wpcom-xhr-request

REST-API and WP-API requests via XMLHttpRequest (and CORS)

CircleCI

You likely want to use the high-level APIs in wpcom.js instead of using this module directly.

Works in both the browser and Node.js via superagent.

Installation

Install wpcom-xhr-request using npm:

$ npm install wpcom-xhr-request

Example

<html>
  <body>
    <script src="wpcom-xhr-request.js"></script>
    <script>
      WPCOM.xhr('/me', function(err, data) {
        if (err) throw err;

        var div = document.createElement('div');
        div.innerHTML = 'Your WordPress.com "username" is: <b>@' + data.username + '<\/b>';
        document.body.appendChild(div);
      });
    </script>
  </body>
</html>

API

wpcomXhrRequest( [params], fn )

Params: optional parameters

  • method: GET as default.
  • apiNamespace: WP-API namepsace.
  • apiVersion: REST-API app version - 1 as default.
  • proxyOrigin: https://public-api.wordpress.com as default.
  • authToken: token authentication.

fn: request callback function

This function has three parameters:

  • error: defined if the request fails
  • body: the object body of the response
  • headers: the headers of the response
import handler from `wpcom-xhr-request`;

// get .com blog data usign `REST-API`
handler( '/sites/en.blog.wordpress.com', ( error, body, headers ) => {
  if ( error ) {
    return console.error( 'Request failed: ', error );
  }
  
  console.log( 'WordPress blog: ', body );
} );

// get .com blog data using `WP-API`
handler( {
  path: '/sites/en.blog.wordpress.com',
  apiNamespace: 'wp/v2'
}, ( error, body, headers ) => {
  if ( error ) {
    return console.error( 'Request failed: ', error );
  }
  
  console.log( 'WordPress blog: ', body );
} );

// get .org blog data (`WP-API`)
handler( {
  proxyOrigin: 'http://myblog.org/wp-json',
  path: '/',
  apiNamespace: 'wp/v2'
}, ( error, body, headers ) => {
  if ( error ) {
    return console.error( 'Request failed: ', error );
  }
  
  console.log( 'WordPress blog: ', body );
} );

Authentication

For API requests that require authentication to WordPress.com, you must pass in an OAuth token as the authToken parameter in the params object for the API call.

You can get an OAuth token server-side through node-wpcom-oauth, or any other OAuth2 interaction mechanism.
