sails-hook-restful-promise

Sails JS hook to communicate with RESTful APIs (HTTP/HTTPS) and returns a Promise.

All this without even a single external dependency

Installation

npm install --save sails-hook-restful-promise

Usage

sails.hooks.RESTful
            .send(options)
            .then(function (response) {
                console.log(response);
            })
            .catch(function (err) {
                console.error(err);
            });

Where options is an Object, which can have the following keys (all optional):

• protocol: (String) http or https (Default is http)
• hostname: (String) The API endpoint (Default is localhost)
• port: (Number) The API port (Default is 80 for http and 443 for https)
• path: (String) The API Path (Default is empty path)
• body: (String) The API request body (if any) (Default is empty body)
• qs: (Object) The Query String in key value notation. e.g.: {q:'foo',s='bar'} means ?q=foo&s=bar
• method: (String) The HTTP Method (Defaults to GET)
• headers: (Object) Any custom HTTP Headers to send in key value notation. e.g.: {'Content-Type': 'application/json'}
• timeout: (Number) The HTTP API call timeout in milliseconds (Defaults to 0, which means no timeout)
• returnHeaders: (Boolean) Weather to return HTTP Headers as received from the API Response. Default is false

Response format

If the API call is successful (no matter what the HTTP Status or the response is), the promise resolves with the response object in the following format:

{
    status: 200,
    body: 'The exact body returned by the API Response in String format'
    headers: {
        //Key: 'Value' pairs of all headers retirned by the server.
    }
}

Note: headers is only available when returnHeaders is set to true in request.options.

Defining Defaults

Following options can be defined as defaults from the sails.config. Just add a config/restful.js file in your sails installation with following content:

module.exports.RESTful = {
    protocol: 'http', // Only 'http' or 'https' allowed here
    hostname: 'localhost',
    portHTTP: 80,
    portHTTPS: 443,
    headers: {}, //Any custom HTTP Headers to send in key value notation. e.g.: {'Content-Type': 'application/json'}
    timeout: 0, //If positive, in milliseconds. 0 means don't set timeout
    returnHeaders: false //Weather to return HTTP Headers as received from the API Response
}
