/api/states?country=${selectedCountry}`);
    return response.json();
  })
);

export const cityAtom = loadable(
  atom(async (get) => {
    const selectedState = get(stateAtom)?.data;
    if (!selectedState) return [];

    const response = await fetch(`/api/cities?state=${selectedState}`);
    return response.json();
  })
);

Step 2: Create the Async Dropdown Component

// src/components/AsyncDropdown.tsx
import React from 'react';
import { useAtom } from 'jotai';
import { countryAtom, stateAtom, cityAtom } from '../atoms/dropdownAtoms';

const AsyncDropdown: React.FC = () => {
  const [country, setCountry] = useAtom(countryAtom);
  const [states] = useAtom(stateAtom);
  const [cities] = useAtom(cityAtom);

  return (
    <div>
      <h2>Cascaded Dropdowns</h2>
      <label>
        Country:
        <select onChange={(e) => setCountry(e.target.value)}>
          <option value="">Select Country</option>
          <option value="usa">USA</option>
          <option value="canada">Canada</option>
        </select>
      </label>

      <label>
        State:
        {states.state === 'loading' ? (
          <p>Loading states...</p>
        ) : (
          <select>
            <option value="">Select State</option>
            {states.data.map((state) => (
              <option key={state.id} value={state.name}>
                {state.name}
              </option>
            ))}
          </select>
        )}
      </label>

      <label>
        City:
        {cities.state === 'loading' ? (
          <p>Loading cities...</p>
        ) : (
          <select>
            <option value="">Select City</option>
            {cities.data.map((city) => (
              <option key={city.id} value={city.name}>
                {city.name}
              </option>
            ))}
          </select>
        )}
      </label>
    </div>
  );
};

export default AsyncDropdown;

Step 3: Add Async Dropdown to App.tsx

// src/App.tsx
import React from 'react';
import AsyncDropdown from './components/AsyncDropdown';

const App: React.FC = () => {
  return (
    <div>
      <h1>Async with Jotai</h1>
      <AsyncDropdown />
    </div>
  );
};

export default App;

Using Scoped Providers

Scoped providers are helpful for creating isolated instances of atoms.

Step 1: Define Scoped Atom (scopedCounterAtom.ts)

// src/atoms/scopedCounterAtom.ts
import { atom } from 'jotai';

export const scopedCounterAtom = atom<number>(0);

Step 2: Scoped Component (ScopedCounter.tsx)

// src/components/ScopedCounter.tsx
import React from 'react';
import { useAtom } from 'jotai';
import { scopedCounterAtom } from '../atoms/scopedCounterAtom';

const ScopedCounter: React.FC = () => {
  const [count, setCount] = useAtom(scopedCounterAtom);

  return (
    <div>
      <h2>Scoped Count: {count}</h2>
      <button onClick={() => setCount((prev) => prev + 1)}>Increment</button>
    </div>
  );
};

export default ScopedCounter;

Step 3: App with Scoped Providers

// src/App.tsx
import React from 'react';
import { Provider } from 'jotai';
import ScopedCounter from './components/ScopedCounter';

const CounterScope1 = Symbol('CounterScope1');
const CounterScope2 = Symbol('CounterScope2');

const App: React.FC = () => {
  return (
    <div>
      <h1>Scoped Providers with Jotai</h1>
      <Provider scope={CounterScope1}>
        <ScopedCounter />
      </Provider>

      <Provider scope={CounterScope2}>
        <ScopedCounter />
      </Provider>
    </div>
  );
};

export default App;

Accessing Jotai Atoms Outside Components (Final Section)

Sometimes, you might need to interact with atoms outside of React components—perhaps in utility functions or side effects. Using the getDefaultStore method, you can directly get or set values in Jotai atoms.

Example: Using `get` and `set` Outside a Component

Set up a Jotai store:

// src/utils/jotaiStore.ts
import { getDefaultStore } from 'jotai';

const jotaiStore = getDefaultStore();
export default jotaiStore;

Create a utility function that uses the store:

// src/utils/incrementCounter.ts
import jotaiStore from './jotaiStore';
import { counterAtom } from '../atoms/counterAtom';

export function incrementCounter() {
  const currentCount = jotaiStore.get(counterAtom);
  jotaiStore.set(counterAtom, currentCount + 1);
}

Using the function:

You can now call incrementCounter() from anywhere in your app to increment counterAtom without directly involving React components.

Conclusion

With Jotai and TypeScript, you can build a finely-tuned state management layer that’s both minimal and powerful. This guide has covered the essentials, from basic and dependent atoms to asynchronous handling with loadable and using atoms outside components. Now you’re equipped to harness Jotai’s flexibility for creating stateful, reactive apps in a way that’s both scalable and efficient.

Achieving Asynchronous Parameterized Tests in Playwright with API Data

pgangwani — Fri, 25 Oct 2024 20:17:55 +0000

Introduction

In modern web development, automated testing is crucial for ensuring the reliability and performance of applications. Playwright, a powerful end-to-end testing framework, offers robust features for writing and running tests. One advanced technique is parameterized testing, where the same test is executed with different sets of data. This blog post will guide you through setting up asynchronous parameterized tests in Playwright using data fetched from an API.

Prerequisites

Before we dive in, make sure you have the following installed:

Node.js
Playwright
Axios (for making HTTP requests)

You can install Playwright and Axios using npm:

npm install @playwright/test axios

Step-by-Step Guide

1. Setting Up Your Project

Create a new directory for your project and initialize it:

mkdir playwright-api-tests
cd playwright-api-tests
npm init -y

2. Installing Dependencies

Install Playwright and Axios:

npm install @playwright/test axios

3. Writing the Test File

Create a test file, for example, api-tests.spec.ts, and set up your test cases to be fetched from an API.

import { test, expect } from '@playwright/test';
import axios from 'axios';

test.describe('API Parameterized Tests', () => {
  let testCases: { name: string, expected: string }[] = [];

  test.beforeAll(async () => {
    const response = await axios.get('https://api.example.com/test-cases');
    testCases = response.data;
  });

  testCases.forEach(({ name, expected }) => {
    test(`testing with ${name}`, async ({ page }) => {
      await page.goto(`https://example.com/greet?name=${name}`);
      await expect(page.getByRole('heading')).toHaveText(expected);
    });
  });
});

4. Running the Tests

Execute the tests using the Playwright test runner:

npx playwright test

Explanation

Fetching Data: The test.beforeAll hook is used to fetch test cases from the API before any tests run. This ensures that all test cases are available when the tests start.
Parameterized Tests: The testCases.forEach loop dynamically creates a test for each set of parameters retrieved from the API. This allows you to run the same test logic with different data sets.

Conclusion

By integrating API calls to fetch test data, you can create flexible and dynamic test suites in Playwright. This approach not only saves time but also ensures that your tests are always up-to-date with the latest data. Happy testing!
