在Google App Engine上部署create-react-app [英] Deploy create-react-app on Google App Engine

问题描述

我正尝试部署使用 create-react-app 创建的应用Google App Engine。

I'm trying to deploy my app created using create-react-app on Google App Engine.

我的应用在本地运行良好（ npm start 和 npm运行build& serve -s build ）。
但是，在Google App Engine上部署的应用程序仅显示index.html，并且不会调用我的反应代码。

My app works well on local (both npm start and npm run build & serve -s build). However, the deployed app on Google App Engine shows only the index.html, and does not call my react code.

Chrome开发者控制台显示未捕获的语法错误：意外的令牌< 。

The Chrome Developer Console is showing Uncaught SyntaxError: Unexpected token <.

此外，我在console.cloud.google.com上发现已部署应用未包含构建文件夹。

Also, I found on console.cloud.google.com that the deployed app did not include the build folder. Is this correct?

任何人都可以解决这个问题吗？

Anyone can solve this problem?

这是我的package.json：

Here is my package.json:

{
  "name": "XXXXX",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^16.8.2",
    "react-dom": "^16.8.2",
    "react-ga": "^2.5.7",
    "react-router-dom": "^4.3.1",
    "react-scripts": "2.1.5"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
 },
  "eslintConfig": {
    "extends": "react-app"
  },
  "browserslist": [
    ">0.2%",
    "not dead",
    "not ie <= 11",
    "not op_mini all"
  ]
}

这是我的app.yaml。

Also, here is my app.yaml.

runtime: nodejs10

handlers:
- url: /.*
  static_files: build/index.html
  upload: build/index.html
- url: /
  static_dir: build

推荐答案

由于多次搜索网络，我发现我的应用程序的路由系统是原因。

As a result of searching the web many times, I found that the routing system of my react app was the cause.

如这篇文章指出，我们在编写app.yaml时需要谨慎。
如果我们首先编写以下项目，则GAE对于所有查询都返回 build / index.html ，包括对 / static / js 和 / static / css 。

As this post states, we need to be careful about authoring app.yaml. If we write the following item first, GAE returns build/index.html for all queries, including access to /static/js and /static/css.

- url: /
  static_files: build/index.html
  upload: build/index.html

create-react-app 为 npm run build 创建一个构建文件夹和静态子文件夹。
因此，我必须像这样更具体地编写我的app.yaml：

create-react-app creates a build folder and static subfolders for npm run build. Thus, I had to write my app.yaml more specific like this:

handlers:
  - url: /static/js/(.*)
    static_files: build/static/js/\1
    upload: build/static/js/(.*)
  - url: /static/css/(.*)
    static_files: build/static/css/\1
    upload: build/static/css/(.*)
  - url: /static/media/(.*)
    static_files: build/static/media/\1
    upload: build/static/media/(.*)
  - url: /(.*\.(json|ico))$
    static_files: build/\1
    upload: build/.*\.(json|ico)$
  - url: /
    static_files: build/index.html
    upload: build/index.html
  - url: /.*
    static_files: build/index.html
    upload: build/index.html
