 Now we can complete the process by injecting the `'CONFIG_OPTIONS'` provider into the `ConfigService`.

 By default, `@fastify/compress` will use Brotli compression (on Node >= 11.7.0) when browsers indicate support for the encoding. While Brotli can be quite efficient in terms of compression ratio, it can also be quite slow. By default, Brotli sets a maximum compression quality of 11, although it can be adjusted to reduce compression time in lieu of compression quality by adjusting the `BROTLI_PARAM_QUALITY` between 0 min and 11 max. This will require fine tuning to optimize space/time performance. An example with quality 4: 
 
 ```typescript
-import { constants } from 'zlib';
