# The App has moved to [mqtt-explorer.com](https://mqtt-explorer.com)
MQTT Explorer is a comprehensive and easy-to-use MQTT Client.
Downloads can be found at the link above.
This page is dedicated to its development.
Pull-Requests and error reports are welcome.
## Quick Start with GitHub Codespaces
The fastest way to start developing is with GitHub Codespaces:
1. Click the green "Code" button above
2. Select "Codespaces" tab
3. Click "Create codespace on [branch]"
4. Wait for the environment to set up (includes Node.js and MQTT broker)
5. Run `yarn dev:server` to start development
The devcontainer includes a pre-configured MQTT broker and all development tools. See [.devcontainer/README.md](.devcontainer/README.md) for details.
## Run from sources
### Desktop Application (Electron)
```bash
npm install -g yarn
yarn
yarn build
yarn start
```
### Browser Mode (Web Application)
MQTT Explorer can also run as a web application served by a Node.js server:
```bash
npm install -g yarn
yarn
yarn build:server
yarn start:server
```
Then open your browser to `http://localhost:3000`. For more details, see [BROWSER_MODE.md](BROWSER_MODE.md).
### Docker (Browser Mode)
[![Try in PWD](https://raw.githubusercontent.com/play-with-docker/stacks/master/assets/images/button.png)](https://labs.play-with-docker.com/?stack=https://raw.githubusercontent.com/thomasnordquist/MQTT-Explorer/master/docker-compose.yml)
Run MQTT Explorer in a Docker container:
```bash
docker run -d \
-p 3000:3000 \
-e MQTT_EXPLORER_USERNAME=admin \
-e MQTT_EXPLORER_PASSWORD=your_secure_password \
-v mqtt-explorer-data:/app/data \
ghcr.io/thomasnordquist/mqtt-explorer:latest
```
**Supports multiple platforms**: amd64, arm64 (Raspberry Pi 3/4/5), arm/v7 (Raspberry Pi 2/3).
**Enterprise integration**: Set `MQTT_EXPLORER_SKIP_AUTH=true` to disable built-in authentication when deploying behind a secure authentication proxy (e.g., OAuth2 Proxy, SSO).
For complete Docker documentation including authentication options, deployment examples, and security best practices, see [DOCKER.md](DOCKER.md).
## Develop
### Desktop Application
Launch Application
```bash
npm install -g yarn
yarn
yarn dev
```
### Browser Mode
Launch in development mode with hot reload:
```bash
npm install -g yarn
yarn
yarn dev:server
```
The `app` directory contains all the rendering logic, the `backend` directory currently contains the models, tests, connection management, `src` contains all the electron bindings. [mqttjs](https://github.com/mqttjs/MQTT.js) is used to facilitate communication to MQTT brokers.
## Automated Tests
MQTT Explorer uses multiple test suites to ensure reliability and quality:
### Unit Tests
**App tests** - Frontend component and logic tests:
```bash
yarn test:app
```
**Backend tests** - Data model and business logic tests:
```bash
yarn test:backend
```
**Run all unit tests**:
```bash
yarn test
```
### Integration & UI Tests
**UI test suite** - Independent, deterministic browser tests:
```bash
yarn build
yarn test:ui
```
**Demo video generation** - UI test recording for documentation:
```bash
yarn build
yarn test:demo-video
```
Note: Requires Xvfb, mosquitto broker, tmux, and ffmpeg. For full video recording setup, use `./scripts/uiTests.sh`.
**MCP introspection tests** - Model Context Protocol validation:
```bash
yarn build
yarn test:mcp
```
**Run all tests** (unit tests + demo video):
```bash
yarn build
yarn test:all
```
### Run UI Test Suite
The UI test suite validates core functionality through automated browser tests. Each test is independent and deterministic.
```bash
# Run with automated setup (recommended)
./scripts/runUiTests.sh
# Or run directly (requires manual MQTT broker setup)
yarn build
yarn test:ui
```
See [docs/UI-TEST-SUITE.md](docs/UI-TEST-SUITE.md) for more details.
### Run Demo Video Generation
The demo video is used for documentation and showcases key features. It requires additional dependencies:
```bash
yarn build
yarn test:demo-video
```
**Requirements:**
- mosquitto MQTT broker
- Xvfb (virtual framebuffer)
- tmux (terminal multiplexer)
- ffmpeg (video encoding)
**For full video recording with post-processing:**
```bash
yarn build
./scripts/uiTests.sh
```
This script handles Xvfb setup, mosquitto startup, video recording, and cleanup.
## Create a release
Create a PR to `release` branch.
There needs to be a "feat: some new feature" or "fix: some bugfix" commit for a new release to be created
### macOS Notarization
macOS builds are automatically notarized during the release process. To set up notarization credentials, see [NOTARIZATION.md](NOTARIZATION.md).
## Create a beta release
Create a PR to `beta` branch. A "feat" or "fix" commit is necessary to create a new version.
## Write docs
```
git clone --single-branch -b gh-pages https://github.com/thomasnordquist/MQTT-Explorer.git mqtt-explorer-pages
cd mqtt-explorer-pages
bundle install
bundle exec jekyll serve --incremental
```
Readme file: `Readme.tpl.md`
Preview is available at
http://localhost:4000/Readme.tpl
## Update docs
```
npm install
./updateReadme.ts
```
The readme will be generated from the docs.
