hcl-to-json

Build Status NPM version

HCL to JSON converter for JS applications.

HCL (HashiCorp Configuration Language) is a configuration language built by HashiCorp. The goal of HCL is to build a structured configuration language that is both human and machine friendly for use with command-line tools, but specifically targeted towards DevOps tools, servers, etc.

HCL is also fully JSON compatible. That is, JSON can be used as completely valid input to a system expecting HCL. This helps makes systems interoperable with other systems.

Getting started

You can install with npm i hcl-to-json -g then simply require and pass HCL content to get JSON output. If you have a bad HCL content it's suggested to call in try .. catch block


hcltojson = require 'hcltojson'

hcltojson """

foo "bar" {
  baz = 123
  tex = ["one", "two"]
  mon "test" {
    lar = "bar"
  }
}

"""

will return following JSON object:

{
  "foo": {
    "bar": {
      "baz": 123,
      "tex": [
        "one",
        "two"
      ],
      "mon": {
        "test": {
          "lar": "bar"
        }
      }
    }
  }
}

or you can use the hcltojson cli for any hcl formatted file or standart input;

$ npm install hcl-to-json -g
$ echo "foo=3" | hcltojson
{
    "foo": 3
}

$ echo "foo bar { baz = 123 }" > test.tf
$ hcltojson test.tf
{
    "foo": {
        "bar": {
            "baz": 123
        }
    }
}

In browser you may include the dist/bundle.js which will export hcltojson function into window. You can also try it in your browser from https://runkit.com/npm/hcl-to-json
