We recommend signing up for a Sentry account and configuring DocSpring to send error reports.

Sentry can be configured using two optional environment variables:

• SENTRY_DSN : For backend errors (from Ruby on Rails)
• SENTRY_JS_DSN : For frontend errors (from JavaScript in the browser)

Sentry is open source, so you can also set up a self-hosted instance:

Self-Hosted Sentry

Once you are logged in, click “Create New Project”. The platform choice doesn’t really matter here, but you can choose “Rails”:

Give your project a name, then click “Create Project”:

Copy this “DSN” string:

• Set the SENTRY_DSN environment variable to this DSN string.
• You have a few options for SENTRY_JS_DSN
  • Set this to the same value as SENTRY_DSN if you want to use a single Sentry project to track both backend and frontend errors
  • Create a new Sentry project and use a separate DSN for SENTRY_JS_DSN
  • Leave SENTRY_JS_DSN to ignore frontend errors
