perish


tiny module to log and exit on uncaughtException and unhandledRejection events

install

npm install --save(-dev) perish

usage

require('perish')

that's all. in any nodejs file.

what

listen for uncaughtException & unhandledRejection in node processes. when those events occur, log the message and the stack, then exit with exit code 1.

why

because apps should die hard if their errors aren't handled. some apps require graceful exit onerror. sometimes this is feasible, sometimes this is not. this package is simple and just exits.

example

``js
// unhandled.js
Promise.reject(new Error('bananas'))
`

run node unhandled.js and ... nothing.

`js
// handled.js
require('perish')
Promise.reject(new Error('bananas'))
`

run node handled.js and:

`js
Error: bananas
at Object. (/some/path/handled.js:2:16)
at Module._compile (module.js:541:32)
at Object.Module._extensions..js (module.js:550:10)
at Module.load (module.js:458:32)
at tryModuleLoad (module.js:417:12)
at Function.Module._load (module.js:409:3)
at Function.Module.runMain (module.js:575:10)
at startup (node.js:160:18)
at node.js:456:3

`

nothin' too fancy!

api

`js
const perish = require('perish')
perish.printStacktrace // default true. set to false to console.error error message only
perish.fail // @private. this is the error handler
