Js - 使用运算符作为字符串来评估数学表达式的替代方法

我有一个库,它具有基于某些字段过滤对象的功能(每个字段都有特定类型的类型 - 有关https://github.com/jy95/mediaScan/wiki 的更多信息)

最大的问题是处理来自多个来源的数字属性

// to handle number operations
export interface NumberExpressionObject {
    operator: "==" | ">" | "<" | ">=" | "<=";
    number: number;
}

// additional Properties
export interface AdditionalProperties {
    type: AdditionalPropertiesType;
    name: string;
    value: boolean | string | string[] | number | NumberSearchSyntax;
}

例如 :

expect((libInstance.filterTvSeries({
            additionalProperties: [
                {type: "number", name: "whateverFieldThatDoesn'tExist", value: "<50"},
                {type: "number", name: "AnotherField", value: undefined},
                {type: "number", name: "AnotherField2", value: "<=25"},
                {type: "number", name: "AnotherField3", value: ">25"}, …

Github Actions - 未处理的拒绝 SequelizeConnectionError:启动数据包中未指定 PostgreSQL 用户名

我为 CI/CD 设置了 Github Actions,但我在数据库连接方面遇到了困难。
由于sequelize允许指定另一个数据库url(使用“use_env_variable”选项),我更新了我的配置,如下所示:

{
  "test": {
    "dialect": "postgres",
    "schema": "exercises_library",
    "logging": false,
    "use_env_variable": "DATABASE_URL"
  },
  "production": {
    "dialect": "postgres",
    "schema": "exercises_library",
    "logging": false,
    "use_env_variable": "DATABASE_URL"
  }
}

所以我在 Github Actions 中编写了我的工作流程:

name: Source Code CI/CD

on:
  push:
    branches:
      - master
  pull_request:
    branches:
      - master

pdfMake - 无法打开文件

我在 Nodejs 上使用了这个模块:https : //github.com/bpampuch/pdfmake

这是我创建它的代码:

    const fonts = {
    Roboto: {
        normal: './fonts/Roboto-Regular.ttf',
        bold: './fonts/Roboto-Medium.ttf',
        italics: './fonts/Roboto-Italic.ttf',
        bolditalics: './fonts/Roboto-Italic.ttf'
    }
};

let PdfPrinter = require('pdfmake/src/printer');
let printer = new PdfPrinter(fonts);
let fs = require('fs');


module.exports.generateFile = function (data,callback) {

    let fileName = "Logins_" + data[0]["userLogin"] + ".pdf";
    let filePath = __dirname + "/files/" + fileName;

    let logins = [ ['userLogin', 'softwarePassword', 'softwareName'] ];
    for (let obj of data) {
        let arr = [];
        for(let x in obj){
            arr.push(obj[x]); …
