response.step

flow control on for root

response.step

response.step is a small plugin for root that adds a step function to the response

npm install response.step

response.step is useful is when nested async code needs to be flattened out a bit

var root = require('root');
 
var app = root();
 
app.use(require('response.step'));
 
app.get(function(requestresponse) {
response.step(
function(next) {
setTimeout(next, 300);
},
function(next) {
setTimeout(next, 500);
},
function() {
response.send('waiting approx 800ms!\n');
}
);
});
 
app.listen(8080);

response.step takes care of all our error handling for us.

app.get(function(requestresponse) {
response.step(
function(next) {
next(new Error('bad stuff'));
},
function() {
// i am never called 
}
);
});
 
app.error(function(requestresponse) {
// all errors are forwarded to me 
});
