Heroku 的 React 应用程序和 GraphQl 服务器部署问题

Question

我制作了一个与 prisma - graphql 服务器一起使用的 React 应用程序。服务器位于反应应用程序内。我想用 Heroku 部署它（第一次使用它）。当我部署到 Heroku 时，当我运行 heroku logs --tail

时出现此错误

我在我的项目中使用的是 yarn 而不是 npm 有人知道我需要做什么才能部署我的项目吗？因为我的项目不在 heroku 上运行ning，因为我在尝试打开已部署版本

时得到了这个

Application error
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail

我认为问题在于您正试图在 heroku 上启动反应开发服务器。您的 React 应用程序应作为静态 js 包提供，它是在您运行生产构建命令 npm run build.

之后生成的

看看 https://github.com/mars/create-react-app-buildpack，它专为这个用例开发，使它更容易。

如果您正在尝试部署整个堆栈（react + prisma + graphql server）...请查看详细介绍的 post。

希望对您有所帮助！
