Code Generation (cosmosgen)

The cosmosgen package orchestrates multi-target code generation from protobuf sources, including Go code, TS clients, composables, and OpenAPI output.

For full API details, see the cosmosgen Go package documentation.

When to use

• Run full generation pipelines from application services.
• Configure selective outputs (Go only, TS only, OpenAPI only, etc.).
• Check tool availability and maintain buf-related configuration.

Key APIs

• Generate(ctx, cacheStorage, appPath, protoDir, goModPath, frontendPath, options...)
• WithGoGeneration()
• WithTSClientGeneration(out, tsClientRootPath, useCache)
• WithOpenAPIGeneration(out, excludeList)
• DepTools() []string

Example

package main

import (
    "context"
    "log"
    "os"
    "path/filepath"

    "github.com/ignite/cli/v29/ignite/pkg/cache"
    "github.com/ignite/cli/v29/ignite/pkg/cosmosgen"
)

func main() {
    storage, err := cache.NewStorage(filepath.Join(os.TempDir(), "ignite-cache.db"))
    if err != nil {
        log.Fatal(err)
    }

    err = cosmosgen.Generate(
        context.Background(),
        storage,
        ".",
        "proto",
        "github.com/acme/my-chain",
        "./web",
        cosmosgen.WithGoGeneration(),
        cosmosgen.WithOpenAPIGeneration("./api/openapi.yml", nil),
    )
    if err != nil {
        log.Fatal(err)
    }
}
