nestjs-custom-class-validators/lib/utils/commonDecoratorFunctions.js

This package contains a few custom validator I have found to be repetitive, So I made templates that handles both class-validator checks and Swagger configuration

"use strict";
Object.defineProperty(exports, "__esModule", { value: true });
exports.swaggerProp = exports.isArrayFn = exports.isUUIDFn = exports.isNumberFn = exports.isBooleanFn = exports.isEnumFn = exports.isStringFn = exports.notEmptyFn = void 0;
const swagger_1 = require("@nestjs/swagger");
const class_validator_1 = require("class-validator");
const each = true;
const notEmptyFn = (customKeys, isArray) => (0, class_validator_1.IsNotEmpty)(Object.assign({ message: `${customKeys}: Must not be empty` }, (isArray && { each: true })));
exports.notEmptyFn = notEmptyFn;
const isStringFn = (customKeys, isArray = false) => (0, class_validator_1.IsString)(Object.assign({ message: `${customKeys}: Must be a string` }, (isArray && { each })));
exports.isStringFn = isStringFn;
const isEnumFn = (customKey, validEnum, isArray = false) => {
    const message = `
  ${customKey}: Must be ${isArray ? "a list containing" : "either"} ${Object.values(validEnum).join(" or ")}`;
    return (0, class_validator_1.IsEnum)(validEnum, Object.assign({ message }, (isArray && { each: true })));
