redb.Route.JsonTransform

Declarative JSON-to-JSON transformation with JSONata — the analog of Camel's jslt / jolt / jsonata components — on the native .NET engine Jsonata.Net.Native (no JavaScript, no JVM). Field-to-field mapping with renaming, nesting, array unwrapping and defaults, without writing a template for the whole document.

.TransformJson("Transforms/order-to-shipment.jsonata")          // file, compiled once, cached
.TransformJson(TextSource.Inline("""
    { "id": orderId, "to": { "city": address.city }, "skus": items.sku, "tenant": $headers.tenant }
    """))
.TransformJson("Transforms/x.jsonata", JsonTransformOutput.Node) // JsonNode body instead of text
Rule Why
A string argument is a locator (file relative to JsonTransformOptions.BaseDirectory, default AppContext.BaseDirectory, or assembly:Name/Path/file.jsonata); inline text is TextSource.Inline("..."). A string never has to be guessed as "path or text" — the same rule as templates and the expression language.
Compiled at route build. A missing file or a syntax error fails Start() with the specification name and the engine's message.
Input: the body as JSON text, byte[], Stream, a System.Text.Json tree, or a POCO (serialized camelCase). The step sits naturally after Unmarshal or straight after an HTTP consumer.
$headers and $properties are bound in the specification. The same names the payload templates use.
Output: JSON text with ContentType = application/json (default; Indent option), or a JsonNode (JsonTransformOutput.Node). An undefined result leaves a null body.

Options: services.AddJsonTransform(o => ...) or context.UseJsonTransform(o => ...) — BaseDirectory, Indent.

XML form (the node's shape in the Route-XML catalog; the XML loader itself is not shipped yet): <transformJson spec="transforms/order-to-shipment.jsonata"/> or the specification as the element's text (CDATA); output="string|node".
