Javascript 在Django服务器上使用webpack运行React应用程序时出现问题

我正在使用Django作为后端构建一个web应用程序，并希望实现一个ReactJS框架前端。到目前为止，我拥有的每个应用程序都可以独立地正常运行。我还实现了webpack，它似乎配置正确，因为它将在本地主机上运行我的ReactJS应用程序。作为webpack（以及一般的web开发）的新手，我不确定如何在Django本地服务器（127.0.0.1:8000）上运行React。我从许多论坛上了解到，javascript文件需要打包，然后读入django应用程序。以下是相关文件：

与Django反应

这些不应在同一台服务器上运行。如果您希望连接它们，您应该能够创建配置文件，并说如果我点击的url是xx.com/users，否则如果是开发，则是localhost:8000/users。为什么您需要两者都在同一台服务器上运行？

我们使用django模板呈现我们的网页包包包（对于Vue应用程序，但这是相同的基本思想）。

您已将网页包配置为开发模式。这意味着您要运行webpack开发服务器。但您需要将前端应用程序构建成一个捆绑包，然后将此捆绑包用于服务器端。只需删除

devServer

部分。此外，您还可以删除这个

process.env.NODE_env='production'并将
模式更改为
生产模式
。此操作将您的
process.env.NODE_env
设置为
production
（）

如果您需要在开发模式下测试您的应用程序，您可以将
代理添加到package.json中，并使用后端地址，前后分开运行

解决方案：

添加一个npm命令：
“build:prod”：“&&mv/index.html//templates&&mv/*/static”

将此添加到Django应用程序设置：

STATIC_URL = '/static/'
STATICFILES_DIRS = (
  os.path.join(BASE_DIR, 'static'),
)

我们需要能够通过django模板运行它，因为我们的应用程序托管在python托管站点上。为了让它工作，前端应用程序应该通过webpack进行捆绑，然后由django应用程序提供服务。您建议我们如何处理此问题？我按照您所说的步骤进行了编译，但没有任何更改。编译后，您需要将编译后的文件添加到Django app index.htmlw我们认为目前正在这样做，但显然我们没有。你建议怎么做？没什么难的。只需制作捆绑包，将其移动到Django中的/static/文件夹中，并将这样的链接添加到您的主模板
@Spencer我已经为我的回答添加了另一个可能的解决方案您是否使用了webpack\u loader中的render\u捆绑包功能？您已导入webpack\u loader，但未使用render\u bundle加载react！
