NextJS: Disable Sentry During Development

[FroeMic]

I want to disable sentry on my Next (App Router, Instrumentalization) app during development (i.e., when running next dev or when process.NODE_ENV === "development".

Has anyone figured out how to do this? I couldn't find a clear answer in the docs.

Sentry.init() has an enabled option. You can do enabled: process.env.NODE_ENV !== 'development'

I assume you mean !== 'development.

This, I think, works, but

a) Still produces a warning [@sentry/nextjs] WARNING: You are using the Sentry SDK with next dev --turbo if run with turbo, but I can just ignore this warning

b) All of Sentry and openTelementry still appears in the bundle for pages hugely increasing the build speed of every page.

Correct. Thank you! Updated my original response.

OP is asking to disable/enable instrumentation for which there are options.

You are asking for conditional imports because imports will be resolved and bundled no matter whether Sentry is enabled or not. This is not a Sentry specific topic. You could build your own solution by building a wrapper around the Sentry APIs that is treeshakable in dev mode but mileage may vary.
