Component configuration defines buildable and deployable units stored in components/<id>.json.

Fields

Required Fields

• id (string): Unique component identifier, derived from local_path directory name (lowercased)
• local_path (string): Absolute path to local source / git checkout directory, ~ is expanded
• remote_path (string): Remote path relative to project base_path (the deploy target)
• build_artifact (string): Build artifact path relative to local_path, must include filename

Important: local_path must point to a git repository / source checkout, not the production deploy target. The deploy target is derived from project.base_path + component.remote_path. If local_path points to the deployed directory, builds will run inside production and uncommitted-changes checks will fail (the directory isn’t a git repo). This is a common misconfiguration after server migrations.

Optional Fields

• name (string): Human-readable component name, defaults to id
• extract_command (string): Command to execute after artifact upload, runs inside target directory
  • Supports template variables: {artifact}, {targetDir}
• version_targets (array): List of version detection patterns
  • file (string): Path to file containing version (relative to local_path)
  • pattern (string): Regex pattern to extract version (first capture group)
• changelog_target (string): Path to changelog file (relative to local_path)
• extensions (object): Extension-specific settings
  • Keys are extension IDs (e.g., "wordpress", "rust")
  • Values are extension setting objects
• scripts (object): Component-owned shell commands for extension-shaped capabilities
  • Supported keys: lint, test, build, bench, trace
  • Each value is an array of shell commands run sequentially in local_path
  • Resolution order is scripts.<capability> first, then linked extension support, then not-applicable
  • Scripts receive the same runner env paths (HOMEBOY_COMPONENT_ID, HOMEBOY_COMPONENT_PATH, HOMEBOY_RUN_DIR and sidecar file vars when relevant) as extension runners, with HOMEBOY_EXTENSION_ID=component-script
  • Use scripts.build, not build_command; build_command is still only a diagnostic output field.
• release (object): Component-scoped release configuration
  • enabled (boolean): Whether release pipeline is enabled
  • steps (array): Release step definitions
  • settings (object): Release pipeline settings

Runtime Requirements

Important: local_path must point to a git repository / source checkout, not the production deploy target. The deploy target is derived from project.base_path + component.remote_path. If local_path points to the deployed directory, builds will run inside production and uncommitted-changes checks will fail (the directory isn’t a git repo). This is a common misconfiguration after server migrations.

local_path vs remote_path

local_path (source)                          remote_path (deploy target)
┌──────────────────────────┐                ┌──────────────────────────────────────────┐

• file (string): Path to file containing version (relative to local_path)
• pattern (string): Regex pattern to extract version (first capture group)

homeboy component env reports runtime requirements in a generic runtimes map:

      }
    ]
  }
}

Version Target Format

Runtime IDs are extension-owned strings. source is component for component config or detector output and extension:<id> for extension-provided defaults. Legacy component extension settings such as { "php": "8.2", "node": "22" } are still parsed for compatibility; new config should use runtimes.

pre_version_bump_commands (array of strings): Commands to run BEFORE version targets are updated

• Keys are extension IDs (e.g., "wordpress", "rust")
• Values are extension setting objects

Extract Command Context

post_version_bump_commands (array of strings): Commands to run AFTER version files are updated

• Supported keys: lint, test, build, bench, trace
• Each value is an array of shell commands run sequentially in local_path
• Resolution order is scripts.<capability> first, then linked extension support, then not-applicable
• Scripts receive the same runner env paths (HOMEBOY_COMPONENT_ID, HOMEBOY_COMPONENT_PATH, HOMEBOY_RUN_DIR and sidecar file vars when relevant) as extension runners, with HOMEBOY_EXTENSION_ID=component-script
• Use scripts.build, not build_command; build_command is still only a diagnostic output field.

post_release_commands (array of strings): Commands to run after the release pipeline completes

• enabled (boolean): Whether release pipeline is enabled
• steps (array): Release step definitions
• settings (object): Release pipeline settings

Storage Location

Setting local_path to the same directory as the deploy target is a misconfiguration — builds would run in production and homeboy deploy would fail uncommitted-changes checks.

• Supports template variables: {artifact}, {targetDir}
