jsonapi-boom

Boom with JSON-api error support.

Build Status Current Version

JsonApiBoom

boom provides a set of utilities for returning HTTP errors.

jsonapi-boom extends Boom utilities with a method signature that accepts any JSON-API attributes, and populates the JSON-API attributes on the error payload.

Each utility returns a Boom error response object (instance of Error) which includes the following properties: (See also the JSON-API Specification for Error Objects)

  • id - a unique identifier for this particular occurrence of the problem.
  • links - a links object containing the following members:
    • about - a link that leads to further details about this particular occurrence of the problem.
  • status - the HTTP status code applicable to this problem, expressed as a string value.
  • code - an application-specific error code, expressed as a string value.
  • title - a short, human-readable summary of the problem that SHOULD NOT change from occurrence to occurrence of the problem, except for purposes of - `localization.
  • detail - a human-readable explanation specific to this occurrence of the problem. Like title, this field’s value can be localized.
  • source - an object containing references to the source of the error, optionally including any of the following members:
    • pointer - a JSON Pointer [RFC6901] to the associated entity in the request document [e.g. "/data" for a primary data object, or "/data/attributes/title" for a specific attribute].
    • parameter - a string indicating which URI query parameter caused the error.
  • meta - a meta object containing non-standard meta-information about the error.
  • isBoom - if true, indicates this is a Boom object instance.
  • isServer - convenience bool indicating status code >= 500.
  • message - the error message.
  • output - the formatted response. Can be directly manipulated after object construction to return a custom error response. Allowed root keys:
    • statusCode - the HTTP status code (typically 4xx or 5xx).
    • headers - an object containing any HTTP headers where each key is a header name and value is the header content.
    • payload - the formatted object used as the response payload (stringified). Can be directly manipulated but any changes will be lost if reformat() is called. Any content allowed and by default includes the following content:
      • statusCode - the HTTP status code, derived from error.output.statusCode.
      • error - the HTTP status message (e.g. 'Bad Request', 'Internal Server Error') derived from statusCode.
      • message - the error message derived from error.message.
  • inherited Error properties.

The JsonApiBoom object also supports the following method:

  • reformat() - rebuilds error.output using the other object properties.

Options

Each utility can be called with an object containing any of the JSON-API attributes.

var error = JsonApiBoom.badRequest({
  id: 'abc-123',
  code: 'y-5678',
  source: {
    parameter: 'included'
  },
  meta: {
    something: 'else'
  },
  err: new Error('Opps!')
});

Generates the following response payload:

{
    "id": "abc-123",
    "links": {
        "about": "http://api.example.com/docs/errors/y-5678"
    },
    "status": 400,
    "statusCode": 400,
    "code": "y-5678",
    "title": "Bad Request",
    "error": "Bad Request",
    "detail": "Opps!",
    "message": "Opps!",
    "source": {
        "pointer": "",
        "parameter": "included"
    },
    "meta": {
        "something": "else"
    },
}

Methods

Each utility can also be called with the original boom signature, meaning you can switch boom for this package for in your existing API and you will obtain mimially JSON-API compliant error objects.

wrap(error, [statusCode], [message])

Decorates an error with the boom properties where:

  • error - the error object to wrap. If error is already a boom object, returns back the same object.
  • statusCode - optional HTTP status code. Defaults to 500.
  • message - optional message string. If the error already has a message, it adds the message as a prefix. Defaults to no message.
var error = new Error('Unexpected input');
JsonApiBoom.wrap(error, 400);

create(statusCode, [message], [data])

Generates an Error object with the boom decorations where:

  • statusCode - an HTTP error code number. Must be greater or equal 400.
  • message - optional message string.
  • data - additional error data set to error.data property.
var error = JsonApiBoom.create(400, 'Bad request', { timestamp: Date.now() });

HTTP 4xx Errors

JsonApiBoom.badRequest([message], [data])

Returns a 400 Bad Request error where:

  • message - optional message.
  • data - optional additional error data.
JsonApiBoom.badRequest('invalid query');

Generates the following response payload:

{
    "statusCode": 400,
    "error": "Bad Request",
    "message": "invalid query"
}

JsonApiBoom.unauthorized([message], [scheme], [attributes])

Returns a 401 Unauthorized error where:

  • message - optional message.
  • scheme can be one of the following:
    • an authentication scheme name
    • an array of string values. These values will be separated by ', ' and set to the 'WWW-Authenticate' header.
  • attributes - an object of values to use while setting the 'WWW-Authenticate' header. This value is only used when scheme is a string, otherwise it is ignored. Every key/value pair will be included in the 'WWW-Authenticate' in the format of 'key="value"' as well as in the response payload under the attributes key. null and undefined will be replaced with an empty string. If attributes is set, message will be used as the 'error' segment of the 'WWW-Authenticate' header. If message is unset, the 'error' segment of the header will not be present and isMissing will be true on the error object.

If either scheme or attributes are set, the resultant Boom object will have the 'WWW-Authenticate' header set for the response.
