json-format-tool

Introduction

Okay, this is a tiny cli-tool for format JSON.

Usage

First install

npm i -g json-format-tool

And if we have a not pretty JSON file like this one.

  {
  "foo": "foo",
   "bar": { "x": "我", "z": 234, "y": 345 },
    "baz": [3, 2, { "b": 234, "a": 123 }]
 }

We can format it.

json-format-tool demo.json

It will output

{
  "bar": {
    "x": "我",
    "y": 345,
    "z": 234
  },
  "baz": [
    3,
    2,
    {
      "a": 123,
      "b": 234
    }
  ],
  "foo": "foo"
}

It's much pretty now.

And if you want format some mutable JSON such as HTTP request, you can use the pipe operator.

curl -X GET http://127.0.0.1:3000/my-api | json-format-tool

Other options you can check inside the cli tool.
