Running rails console command from nodejs

Question

Is it possible to spawn rails console from nodejs and then execute the script in rails console ?

const { spawn } = require('child_process');
const child_process = spawn('rails c');
child_process.stdout.on('data', function (data) {
 console.log('stdout', data.toString());
});
child_process.stderr.on('data', function (data) {
 console.log('stderr', data);
});
child_process.on('close', function (code) {
 console.log('close', code);
});

Upon opening the console, i wanted to execute this script in the rails console

user_id = 1624522827
Sharding.get_shard(user_id) do
 account = UserList::User.find(user_id).make_user
end

How to achieve this in nodejs. My intention is to create a cli that runs script inside rails console.

Answer 1

I think what you want is rails runner instead of console. Either pass it a line of ruby code or a filename. It will run in the rails environment, not just the ruby irb environment.

Answer 2

The ruby console is for humans. I wouldn't try and pipe input into it.

A better idea is to use a rake task and then call that with

bundle exec rake task:subtask

guide for rake tasks

All your code should go in the rake task and then you can call it from nodejs using just the filepath.
