setting status code

[sprzybylski]

Google APIs are returning error messages in following format:

{
  errors: [{
       domain: 'global',
       reason: 'authError',
       message: 'Invalid Credentials',
       locationType: 'header',
       location: 'Authorization'
  }],
  code: 401,
  message: 'Invalid Credentials'
}

statusCode is here under code property not status.

What does this have to do with this module?

[sprzybylski]

if (err.status) res.statusCode = err.status;

This module only accepts Error objects of a specific format. Typically err.code is internal system codes like ENOENT in node.js land. This module will not cater to looking under the code property because it does not fit with the standards of the node.js ecosystem.

Ok, thanks.

Your best bet if you want to use this module as your handler and throw those objects is to add a pre-processor before this module:

app.use(function(err,req,res,next){
  if (typeof err.code === 'number') {
    // copy Google API code to status property
    err.status = err.code;
  }
  next();
})
app.use(errorHandler())
