# Chat UI
A chat interface using open source models, eg OpenAssistant.
## Launch
```bash
npm install
npm run dev
```
## Environment
Default configuration is in `.env`. Put custom config and secrets in `.env.local`, it will override the values in `.env`.
Check out [.env](./.env) to see what needs to be set.
Basically you need to create a `.env.local` with the following contents:
```
MONGODB_URL=<url to mongo, for example a free MongoDB Atlas sandbox instance>
MODEL_ENDPOINTS=`[{
"endpoint": "https://api-inference.huggingface.co/models/OpenAssistant/oasst-sft-4-pythia-12b-epoch-3.5",
"authorization": "Bearer <hf_token>",
"weight": 1
}]`
```
Where the contents in `<...>` are replaced by the MongoDB URL and your [HF Access Token](https://huggingface.co/settings/tokens).
## Duplicating to a Space
Create a `DOTENV_LOCAL` secret to your space with the following contents:
```
MONGODB_URL=<url to mongo, for example a free MongoDB Atlas sandbox instance>
MODEL_ENDPOINTS=`[{
"endpoint": "https://api-inference.huggingface.co/models/OpenAssistant/oasst-sft-4-pythia-12b-epoch-3.5",
"authorization": "Bearer <hf_token>",
"weight": 1
}]`
```
Where the contents in `<...>` are replaced by the MongoDB URL and your [HF Access Token](https://huggingface.co/settings/tokens).
## Building
To create a production version of your app:
```bash
npm run build
```
You can preview the production build with `npm run preview`.
> To deploy your app, you may need to install an [adapter](https://kit.svelte.dev/docs/adapters) for your target environment.
