LibreChat uses the packageManager field in package.json to specify [email protected]. Modern Node.js installations will automatically use the correct version.

Docker Installation (Recommended)

Docker is the recommended installation method for most users. It provides isolation, easy updates, and consistent environments.

Standard Docker Setup

Install Docker

Install Docker Desktop or Docker Engine on your system:

# Update package index
sudo apt update

# Install Docker
sudo apt install docker.io docker-compose-plugin

# Start Docker service
sudo systemctl enable --now docker

# Add your user to docker group (logout/login required)
sudo usermod -aG docker $USER

Verify installation:

docker --version
docker compose version

Clone Repository

git clone https://github.com/danny-avila/LibreChat.git
cd LibreChat

Configure Environment

Create and configure your .env file:

cp .env.example .env

Edit .env with your preferred editor. Required configuration:

.env

# Server Configuration

Install Dependencies

LibreChat uses npm workspaces. Install all dependencies:

# Smart install (only if package-lock.json changed)
npm run smart-reinstall

# Or full clean install
npm run reinstall

This installs dependencies for:

Root workspace
/api - Backend server
/client - Frontend React app
/packages/* - Shared libraries

Build the Application

# Build all packages (uses Turborepo for speed)
npm run build

This compiles:

packages/data-provider - Shared API types
packages/data-schemas - Database schemas
packages/api - TypeScript backend code
packages/client - Frontend utilities
client - React frontend build

Start Meilisearch

In a separate terminal:

# Linux/macOS
meilisearch --master-key="your_secure_master_key" --db-path ./meili_data

# Or run as background service
meilisearch --master-key="your_secure_master_key" --db-path ./meili_data &

Start the Backend

In the main terminal:

# Production mode
npm run backend

# Development mode (with file watching)
npm run backend:dev

The backend runs on http://localhost:3080

Start the Frontend (Development)

For development with hot module reloading, in another terminal:

npm run frontend:dev

The dev server runs on http://localhost:3090 and proxies API requests to :3080

Access LibreChat

Production build: http://localhost:3080
Development: http://localhost:3090

Troubleshooting

Docker Issues

Container fails to start

# Check logs
docker compose logs api

# Common issues:
# 1. Port conflict - change PORT in .env
# 2. Invalid .env format - check for quotes/spaces
# 3. Permission errors - verify UID/GID settings

# Reset containers
docker compose down
docker compose up -d

MongoDB connection errors

# Check MongoDB is running
docker compose ps mongodb

# View MongoDB logs
docker compose logs mongodb

# Reset MongoDB (WARNING: deletes data)
docker compose down
sudo rm -rf ./data-node
docker compose up -d

File permission errors

# Fix ownership of data directories
sudo chown -R $(id -u):$(id -g) ./data-node ./meili_data_v1.35.1 ./uploads ./logs

# Ensure UID/GID are set in .env
echo "UID=$(id -u)" >> .env
echo "GID=$(id -g)" >> .env

docker compose restart

Local Installation Issues

Build errors

# Clear caches and rebuild
npm run reinstall
npm run build

# If still failing, check Node.js version
node --version  # Must be v20.19.0+

# Install specific Node version with nvm:
nvm install 20
nvm use 20

MongoDB not connecting

# Check MongoDB is running
sudo systemctl status mongod

# Start MongoDB
sudo systemctl start mongod

# Check connection
mongosh mongodb://127.0.0.1:27017/LibreChat

# If connection refused, check MONGO_URI in .env

Meilisearch not working

# Start Meilisearch with correct key
meilisearch --master-key="DrhYf7zENyR6AlUCKmnz0eYASOQdl6zxH7s7MKFSfFCt" --db-path ./meili_data

# Verify it's running
curl http://127.0.0.1:7700/health
