query projects

Use the moon query projects sub-command to query information about all projects in the project graph. The project list can be filtered by passing a query statement as an argument, or by using options arguments.

# Find all projects
$ moon query projects

# Find all projects with an id that matches "react"
$ moon query projects --id react
$ moon query projects "project~react"

# Find all projects with a `lint` or `build` task
$ moon query projects --tasks "lint|build"
$ moon query projects "task=[lint,build]"

By default, this will output a list of projects in the format of <id> | <source> | <stack> | <type> | <language> | <description>, separated by new lines. If no description is defined, "..." will be displayed instead.

web | apps/web | frontend | application | typescript | ...

The projects can also be output in JSON by passing the --json flag. The output has the following structure:

{
	projects: Project[],
	options: QueryOptions,
}

Affected projects​

This command can also be used to query for affected projects, based on the state of the VCS working tree. For advanced control, you can also pass the results of moon query touched-files to stdin.

# Find all affected projects
$ moon query projects --affected

# Find all affected projects using the results of another query
$ moon query touched-files | moon query projects --affected
