Writing Handlebars Expressions

Handlebars is Celigo's template language for embedding dynamic values into resource configurations. Any string field that the platform evaluates at runtime can contain Handlebars expressions.

Concerns when writing Handlebars:

• Context -- where the expression runs determines what data is available and how output is treated
• Braces -- double {{ }} vs triple {{{ }}} controls output escaping
• Field access -- record. prefix in all contexts (AFE 2.0), @root for job/settings/connection, bracket notation for special characters
• Helpers -- 79 custom helpers for math, string manipulation, dates, encoding, regex, and more
• Block helpers -- #each, #if, #compare, #with for iteration and conditional logic
• Date/time -- moment.js format tokens with timezone support

Used across exports, imports, mappings, output filters, and APIs.
