Wildcard Intercept

Library for Wildcard API to intercept calls.

// ./example/endpoints.js

const {endpoints} = require('@wildcard-api/server');
const intercept = require('@brillout/wildcard-intercept'); // npm install @brillout/wildcard-intercept

endpoints.hello = intercept(function(name) {
  return 'Hi '+name+'!';
}, myListener);

endpoints.mirror = intercept(function(msg) {
  return msg.split('').reverse().join('');
}, myListener);

function myListener({endpointName, endpointArgs, endpointResult, endpointError, context}) {
  console.log({endpointName, endpointArgs, endpointResult, endpointError, context});
}

// ./example/client.js

const {endpoints} = require('@wildcard-api/client');
const wildcard = require('@wildcard-api/client');

wildcard.serverUrl = 'http://localhost:3000';

(async function() {
  let greeting = await endpoints.hello('Johnson');
  console.log(greeting);
  greeting = await endpoints.mirror(greeting);
  console.log(greeting);
})();

Client console.log result:

Hi Johnson!
!nosnhoJ iH

Server console.log result:

{
  endpointName: 'hello',
  endpointArgs: [ 'Johnson' ],
  endpointResult: 'Hi Johnson!',
  endpointError: undefined,
  context: {

      connection: 'close',
      accept: '*/*',
      'content-length': '0',
      host: 'localhost:3000'
    }
  }
}
