# Server configuration: 
##########################

# The server will listen to localhost:3080 by default. You can change the target IP as you want. 
# If you want to make this server available externally, for example to share the server with others 
# or expose this from a Docker container, set host to 0.0.0.0 or your external IP interface. 
# Tips: Setting host to 0.0.0.0 means listening on all interfaces. It's not a real IP.  
# Use localhost:port rather than 0.0.0.0:port to access the server. 
# Set Node env to development if running in dev mode.
HOST=localhost
PORT=3080
NODE_ENV=production 

# Change this to proxy any API request. 
# It's useful if your machine has difficulty calling the original API server.

# Change this to your MongoDB URI if different. I recommend appending LibreChat. 
MONGO_URI=mongodb://127.0.0.1:27017/LibreChat

# To use Azure with this project, set the following variables. These will be used to build the API URL.

# You should also consider changing the `OPENAI_MODELS` variable above to the models available in your instance/deployment.
# Note: I've noticed that the Azure API is much faster than the OpenAI API, so the streaming looks almost instantaneous.

# PaLM (Google) Endpoint: 
##########################

# PaLM 2 Client (via Google Cloud Vertex AI API)
# Steps:
    # Enable the Vertex AI API on Google Cloud:
        # https://console.cloud.google.com/vertex-ai
    # Create a Service Account:
        # https://console.cloud.google.com/projectselector/iam-admin/serviceaccounts/create?walkthrough_id=iam--create-service-account#step_index=1
    # Make sure to click 'Create and Continue' to give at least the 'Vertex AI User' role.
    # Create a JSON key, rename as 'auth.json' and save it in /api/data/.
# Alternatively
    # Uncomment below PALM_KEY and set as "user_provided" to allow the user to provide a Service Account key JSON from the UI.
    # They will follow the steps above except for renaming the file.
# Leave blank or omit to disable this endpoint

# Search: 
##########################

# Requires the installation of the free self-hosted Meilisearch or a paid Remote Plan (Remote not tested) 
# The easiest setup for this is through docker-compose, which takes care of it for you. 
SEARCH=false

# REQUIRED FOR SEARCH: MeiliSearch Host, mainly for the API server to connect to the search server. 
# Replace '0.0.0.0' with 'meilisearch' if serving MeiliSearch with docker-compose. 
MEILI_HOST=http://0.0.0.0:7700

# Replace '0.0.0.0' with 'meilisearch' if serving MeiliSearch with docker-compose. 
MEILI_HTTP_ADDR=0.0.0.0:7700

# REQUIRED FOR SEARCH: In production env., a secure key is needed. You can generate your own. 
# This master key must be at least 16 bytes, composed of valid UTF-8 characters. 
# MeiliSearch will throw an error and refuse to launch if no master key is provided, 
# or if it is under 16 bytes. MeiliSearch will suggest a secure autogenerated master key.
# Using docker, it seems recognized as production so use a secure key.
# This is a ready made secure key for docker-compose, you can replace it with your own.
