express-rdf-problem-details

express-rdf-problem-details

This package wraps express-http-problem-details so that RDF/Linked Data express applications will return Problem documents (RFC7807) as valid JSON-LD.

This is done simply by adding a Link header pointing to a JSON-LD @context. By default, it's the context provided by Hydra Community Group

Usage

import express from 'express'
import * as error from 'express-rdf-problem-details'
import { NotFoundMapper } from './error-mappers'

const app = express()

// All params optional
express.use(error.handler({
  // change the @context URL
  context: 'http://example.com/error.jsonld',
  // additional mappers to customize error documents
  mappers: [new NotFoundMapper()] 
}))

Implementing mappers is explained in PDMLab/express-http-problem-details
