ganomede-base-client

Simple wrapper around restify.JsonClient to start with when writing own API Clients. Changes:

• single request()-like method (#apiCall({method, path, body, headers, qs}, callback)), meaning:
  • base urls;
  • per request headers;
  • easier query string;
• supports path prefixes (useful if you want to have something like /api/v1 in front of all requests);
• if body or qs contain req_id param, sets x-request-id header to value of it.

Basic Usage

Import BaseClient and define higher-level APIs.

const BaseClient = require('ganomede-base-client');

class MyApi extends BaseClient {
  constructor ({hostname = 'my-api.example.org', version = 1, apiKey}) {
    super(
      `https://${hostname}/version-${version}`,  // base url
      {headers: {'X-API-Key': apiKey}}           // more options
    );
  }

  ping (callback) {
    // Will issue HTTP GET to
    // https://my-api.example.org/version-1/ping?check-auth=1
    //
    // Callback will contain JSON response (if any, otherwise empty object),
    // see restify docs for more details at:
    // https://github.com/restify/clients
    //
    // `call` is what restify methods return (like #get(), #post(), etc.).
    const call = this.apiCall(
      {method: 'get', path: '/ping', qs: {'check-auth': 1}},
      callback
    );
  }
}

Custom defaults

Some defaults are changed from those of restify:

• up to 3 attempts on establishing TCP connections with exponential timeout between 1 and 5 seconds;
• default headers:
  • accept of application/json;
  • accept-encoding of gzip,deflate.
