nodejs child processes

node-spawn.md

from: prisma/prisma#2917

The reason Prisma is cleaning up its child processes, is we'll end up with a dangling child process. So unfortunately Node.js does not make sure, that the child process is killed properly. That's why Prisma Client is cleaning this up, for now, to not introduce a foot gun for Prisma users.

index.js

const { spawn } = require('child_process')
const path = require('path')
const child = spawn('node', [path.join(__dirname, 'run.js')], {
  stdio: 'inherit',
})
setTimeout(() => {
  process.exit()
}, 100)

run.js

console.log('hao', process.pid)
setTimeout(() => {
  console.log('hi')
}, 100000000)
