I have a Json file with a properly value pairs. Can I import flags for my CLI from the JSON file or do they necessarily need to be hardcoded?

yes, you could import the json and perform a data transformation into flags

Can you please give a tiny example? @jdxcode

that's outside the scope of what we're able to provide support for

Hello @ShrutheeshIR,

Something like this should work (absolutely not tested):

flags.json

{
  "stringFlag": {
    ...
  },
  "numberFlag": {
    ...
  },
  "whateverFlag": {
    ...
  },
  ...
}

src/commands/doit.ts

import { Command } from '@oclif/command'
import * as Parser from '@oclif/parser'

import flagsJson from './flags.json'
 
type IFlag<T = any> = Parser.flags.IFlag<T>

const { stringFlag, numberFlag, whateverFlag, ...otherFlags } = flagsJson

class DoIt extends Command {
  static flags: typeof Command.flags = {
    stringFlag: stringFlag as IFlag<string>,
    numberFlag: numberFlag as IFlag<number>,
    whateverFlag: whateverFlag as IFlag,
    ...(otherFlags as Record<string, IFlag<any>>)
  }
}
