General Application Settings
Core Application Settings
These variables control the core behaviour and environment of the application.
This does not need to be updated if using the provided Docker Compose file. If you change the ports here, make sure you update the relevant ports in the Docker Compose files.
| Environment Variable | Description | Type | Default Value |
|---|---|---|---|
BACKEND_PORT | Port the main backend service will listen on. | number | 3030 |
METRICS_PORT | Port for Prometheus metrics. | number | 9464 |
FRONTEND_URL | The base URL of the frontend application. | string (URL) | http://localhost:3000 |
BACKEND_URL | The base URL of this backend application. | string (URL) | http://localhost:3030 |
NUXT_PUBLIC_API_BASE | The base API endpoint for the frontend to communicate with the backend. See the comments in example.env for more information. | string (URL) | http://localhost:3030/api |
NUXT_PUBLIC_WS_BASE | The base ws endpoint for the frontend to communicate with the backend. See the comments in example.env for more information. | string (URL) | ws://localhost:3030 |
TIMEZONE | The timezone the application will operate in. | string (e.g., UTC, America/New_York) | UTC |
CUSTOM_PROMPT | A custom prompt to be used in conversation generation. | string | null |
ADVANCED_EXTRACTION | Extract text from files using the GPT4o vision capabilities (expensive but highest quality text extraction). | true or false | false |
MAX_WORKERS | Number of files that can be processed in parallel. | number | 3 |
NO_CHAT_FUNCTIONS | Set this to true if you do not want the chat to have access to function calls. This is useful for self-hosted models that either do not support function calling or get easily confused by it. | true or false | false |
INTERNAL_APP_COMMUNICATION_PORT | This is the port used for internal communication between the different backend services. It should not be changed unless you know what you are doing. | number | 3032 |
MAIN_APP_URL | This is the url for the services to connect to the main backend application. It should not be changed unless you know what you are doing. | string (URL) | https://acid_backend:3032 |
Serving Behind a Unique URL (e.g. a Reverse Proxy)
To host the service behind a reverse proxy or otherwise through a custom domain name, you will need to update the following variables: FRONTEND_URL, BACKEND_URL, NUXT_PUBLIC_API_BASE, and NUXT_PUBLIC_WS_BASE. Unfortunately, Microsoft login will not work when served on a unique URL, as the redirect address will not match what is registered in the EntraID portal. Make sure other components, such as storage, are also defined correctly with the correct URLs.
The app currently will not work if self-signed certificates are used. If using a reverse proxy, you will need to either serve the app using HTTP and tell the browser to treat the URL as secure (e.g. by adding it to the Insecure origins treated as secure option at chrome://flags/) OR, and preferably, make sure there is a signed certificate for the app (frontend and backend) and the storage service if also hosting this.
