Serve multiple reactjs apps - Nodejs + Express + React

I'm trying to serve two separated Reactjs apps using Express.

App1

*Main app: displays different sets of data. Root front-end

*path: "/" (localhost:5000/)

App2

*Secondary App: User Dashboard, specific user-data.

*path: "/app" (localhost:5000/app)

I had a similar issue as: 1: Serving multiple react apps with client-side routing in Express

But that couldn't solve my problem.

Configuration files

App1 package.json

{
  "name": "app1",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@fortawesome/fontawesome-svg-core": "^1.2.4",
    "@fortawesome/free-solid-svg-icons": "^5.3.1",
    "@fortawesome/react-fontawesome": "^0.1.3",
    "axios": "^0.18.0",
    "classnames": "^2.2.5",
    "jwt-decode": "^2.2.0",
    "moment": "^2.22.0",
    "react": "^16.3.1",
    "react-dom": "^16.3.1",
    "react-image-gallery": "^0.8.11",
    "react-moment": "^0.7.0",
    "react-redux": "^5.0.7",
    "react-router-dom": "^4.2.2",
    "react-scripts": "1.1.4",
    "redux": "^3.7.2",
    "redux-thunk": "^2.2.0"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  },
  "proxy": "http://localhost:5000"
}

App2 package.json:

{
  "name": "app2",
  "version": "2.0.9",
  "private": true,
  "dependencies": {
    "@coreui/coreui": "^2.0.4",
    "@coreui/coreui-plugin-chartjs-custom-tooltips": "^1.2.0",
    "@coreui/icons": "0.3.0",

    "font-awesome": "^4.7.0",
    "prop-types": "^15.6.2",
    "react": "^16.4.2",
    "react-chartjs-2": "^2.7.2",
    "react-dom": "^16.4.2",
    "react-loadable": "^5.5.0",
    "react-router-config": "^1.0.0-beta.4",
    "react-router-dom": "^4.3.1",
    "react-test-renderer": "^16.4.2",
    "reactstrap": "^6.4.0",
    "simple-line-icons": "^2.4.1"
  },
  "devDependencies": {
    "babel-jest": "^23.4.2",
    "node-sass-chokidar": "^1.3.0",
    "npm-run-all": "^4.1.3",
    "react-scripts": "^1.1.5"
  },
  "scripts": {
    "build-css": "node-sass-chokidar --include-path ./node_modules ./src/scss -o ./src/scss",
    "watch-css": "npm run build-css && node-sass-chokidar --include-path ./node_modules ./src/scss -o ./src/scss --watch --recursive",
    "start-js": "react-scripts start",
    "start": "npm-run-all -p watch-css start-js",
    "build-js": "react-scripts build",
    "build": "npm-run-all build-css build-js",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  },
  "proxy": "http://localhost:5000",
  "homepage": "http://localhost:5000/app2",
}

server.js

app.use("/app2", express.static(path.join(__dirname, "app2/build")));
app.get("app2/*", (req, res) => {
  res.sendFile(path.join(__dirname + "/app2/build/index.html"));
});

app.use(express.static(path.join(__dirname, "app1/build")));
app.get("*", (req, res) => {
  res.sendFile(path.join(__dirname + "/app1/build/index.html"));
});

localhost:5000 successfully renders app1, but if I try localhost:5000/app2/ it actually looks for a route=/app2/ within app1, therefore I got a blank page.

PS: I also tried this solution, but again, no good results.

Thank you!

By default CRA build will assume that your application is served from root directory. This is the reason you saw a blank page - HTML was served, but requests for js and css failed. (Actually, in your case it succeded - index.html was returned because you have a catch-all at the bottom of your server.js file)

Now this can be parametrized in package.json

If your app will be served at /app2 you need to add

//package.json
{
  //...
  "homepage":"app2"
}

Then your output files will have propper reference. You can check it out

I am attaching link to CRA docs - homepage attribute
