commands-queue

execute command line in a synchronized fashion

• concurrently
• in a concurrent sized queue
• serially

npm install --save commands-queue

The following example execute all given commands in a concurrent queue of size 2:

const CommandQueue = require('commands-queue')
const queue = new CommandQueue({concurrency: 2})
queue.exec('cd project1 && npm install && npm run build && npm test')
queue.exec('cd project2 && npm install && npm run build && npm test')
queue.exec('cd project3 && npm install && npm run build && npm test').then(result=>console.log('echo "almost there", exit code: '+result.code))
queue.exec('cd project4 && npm install && npm run build && npm test')

Or similar to above but this time registering all the commands first and then start executing them programmatically:

(TODO)

const CommandQueue = require('commands-queue')
const queue = new CommandQueue({concurrency: 2, autoStart: false})
queue.exec('cd project1 && npm install && npm run build && npm test')
queue.exec('cd project2 && npm install && npm run build && npm test')
queue.exec('cd project3 && npm install && npm run build && npm test').then(console.log('echo "almost there"'))
queue.exec('cd project4 && npm install && npm run build && npm test')
queue.onIdle().then(()=>console.log('ALL WORK DONE'))
const results = await queue.start()
