Express middleware for easy JSON-LD link header handling
npm install jsonld-context-link
Express middleware for easy JSON-LD link header handling.
The middleware sends the link header for JSON-LD contexts and hosts the contexts.
The middleware accepts an optional basePath parameter.basePath is used to prefix the context links.
The default value for basePath is /.
To avoid conflicts it's better define a path which isn't used anywhere else in the application.
This would create the middleware, set the basePath to /context/ and attach it to the app:
``
const jsonldContextLink = require('jsonld-context-link')
const app = express()
const contexts = jsonldContextLink({basePath: '/context/'})
app.use(setLink)
`
With .setContext a new context is registered with the given key:
`
contexts.setContext({'@vocab': 'http://schema.org/'}, 'schema')
Now it can be used:
`
app.use((req, res) => {
res.setJsonldContext('schema')
...
})
