Only one 'graceful application' can be created per Node.js process.

Grace#redirectError(])Ĭreates a 'graceful application' that emits error, start and shutdown events.

Once you feel comfortable with it you probably will never stop using it because it provides the base of a robust web server. Take a look at the examples to fully understand how to use a 'graceful application' -especially with workers and Express. The process can also exit with a custom code. If the process finishes correctly the exit code is 0, otherwise 1. The Express web framework -and all the Express-like frameworks- is fully supported.

Some timers can prevent the exit so all of them are cleared before emitting an exit event, the user may have forgotten to clear them. It also uses domains (global and per request domains), therefore uncaught exceptions doesn't kill the server, absolutely never.įurthermore, if you use workers, the shutdown task takes care of them and transparently manages them in order to always guarantee a graceful shutdown giving to the user a last opportunity to clean up resources. The server can be gracefully killed pressing ctrl-c (Windows and Linux) and sending a SIGINT signal (Linux). When a SIGINT signal is sent to it (on Windows the stdin is read for a ctrl-c key). Provides an event-based mechanism to start and gracefully shutdown a web server. Graceful application with domains, cluster, error handling and Express support

It's working pretty well with the provided examples and is actively tested in edge cases. Because it's pretty hard to write concurrent code, treat with the master and the workers, overriding source code, supporting Windows, Linux and Express and writing a transparent API, this module is in a beta state until it reaches v1.0.0.
