api-error-handler-revived

Forked from api-error-handler since there were unmerged 2016 pull requests

An error handler for JSON APIs, meant to be used with http-errors-style errors.

Installation

npm i api-error-handler-revived

Example

var errorHandler = require('api-error-handler-revived');
 
var api = new express.Router();
api.get('/users/:userid', function (req, res, next) {
 
});
 
api.use(errorHandler());
 
app.use('/api', api);

API

.use(errorHandler([options]))

Options:

• stack:
  • Description: Wether to show or not the stacktrace
  • Default: true
• log
  • Description: Wether to console.error the error object
  • Default: true
• suppressServer
  • Description: Wether to supress serverside (5xx) errors with a generic message
  • Default: true

Extra params

If you need to expose any other params, pass an extra property to the http-errors properties parameter:

createError(400, `There were errors validating sent data`, {extra: {errors: validationErrors}})

Errors

4xx errors are exposed to the client. Properties exposed are:

• message
• type
• name
• code
• status
• extra properties

5xx errors are, by default, not exposed to the client. Instead, they are given a generic message as well as the type.
