# CommonJS (CJS) | Sentry for Nest.js

Are you unsure if you should use this installation method? Review our [installation methods](https://docs.sentry.io/platforms/javascript/guides/nestjs/install.md).

Most node applications today are either written in or compiled to CommonJS (CJS), which uses `require()` to load modules. Nest.js, by default, transpiles your TypeScript code into CommonJS.

You can follow the installation instructions in the SDK's [Quick Start guide](https://docs.sentry.io/platforms/javascript/guides/nestjs.md).
