Link header middleware for express with multiple value and attribute support
npm install set-link
Link header middleware for express with multiple value and attribute support.
The middleware doesn't require any parameters.
Just add it to the express app like this:
``
const setLink = require('set-link')
const app = express()
app.use(setLink)
`
.setLink must be called with the link IRI and the relationship:
`
app.use((req, res) => {
res.setLink('http://example.org/context', 'http://www.w3.org/ns/json-ld#context')
// Link:
})
`
It's also possible to add additional attributes using a key value map:
` `
app.use((req, res) => {
res.setLink('http://example.org/context', 'http://www.w3.org/ns/json-ld#context', {
title: 'example title',
type: 'application/ld+json'
})
// Link:
})
If there is already a link header, the new one will be appended:
`
app.use((req, res, next) => {
res.set('link', '
res.setLink('http://example.org/context', 'http://www.w3.org/ns/json-ld#context')
// Link:
})
