Express Statuses

A very simple collection of statuses suitable to be used with the express-errorlog package.

• Install and use
• Statuses
  • Getting Statuses
  • Overriding Messages
  • Wrapping Errors
  • Multiple overrides
• License (MIT)

Install and use

Install as usual with NPM:

npm install --save express-statuses

Then use it in your express app!

var S = require('express-statuses');
...
app.get('/foobar', function(req, res, next) {
  next(S.BAD_REQUEST);
})

The application error handler will see an object containing the following:

app.use(function(err, req, res, next) {
  // err will be { status: 400, message: 'Bad Request' }
  ...
})

A handy collection of status codes can also be accessed via the C sub-object:

app.post('/collection', function(req, res, next) {
  ...
  res.sendStatus(S.C.CREATED);
})

Getting statuses

Statuses can be referenced by name:

S.NOT_FOUND;

Or can be accessed by status code:

S(404);

All returned statuses can be passed to next(...) as-is or (being functions) can be used to further customize what is passed to the error handler.

Customization and inclusion can be done in few ways:

Messages

Messages can be overridden by simply invoking a status as a function:

next(S.NOT_FOUND('Something is amiss'));

will result in the error handler receiving the following as its first parameter:

{
  "status": 404,
  "message": "Something is amiss"
}

Errors

Errors can be nested for further logging by the error handler:

try {
  ...
} catch (error) {
  next(S.BAD_REQUEST(error));
}

will result in the error handler receiving the following as its first parameter:

{
  "status": 400,
  "message": "Bad Request"
  "error": ... // reference to the error for logging
}

Multiple overrides

For better express-errorlog integration, a number of parameters can be specified as options:

next(S.UNAUTHORIZED({
  message: 'No way I am letting you in',
  details: { key: 'Some extra stuff here' }
  error: myCaughtException
}));

will result in the error handler receiving the following as its first parameter:

{
  "status": 400,
  "message": "No way I am letting you in",
  "details": { "key": "Some extra stuff here" }
  "error": // reference to myCaughtException
}
