Bashio - Home Assistant Community Add-ons

Home Assistant Community Add-ons: Bashio

About

Bashio is a bash function library for use with Home Assistant add-ons.

It contains a set of commonly used operations and can be used to be included in add-ons to reduce code duplication across add-ons and therefore making it easier to develop and maintain add-ons.

Main goals:

• Reduce the number of operations needed in add-ons.
• Reduce the amount of code needed in add-ons.
• Make add-on code more readable.
• Providing a trusted and tested code base.

Quicker add-on development, by allowing you to focus on the add-on logic instead of other things.

Installation

The library is installed in the Home Assistant Community Add-ons base images and the official Home Assistant base images.

Currently available base images:

• Home Assistant Community Add-ons Alpine Base Image
• Home Assistant Community Add-ons Alpine Python Base Image
• Home Assistant Community Add-ons Debian Base Image
• Home Assistant Community Add-ons Ubuntu Base Image
• Official Home Assistant Alpine Docker Base Image
• Official Home Assistant Alpine Python Docker Base Image
• Official Home Assistant Debian Docker Base Image
• Official Home Assistant Raspbian Docker Base Image
• Official Home Assistant Ubuntu Docker Base Image

Using those images as the base for your Home Assistant add-on will provide this function library out of the box. Our base images are updated frequently and provide the minimal needed base image for a great add-on.

If you want to add Bashio to your own images, please take a look at the Dockerfile of the above base images to see how they are added at build time.

Configuration

Configuring a Bash script to use the Bashio library is fairly easy. Simply replace the shebang of your script file, from bash to bashio.

Before example:

#!/usr/bin/env bash
set -e

CONFIG_PATH=/data/options.json

USERNAME=$(jq --raw-output '.username // empty' $CONFIG_PATH)

echo "${USERNAME}"

After example with Bashio:

#!/usr/bin/env bashio

USERNAME=$(bashio::config 'username')

bashio::log.info "${USERNAME}"

Functions

Bashio has more than 250+ functions available: communicating with the Supervisor API, Have I Been Pwned, file system, logging, configuration handling and a lot more!

The best way to get around would be by looking at the different modules available in the lib folder. Each module has its own file, and each function has been documented inside the codebase.

Furthermore, Bashio is used by the Home Assistant Community Add-ons project, those add-ons will be a great resource of practical examples.

Known issues and limitations

• Some parts of the Supervisor API are not implemented yet.
