Community Hass.io Add-ons: Bashio

About

Bashio is an bash function library for use with Hass.io 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 an 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 Community Hass.io Add-ons base images and the official Hassio base images by Home Assistant.

Currently available base images:

• Community Hassio Add-ons Alpine Base Image
• Community Hassio Add-ons Alpine Python Base Image
• Community Hassio Add-ons Ubuntu Base Image
• Official Hassio Alpine Base Image
• Official Hassio Alpine Python Base Image
• Official Hassio Ubuntu Base Image
• Official Hassio Raspbian Base Image

Using those images as the base for your Hass.io add-on, will provide this function library out of the box. Our base images are updated frequently and provides 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 an 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 then 250+ functions available: communicating with the Hass.io 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 code base.

Further more, Bashio is used by the Community Hass.io Add-ons project, those add-ons will be a great resource of practical examples.

Known issues and limitations

• Some parts of the Hass.io API are not implemented yet.
