Firebase CTL

Firebase CTL is a tool intended to automate and source control the remote configurations for firebase projects.

To make it work, we require a service account file in the machine that runs the tool, and the path to said file be provided in the environment variable,GOOGLE_APPLICATION_CREDENTIALS.

It offers the following facilities

Dump existing conditions and parameters to a file

This command will query the remote-config REST API to get the configurations and dump it to the directory

firebase-ctl get remote-config --output-dir output/

The output will be of the following structure

 output
 |__conditions
    |__conditions.json
 |__parameters
    |__parameters.json

Validate a directory whether the structure is valid

Here, the user has two options

• If the GOOGLE_APPLICATION_CREDENTIALS environment variable is not provided, the tool just performs a validation to ensure structural integrity.
• If the GOOGLE_APPLICATION_CREDENTIALS environment variable is provided, the tool validates the configuration for structural correctness. Further it also performs a validation by making a call to the firebase API which makes a dry-run without applying the configuration.

The command is as follows

firebase-ctl validate remote-config --input-dir local-dir

The users can create multiple files under the parameters directory according to the feature set. However, uniqueness needs to be maintained across all the keys present in the files in the parameters directory.

Find the diff between the source, and the current remote version

This command shows the diff for both conditions and parameters in red and green colors.

firebase-ctl diff remote-config --config-dir local-dir

Apply the config

This command applies the remote-config in the input-dir

firebase-ctl apply remote-config --input-dir input-dir
