我已经打了一个项目，我一直在努力的路障，我想知道如果有人可以帮助我与此。P5.js，节点和Twitter的API
因此，我试图开发一个node.js应用程序，它使用HTML表单查询Twitter API - 然后使用检索的数据（以JSON形式）在P5.js草图中显示推文。
到目前为止，我已经能够使用查询API的表单并将拉动的推文写入JSON文件。 单独，我也能够将JSON文件拉入P5并按我认为合适的方式处理数据。
问题是 - 我的最终游戏是我希望它是一个无缝的过程，我需要初步向用户提供草图，加载默认数据集。然而，我需要的形式来更新动态草图（使用AJAX我想象？）
我的问题是：是否有一个不太复杂的方式来实现？我正在猜测使用JQuery & Ajax的组合，但我很疲惫，试图辨别什么会运行客户端，什么会运行服务器端。
TL; DR - 我想传递用户输入的数据作为参数来查询Twitter API并异步更新p5.js草图。
我已经附上了我正在使用的代码，如果有人能够帮助我，我将非常感激，因此我不必拔出更多的头发！即使把我指向正确的方向也会有很大的帮助。
感谢提前:)
