Step-by-Step Installation & Setup Guide

Download

Download the latest release for your platform from Releases.

• macOS: .dmg (Intel & Apple Silicon)
• Windows: .exe installer
• Linux: .AppImage, .deb, or .tar.gz (Arch)

macOS: Code Signing

Starting from v0.4.0, data-peek is code signed and notarized for macOS. You should be able to open it directly without any warnings.

If you're using an older version and see an "App is damaged" warning:

Option 1: Terminal command

xattr -cr /Applications/data-peek.app

Option 2: Right-click to open

1. Right-click (or Control+click) on data-peek.app
2. Select "Open" from the menu
3. Click "Open" in the dialog

Linux: Auto-Updates

Auto-updates only work with the AppImage format. If you installed via .deb or .tar.gz, you'll need to manually download new releases from the Releases page.

For the best experience with automatic updates, we recommend using the AppImage.

Build from Source

# Clone the repository
git clone https://github.com/Rohithgilla12/data-peek.git
cd data-peek

# Install dependencies
pnpm install

# Run in development mode
pnpm dev

# Build for your platform
pnpm build:mac    # macOS
pnpm build:win    # Windows
pnpm build:linux  # Linux

Troubleshooting: Electron not found

If you get errors about Electron not being found after pnpm install:

# Option 1: Run the setup script
pnpm setup:electron

# Option 2: Rebuild native modules
pnpm rebuild

# Option 3: Clean install (nuclear option)
pnpm clean:install

This can happen when pnpm's cache skips Electron's postinstall script that downloads platform-specific binaries.

REAL Code Examples from the Repository

Example 1: Querying Data with the AI Assistant

# Connect to your database using the AI assistant
# data-peek will generate the SQL query based on your natural language input

# Example natural language query
"Show me the top 5 customers by total sales"

# Generated SQL query
SELECT customer_id, SUM(amount) as total_sales
FROM sales
GROUP BY customer_id
ORDER BY total_sales DESC
LIMIT 5

This example demonstrates how the AI assistant can convert a natural language query into a SQL query. The AI understands the context and structure of your database to generate accurate queries.

Example 2: Creating a Table with the Table Designer

# Create a new table using the table designer
# data-peek provides a visual interface to define the table structure

CREATE TABLE customers (
  customer_id SERIAL PRIMARY KEY,
  name VARCHAR(100) NOT NULL,
  email VARCHAR(100) UNIQUE NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

The table designer allows you to create tables with full DDL support. You can define columns, indexes, constraints, and partitions all within the data-peek interface.

Example 3: Performance Analysis with Query Telemetry

# Analyze query performance using the query telemetry feature
# data-peek provides detailed timing breakdowns and waterfall visualizations

EXPLAIN ANALYZE
SELECT customer_id, SUM(amount) as total_sales
FROM sales
GROUP BY customer_id
ORDER BY total_sales DESC
LIMIT 5;

The query telemetry feature provides detailed insights into query performance. You can see a waterfall visualization of query execution times and get suggestions for optimizations.

Example 4: Inline Editing of Table Data

# Inline edit table data directly in data-peek
# data-peek supports INSERT, UPDATE, and DELETE operations

# Example: Update a customer's email
UPDATE customers
SET email = 'new_email@example.com'
WHERE customer_id = 1;

Inline editing allows you to directly modify table data. You can perform INSERT, UPDATE, and DELETE operations within the data-peek interface, making data management more efficient.

Example 5: Exporting Query Results

# Export query results to CSV, JSON, or Excel
# data-peek provides a simple interface to export your data

# Example: Export query results to CSV
SELECT customer_id, name, email
FROM customers
ORDER BY customer_id;

# Export to CSV
# data-peek will prompt you to choose the export format and file location

Data-peek allows you to export query results to various formats, making it easy to share and analyze your data outside of the application.
