nodejs wait for exec in function

Question

const exec = require(\'child_process\').exec;

funct         


        

Answer 1

exec will deal with it in an async fashion, so you should receive a callback or return a promise.

One thing you could do in order to make it sync is to use execSync instead:

https://nodejs.org/api/child_process.html#child_process_child_process_execsync_command_options

The child_process.execSync() method is generally identical to child_process.exec() with the exception that the method will not return until the child process has fully closed. When a timeout has been encountered and killSignal is sent, the method won't return until the process has completely exited. Note that if the child process intercepts and handles the SIGTERM signal and doesn't exit, the parent process will wait until the child process has exited.
