The high-level goal of @openinf/util-errors
is to serve as a Node.js package
containing essential utility error classes that take the form of those found
and used in Node.js core. We are constantly working to improve this repository,
so please feel free to contribute if you notice any omissions
or errors.
Thanks!
Supported Node.js Environments
- v4:Argon (Ar)
- v6:Boron (B)
- v8:Carbon (C)
- v10:Dubnium (Db)

@openinf/util-errors
runs on
supported versions of Node.js and is available via
npm
, pnpm
, or yarn
.
Using the npm CLI
See the official documentation for this command for more information.
npm i @openinf/util-errors
Using the pnpm CLI
See the official documentation for this command for more information.
pnpm add @openinf/util-errors
Using the Yarn 1 CLI (Classic)
See the official documentation for this command for more information.
yarn add @openinf/util-errors
To get started using the error classes provided by @openinf/util-errors
, all
that needs to be done is either import/require (depending on the module format)
the default export of the module or destructure the individual named error
classes exported.
import { hasOwn } from '@openinf/util-object';
import { MissingOptionError } from '@openinf/util-errors';
import infLog from '@openinf/inf-log';
function getLogger(logger, opts) {
if (!hasOwn(opts, 'scope')) {
throw new MissingOptionError('scope');
}
return new logger(opts);
}
const log = getLogger(infLog, infLog.defaultOpts);
log.info('Hello, World!');
Note: The example above does not demonstrate how to properly handle this error once thrown and would likely result in an uncaught exception.
Note: If you are in an environment where the CommonJS module loader
(require()
) is available, destructuring the individual error classes works
just as well.
- InvalidArgValueError
Thrown in case an invalid or unsupported value was passed for a given argument.
- InvalidArgTypeError
Thrown in case an argument of the wrong type was passed for a given argument.
- InvalidPropertyValueError
Thrown in case an invalid or unsupported value of an object property.
- InvalidPropertyTypeError
Thrown in case an invalid or unsupported value type for an object property.
- InvalidReturnPropertyValueError
Thrown in case a function does not provide a valid value for one of its returned object properties on execution.
- InvalidReturnPropertyTypeError
Thrown in case a function does not provide an expected value type for one of its returned object properties on execution.
- InvalidReturnValueError
Thrown in case a function does not return an expected valid value on execution.
- InvalidReturnTypeError
Thrown in case a function does not return an expected value type on execution, such as when a function is expected to return a promise.
- InvalidArgsNumberError
Thrown in case the number of arguments passed to a function is invalid.
- MissingOptionError
For APIs that accept options objects, some options might be mandatory. This error is thrown if a required option is missing.
- MissingArgsError
Thrown in case a required argument of an API was not passed.
This is only used for strict compliance with the API specification (which in some cases may accept
func(undefined)
but notfunc()
). In most native Node.js APIs,func(undefined)
andfunc()
are treated identically, and theERR_INVALID_ARG_TYPE
error code may be used instead.- UnhandledErrorError
Thrown in case an unhandled error occurred (for instance, when an 'error' event is emitted by an EventEmitter without an 'error' handler registered).
Thrown in case an invalid or unsupported value was passed for a given argument.
