How to create Node.js Express app serving a Vue.js SPA?

I'm trying to set up a Node.js project that uses Express to provide a few backend APIs and serve a SPA built with Vue.js.

When I use the Vue cli to initialize a project, I get e.g. src/main.ts main file and commands npm run serve to run a dev server and watch for changes and npm run build to build a production release.

When I use the Express application generator to create a project, I get ./app.js main file and npm start to start the server and watch for changes.

How can I combine these into a single project, both served by the same Express server? Preferably so that a single command would watch + update changes to both server and client? I want to use Vue single file components and TypeScript, which (probably?) require a build step.

(I don't need dynamic server-side rendering of Vue templates, just the static SPA app provided. I prefer TypeScript, but JavaScript answers are fine as well.)

These will be different for your dev and prod environments...

For development look into concurrently - it basically allows you to create a single script in your package.json to start both the client and server concurrently and will watch for changes etc...

For production, you would need something like this in your app.js:

if (process.env.NODE_ENV === 'production') {
  app.use(express.static('client/build'));

  const path = require('path');
  app.get('*', (req, res) => {
    res.sendFile(path.resolve(__dirname, 'client', 'build', 'index.html'));
  });
}

(The code above assumes that your directory structure has a client folder with a build folder after having run npm run build I'm more familiar with React than Vue... but the logic should be the same...)
