Convert Json to .Env File

Supports for CommonJS (CJS) and ECMAScript (ESM).

⭐ Features

1. Convert json to .env file.
2. Create env.json file optionally.
3. Overwrite existing .env file optionally.
4. Instantes log messages to show the progress of the process, optionally.
5. Accept up to 5 levels deep of Objects [nested objects]

• INPUT Json File Example:

  {
      // First Level
      "port": 6666,
      "array": ["a", "b", "c"],
      "dbUri": {
          // Second Level
          "host": "127.0.0.1",
          "port": 666,
          "db": {
              // Third Level
              "name": "DB_X1",
              "array_2": ["1", "2", "3"],
              "user": {
                  // Fourth Level
                  "name": "ABC",
                  "password": null,
                  "role": {
                      // Fifth Level
                      "name": "ADMIN",
                      "permissions": ["READ", "WRITE", "DELETE"]
                  },
                  "number": 789
              },
              "password": 12345678
          }
      },
      "logLevel": true,
  }

Installation

npm install --save-dev dynamic.envs

🚀 Getting started

Setup

ESM example:

import JsonToEnv from "dynamic.envs";

const set = new JsonToEnv({
    readFileFrom: path.join(__dirname, "..","FILE_NAME.json"),
    saveFileTo: path.join(__dirname, "..", ".env")
  }, {
    overWrite_Original_Env: true, // if you dont want to overwrite your original .env file, set this to true
    createJsonFile: true, // If you want to create a new json file, set this to true
    createEnvFile: true, // If you want to create a new env file, set this to true
    log: true, // If you want to log the result, set this to true
  });
set.setEnv(); // This will create a new .env file depending on the options you set

CJS example:

const JsonToEnv = require("dynamic.envs").default;

const Set = {
    readFileFrom: path.join(__dirname, "..","FILE_NAME.json"),
    saveFileTo: path.join(__dirname, "..", ".env")
  }
const Options = {
    overWrite_Original_Env: false, // if you dont want to overwrite your original .env file, set this to true
    createJsonFile: false, // If you want to create a new json file, set this to true
    createEnvFile: true, // If you want to create a new env file, set this to true
    log: false // If you want to log the result, set this to true
  }
const sett = new JsonToEnv(Set,Options);
set.setEnv(); // This will create a new .env file depending on the options you set

Setting up Source and Destination

Option	Type	Required	Description
readFileFrom	String	Yes	The path to the json file you want to convert to .env file.
saveFileTo	String	Yes	The path to the .env file you want to create.

Options

Option	Type	Default	Description
overWrite_Original_Env	Boolean	False	If True, it will overWrite the orinal .env file
createEnvFile	Boolean	True	If True and overWrite_Original_Env is False is will create a new .env file however if overWrite_Original_Env is True it will oveWrite the original
createJsonFile	Boolean	False	If True, it will create a new .env.json file
log	Boolean	False	If True, it will log the result to the console

🚨 ALERT

• The interface Options_Set_Env has an important property called overWrite_Original_Env.
• By default this property is set to false. For safety reasons.
• This property once set to true will OVER WRITE the ORIGINAL .env file.(depends on the .env path)
• It's very important to keep set it as false if you want to keep the original .env file.

⚠️ WARNING

1. For while this is a very simple converter.
2. Thats a brand new project. So, still in basics development.
3. It does not check if the json file is valid.
4. It does not check if the json file is nested.
5. It does not check if the json file is empty.
6. It does not find .env file automatically.[YET]

🆕 Features Coming Soon

• Accept nested arrays.
• Accept nested objects of arrays.
• Find .env file automatically.

🤓 What technology are we using?

• TypeScript - Static tye checking

💪 Motivation

• I used to use those tools below to deal with .env files but I found them to be too boring sometimes annoing then I decided to use JSON instead, because I think they are more flexible, readble and easy to use. However, I was not able to find a way to convert JSON to .env file automatically. So I decided to write a tool to do that. I hope you will like it.

  • dotenv
  • config
