async alternatives and similar packages
Based on the "Goroutines" category
-
semaphore
Semaphore pattern implementation with timeout of lock/unlock operations based on channel and context. -
Hunch
Hunch provides functions like: All, First, Retry, Waterfall etc., that makes asynchronous flow control more intuitive. -
go-tools/multithreading
Manage a pool of goroutines using this lightweight library with a simple API. -
conexec
A concurrent toolkit to help execute funcs concurrently in an efficient and safe way.It supports specifying the overall timeout to avoid blocking and uses goroutine pool to improve efficiency. -
queue
Gives you a sync.WaitGroup like queue group accessibility. Helps you to throttle and limit goroutines, wait for the end of the all goroutines and much more. -
oversight
Oversight is a complete implementation of the Erlang supervision trees.
Do you think we are missing an alternative of async or a related project?

Async
Provides a safe way to execute fns's functions asynchronously, recovering them in case of panic. It also provides an error stack aiming to facilitate fail causes discovery.
Usage
func InsertAsynchronously(ctx context.Context) error {
transaction := db.Transaction().Begin()
err := async.Run(ctx,
func(_ context.Context) error {
_, err := transaction.Exec(`
INSERT INTO foo (bar)
VALUES ('Hello')
`)
return err
},
func(_ context.Context) error {
_, err := transaction.Exec(`
INSERT INTO foo (bar)
VALUES ('world')
`)
return err
},
func(_ context.Context) error {
_, err := transaction.Exec(`
INSERT INTO foo (bar)
VALUES ('asynchronously!')
`)
return err
},
)
if err != nil {
e := transaction.Rollback()
log.IfError(e)
return err
}
return transaction.Commit()
}
