Set specific callbacks for specific responses.

Install gates.js module:

$ npm install gatesjs --save

Include module in your project:

const gates = require("gatesjs");

Set up your gates in main request callback. Using set method pass response's code value:

new gates().set( response.statusCode )

Each gate function needs two parameters: array with condition rules and callback function. The first array's element is an expected status code (required, in example below 200), the second one is an optional expression (e.g. foo === true):

request("http://example.com/foo.json", (error, response, body) => {

  body = JSON.parse( body ); // => { foo: true }

  new gates().set( response.code )

       .gate([ 200 , body.foo === true ], () => console.log( "Hello 200 callback and true foo!" ) );

});

If there's a possibility the condition could not be met, set default callback using default method:

 .default( () => console.log( "Hello default callback!" ) );

For any kind of response codes or any expression use asterisk * argument:

 .gate([ "*", data.foo === false ], () => console.log( "Hello callback for whatever status and falsy foo!" ) )
 .gate([ 404, "*" ], () =>  console.log( "Hello callback for 404 status and whatever!" ) );

When you clone the repository check for more examples by launching $ node index.js after $ npm install.
