I'm trying to use continuation-local-storage module to have "currentUser"
across my entire application.
When calling async waterfall the context gets lost.
app.get('/testing/cls',
function(req, res, next) {
ns.run(function() {
ns.set('currentUser', req.user._id)
return next()
})
},
function(req, res) {
function fn1(cb) {
console.log('async fn1', ns.get('currentUser'))
return cb()
}
function fn2(cb) {
console.log('async fn2', ns.get('currentUser'))
cb()
}
function fn3(cb) {
console.log('async fn3', ns.get('currentUser'))
cb()
}
async.waterfall([
fn1,
fn2,
fn3
], function() {
console.log('async waterfall done', ns.get('currentUser'))
res.send({user: ns.get('currentUser')})
})
}
)
The console prints are
27/6/2017-11:49:39 - info: (13405) - async fn1 58a1adaslkdjh32e
27/6/2017-11:49:39 - info: (13405) - async fn2
27/6/2017-11:49:39 - info: (13405) - async fn3
27/6/2017-11:49:39 - info: (13405) - async waterfall done
Fixing this problem is by wrapping ns.bind(fn2) but this means that need to
change entire application code for wherever I have async.
What am I doing wrong?
Any help is appreciated :)
