Component monikers

A component moniker identifies a specific component instance in the component tree using a topological path of child names.

This section describes the syntax used for displaying monikers to users.

Child names

Parents assign names to each of their children. Dynamically created children are arranged by their parent into named collections.

A child name is represented by the child's static name (assigned in a component manifest), or collection name and the runtime-assigned child name delimited by :.

Syntax: {name} or {collection}:{name}


  • carol
  • support:dan - The collection support with the child dan.

The {name} and {collection} must follow the regex [-_.a-z0-9]{1,100}. That is, a string of 1-100 of the following characters: a-z, 0-9, _, ., -.

See the component manifest reference for more details.


Represented by the minimal sequence of child names encountered when tracing downwards to the target delimited by a / (slash).

Monikers do not support upward traversal (i.e. ..) (from child to parent).


  • . - self - no traversal needed
  • carol - a child - traverse down carol
  • carol/sandy - a grandchild - traverse down carol then down sandy
  • support:dan - a child - traverse down into collection child support:dan
