Arise

Run a process "forever". Run a process and spawn it (with arguments) again when it crashes or dies.

Install

cargo install arise

Consider the following node application:

let i = 0

setInterval(_ => {
  i++
  if (i == 10) {
    let x = {}
    console.log(x.y.z)
  }
  console.log(i)
}, 1000)

normally when run (node lol.js) you'll hit a TypeError before getting to 10:

TypeError: Cannot read property 'z' of undefined
    at Timeout._ [as _onTimeout] (/Users/ricky/projects/rust-y/forever/lol.js:7:21)
    at ontimeout (timers.js:466:11)
    at tryOnTimeout (timers.js:304:5)
    at Timer.listOnTimeout (timers.js:267:5)

running it with arise will ensure the process starts up again after it crashes.

example usage

./arise node lol.js
./arise top
