node-routine


node-routine is a library to implement Goroutine-Like API with worker_threads.

Compared to using the worker threads low level API directly, node-routine can make your codes more elegantly, like:

``
await go(() => (Math.random()))
`

npm install -S node-routine
`

Quick Example

`javascript
const { go, init, shutdown } = require('node-routine')

// init a worker threads pool
init({
maxWorkerThreads: 2,
})

async function calc() {
// every routine will be executed in worker threads pool
const count = 10000
const num = await go(() => {
let total = 0
for (let i = 0; i < count; ++i) {
total += i
}
return total
}, { count })

return num
}

calc().then((total) => {
console.log('Got', total)
shutdown()
})
`
