*Setting GAE app.yaml for react-router routes produces "Unexpected token <"
errors.*
-----------------
In the development environment, all routes work when called directly.
localhost:5000 and localhost:5000/test produce expected results.
In GAE standard app.yaml functions for the root directory when the URL
www.test-app.com is called directly. ***www.test-app.com/test produces a
404 error.***
app.yaml #1
runtime: nodejs8
instance_class: F1
automatic_scaling:
max_instances: 1
handlers:
- url: /
static_files: build/index.html
upload: build/index.html
- url: /
static_dir: build
Configuring app.yaml to accept wildcard routes fails for all paths.
www.test-app.com/ and www.test-app.com/test produce an error *"Unexpected
token <"*. It appears that it is serving .js files as index.html.
app.yaml #2
runtime: nodejs8
instance_class: F1
automatic_scaling:
max_instances: 1
handlers:
- url: /.*
static_files: build/index.html
upload: build/index.html
- url: /
static_dir: build
*Steps to reproduce this issue:*
==============
Node: 10.15.0
npm: 6.4.1
gcloud init via Google Cloud SDK
npm init react-app test-app
npm install react-router-dom
Add router to index.js:
index.js
import {BrowserRouter as Router, Route} from 'react-router-dom';
import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';
ReactDOM.render(
<Router>
<App />
</Router>,
document.getElementById('root'));
serviceWorker.unregister();
Add routing to app.js:
app.js
import {Route} from 'react-router-dom'
import React, { Component } from 'react';
import logo from './logo.svg';
import './App.css';
class App extends Component {
render() {
return (
<div>
<Route exact path="/"
render={() => <div className="App">
<header className="App-header">
<img src={logo} className="App-logo" alt="logo" />
<p>
Edit <code>src/App.js</code> and save to reload.
</p>
<a
className="App-link"
href="https://reactjs.org";
target="_blank"
rel="noopener noreferrer"
>
Learn React
</a>
</header>
</div>} />
<Route exact path="/test"
render={() => <div className="App">
Hello, World!
</div>} />
</div>
);
}
}
export default App;

},

}
npm run build
gcloud app deploy
How do we convince app engine to allow a react SPA to process routes
directly?
