rust like result class

Create an iterator which evaluates the relative error exponential for each iterated value.

proptype validators for results instances

Error handling and extras for `.use` and `.run` methods of your Base apps. Modifies `.use` method to be able to 1) accept array of functions, 2) options object as second argument. Emits `error` event if some plugin fails.

Makes easy to use HTTP status and errors.

Converts result-first callbacks to classic (node.js-style) error-first callbacks with 3 lines of code. Useful when you want to promisify result-first APIs (like emitter.on). Inspired by [rfpify][] and probably used in it.

A TypeScript library implementing Rust-like error handling with Result, Ok, and Err types.

generates a string containing a message and trimmed stack from error

richer JavaScript errors, but without sprintf

Create error instances with a code, status, etc.

Allows you to customize the toString method of passed `err`. Also adds useful properties like `line`, `filename` and `column` to the `err` object.

tape error events for t.fail(msg)

Not so strongly typed error

Displays http status in browser, good for error handling.

Easily create an error with custom properties attached.

Collection of error handling utilities for JavaScript and TypeScript.

Extra err.stack entries for debuggability. Better than your plain 'if (err) { return cb(err) }'

Graceful error handling. Because core `domain` module is deprecated. This share almost the same API.

common error defines as JSON format

get rid of `if (err) throw err`
