如何让网站在浏览器中自动运行“node index.js”？

我有一个要在 netlify 上自动运行的用于股票价格的 javascript 网络抓取程序。

为了让它运行，我必须在命令终端中输入“node index.js”。

但是..在将其上传到 netlify 后如何使其自动执行 - 无需输入“node index.js”？网页抓取/API 实践

这是我的第一个网络抓取项目——所以请理解——这可能是一个非常菜鸟的问题。

这是 index.js 文件

const request = require("request-promise");
const fs = require("fs");
const cheerio = require("cheerio");

基本上，javascript 会抓取该数据并将其发送到 CSV 文件，然后将其显示在页面中。
