libcodegen Skill

When to Use

• Generating JavaScript types from Protocol Buffer schemas
• Creating gRPC service stubs automatically
• Updating generated code after .proto changes
• Maintaining type consistency across microservices

Key Concepts

TypeGenerator: Generates JavaScript classes from protobuf message definitions with proper type annotations.

ServiceGenerator: Creates gRPC service stubs with method signatures matching the proto service definitions.

DefinitionGenerator: Generates type definitions for IDE support and documentation.

Usage Patterns

Pattern 1: Generate types from protos

import { TypeGenerator } from "@copilot-ld/libcodegen";

const generator = new TypeGenerator("./proto");
await generator.generate("./generated/types");

Pattern 2: Generate service stubs

import { ServiceGenerator } from "@copilot-ld/libcodegen";

const generator = new ServiceGenerator("./proto");
await generator.generate("./generated/services");

Integration

Run via make codegen after modifying .proto files. Output used by libtype and librpc.
