Curveball Links middleware
This Curveball middleware helps you parse and generate HTTP Weblinks.
Any links passed in a request via the Link header will now be exposed in
ctx.request. Similarly, if a link was set in ctx.response.links, it will
automatically be encoded as a Link header in the HTTP response.
Lastly, if the request body was a HAL object, and it has a _links
property, these links will also be added to ctx.response.links.
Installation
npm i @curveball/links
Usage
import { Application, Context } from '@curveball/core';
import links from '@curveball/links';
import bodyParser from '@curveball/bodyparser';
const app = new Application();
// If you would like to parse HAL links, the bodyParser must be loaded first.
app.use(bodyParser());
app.use(links());
app.use( (ctx: Context) => {
// Read a Link from a HAL body or Link header
console.log(ctx.request.links.get('author'));
// Write a Link header
ctx.response.links.set({ rel: 'alternate' , type: 'text/csv', href: '/export.csv'});
});
