SyncPromise is an incomplete implementation of Promise API. SyncPromise executes your Promise based code synchronously.
Because sometimes you need to test your Promise based code in a sync scenario.
- Small
- ES6 based
- With tests
- Most of new Promise()
- Most of Promise.prototype.then
- Most of Promise.resolve
- Most of Promise.reject
- Most of Promise.all
Can't handle Promise.prototype.catch for obvious reasons.
- Throws when SyncPromise callback ends without resolving the promise
- Throws when attempting to resolve an already resolved promise
- No Promise.prototype.catch
- No Promise.prototype.race (we accept patches!)
- Some other things probably missing...
