Write Handlebars template expressions for Celigo integrations -- dynamic values in mappings, HTTP bodies, SQL queries, URIs, and filters. Use when building any resource configuration that needs computed, conditional, or formatted field values.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<!-- TIER:1 -->
# 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.
## Where Handlebars Are Used
### Mapping extracts
In import `mappings[].extract` fields, Handlebars concatenates, transforms, or conditionally selects values. The context is the current record.
### HTTP request templates

How to install
mdr add celigo/ai/writing-handlebars@sha256:11d7bcd65b705e96The line at the top of this page pins the label git:20261017.e0e159f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
