How to make js-beautify --editorconfig work well when using bash pipeline.

[hujianxin]

Description

In my project, there is a .editorconfig file and a .jsbeautifyrc file.

The content of .editorconfig is:

root = true

[*]
indent_style = space 
indent_size = 2

The content of .jsbeautifyrc is:

{
  "editorconfig": true
}

If I use command js-beautify app.js, the output code will be indented with 2 space.
If I use command cat app.js | js-beautify, the output code will not change to 2 space. Same that when using shell pipeline, js-beautify won't read .editorconfig file.

Input

The code looked like this before beautification:

if (true) {
    something;
}

Expected Output

The code should have looked like this after beautification:

if (true) {
  something;
}

Actual Output

The code actually looked like this after beautification:

if (true) {
    something;
}

Steps to Reproduce

Environment

OS:
ubuntu 16.04 64bit
