Error Handling

This details how to handle errors in ambiorix.

When an error occurs server-side it should send the client a response with a status starting in 5 to indicates that was the case.

Default

By default ambiorix uses the following handler on error.

\(req, res){
  response_500()
}

Global

One can specify the handler to use when an error occurs anywhere in the application.

app$error <- \(req, res){
  res$status(500L)
  res$send("There was a server error :(")
}

Route Specific

Alternatively one can specify errors specific to certain routes, if these are not specified the global handler (above) is used.

app$get("/error", \(req, res){
  print(eRrOr)
}, \(req, res){
  res$send("This is an error on /error", status = 500L)
})
