 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
+```typescript
 import { constants } from 'zlib';
 // somewhere in your initialization file
 await app.register(compression, { brotliOptions: { params: { [constants.BROTLI_PARAM_QUALITY]: 4 } } });
