How To Enable Decorators in TypeScript

Last updated on 14 Feb, 2023

In order to use or try Decorators in TypeScript, we need to enable it. Enabling Decorators can be done from tsconfig.json file.

If the tsconfig.json file has been created using tsc init command, the file would have a default configuration. The file also has many configurations that are commented.

One such commented option is experimentalDecorators. Uncomment the line that contains experimentalDecorators json property and ensure that its value is true.

Doing the above step will enable Decorators in TypeScript.
