Listens for changes in Vantage.js extension files, and reloads the extensions without interrupting your app's lifecycle.
Useful when developing new Vantage commands.
npm install vantage-watch
npm install vantageconst Vantage = require('vantage');
const watch = require('vantage-watch');
const commands = require('./lib/vantage-commands');
let vantage = new Vantage();
vantage
.listen(4000)
.use(commands)
.use(watch, {
files: ['./lib/vantage-commands.js']
})
.show();Now, whenever ./lib/vantage-commands.js is changed, Vantage will import and update its existing commands and / or register new commands.
If the watched file is not a valid Vantage extension, vantage-watch will gracefully catch the error and not attempt to load the module until it has been changed again, at which point it will retry. Examples of invalid imports include:
- Its
module.exportsdoes not return a function - It has syntax errors
- It is not a valid file
