node-json-watch
auto reload a json file when it's changed without restart your project
installation
npm install json-watch
usage
var jsonWatcher = require('json-watch');
jsonWatcher.watch('/absolute/path/to/the/file.json');
// then you can use `jsonWatcher.get()` to access your data
console.log(jsonWatcher.get())
// if `file.json` is changed, the value of `jsonWatcher.get()` will auto reload, no need to restart your project
Important: use jsonWatcher.get(), not var json = jsonWatcher.get(); console.log(json);. otherwise the json will not change when the file changed
