Bracket-enum NPM

bracket-enum

If you're using Typescript, you will realize that the enum type under typescript is not so useful, so I created this repository to handle the enum type.

If you wanta see what you defined before, just move you mouse and hovering it.

How to use it

Install

yarn add bracket-enum

Define a BracketEnum

import { BracketEnum } from 'bracket-enum';
const STATUS = BracketEnum.of([
  // [CODE, [VALUE, DESC, EXTR]]
  ['AUDIT_WAIT', [1, 'pass', 'extra1']],
  ['AUDIT_PASS', [2, 'reject', 'extra2']],
]);

// --- or

const STATUS_2 = new BracketEnum([
  // [CODE, [VALUE, DESC, EXTR]]
  ['AUDIT_WAIT', [1, 'pass', 'extra1']],
  ['AUDIT_PASS', [2, 'reject', 'extra2']],
]);

I recommand you use BracketEnum.of instead of new for I often lost new in my code.

Basic Use

STATUS.getValueByCode('AUDIT_PASS'); // 2

STATUS.getDescByCode('AUDIT_WAIT'); // 'pass'

STATUS.getDescByValue(2); // 'pass'

STATUS.getAllValues(); // [1, 2]

// -- detect a value is match code
const currentState = 2;
STATUS.checkValueByCode('AUDIT_PASS', currentState); // true

Extend it by youself

Because I use class to create BracketEnum, so you can just extends it

// extend
class myEnums extends Dtnums {
  // ---
}
new myEnums([]);
myEnums.of([]);

e.g.

I use antd more often, so I add a function names toFormOption build in that could create the Options structure needed to generate Select in antd. If you need to define it, you can follow like below.

class myEnums extends Dtnums {
  // build in funtion aready, name toFormOptions
  toMyFormOptions(hasAll: boolean = false): any[] {
    const allOption = {
      key: null,
      value: null,
      label: '全部',
      extra: null,
    };
    // eslint-disable-next-line @typescript-eslint/no-unused-vars
    const result = this.configList.map(([code, [value, desc, extra]]) => {
      return {
        key: value,
        value,
        label: desc,
        extra,
      };
    });

    if (hasAll) {
      return [allOption, ...result];
    }
    return result;
  }
}
new myEnums([]);
myEnums.of([]);
