var fs = require('fs');

AwaitFlow.run(function(await) {

  // read file async

  var content = await(function(next) {

    fs.readFile('./package.json', 'utf8', next);

  });

  // wait 1000ms

  await(function(next) {

    setTimeout(next, 1000);

  });

  // output file content

  console.log(content);

});

```

```javascript

var AwaitFlow = require('await-flow');

var fs = require('fs');

AwaitFlow.run(function(await) {

  var content = await(function(next) {

    // not exists file

    fs.readFile('/foo/bar/baz', 'utf8', next);

  });

  console.log(content); // This line will not be executed

}, function(err) {

  console.log(err);

  //=> { [Error: ENOENT, open '/foo/bar/baz'] errno: 34, code: 'ENOENT', path: '/foo/bar/baz' }
