![]() ![]() What we’ll do is tell Heroku to build the React app after we push up the code, and we can do that by adding a “heroku-postbuild” script in the top-level (Express app’s) package.json."start": "set PORT=8080 HTTPS=true & react-scripts start", Express depends on the built client code in client/build, which we don’t have yet, and which we’d rather not check in to git.We need to check in the new client code.When you deploy the app with the git push heroku master command, git copies all the checked-in files up to Heroku. Go to and the app should be working! Now we can deploy the whole thing to Heroku. Make sure the Express app is running too: run yarn start from its folder as well. Now start up the React app by running yarn start inside the client folder. I also recommend opening up src/index.js and removing the call to registerServiceWorker() at the bottom, since it can cause some confusing caching issues (like preventing you from accessing the API endpoints in a browser after you load the React app once). get ( '/api/passwords', ( req, res ) => join ( _dirname, 'client/build' ))) // Put all API endpoints under '/api' app. Call it rando or whatever you want.Ĭonst express = require ( 'express' ) const path = require ( 'path' ) const generatePassword = require ( 'password-generator' ) const app = express () // Serve static files from the React app app. Make a parent directory to contain everything. Just a quick disclaimer: this is just meant as a demo! I don’t recommend using some random internet thing that generates passwords on the server to generate your own real passwords ) Create the Express App ![]() Every time you load the app or click Get More you’ll get 5 random paswords. (On a Mac with Homebrew, just brew install heroku). Heroku comes with a commandline command they call a “toolbelt.” Follow the instructions here to install it. If you don’t have one already, go here and sign up. Heroku is easy to deploy to and free to get started with. We’ll build the Express server to serve React’s static files in addition to providing an API, and then deploy it to Heroku. This article will cover how to keep them together.
