fill-in v1.0.2

fill-in.js

Interactive fill in via stdin and generate JSON from the input, based on JSON schema.

Install

$ npm i fill-in

TL;DR:

• This is a JavaScript object generator.
• Takes JavaScript object in JSON Schema format that defines the configuration file format.
• Interactively prompts the userer and generates a configuration file according to the JSON Schema and user input.

Example

import { fillIn } from 'fill-in';

async function main() {
  const schema = {
    "title": "Profile",
    "type": "object",
    "properties": {
      "firstName": {
        "type": "string",
        "description": "your first name",
        "examples": [ "Jane" ],
        "minLength": 1,
        "order": 10
      },
      "lastName": {
        "type": "string",
        "description": "your last name",
        "examples": [ "Doe" ],
        "minLength": 1,
        "order": 20
      },
      "age": {
        "type": "integer",
        "description": "your age",
        "examples": [ 30 ],
        "order": 30
      },
      "gender": {
        "type": "string",
        "description": "your gender",
        "enum": [ "male", "female", "other" ],
        "order": 40
      },

        "default": false
      }
    },
    "required": [ "firstName", "lastName", "public" ]
  };
