Manage errors in Restify
node.js, restify
Solution
- Handle your errors immediately, where they're generated. `next(err)` really means `res.send(err)`. It's not an alternative to `throw err`. If you need to log and shut down, pass it off to an error handling module instead of stuffing it in `next(err)` where it will be swallowed.
- `server.on('uncaughtException'...` is how you handle any errors that were thrown in middleware / routes. It works fine for that purpose, as long as you remember the first guideline. `'uncaughtException'` will not be triggered for `next(err)` calls.
- `formatters` are the way to customize error messages going out to the users. They're definitely not a viable alternative to dealing with errors in `uncaughtException`, because presumably, once you get there, you're sending the user the error you want them to see... not necessarily the error that was originally generated. See point 1.
- For errors unrelated to middleware, remember to use `process.on('uncaughtException'...`
Problem
How i can manage all error of my restful server build with Restify of NodeJS? For example internal errors, database errors, validate, required params, not founds, athorizeds... And uncaughtException and return custom response to browser? How i can design the share of data and errors between controllers? Thanks
