# Examples


metaBuilder examples are builder definitions with source
fixtures, self-documentation, tests, materialization plans, and
generated artifacts.

- [Node service example](/metaBuilder/examples/node-service) - Guided Node service builder tour: runnable package, HTTP service descriptor, runtime unit, dependency graph, and materialization plan.
- [C code generation example](/metaBuilder/examples/c-codegen) - Guided C codegen builder tour: schema input, generated C sources, static library, CLI, descriptors, dependency graph, and materialization plan.
- [Bridge example](/metaBuilder/examples/bridge) - Relates the shipped builder kinds — Node service, C code generation, OCI image, and IDL — through kernel-checked ornament, effect, and list-computation theorems.
- [IDL example](/metaBuilder/examples/idl) - IDL example: multi-language protobuf code generation via the IdlBuilder ornament and internalized program interpreters.
- [OCI image example](/metaBuilder/examples/oci-image) - Guided OCI image builder tour: busybox layer, digest-chain assembly steps, image descriptor, smoke-test evidence, and materialization plan.
