var domain = require('domain'); | |
var d = domain.create(); | |
// Example 1: callback style | |
d.run(() => { | |
console.log('Initial domain is', process.domain); | |
setTimeout(() => { | |
console.log('Final domain is', process.domain); // good | |
}, 1000); | |
}); | |
// Example 2: promises | |
d.run(() => { | |
console.log('Initial domain is', process.domain); | |
Promise.resolve('foo').then(() => { | |
console.log('Final domain is', process.domain); // undefined! | |
}); | |
}); | |
// Example 3: Bluebird promises (tested with 3.5.0) | |
var Promise = require('bluebird'); | |
d.run(() => { | |
console.log('Initial domain is', process.domain); | |
Promise.resolve('foo').then(() => { | |
console.log('Final domain is', process.domain); // good | |
}); | |
}); | |
// Solution: global.Promise = require('bluebird'); |
