nconf-wacthfile

Add a prototype method watchFile to nconf.Prodiver for auto-reloading any change in your config file.

Usage

npm i nconf-wacthfile

In your node file:

var nconf = require('./lib/nconf-watchfile');

nconf.env({
  whitelist: ['host']
}).watchFile({
  file: './test/test-config.json',
  onChange: function(/* store, path*/) {
    console.log(nconf.get());
  },
  onError: function(err, path) {
    console.error(err, path);
  }
}).defaults({
  host: 'DEFAULT_HOST'
})
console.log(nconf.get())

Any change in './test/test-config.json' in occured after watchFile calling will be merged to nconf store.

Options

1. file: refer to https://github.com/indexzero/nconf#file. You can use any options that nconf.file accepted(secure, format).
2. onChange(store, path): A callback will be fired while config file changed. store is the parsed value.
3. onError(err, path): A callback will be fired while parsing failed.
4. watch: Chokidar optinons for file change monitoring. * I've set watch.ignoreInitial = true to ignore first change event.

Test

TBD.
