Features

Multiple Environment Schemes: Create, edit, duplicate, and delete environment variable schemes
One-Click Switch: Quickly switch between different environment configurations
Persistent Storage: Schemes are saved locally and persist across sessions
Shell Integration: Automatically updates your shell environment (~/.switch_env)
Import/Export: Share your environment schemes with others
Custom Window: macOS-style frameless window with transparent background and rounded corners
Auto-Reload: Changes to the currently applied scheme are immediately reflected

Tech Stack

Backend: Go with Wails v2
Frontend: React 18 + TypeScript + Tailwind CSS
Runtime: Native desktop application

Getting Started

Prerequisites

Go 1.23+
Node.js & npm
Wails CLI

Installation

# Install Wails CLI if not already installed
go install github.com/wailsapp/wails/v2/cmd/wails@latest

# Clone and setup
git clone https://github.com/dean2021/SwitchEnvs.git
cd SwitchEnvs

# Install frontend dependencies
cd frontend && npm install

# Return to project root
cd ..

Development

Run the application in development mode with hot reload:

wails dev

This will start both the Go backend and the React frontend with automatic rebuilding.

Building

Build the production version:

wails build

Build for specific platforms:

# macOS ARM64
wails build -platform darwin/arm64

# Windows AMD64
wails build -platform windows/amd64

# Linux
wails build -platform linux/amd64

Usage

Creating a Scheme

Click "Add Scheme" to create a new environment scheme
Add key-value pairs for your environment variables
Click "Apply" to activate the scheme

Switching Schemes

Select a scheme from the sidebar
Click "Apply" to switch to that environment configuration

Exporting/Importing

Use the export button to save your schemes as JSON
Use the import button to load schemes from a JSON file

Data Storage

Path	Purpose
`~/.switchenvs/schemes.json`	All saved schemes in JSON format
`~/.switchenvs/applied_scheme.json`	Persisted applied scheme name
`~/.switch_env`	Shell script with `export KEY="value"` entries

Architecture

Backend (Go)

The Go backend handles:

Scheme CRUD operations (Save, Get, Delete, Duplicate)
Applying schemes to the system
Writing environment variables to shell config
Import/Export functionality

Frontend (React + TypeScript)

The frontend provides:

Interactive UI for managing environment schemes
Real-time updates when switching schemes
Import/Export dialogs
Custom window controls (minimize, close)

Shell Integration

SwitchEnvs writes environment variables to ~/.switch_env and automatically adds a source command to ~/.zshrc. To use the environment variables in your terminal:

source ~/.switch_env

Or restart your terminal session.
