trailpack-autoreload's Introduction

trailpack-autoreload

NPM version Build status Dependency Status Code Climate

This Trailpack will automatically reload your Trails application on code changes. It listens for changes in api/ and config/.

Install

$ npm install --save trailpack-autoreload

Configure

// config/main.js
module.exports = {
  packs: [
    // ... other trailpacks
    require('trailpack-autoreload')
  ]
}

This trailpack offers significant performance advantages over other solutions such as nodemon, which restarts the entire node process. This trailpack detects the file(s) in which the change occured, evicts those modules from the require cache, and reloads the Trails application (via app.start()). Moreover, the application will continue running in its current state if a syntax error is written into a watched file; Trails will inform you of the error, and carry on.

The synchronous node require statement incurs non-negligible boot-time overhead. We avoid these costs by evicting only the affected module(s).

trailpack-autoreload's Issues

"Cannot assign to read only property ..." errors on reload in trailpacks

Following errors occur on reload in my current trails set up:

error: 
 TypeError: Cannot assign to read only property 'server' of object '#<Object>'
    at HapiTrailpack.configure (node_modules/trailpack-hapi/index.js:38:22)
    at app.after.then (node_modules/trails/lib/trailpack.js:63:26)

Autoreload not work

Not work for me
node 4.4.4, express 4

When I change text I have message in console, but web page does not change. Nodemon work fine
index(req, res) { res.send('Text') }
trails > info: App reloaded with changes in api/controllers/TestController.js

Changes not applied when reloading

So get this message in the console:

trails > info: App reloaded with changes in api/controllers/TransactionsController.js

But the changes are not applied, I still get the same response from the server, even I changed it. I tried manually changing the package in node_modules and setting usePolling: true but still doesn't work. Any ideas?
