Async

findup(dir, fileName, callback) findup(dir, iterator, callback) with iterator(dir, cb) where cb only accept true or false

var findup = require('findup');


findup(__dirname + '/f/e/d/c/b/a', 'config.json', function(err, dir){
  // if(e) e === new Error('not found')
  // dir === '/f/e/d/c'
});

or

findup(__dirname + '/f/e/d/c/b/a', function(dir, cb){
  require('path').exists(dir + '/config.json', cb);
}, function(err, dir){
  // if(e) e === new Error('not found')
  // dir === '/f/e/d/c'
});
EventEmitter

findup(dir, fileName)

var findup = require('findup');
var fup = findup(__dirname + '/f/e/d/c/b/a', 'config.json');

findup(dir, iterator) with iterator(dir, cb) where cb only accept true or false

var findup = require('findup');
var fup = findup(__dirname + '/f/e/d/c/b/a', function(dir, cb){
  require('path').exists(dir + '/config.json', cb);
});

findup return an EventEmitter. 3 events are emitted: found, error, end

found event is emitted each time a file is found.

You can stop the traversing by calling stop manually.

fup.on('found', function(dir){
  // dir === '/f/e/d/c'
  fup.stop();
});

error event is emitted when error happens

fup.on('error', function(e){
  // if(e) e === new Error('not found')
});

end event is emitted at the end of the traversing or after stop() is called.

fup.on('end', function(){
  // happy end
});
Sync

findup(dir, fileName) findup(dir, iteratorSync) with iteratorSync return true or false

var findup = require('findup');

try{
  var dir = findup.sync(__dirname + '/f/e/d/c/b/a', 'config.json'); // dir === '/f/e/d/c'
}catch(e){
  // if(e) e === new Error('not found')
}
