This is a HCL version 2 parser for JavaScript, there are several other JS parsers for HCL but none that support the newer HCL v2 syntax
It wraps the very helpful tmccombs/hcl2json and calls the convert package in order to parse HCL input strings to JSON strings. The Go code in parser.go is converted to JS using GopherJS
TypeScript definitions are included
The module exports the following functions:
function parseToString(input: string): string
function parseToObject(input: string): anyInstall as normal with NPM
npm install hcl2-parserImporting into your project
// Good old fashioned Node.js CommonJS require
const hcl = require("hcl2-parser")
// Import with ES6 or TypeScript
import * as hcl = from "hcl2-parser"Simple example of usage
const hcl = require("hcl2-parser")
const hclString = `
# Create a resource group
variable "azureRegion" {
type = string
default = "uksouth"
}
resource "azurerm_resource_group" "example" {
name = "example-resources"
location = var.azureRegion
}
`
// Parse into a JSON string
stringResult = hcl.parseToString(hclString)
console.log(stringResult)
// Parse into an object, the actual result is in array index 0 for reasons I don't understand
objectResult = hcl.parseToObject(hclString)
console.log(objectResult[0].resource.azurerm_resource_group)
