我可以从节点 cli 应用程序切换到 bash 吗？

Question

I'm working on a fairly simple node cli application for my agency that allows you to add clients and any of their sites to a db (lowdb) and then basically run the script with the client name to hand you off to an ssh session on their server. I've tried the exec module, but it's just showing the password or key password prompt from ssh and not allowing me to actually continue with the session.

I'm wondering if there is a clean way to basically execute that initial ssh command but then just be running that on bash and not through the node app?

For example: If I use the following code...

exec('ssh [options we always need] client@clientserver.com');

I get the following...

$ client's password: []

But it's just printing the stdout, not allowing me to continue with the session. I just want the node cli to effectively end after starting the bash command running, allowing the user to login and continue as usual.

Why not just use a dedicated library instead of the command-line interface? Simply, implement the API and get the console input for the 'password', and then just pipe all command-line input to the SSH stream.

With node-ssh-forward , you simply establish a connection with the server using the input from the CLI and use the sshConnection.executeCommand('') command with the input from the user. This library also supports callbacks so you can just console.log the results from the callback.
