Nupper

NodeJS Application Updater

I couldn't find a module that did this so I made one.

npm install --save nupper

Features

• Automatically update your NodeJS application using a remote resource
• Automatic from start to right before the restart. (Wanted a lightweight solution, so it's up to you to restart)
• Automatic dependecy install (I think)
• Some events for your coding pleasure

const Nupper = require('nupper');

var settings = {
    repoLocation: 'ImBaedin/autoupdatetest',
    branch: 'master'
};

var nuppyBoi = new Nupper(settings);

nuppyBoi.checkUpdate();

nupBoi.on(nupBoi.events.OUT_OF_DATE, ()=>{
    nuppyBoi.downloadUpdate();
});

nupBoi.on(nupBoi.events.DOWNLOAD_COMPLETE, ()=>{
    nuppyBoi.updateFromFile();
});

nupBoi.on(nupBoi.events.INSTALL_COMPLETE, ()=>{
    console.log('Probably a good idea to restart.');
});
