The Future Studio University supports development of this hapi plugin 🚀
Join the Future Studio University and Skyrocket in Node.js
A hapi plugin that gracefully stops the hapi server on SIGINT
and SIGTERM
and your custom signals.
hapi-pulse
works great with PM2 and other Node.js process manager to accomplish zero-downtime deployments!
This serves existing requests before closing the connection and stopping the hapi server process.
It uses hapi’s server.stop()
method to close connections properly.
hapi v19 (or later) and Node.js v12 (or newer)
This plugin requires hapi v19 (or later) and Node.js v12 or newer.
Major Release | hapi.js version | Node.js version |
---|---|---|
v3 | >=17 hapi | >=12 |
v2 | >=17 hapi | >=8 |
Add hapi-pulse
as a dependency to your project:
npm i hapi-pulse
The most straight forward way to register the hapi-pulse
plugin:
await server.register({
plugin: require('hapi-pulse'),
options: {
// any option that is supported by hapi's "server.stop()"
timeout: 15000,
// plugin specific options
logger: console,
signals: ['SIGINT'],
postServerStop: async function () {
// await Database.close()
}
}
})
hapi-pulse
passes the options through to hapi’s server.stop(options)
.
Customize the behavior of server.stop()
, like the timeout
before forcefully stopping the process.
Additionally, you can pass along the following options:
(Object)
, default: console
— in case of an error, hapi-pulse logs the error with logger.error('message', error)
(Array)
, default: ['SIGINT', 'SIGTERM']
— use this signals
option to customize the events on which hapi-pulse will stop the server(Function)
, default: Promise.resolve
— an async function that runs before server.stop()
(Function)
, default: Promise.resolve
— an async function that runs after server.stop()
(Function)
, default: Promise.resolve
— an async function that runs after postServerStop()
and before process.exit
(int)
, default: 5000 (5 seconds)
— the timeout existing connections should be closed until they are forcefully interrupted. This option is passed through to hapi’s server.stop()
Example
await server.register({
plugin: require('hapi-pulse'),
options: {
timeout: 25 * 1000,
logger: console,
signals: ['SIGINT', 'SIGTERM'],
preServerStop: async function () {
// this runs before server.stop()
},
postServerStop: async function () {
// this runs after server.stop()
// e.g., await Database.close()
},
preShutdown: async function () {
// this runs after postServerStop() and before process.exit
}
}
})
// went smooth like chocolate :)
