@holmwell/errors v1.0.1

errors

Error handling for Node.js and Express

To install:

npm install @holmwell/errors

To use:

var errors = require("@holmwell/errors");

errors.log(Error)

Logs an Error object, or just a string, to the console. Future versions may log to some framework.

errors.guard(response, function (result))

Used for refactoring all your error conditionals. That is, it is for turning code like this:

db.circles.getAll(function (err, circles) {
    if (err) {
         handleError(err, res);
    }
    // <deal with circles>
});

Into this:

db.circles.getAll(guard(res, function (circles) {
    // <deal with circles>
}));

errors.handle(Error, response)

Primarily used internally, but you can also use it to send and an error code back to the Express client.

errors.middleware

Handle uncaught errors in your Express middleware stack. Typically this should be put near the end / bottom of your middleware.

var app = require('express')();
// Define routes, app.use(...), etc
app.use(errors.middleware);
