nconf-wacthfile

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

Usage

`` bash
npm i nconf-wacthfile
`

In your node file:
` js
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.
