Question 1

How to set up Better Errors for a Sinatra or non-Rails app?

Accepted Answer

Insert BetterErrors::Middleware into your Rack stack and set BetterErrors.application_root. Refer to the wiki for framework-specific instructions, as it requires manual configuration compared to Rails' out-of-the-box setup.

Question 2

Why isn't Better Errors showing on my remote development server?

Accepted Answer

Better Errors is configured for localhost by default for security. You need to adjust access rules via the wiki, but this is discouraged due to potential exposure of sensitive data.

Question 3

Better Errors vs using Pry for debugging in Rails?

Accepted Answer

Better Errors offers an in-browser interface with error-specific context like variable inspection, while Pry is a general-purpose REPL. Better Errors is better for immediate error diagnosis, but Pry provides more flexible interactive sessions.

Question 4

How to fix 'Session Expired' messages with Unicorn?

Accepted Answer

This occurs due to multi-worker context switching. Reduce workers to one in development or switch to a single-process server like Webrick, as noted in the README's compatibility section.

Question 5

What editors are supported for the click-to-open links?

Accepted Answer

Better Errors uses the EDITOR environment variable and supports various editors via configuration; default is TextMate protocol. Check the wiki for setup instructions for editors like VS Code or Sublime Text.

Question 6

Is it safe to use Better Errors in a team with shared development environments?

Accepted Answer

It can pose risks if not properly configured, as it exposes debugging data. Ensure it's only in development and restrict access via IP whitelisting or similar methods described in the wiki.
