Modules descriptions

FastifyNestApplicationInitializer

Fastify NestJS application initializer.

Use in NestJS-mod

Use without options.

import { bootstrapNestApplication } from '@nestjs-mod/common';

  modules: {
    system: [
      FastifyNestApplicationInitializer.forRoot({
        staticConfiguration: {
          wrapFastifyAdapter: (fastifyAdapter: FastifyAdapter) => {
            fastifyAdapter.register(fmp);
          },
