Installation

Jelly Music App can be installed as a dedicated desktop app, available on our GitHub release page. You can also get the latest production build from there and deploy it on your web server by placing the archived folder's contents in a web-accessible directory.
It's also available as a docker image for easy deployment, see docker details below.

Yarn (npm i -g yarn) is required if you wish to build the project or run the development server yourself.

#### Build from Source

• Clone the repository:

    git clone https://github.com/Stannnnn/jelly-app.git
    ``
Install dependencies:
    `bash
    yarn
    `
Build the production files:
    `bash
    yarn build
    `
Deploy the contents of the dist folder to a web-accessible directory.
Alternatively, you can run the development server directly: yarn dev or yarn dev:nocache
If you wish to use a base path for the application other than root (/), you must build it manually while setting URL_BASE_PATH to your preferred base path.
Leave the configuration as the default, or change config.json as needed. Configurations are explained on the App Configuration Section.
The config.json file can be changed directly in the built application afterwards. There is no need to rebuild if only changing a configuration variable.
Docker
You can easily host Jelly Music App using Docker with the prebuilt image from ghcr.io:
#### Pull the docker image

#### Run the docker image

Docker image can also be run in the background by adding the -d flag docker run -d ...
#### Run the docker image with configuration variables

E.g: ghcr.io/stannnnn/jelly-music-app:latest

#### Docker Container Build

You can also build Jelly Music App using Docker.

• Build the Docker image:

`bash docker run --rm \ -e DEFAULT_JELLYFIN_URL=https://demo.jellyfin.org/stable \ -e LOCK_JELLYFIN_URL=false \ -p 80:80 jelly-music-app:latest `

#### Docker Compose

For easier container management, you can use Docker Compose. A docker-compose.yaml file is provided in the repository with sensible defaults.

• Copy the example environment file and customize it for your setup:

• Edit the .env file with your Jellyfin server URL and preferences:

• JELLYAPP_PORT: External port to expose (default: 80)
• JELLYAPP_DEFAULT_URL: Default Jellyfin server URL (default: https://demo.jellyfin.org/stable)
• JELLYAPP_LOCK_URL: Lock the Jellyfin URL input (default: false)

App Configuration

App configuration can be modified by editing the config.json file during the build process or in the release files. When using Docker, configurations can be provided as environment variables. The available configuration options are as follows:

• DEFAULT_JELLYFIN_URL: Sets the default Jellyfin server URL loaded on first app access if no URL is stored in Local Storage.
• LOCK_JELLYFIN_URL: If set to true, removes the URL input field and enforces the default URL (DEFAULT_JELLYFIN_URL) for all connections, ideal for self-hosted instances tied to a single server.
