nestjs-custom-class-validators/lib/decorators/number.decorator.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.CustomNumberValidator = void 0;
const class_transformer_1 = require("class-transformer");
const class_validator_1 = require("class-validator");
const validatorTransformers_1 = require("../transformers/validatorTransformers");
const commonDecoratorFunctions_1 = require("../utils/commonDecoratorFunctions");
function MinNumberFN(min, key, isArray = false) {
    return (0, class_validator_1.Min)(min, Object.assign(Object.assign({}, (isArray && {
        message: `${key}: Must be a list of numbers greater or equals ${min}`,
    })), (!isArray && {
        message: `${key}: Must be greater or equals ${min}`,
    })));
}
function MaxNumberFN(max, key, isArray = false) {
    return (0, class_validator_1.Max)(max, Object.assign(Object.assign({}, (isArray && {
        message: `${key}: Must be a list of numbers less or equals ${max}`,
    })), (!isArray && {
        message: `${key}: Must be less or equals ${max}`,
    })));
}
function CustomNumberValidator(details) {
    const { optional, defaultValue, description, isArray, min, max } = details;
    const mySwaggerProp = (0, commonDecoratorFunctions_1.swaggerProp)({
        optional,
        description,
        defaultValue,
        type: 'number',
        isArray,
    });
    return function (target, key) {
        optional ? (0, class_validator_1.IsOptional)()(target, key) : (0, commonDecoratorFunctions_1.notEmptyFn)(key)(target, key);
        min && MinNumberFN(min, key, isArray)(target, key);
