codistill – 既存コードからSSOTを搾り出す Image: AI generated

既存プロジェクトにSSOTを適用したいがゼロから書き直せないなら、レガシーのGo/NestJS/FastAPIコードからOpenAPIとDDLを自動抽出したいなら――codistillが既存コードから仕様を搾り出す。

“We already have 200 endpoints”

codist scan --openapi ./my-project
FrameworkLanguageExtraction
GinGoRoutes, bindings, responses, middleware
NestJSTypeScriptDecorators, DTOs, guards, interceptors
FastAPIPythonRoutes, Pydantic models, dependencies
codist ddl ./migrations -o ./schema

codist sql next --repo ./repository --queries ./db/query

codist sql status

Existing code
  ↓ codist scan --openapi
  ↓ codist ddl
  ↓ codist sql next
OpenAPI + DDL + sqlc
  ↓ yongol validate
  ↓ yongol generate
SSOT-based codebase
