@metaobjectsdev/render

Logic-less, deterministic text render engine (Mustache) for MetaObjects templates — provider-resolved partials, format-driven escaping, and stable, snapshot-testable output. Zero runtime dependency on the rest of MetaObjects.

Part of the MetaObjects monorepo.

Install

npm install @metaobjectsdev/render

What it provides

• render() — render a MetaObjects template.output / template.prompt against a typed payload. Deterministic and cache-stable (no whitespace drift that would silently break exact-prefix prompt-cache hits), so output is snapshot-testable.
• Provider-resolved partials + format-driven escaping (text / html / xml / csv / json / markdown).
• verify() — a build-time drift check that every {{field}} referenced by a template resolves to a field on its payload value-object; a renamed field fails the build instead of silently degrading a prompt.

This engine backs the prompt-construction pillar — the generated render<Name>() helpers emitted by @metaobjectsdev/codegen-ts wrap it. See the metaobjects-prompts skill and the repo docs/ for authoring template.* and payload VOs.
