How it works

KVM turns the Linux kernel itself into a type-1 hypervisor. Each virtual machine runs as a regular
Linux process, and hardware virtualization extensions (Intel VT-x or AMD-V) execute guest code
efficiently with full isolation from the host and other VMs.

Key insight: Because KVM is part of the kernel, it automatically benefits from all kernel
improvements — scheduling, memory management, and security patches — without any additional overhead.

Key features

Hardware acceleration — Leverages Intel VT-x and AMD-V extensions for efficient, low-overhead VM execution.
Security and isolation — Each VM is a separate Linux process with strict memory and resource isolation.
Near-native performance — Minimal virtualization overhead compared to software-emulated hypervisors.
Scalability — Scales from single-node dev setups to large enterprise cloud deployments.
Multi-OS support — Run Linux, Windows, BSD, and other guest operating systems side by side.
Cost-effective — Fully open-source with no licensing fees, backed by a large upstream community.

Use cases

Server virtualization — Consolidate workloads across fewer physical machines with strong isolation guarantees.
Private and hybrid cloud — Forms the virtualization layer in OpenStack, oVirt, and similar platforms.
Development and testing — Spin up reproducible environments for CI pipelines and local dev workflows.
Virtual data centers — Manage large pools of compute resources with live migration and high availability.
Cloud infrastructure — Used by major cloud providers as the underlying hypervisor layer.

Core components

Component	Role
KVM kernel module	Provides the hypervisor layer inside the Linux kernel
QEMU	Hardware emulation layer for device and I/O simulation
libvirt	API and daemon for VM lifecycle management
virt-manager	GUI and CLI tooling for provisioning and managing VMs

Benefits

KVM offers enterprise-grade reliability with the cost advantages of open source. Its deep integration
with the Linux kernel means security and performance improvements flow in automatically with every kernel update.

Near-native performance through hardware-assisted virtualization
No licensing costs — fully open-source under GPL
Seamless integration with Linux tooling, storage, and networking
Strong security model with SELinux and sVirt support
Active upstream development backed by Red Hat, IBM, and the broader community

Automate NPM Package Publishing with GitHub Actions

PEAKIQ — Sun, 10 May 2026 03:25:57 +0000

How to Publish an NPM Package Automatically with GitHub Actions

Publishing NPM packages can be a cornerstone of modern development, enabling code reuse and collaboration. However, manually publishing updates can be repetitive, error-prone, and time-consuming. This is where Continuous Integration/Continuous Deployment (CI/CD) shines, and GitHub Actions provides a powerful, integrated solution to automate this process.

At PeakIQ, we advocate for automation to streamline development workflows. This guide will walk you through setting up a GitHub Actions workflow to automatically build, test, and publish your NPM package, ensuring a smooth and secure release process.

Why Automate NPM Package Publishing?

Before diving into the "how," let's quickly recap the compelling reasons to automate your package publishing:

Consistency: Every release follows the same steps, reducing human error.
Speed: Releases can be deployed much faster without manual intervention.
Reliability: Automated tests ensure your package is working correctly before it's published.
Security: Sensitive credentials are handled securely via GitHub Secrets, not exposed in your local environment.
Developer Experience: Free up developers from mundane release tasks to focus on building features.

Prerequisites

To follow along with this guide, you'll need:

A GitHub account and a repository for your NPM package.
An NPM account.
Basic understanding of Git, GitHub, and NPM.
A Node.js project initialized as an NPM package (package.json).

Setting Up Your NPM Project

Ensure your NPM package is ready for publication. This typically involves:

package.json: Make sure it has a name, version, and main entry point.
Build Script (Optional but Recommended): If your package requires compilation (e.g., TypeScript, Babel), include a build script in your package.json's scripts section.
Test Script: A test script is crucial for CI/CD. GitHub Actions will run these tests before publishing.

Here's a minimal package.json example:

{
  "name": "@your-scope/your-package-name",
  "version": "1.0.0",
  "description": "A simple example NPM package.",
  "main": "dist/index.js",
  "scripts": {
    "build": "mkdir -p dist && echo 'console.log(\"Hello from your package!\");' > dist/index.js",
    "test": "echo \"No tests specified, but we passed!\" && exit 0",
    "prepublishOnly": "npm run build"
  },
  "keywords": ["example", "peakiq"],
  "author": "PeakIQ",
  "license": "MIT"
}

Note: For a real project, replace the build and test scripts with your actual build tools and testing frameworks.

Generating an NPM Access Token

For GitHub Actions to publish to NPM, it needs authorization. You'll generate a special token from NPM and store it securely in GitHub.

Log in to NPM: Visit https://www.npmjs.com/ and log in to your account.
Generate a Token: Go to your profile settings -> "Auth Tokens" and click "Generate New Token."
Select "Publish" Role: Choose the "Publish" token type. This grants the token only the necessary permissions to publish packages, minimizing risk.
Copy the Token: Once generated, copy the token immediately. You won't be able to see it again.

Adding the Token to GitHub Secrets

Now, add this token to your GitHub repository as a secret:

Navigate to your GitHub repository.
Go to Settings > Secrets and variables > Actions.
Click New repository secret.
For "Name," enter NPM_TOKEN.
For "Secret," paste the NPM token you copied.
Click Add secret.

This secret will now be securely available to your GitHub Actions workflows.

Creating Your GitHub Actions Workflow

GitHub Actions workflows are defined in YAML files located in the .github/workflows/ directory of your repository.

Create a new directory: .github/workflows/ in the root of your project.
Create a new file inside: publish-package.yml (or any descriptive name).

Here's the complete workflow file:

name: Publish NPM Package

on:
  release:
    types: [published]
  workflow_dispatch:

jobs:
  publish:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout repository
        uses: actions/checkout@v4

      - name: Set up Node.js
        uses: actions/setup-node@v4
        with:
          node-version: '18.x' # Or your preferred Node.js version
          registry-url: 'https://registry.npmjs.org/'

      - name: Install dependencies
        run: npm ci

      - name: Run tests
        run: npm test

      - name: Build package (if applicable)
        run: npm run build
        if: always() # Ensure this runs even if tests fail, or adjust as needed

      - name: Publish to NPM
        env:
          NODE_AUTH_TOKEN: ${{ secrets.NPM_TOKEN }}
        run: npm publish --access public

Let's break down this workflow:

`name`

name: Publish NPM Package

A human-readable name for your workflow, visible in the GitHub Actions tab.

`on`

on:
  release:
    types: [published]
  workflow_dispatch:

This defines when the workflow should run:

release: types: [published]: The workflow will trigger automatically whenever a new GitHub Release is published. This is a common and recommended approach for managing package versions and releases.
workflow_dispatch: Allows you to manually trigger the workflow from the "Actions" tab in your GitHub repository. Handy for testing or specific scenarios.

`jobs`

jobs:
  publish:
    runs-on: ubuntu-latest
    steps:
      # ... steps defined below

A workflow can have one or more jobs. Here, we have a single publish job that runs on an ubuntu-latest virtual machine.

`steps`

Each job consists of a series of steps executed sequentially.

Checkout repository:
```
- name: Checkout repository
  uses: actions/checkout@v4
```
This step uses the actions/checkout action to clone your repository's code onto the runner, making it available for subsequent steps.
Set up Node.js:
```
- name: Set up Node.js
  uses: actions/setup-node@v4
  with:
    node-version: '18.x'
    registry-url: 'https://registry.npmjs.org/'
```
The actions/setup-node action sets up the specified Node.js version and configures NPM to use the official registry. Crucially, the registry-url option, combined with NODE_AUTH_TOKEN in the publish step, tells NPM where to publish and how to authenticate.
Install dependencies:
```
- name: Install dependencies
  run: npm ci
```
npm ci (clean install) is preferred over npm install in CI environments because it strictly installs dependencies based on package-lock.json, ensuring consistent builds.
Run tests:

E2E Testing React Native with Maestro: A Practical Guide

PEAKIQ — Wed, 06 May 2026 04:35:57 +0000

Originally published on PEAKIQ

E2E Testing Your React Native App with Maestro

Writing end-to-end tests for mobile apps has always been painful. Appium needs drivers. Detox needs native build hooks. Everything breaks when your UI shifts by 4 pixels. Maestro changes that. It talks to your app the same way a user does — through the accessibility layer — and writes tests in plain YAML.

This guide covers everything: installation, writing your first flow, handling iOS quirks, and plugging Maestro into your CI pipeline.

Why Maestro?

Before we dive in, here's why Maestro stands out against the traditional tools.

Feature	Maestro	Detox	Appium
Setup complexity	Minimal	High	Very High
Language	YAML	JS/TS	JS/Python/Java
Platform support	iOS + Android	iOS + Android	iOS + Android
Zero app changes	✅	❌	❌
Flakiness handling	Built-in auto-wait	Manual sleeps	Manual sleeps
Expo support	✅ First-class	Limited	Limited

Info: Maestro operates entirely at the accessibility layer. It doesn't touch your JavaScript source, doesn't need npm packages inside your app, and tests the final compiled binary — just like a real user would use it.

Prerequisites

Node.js ≥ 18
React Native CLI or Expo project
For iOS: Xcode + Simulator running
For Android: Android Studio + AVD Manager with an emulator running

Installation

Step 1 — Install Maestro CLI

curl -Ls "https://get.maestro.mobile.dev" | bash

Maestro is compatible with macOS, Windows, and Linux. Verify the install:

maestro --version

Step 2 — Start your simulator/emulator

iOS (macOS only):

open -a Simulator

Android:

emulator -avd Pixel_6_API_33

Step 3 — Install and launch your app

# React Native CLI
npx react-native run-ios
npx react-native run-android

# Expo
npx expo start --ios
npx expo start --android

Your First Flow

Create a .maestro/ folder at the root of your project. This is where all your test flows live.

your-app/
├── .maestro/
│   ├── sign-in-flow.yaml
│   └── onboarding-flow.yaml
├── src/
└── package.json

Here's a minimal flow that launches your app and taps a button:

# .maestro/sign-in-flow.yaml
appId: com.yourapp.bundle
---
- launchApp
- tapOn: "Sign In"
- inputText:
    text: "hello@example.com"
    label: "Email"
- inputText:
    text: "supersecret"
    label: "Password"
- tapOn: "Continue"
- assertVisible: "Welcome back"

Run it:

maestro test .maestro/sign-in-flow.yaml

That's it. No compilation step, no linking, no driver setup.

Targeting Components

Maestro gives you two clean ways to target elements in your React Native app.

By visible text

If your component renders visible text, Maestro can find it directly:

- tapOn: "Add to Cart"
- assertVisible: "Item added"

By `testID`

For components without unique visible text (icons, image buttons), add a testID:

<TouchableOpacity testID="submit-button" onPress={handleSubmit}>
  <Icon name="arrow-right" />
</TouchableOpacity>

Then in your flow:

- tapOn:
    id: "submit-button"

Tip: Prefer testID over text matching for interactive elements. It decouples your tests from copy changes and internationalization.

Handling Text Input

Text input requires two steps: focus the field, then type.

Your React Native component:

<TextInput
  testID="email-input"
  placeholder="Enter your email"
  onChangeText={setEmail}
  keyboardType="email-address"
/>

Your Maestro flow:

- tapOn:
    id: "email-input"
- inputText: "hello@maestro.dev"
- hideKeyboard

Assertions

Maestro ships with a concise set of assertions out of the box.

# Assert an element is visible
- assertVisible: "Dashboard"

# Assert by testID
- assertVisible:
    id: "user-avatar"

# Assert something is NOT on screen
- assertNotVisible: "Loading..."

# Assert text content
- assertVisible:
    text: "You have 3 notifications"

Handling iOS Nested Accessibility (Common Gotcha)

On iOS, React Native sometimes "swallows" touch events when components are deeply nested. You'll hit this when trying to tap something inside a Pressable or TouchableOpacity that's inside another tappable container.

The fix — in your React Native component:

// ❌ Before — inner Text is unreachable
<TouchableOpacity onPress={handlePress}>
  <View>
    <Text>Tap me</Text>
  </View>
</TouchableOpacity>

// ✅ After — disable accessibility on outer, enable on inner
<TouchableOpacity accessible={false} onPress={handlePress}>
  <View>
    <Text accessible={true} testID="tap-target">Tap me</Text>
  </View>
</TouchableOpacity>

Your flow stays clean:

- tapOn:
    id: "tap-target"

Advanced: Parameterized Flows

Avoid duplicating flows for different test scenarios. Use Maestro's parameter support:

# .maestro/sign-in-flow.yaml
appId: com.yourapp.bundle
---
- launchApp
- tapOn: "Email"
- inputText: ${EMAIL}
- tapOn: "Password"
- inputText: ${PASSWORD}
- tapOn: "Sign In"
- assertVisible: "Dashboard"

Run with parameters:

maestro test .maestro/sign-in-flow.yaml \
  -e EMAIL=test@example.com \
  -e PASSWORD=mypassword

This is especially powerful for testing multiple user roles or locales without duplicating flow files.

Running a Full Test Suite

Run every flow in your .maestro/ directory with a single command:

maestro test .maestro/

Maestro will execute all .yaml files sequentially and report results for each one.

Integrating with CI/CD

GitHub Actions

# .github/workflows/e2e.yml
name: E2E Tests

on:
  push:
    branches: [main]
  pull_request:

jobs:
  e2e-android:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - name: Set up JDK
        uses: actions/setup-java@v4
        with:
          distribution: "temurin"
          java-version: "17"

      - name: Install Maestro
        run: curl -Ls "https://get.maestro.mobile.dev" | bash

      - name: Build APK
        run: cd android && ./gradlew assembleDebug

      - name: Start emulator
        uses: reactivecircus/android-emulator-runner@v2
        with:
          api-level: 33
          script: |
            adb install android/app/build/outputs/apk/debug/app-debug.apk
            maestro test .maestro/

Maestro Cloud (Optional)

For parallel execution across real devices, push to Maestro Cloud:

maestro cloud \
  --apiKey $MAESTRO_API_KEY \
  android/app/build/outputs/apk/debug/app-debug.apk \
  .maestro/

This gives you a visual dashboard of historical runs, device logs, and screenshots on failure.

Sample App: Complete Example

Here's a minimal React Native screen and its corresponding Maestro flow.

App.tsx:

import React, { useState } from "react";
import { SafeAreaView, Button, Text, TextInput, StyleSheet } from "react-native";

export default function App() {
  const [taps, setTaps] = useState(0);
  const [text, setText] = useState("");

  return (
    <SafeAreaView style={styles.container}>
      <Button title="Add one" onPress={() => setTaps(taps + 1)} />
      <Button
        title="Add ten"
        testID="add_ten"
        onPress={() => setTaps(taps + 10)}
      />
      <Text>Number of taps: {taps}</Text>
      <TextInput
        testID="text_input"
        placeholder="Change me!"
        onChangeText={setText}
        style={styles.input}
      />
      <Text>You typed: {text}</Text>
    </SafeAreaView>
  );
}

const styles = StyleSheet.create({
  container: { flex: 1, alignItems: "center", justifyContent: "center" },
  input: { borderWidth: 1, width: 200, padding: 8, marginTop: 12 },
});

.maestro/counter-flow.yaml:

appId: com.myapp
---
- launchApp
- tapOn: "Add one"
- tapOn:
    id: "add_ten"
- assertVisible: "Number of taps: 11"
- tapOn: "Change me!"
- inputText: "Hello, Maestro!"
- assertVisible: "You typed: Hello, Maestro!"

Tips for Reliable Tests

Always use testID for anything interactive. Text changes. testID doesn't (unless you change it deliberately).
Don't use sleep. Maestro automatically waits for elements to appear. Explicit sleeps are a code smell — if you think you need one, something else is wrong.
Keep flows small and composable. One flow = one user journey. A sign-in flow shouldn't also test the profile page.
Reset app state between runs. Use clearState: true in launchApp to ensure a clean slate:

- launchApp:
    clearState: true

Use runFlow for shared setup:

# .maestro/helpers/login.yaml
---
- tapOn: "Email"
- inputText: ${EMAIL}
- tapOn: "Sign In"

# Your main flow
---
- launchApp
- runFlow: helpers/login.yaml
- assertVisible: "Dashboard"

Conclusion

Maestro removes the friction from mobile E2E testing. No native bridges, no custom drivers, no flaky sleeps — just YAML that reads like a QA script and runs like a charm.

With full support for both Expo and React Native CLI, built-in handling of timing and async UI, and a one-line CI setup, there's very little reason not to add Maestro to your project today.

Get started:

curl -Ls "https://get.maestro.mobile.dev" | bash
maestro test .maestro/your-first-flow.yaml

Happy testing.

Complex state-driven user interfaces
Applications with shared global state
Real-time dashboards
Enterprise-level front-end systems

⚡ Benefits

Predictable and maintainable state logic
Easier debugging and testing
Clear separation of concerns
Improved scalability for large applications
Strong community and long-term support

📦 Tech Stack

Redux
JavaScript / TypeScript
Redux Toolkit
React (optional but commonly used)
Middleware (Thunk, Saga, etc.)

✅ Why Choose This Redux Tool?

This tool simplifies state management by enforcing best practices, reducing boilerplate, and providing powerful debugging capabilities—making it ideal for complex and growing applications.
