Fork of lobe-chat v1.11.8

Description

Quick and dirty fork to enable lobe-chat to send ComfyUI api request + receive image link.
Secondary : Allow to have custom background image based on session id, just use a .png with session id name, from your url. (public/Bjornulf_backgrounds/16a174d5-928f-42e0-b1a7-3bb329a1bfa2.png) -Require restart to take effect-

Installation (for example with bun, but can use npm or whatever...)

Tested with Node v21.7.0, bun 1.0.30. (So you can nvm install v21.7.0 for example, and curl -fsSL https://bun.sh/install | bash -s "bun-v1.0.30")

git clone https://github.com/justUmen/Bjornulf_lobe-chat
cd Bjornulf_lobe-chat
bun install
bun run build

Start lobe-chat (for example with bun, but can use npm or whatever)

bun run start

And the server will be running on http://localhost:3210, use the browser of your choice.

Examples

ComfyUI

Background

Details

Need to use my Comfyui custom nodes : https://github.com/justUmen/ComfyUI-BjornulfNodes
Can use my JSON workflows in the public/Bjornulf_API/ folder to send to the ComfyUI, like for example sd15.json (Warning : You need to launch it manually at least one time before using it in lobe-chat.
It is using a link output/BJORNULF_API_LAST_IMAGE.png created by my custom node comfyui, that need to be used in the workflow. The generated image is then copied using this link to the public/generated/ folder inside lobe-chat.

Todo

If used with LLM, it also sends the local image link as useless tokens. (Not a huge waste, but a waste nevertheless.)

Optional but recommended :

Lobechat is using by default storage in browser, but you can use a database to store the chat history. Here is a quick guide to use PostgreSQL : - You can also use the docker but I don't.-

1 - Install PostgreSQL

sudo apt install postgresql

2 - Connect to PostgreSQL as a superuser:

psql -U postgres

sudo -i -u postgres
psql

3 - Inside the PostgreSQL shell, create a new database, user, and grant privileges:

CREATE DATABASE lobe_chat_db;

4 - Create a new user:

CREATE USER youruser WITH PASSWORD 'yourpassword';

5 - Grant all privileges on the 'lobe_chat_db' database to the youruser' user:

GRANT ALL PRIVILEGES ON DATABASE lobe_chat_db TO youruser;

6 - Connect to the 'lobe_chat_db' database:

\c lobe_chat_db

7 - Grant usage and create privileges on the public schema to the 'youruser' user:

GRANT USAGE, CREATE ON SCHEMA public TO youruser;

8 - Grant all privileges on all tables in the public schema to the 'youruser' user:

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO youruser;

9 - Grant all privileges on all sequences in the public schema to the 'youruser' user:

GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA public TO youruser;

10 - Set the default privileges for the 'youruser' user to create tables and sequences:

ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL ON TABLES TO youruser;
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT ALL ON SEQUENCES TO youruser;

11 - Leave psql:

\q

Example of configuration .env file in the root of your project for local database :

NEXT_PUBLIC_SERVICE_MODE=server
DATABASE_DRIVER=node
DATABASE_URL=postgres://youruser:yourpassword@localhost:5432/lobe_chat_db
KEY_VAULTS_SECRET=MgMzt2U+lKwSCN9enMYmyvVRTFzsb60db8127035
NEXT_AUTH_SECRET=RDD/HFZTSufylb61eb1117095t3KuO1FrHnviMATqAa=
NEXT_AUTH_SSO_PROVIDERS=github
GITHUB_CLIENT_ID=Iw23lx1kdsIoieHxufr
GITHUB_CLIENT_SECRET=25b7fff7a065b6c63e2e5d19c7adb60db1217075
ACCESS_CODE=thispasswordisverylong

Generate KEY_VAULTS_SECRET and NEXT_AUTH_SECRET with openssl rand -base64 32.
GITHUB_CLIENT_ID and GITHUB_CLIENT_SECRET are obtained by creating a new OAuth App on GitHub.
You can use http://localhost:3210 as the homepage URL and the Authorization callback URL.
