Set specific callbacks for specific responses.
Install gates.js module:
$ npm install gatesjs --saveInclude 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.
