Overview

Scopes component execution under a namespace key.

Behavior:

  • Extracts params from params (disable with shared_params: true)

  • Merges context into component context with priority

  • Wraps returned context under namespace key

  • Prefixes error paths with namespace

Examples:

Nested author creation

# params: { title: 'Hello', author: { name: 'John', email: '[email protected]' } }
namespace(:author, create_author)
# Inner receives: { name: 'John', email: '[email protected]' }
# Result context: { author: { author: <Author> } }
# Error paths: [:author, :email] instead of [:email]

Shared params for multiple processors

parallel(
  namespace(:cache, warm_cache, shared_params: true),
  namespace(:search, index_search, shared_params: true)
)
# Both receive full params; results namespaced separately

Sequential namespace accumulation

sequence(
  namespace(:author, validate_author),  # => { author: { validated: true } }
  namespace(:author, create_author)     # => { author: { validated: true, author: <Author> } }
)
