gobrave

Bioinformatics Reactive Analysis & Visualization Engine — built in Go

🧬 What is gobrave?

gobrave is a high-performance bioinformatics platform that bridges the gap between pipeline engineering and scientific discovery. Built from the ground up in Go, it delivers unparalleled speed, a single-binary deployment, and a modern architecture designed for scale.

🚀 One binary. Zero friction. From raw data to publication-ready insights.

✨ Why gobrave?

🎯 Core Capabilities

⚙️ Visual DAG Workflow Engine

Design complex bioinformatics pipelines as directed acyclic graphs — no code required.

• 🎨 Drag-and-drop node composition (R, Python, Shell)
• 🔄 Automatic upstream → downstream data propagation
• 💾 Smart caching: skip unchanged nodes, re-run only what's needed
• 🧩 Scatter/gather patterns for parallel sample processing
• ♻️ Crash recovery with heartbeat-based lease locking

🐳 Containerized Analysis Workspaces

Launch full analysis environments on demand, right from your pipeline.

• RStudio Server · JupyterLab · VS Code Server — one-click launch
• Docker & Kubernetes runtime support
• Auto-provisioned reverse proxy (Traefik / K8s Ingress / built-in gateway)
• User-namespaced, isolated containers with host UID mapping

🌐 Real-time Collaboration

Stay in sync with every event in the system.

• WebSocket + SSE dual-transport realtime hub
• Per-user connection pooling with automatic eviction
• Live DAG execution progress, node status, and container events
• Frontend actions bridged via unified event bus

📁 Data Management

Organize your research artifacts with project-scoped CRUD.

• Datasets, Samples, Files — hierarchical, cross-referenced
• Role-based file annotation (e.g. FASTQ_R1, FASTQ_R2)
• Bulk import & project-level listing
• Transactional integrity with cascading cleanup

🚀 Quick Start

Prerequisites

• Go ≥ 1.25
• MySQL 8.0+
• Docker / Kubernetes / k3s (for containerized execution)

Install & Run

# Clone
git clone https://github.com/biox-dev/gobrave.git
cd gobrave

# Configure
cp config.example.yml config.yml
# Edit config.yml with your database & settings

# Run (it's that simple)
go run .

Install via go install

# Install the latest version into $GOPATH/bin (or $GOBIN)
go install github.com/biox-dev/gobrave@latest

# Configure
cp config.example.yml config.yml
# Edit config.yml with your database & settings

# Run
gobrave

Note: go install builds a plain binary without the embedded frontend. For a single executable with the frontend bundled, see Build a Single Executable with Embedded Frontend.

Build a Static Binary

# Build for your platform
go build -o gobrave .
# Run the binary
./gobrave

Build a Single Executable with Embedded Frontend

# 1) Build frontend artifacts into gobrave/frontend/web first (for example: copy brave-ui dist)
# 2) Build server with embedded frontend assets
go build -tags embed_frontend -o gobrave .

# Run as a single executable (no external web directory required at runtime)
./gobrave

Run with Docker

# Build Docker image
docker build -t gobrave:latest .
# Run container
docker run -d -p 8082:8082 --name gobrave gobrave:latest

docker run --rm -p 8082:8082  -it registry.cn-hangzhou.aliyuncs.com/wybioinfo/gobrave 

Run with Command-Line Database Configuration

You can override database settings directly via CLI flags — no config file needed. Timezone is fixed to UTC in all database DSNs.

# 1) Start MySQL via Docker
docker run -d --rm -p 53306:3306 \
   --name mysql \
   -e MYSQL_ROOT_PASSWORD=123456 \
   -e LANG=C.UTF-8 \
   --shm-size=10G \
   -v /home/admin/data/mysql:/var/lib/mysql \
   registry.cn-hangzhou.aliyuncs.com/wybioinfo/mysql:8.0.21 \
   --default-authentication-plugin=mysql_native_password \
   --character-set-server=utf8mb4 \
   --lower-case-table-names=1 \
   --collation-server=utf8mb4_unicode_ci
# 2) Create database
docker exec -it mysql mysql -uroot -p123456 -e "CREATE DATABASE brave CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;"

# 3) Download the latest release (single binary with embedded frontend)
wget https://github.com/biox-dev/gobrave/releases/download/v0.1.0/gobrave-v0.1.0-linux-amd64-embed -O gobrave
chmod +x gobrave

# 4) Run gobrave with CLI-specified database (no config.yml needed)
export GOBRAVE_BASE_DIR=/home/admin/.brave
./gobrave \
   --db-driver=mysql \
   --db-host=localhost \
   --db-port=53306 \
   --db-user=root \
   --db-password=123456 \
   --db-name=brave \
   --runtime=docker

Note: The database timezone is hardcoded to UTC in the connection string (loc=UTC for MySQL, TimeZone=UTC for PostgreSQL). Make sure your application logic accounts for UTC timestamps.

Available CLI flags for database:

Runtime Environment

K3s

# Install k3s (lightweight Kubernetes)
curl -sfL https://get.k3s.io | sh -
sudo cp /etc/rancher/k3s/k3s.yaml ~/.kube/config
# Check k3s status
kubectl get nodes

# Check kubectl version
kubectl version --client
