Quickstart Guide

Installation

Clone the repository:
terminal
```
git clone https://github.com/1811-Labs-LLC/BuilderKit-Starter.git [YOUR_APP_NAME]
 
cd [YOUR_APP_NAME]
 
git checkout multillm-chatgpt
```
Remove the origin remote to ensure that you can work locally without pushing the changes back to the original repository.
terminal
```
git remote remove origin
```
However, note that after removing the remote, you won't be able to switch between the branches, so you'll need to clone the repository again if you want to work on another branch.
Install dependencies:
terminal
```
npm install
```

Setup Supabase

If you have not setup the supabase yet, go through the detailed documentation to set up the supabase for BuilderKit.ai. Make sure that you are creating the user table as mentioned in the supabase setup doc as it is required for the tool.

Create MultiLLM ChatGPT Table in Supabase:

sql

-- Create a table for MultiLLm ChatGPT
create table multillm_chatgpt (
   id uuid not null default uuid_generate_v4(),
   created_at timestamp with time zone not null default now(),
   user_id uuid null,
   model text null,
   title text null,
   chat_history jsonb null,
   constraint multillm_chatgpt_pkey primary key (id),
   constraint multillm_chatgpt_user_id_fkey foreign key (user_id) references users (id)
);
 
-- Set up Row Level Security (RLS)
alter table multillm_chatgpt
enable row level security;
 
create policy "Users can insert their own row." on multillm_chatgpt
for insert with check (auth.uid() = user_id);
 
create policy "Users can update own row" on multillm_chatgpt
for update using (auth.uid() = user_id);
 
create policy "Users can read own row" on multillm_chatgpt
for select using (auth.uid() = user_id);
 
-- Optional: Add policy to allow users to delete their own row
create policy "Users can delete own row" on multillm_chatgpt
for delete using (auth.uid() = user_id);

For all the tables, we enable the RLS policy by default with necessary permissions as mentioned in the script.
