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= HF_ACCESS_TOKEN= ``` ## Duplicating to a Space Create a `DOTENV_LOCAL` secret to your space with the following contents: ``` MONGODB_URL= HF_ACCESS_TOKEN= ``` Where the contents in `<...>` are replaced by the MongoDB URL and your [HF Access Token](https://huggingface.co/settings/tokens). ## Running Local Inference Both the example above use the HF Inference API or HF Endpoints API. If you want to run the model locally, you need to run this inference server locally: https://github.com/huggingface/text-generation-inference And add this to your `.env.local`: ``` MODELS=`[{"name": "...", "endpoints": [{"url": "127.0.0.1:8080/generate_stream"}]}]` ``` ## 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.
