Overview

Choose one of the following options for your open source data layer:

• use the official Chainlit data layer (PostgreSQL + asyncpg)
• leverage a community-based data layer
• or build your own!

​

Official data layer

When using the official data layer, just add the DATABASE_URL variable to your .env and a cloud storage configuration if relevant.

​

Community data layers

For community data layers, you need to import the corresponding data layer in your chainlit app. Here is how you would do it with SQLAlchemyDataLayer:

import chainlit as cl

from chainlit.data.sql_alchemy import SQLAlchemyDataLayer

@cl.data_layer
def get_data_layer():
    return SQLAlchemyDataLayer(conninfo="...")

​

Custom data layers

Follow the reference for an exhaustive list of the methods your custom data layer needs to implement.
