Migration from Swagger

Migration from Swagger


npx @nestia/migrate

@nestia/migrate converts swagger.json file to:

When you run npx @nestia/migrate command, @nestia/migrate will analyze your swagger.json file, and generate a NestJS project into the output direcory. If you're considering to migrate your backend project to NestJS, @nestia/migrate will be a good starting point.

Of course, even if you're not considering to adapt NestJS, you can generate standalone SDK library and Mockup Simulator from the swagger.json file instead. Just run the npx @nestia/migrate command and build the SDK library and Mockup Simulator, then frontend (client) developers may get satisfied.


Left is NestJS server code, and right is client (frontend) code utilizing SDK


npx @nestia/migrate 
  --mode [nest|sdk] 
  --input [input] 
  --output [output] 
  --simulate [true|false]
  --e2e [true|false]
npx @nestia/migrate --mode nest --input swagger.json --output directory --simulate false --e2e false
npx @nestia/migrate --mode sdk --input swagger.json --output directory --simulate true --e2e true

You can specify migration options like above.

However, don't worry anything. If you omit something, prompt inquiries will help you.
