Route Handlers​

Route handlers are generated from all endpoints. The generated interface follows the naming convention of SDK functions.

const fastify = Fastify();const serviceHandlers: RouteHandlers = {  createPets(request,reply) {    reply.code(201).send();  },  listPets(request,reply) {    reply.code(200).send([]);  },  showPetById(request,reply) {    reply.code(200).send({      id:Number(request.params.petId),      name:'Kitty',    });  },};fastify.register(glue, { serviceHandlers });

export default {  input:'hey-api/backend',// sign up at app.heyapi.dev  output:'src/client',  plugins: [    // ...other plugins    {      name:'fastify',    },  ],};
