How do you run the Express 4 app with Forever? (or is there a new package?)
I am running my Express 3 apps with Forever installed locally with the package manager. I use the command:
forever -a start app.js
What is forever? Forever is an npm module that ensures a Node. js script continuously runs in the background on the server. It's a helpful CLI tool for the production environment because it helps manage the Node applications and their processes.
Express is currently, and for many years, the de-facto library in the Node. js ecosystem. When you are looking for any tutorial to learn Node, Express is presented and taught to people.
forever and PM2 can be primarily classified as "Node. js Process Manager" tools. forever and PM2 are both open source tools. It seems that PM2 with 30K GitHub stars and 2K forks on GitHub has more adoption than forever with 12.5K GitHub stars and 906 GitHub forks.
js application locally after closing the terminal or Application, to run the nodeJS application permanently. We use NPM modules such as forever or PM2 to ensure that a given script runs continuously. NPM is a Default Package manager for Node.
Try this:
forever start ./bin/www
Let's take a look to package.json
:
"scripts": {
"start": "node ./bin/www"
},
I guess when we call npm start
, ./bin/www
will be executed at some point.
Then look at the content of./bin/www
:
var server = app.listen(app.get('port'), function() {
debug('Express server listening on port ' + server.address().port);
});
so we are ready to listen for connections.
forever start --minUptime 1000 --spinSleepTime 1000 ./bin/www
