response.step v0.1.0
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(request, response) {
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(request, response) {
response.step(
function(next) {
next(new Error('bad stuff'));
},
function() {
// i am never called
}
);
});
app.error(function(request, response) {
// all errors are forwarded to me
});
