httpLink is a terminating link that sends a tRPC operation to a tRPC procedure over HTTP.

httpLink supports both POST and GET requests.

Usage

You can import and add the httpLink to the links array as such:

client/index.ts

import { createTRPCClient, httpLink } from '@trpc/client';

import type { AppRouter } from './server';

const client = createTRPCClient<AppRouter>({

links: [

`httpLink({`

  `url: 'http://localhost:3000',`

  `// transformer,`

`}),`

],

});

The httpLink function takes an options object that has the HTTPLinkOptions shape.

export interface HTTPLinkOptions {

url: string | URL;

/**

* Add ponyfill for fetch

*/

fetch?: typeof fetch;

/**

* Data transformer

* @see https://trpc.io/docs/server/data-transformers

**/

transformer?: DataTransformerOptions;

/**

* Headers to be set on outgoing requests or a callback that of said headers

* @see https://trpc.io/docs/client/headers

*/

headers?:

`| HTTPHeaders`

`| ((opts: { op: Operation }) => HTTPHeaders | Promise<HTTPHeaders>);`

/**

* Send all requests as POSTS requests regardless of the procedure type

* The server must separately allow overriding the method. See:

* @see https://trpc.io/docs/rpc

*/

methodOverride?: 'POST';

}
